Standard Operating Procedures (SOPs)
Sector
Equipment Robotics and Advanced Manufacturing
Description
Standard operating procedures (SOPs) are written, step-by-step instructions that define how to perform a specific laboratory task safely, reproducibly, and in compliance with regulatory or quality requirements. As a hard skill it requires writing SOPs clearly enough for a trained but unfamiliar operator to follow without ambiguity, incorporating safety precautions and equipment-specific details, and maintaining version control as procedures evolve. Battery R&D labs apply SOPs to instrument operation, sample preparation, and cell assembly, ensuring that experimental results are comparable across operators and time and that safety-critical steps — such as lithium metal handling and high-voltage cell formation — are never improvised.

Description
Statistical and data analysis turns the millions of measurements coming off battery production lines into actionable conclusions about yield, capability, and reliability. As a hard skill it requires fluency in descriptive and inferential statistics, regression, and time-series analysis, plus practical use of Python, R, or JMP to crunch real datasets. Engineers apply these tools to qualify new test equipment with gauge R&R studies, build acceptance sampling plans for incoming cell shipments, and prove (or disprove) that a process change actually moved the mean.
Title
Structural Analysis
Sector
Equipment Robotics and Advanced Manufacturing
Description
Structural analysis determines whether battery pack enclosures, mounting systems, and cell interconnect structures can withstand the mechanical loads — vibration, shock, crush, and thermal cycling — imposed by their operating environment without yielding, fracturing, or losing fatigue life. As a hard skill it requires setting up and solving finite-element models in tools such as ANSYS or Abaqus, interpreting stress and displacement results against material allowables, and translating automotive or aerospace load cases into analysis inputs. Engineers apply these techniques during pack structural design, regulatory crash certification (UN ECE R100, FMVSS 305), and root-cause analysis of field failures where a structural member cracked or deformed in service.
Title
Structural Geology
Sector
Mining
Description
Structural geology studies the deformation of rock — folds, faults, foliations, and shear zones — and how those structures control ore distribution and rock-mass behavior. In mining it guides exploration targeting, mine design, ground control, and the interpretation of grade continuity within the orebody. Skilled structural geologists translate field and core observations into the kinematic and stress models that underpin both resource and geotechnical decisions.
Title
Structured Query Language (SQL)
Sector
Computational
Description
SQL is the universal language for relational data — battery production teams use it to query MES databases, pull cell-formation history, audit pack genealogy, and feed analytics platforms with structured data. As a hard skill it requires fluency in joins (inner, outer, anti), window functions, aggregation patterns, query plan reading, and the index-design discipline that determines whether a yield query returns in 200ms or 20 minutes. Engineers and analysts apply this when reconstructing a cell's life from manufacture to field failure, when pulling a daily yield extract for the morning standup, and when designing the schema that ties pack IDs to cell IDs to test records.
Title
Supply Chains & Logistics
Sector
Supply Chains
Description
Supply chain logistics is the end-to-end coordination of sourcing, manufacturing, transportation, and distribution required to deliver products to customers at the right cost and service level. The discipline spans S&OP, network design, procurement, transportation management, customs and trade compliance, and supplier risk management. Recent disruptions have elevated supply chain from a back-office function to a board-level strategic concern, especially in critical-minerals, defense, and energy supply chains.

Synchrotron operations involves planning, executing, and analyzing experiments at large-scale X-ray light sources, where access to high-flux, tunable, highly collimated X-ray beams enables techniques unavailable in the lab — high-resolution diffraction, total scattering, SAXS, XAS, and sub-micron imaging. As a hard skill it requires writing competitive beamtime proposals, setting up in situ and operando sample environments, operating beamline controls and detectors during limited allocated time, and processing large diffraction or spectroscopy datasets post-experiment. Battery researchers exploit synchrotron access for operando studies of structural and chemical changes in cathodes and electrolytes during charge and discharge at time and length scales that decisively resolve degradation mechanisms.
Title
Tableau
Sector
Computational
Description
Tableau is the visualization platform favored by analytics teams that want polished, interactive dashboards without writing front-end code — used for battery yield dashboards, quality KPIs, supply-chain analytics, and executive reporting. As a hard skill it requires fluency in data prep (Tableau Prep), calculated-field authoring (LOD expressions, table calcs), dashboard design for non-technical audiences, and the publishing model (Tableau Server/Cloud) that gets dashboards into stakeholders' hands. Analysts apply this when building a yield-trend dashboard for plant managers, when creating an interactive defect-Pareto for quality reviews, and when surfacing field-warranty data to product engineering through filterable visuals.

Description
Thermogravimetric analysis (TGA) records the mass of a sample as a function of temperature or time under a controlled atmosphere, detecting decomposition, oxidation, moisture loss, and volatilization events from the mass-loss profile and its derivatives. As a hard skill it requires selecting the appropriate gas atmosphere, calibrating the balance and temperature sensor with certified standards, and correlating mass-loss steps with derivative curves and complementary techniques such as DSC or evolved-gas mass spectrometry. Battery researchers apply TGA to determine organic binder content in electrodes, measure residual solvent after drying, characterize cathode thermal stability, and assess carbon content in active materials.
Title
Tomography
Sector
Research and Development
Description
X-ray tomography acquires a series of 2D projection images around a sample and reconstructs them into a 3D volume, revealing internal pore networks, crack patterns, and microstructural heterogeneity without sectioning the sample. As a hard skill it requires optimizing source energy and detector settings for the material density, achieving adequate sample-to-detector contrast, and using reconstruction and segmentation software such as Dragonfly, Avizo, or ImageJ to extract quantitative 3D metrics including porosity, tortuosity, and particle size. Battery researchers apply tomography to visualize electrode architectures and degradation, track lithium plating and void formation in cycled anodes, and measure tortuosity factors that govern electrolyte transport and rate performance.
Title
Transmission Electron Microscopy (TEM)
Sector
Research and Development
Description
Transmission electron microscopy (TEM) passes a high-energy electron beam through an electron-transparent specimen and forms images or diffraction patterns that reveal atomic-scale crystal structure, defects, interfaces, and chemical composition via coupled EELS or EDX. As a hard skill it requires preparing specimens thin enough for electron transmission via FIB lamella or ion-milling, aligning the beam and selecting correct imaging conditions (bright-field, dark-field, HRTEM, HAADF-STEM), and interpreting lattice images and diffraction patterns against reference structures. Battery researchers apply TEM to resolve atomic-scale structural changes in cycled cathode particles, characterize SEI layer thickness and composition, and identify precipitated phases at grain boundaries in solid electrolytes.
Title

Sector
Mining
Description
Underground mining extracts ore through shafts, declines, and drifts using methods such as room-and-pillar, cut-and-fill, sublevel stoping, and block caving, each tailored to the geometry, grade, and rock mechanics of the specific orebody. As a hard skill it requires understanding ground-support design, ventilation requirements, blasting and mucking cycles, and the logistics of moving people and materials safely through confined, often wet and gassy environments. Underground mining is the method of choice for deep, high-grade, or geometrically complex deposits, and demands disciplined adherence to safety culture across every shift to manage the ground, gas, and equipment hazards inherent in the underground environment.
Title
Unit Operations
Sector
Refining & Chemical Processing
Description
Unit operations are the discrete, physical processing steps — distillation, absorption, extraction, filtration, crystallization, evaporation, drying, heat exchange, and reaction — that chemical and refining engineers assemble into process flowsheets. As a hard skill it requires understanding the governing transport phenomena (mass, heat, and momentum transfer) that size each operation, selecting equipment based on feed characteristics and product specifications, and troubleshooting performance deviations from design. Practitioners apply unit operations knowledge throughout the process life cycle: sizing a distillation column in preliminary design, diagnosing poor separation in an operating refinery, and optimizing energy consumption by improving heat integration across multiple unit operations.
Title
VBA
Sector
Computational
Description
Visual Basic for Applications (VBA) is the macro language that runs inside Microsoft Office — battery quality teams still use it heavily for Excel-based test reports, automated PPAP documentation, and the one-off automations that bridge between an analyst's workbook and a vendor's data extract. As a hard skill it requires fluency in the Excel object model (Workbooks, Worksheets, Ranges, charts), the editor's debugging tools, and the discipline of writing macros that won't break when the source data shape shifts. Analysts apply this when automating the daily-yield rollup in Excel, when generating PPAP test report templates from raw cell-formation data, and when stitching Excel reports together for engineering reviews where Tableau and Power BI aren't available.
Title
Vacuum Pumps
Sector
Research and Development
Description
Vacuum pumps — rotary vane, turbomolecular, scroll, cryogenic, and ion pumps — remove gas from a system to achieve the pressures required by electron microscopes, thin-film deposition equipment, and glove-box regeneration cycles. As a hard skill it requires selecting the pump type and staging for the target pressure range, performing routine maintenance such as oil changes, trap cleaning, and rotor inspection, and troubleshooting leaks with residual gas analyzers or helium leak detectors. Battery researchers rely on vacuum systems for SEM and TEM operation, ALD and sputter deposition, and electrolyte degassing, where inadequate vacuum allows residual gases to contaminate samples, degrade film quality, and generate background signals in analytical instruments.
Title
Ventilation
Sector
Mining
Description
Mine ventilation supplies fresh air to working faces and removes heat, dust, diesel particulate, and harmful gases such as methane, carbon monoxide, and radon. Ventilation engineers design primary and auxiliary fan circuits, model airflow networks, and balance the system as workings advance, all while meeting strict regulatory air-quality limits. The discipline is foundational to underground productivity and one of the largest single energy consumers on a typical underground mine.
Title
Verilog & VHDL
Sector
Computational
Description
Verilog and VHDL are the hardware description languages used to design the FPGAs and ASICs that increasingly appear inside battery management systems — for high-speed cell-balancing, parallel cell-voltage sampling, and the real-time fault-detection logic that microcontrollers can't service fast enough. As a hard skill it requires fluency in synthesizable HDL subsets, testbench authoring, simulator workflows (ModelSim, Verilator, Vivado), and the timing-closure discipline that distinguishes hobby HDL from production silicon. Hardware engineers apply this when designing the FPGA front-end that samples 96 cells simultaneously on a pack controller, when prototyping an ASIC for next-generation BMS, and when implementing the safety-monitor logic that watchdogs the BMS microcontroller.

Description
Welding and joining techniques — laser welding, ultrasonic welding, resistance welding, mechanical fastening, conductive adhesives — connect the electrical and structural components of cells, modules, and packs. As a hard skill it requires understanding joint geometry, weld parameter development for thin dissimilar metals like aluminum and copper, and non-destructive inspection of completed joints. Process engineers apply this knowledge when developing tab-to-busbar welding recipes, qualifying ultrasonic weld stations, and root-causing pack-level resistance issues that trace back to a marginal weld.
Title
Wiring
Sector
Electrical
Description
Wiring — selecting conductor size, color-coding, terminating, routing, labeling — is the daily detail work that turns a schematic into a functioning electrical installation on a battery production line or in a pack. As a hard skill it requires NEC table reading for ampacity, understanding stranded vs solid for vibration and flex life, proper crimp technique with calibrated tools, and the documentation discipline so the next electrician can trace a wire back to its source. Electricians apply this on every panel build, every cable harness on a pack-test rig, and every re-pull when a sensor fails and has to be replaced without disrupting the rest of the harness.
Title
Workplace Safety

XRD is one of the most widely used techniques in materials science, from cement and ceramics to batteries, alloys, and pharmaceuticals.
Title
X-ray Fluorescence (XRF)
Sector
Research and Development
Description
X-ray fluorescence (XRF) spectrometry determines elemental composition by exciting a sample with X-rays and measuring the characteristic fluorescence energies emitted by each element, providing rapid, multi-element, largely non-destructive analysis of solids, powders, and liquids. As a hard skill it requires selecting wavelength-dispersive (WDXRF) or energy-dispersive (EDXRF) mode based on required resolution and throughput, preparing samples with consistent geometry and matrix, and applying fundamental-parameters or empirical calibrations for accurate quantitation. Battery researchers apply XRF to screen cathode powder stoichiometry, verify element ratios in synthesized materials, and perform incoming quality checks on active materials and current-collector foils without the sample digestion required by wet-chemical methods.
