Battery Analysis Services

Battery analysis encompasses a suite of systematic, scientific techniques designed to characterize, evaluate, and optimize the structural, chemical, electrochemical, thermal, and mechanical properties of batteries across their entire life cycle. Unlike superficial performance checks, battery analysis delves into the microscale and atomic-level behaviors of battery components—including cathodes, anodes, electrolytes, separators, and binders—to unlock critical insights into functionality, degradation mechanisms, safety risks, and performance limitations. It serves as the foundational science enabling advancements in battery technology, ensuring that energy storage devices meet the rigorous demands of modern applications, from consumer electronics and electric vehicles to grid-scale energy storage systems.

At its core, battery analysis integrates principles from materials science, electrochemistry, thermodynamics, and mechanical engineering to generate quantifiable data and actionable observations. For instance, analyzing a lithium-ion battery's cathode via X-ray diffraction (XRD) can reveal crystallographic defects that reduce ion storage capacity, while electrochemical impedance spectroscopy (EIS) can identify internal resistance bottlenecks that limit charging speed and energy efficiency. These techniques are not isolated; they work in tandem to provide a holistic understanding of battery behavior, from raw material quality control to end-of-life degradation analysis. By quantifying parameters such as ion diffusion rates, electrode porosity, electrolyte conductivity, and thermal stability, battery analysis bridges the gap between theoretical battery design and real-world performance.

Battery analysis is critical for addressing the most pressing challenges in energy storage: enhancing energy density, extending cycle life, improving safety, and reducing costs. For example, elemental analysis of cathode materials using inductively coupled plasma optical emission spectroscopy (ICP-OES) can detect trace metal impurities—such as iron or copper—that accelerate electrolyte decomposition and shorten battery lifespan, with detection limits as low as parts per billion (ppb). Similarly, structural analysis via scanning electron microscopy (SEM) can visualize microscale cracks in anodes that form during repeated charge-discharge cycles, explaining capacity fade and guiding the development of more durable electrode materials. Without rigorous battery analysis, advancements in next-generation batteries—including solid-state, sodium-ion, and lithium-sulfur technologies—would remain theoretical, as the complex interactions between components cannot be fully understood through performance testing alone.

We provide battery structural analysis services that evaluate the physical integrity and microscale structure of battery components and complete battery cells, identifying defects and structural factors that impact performance and safety. Our structural analysis includes high-resolution imaging and quantitative characterization of cathodes, anodes, separators, and battery packs, using techniques such as SEM, TEM, X-ray CT, and laser scanning microscopy.

For individual battery components, we offer detailed structural characterization: cathode particle size and shape analysis, anode porosity and layer thickness measurement, and separator pore size distribution and uniformity testing. Using SEM with elemental mapping capabilities, we can visualize the distribution of active materials and binders in electrodes, identifying areas of uneven mixing that reduce ion diffusion and capacity. X-ray CT scanning provides 3D visualization of intact battery cells, revealing internal defects such as electrode misalignment, separator tears, air bubbles in electrolytes, and voids in jelly rolls—all of which can lead to short circuits or performance degradation. We also conduct structural failure analysis, disassembling failed batteries to identify the root cause of structural defects, such as electrode delamination, separator puncture, or cell casing damage.

Battery Chemical Analysis Services

We provide battery chemical analysis services that quantify the chemical composition of battery components, detect impurities, and identify chemical degradation mechanisms, ensuring material quality and optimizing battery performance. Our chemical analysis leverages techniques such as ICP-OES, ICP-MS, GC-MS, FTIR, XRD, and Karl Fischer titration to deliver precise, comprehensive results.

Raw material chemical analysis includes purity testing of lithium carbonate, nickel sulfate, graphite, and electrolyte salts, with detection of trace metal impurities (e.g., iron, copper, lead) and non-metallic contaminants (e.g., sulfur, chlorine) at ppb levels. Cathode and anode chemical analysis verifies the elemental composition and stoichiometry of active materials—such as NMC (nickel-manganese-cobalt) or LFP (lithium-iron-phosphate) cathodes—ensuring alignment with design specifications. Electrolyte analysis includes solvent and salt concentration measurement, additive identification, and water content testing, as well as the detection of decomposition byproducts that indicate degradation. We also conduct chemical analysis of degraded batteries to identify changes in electrode and electrolyte composition over time, linking specific chemical reactions to capacity fade, internal resistance increase, or safety risks.

Battery Electrochemical Analysis Services

We provide battery electrochemical analysis services that evaluate the electrical performance, reaction kinetics, and degradation behavior of batteries, optimizing capacity, efficiency, and cycle life. Our electrochemical analysis techniques include charge-discharge cycling, EIS, CV, and galvanostatic intermittent titration technique (GITT), supported by high-precision battery cyclers and impedance analyzers.

Charge-discharge cycling tests measure key performance parameters such as nominal capacity, energy density, cycle life, coulombic efficiency, and charging/discharging rate capability, conducted under controlled temperature and current conditions to simulate real-world use. EIS quantifies internal resistance components—including electrolyte resistance, SEI resistance, and charge transfer resistance—identifying bottlenecks that limit energy efficiency and charging speed. CV maps the oxidation-reduction reactions at the anode and cathode, identifying optimal operating voltages and detecting unwanted side reactions that reduce performance or safety. GITT measures lithium-ion diffusion coefficients in electrodes and electrolytes, providing insights into ion mobility and how it impacts charging speed and capacity. We also evaluate the performance of battery management systems (BMS) through electrochemical testing, ensuring that charging and discharging protocols are optimized to minimize degradation.

Our thermal analysis techniques include DSC, ARC, IR imaging, and thermal gravimetric analysis (TGA), enabling comprehensive characterization of thermal properties across a wide temperature range.

DSC measures the heat absorbed or released during chemical reactions—such as electrolyte decomposition, electrode phase transitions, and SEI formation—identifying critical temperatures where thermal stability is compromised. ARC evaluates thermal runaway behavior, simulating worst-case scenarios by monitoring self-heating, temperature rise rate, and pressure buildup during exothermic reactions, providing critical data for safety design. IR imaging generates thermal maps of battery cells and packs, detecting hotspots that indicate localized overheating due to defects, uneven current distribution, or poor thermal management. TGA measures the thermal decomposition of electrode materials, binders, and electrolytes, quantifying weight loss and decomposition temperatures to assess thermal stability. We also evaluate the effectiveness of thermal management systems (TMS), ensuring that batteries remain within safe operating temperatures (typically 20-40°C) under all use conditions.

Battery Mechanical Testing Services

We provide battery mechanical testing services that evaluate the mechanical strength, structural integrity, and durability of batteries and their components, ensuring they can withstand the physical stresses of manufacturing, transportation, and use. Our mechanical testing includes impact testing, compression testing, tension testing, vibration testing, and penetration testing, conducted using specialized equipment to simulate real-world stress conditions.

Impact testing simulates collisions or drops, measuring the battery's response to sudden mechanical shock—including casing integrity, leakage, and short circuit risk. Compression testing evaluates the battery's ability to withstand compressive forces, such as those encountered during installation or transportation, measuring the force required to cause structural failure. Tension testing assesses the strength of separators, electrodes, and casing materials, ensuring they can withstand the expansion and contraction of electrodes during charge-discharge cycles without tearing or breaking. Vibration testing simulates the vibrations experienced during transportation or use (e.g., in electric vehicles), evaluating the battery's structural integrity and performance after prolonged vibration exposure. Penetration testing simulates worst-case scenarios (e.g., nail puncture), assessing the risk of short circuits and thermal runaway due to mechanical damage, providing critical data for safety design optimization.
