Battery Forensics


WMG’s Forensic Analysis of Batteries Laboratory (FAB Lab) focusses on understanding and evaluating the performance of batteries over time. One of our main drivers is investigating root causes of degradation over multiples scales. This applies to battery packs, modules and individual cells, finally to cell components (electrode materials, separators and electrolytes).


Our approach covers a whole array of electrochemical testing to characterise how well batteries charge and discharge as a function of cycle life. We also analyse post-mortem components to assess advanced degradation as well as applying operando measurements to look at real-time phenomena. This includes structural dynamics within electrodes, changes to surface chemistries and interfaces and monitoring the compositional changes within the electrolyte solvents.

WMG-FAB delivers case studies into investigations of commercial batteries and devices and works with industry to better understand batteries. Part of this includes scenarios where the batteries are operated beyond recommended usage parameters.

A deeper understanding across multiple scales of battery performance, and how this relates to microstructure, is key to revealing key degradation stages. This will ultimately facilitate the manufacturing of better and safer batteries.

Our laboratory has a custom-made glove box set-up to compartmentalise module and cell deconstruction with video and microscopy capability (all under argon.) This includes airless transfer options to extend to SEM, TEM and SIMS.

Equipment / Facilities :

  • Serial glove-box for disassembly and transfer of modules and multiple cell formats.
  • Airless transfer devices to enable subsequent mobility of sensitive samples from argon atmospheres to SEMs, TEMs and SIMS microscopy equipment.
  • Hyphenated GC-MS, FTIR and STA for comprehensive thermal characterisation of battery components.
  • Optical microscopy to high resolution SEM (FEG and Environmental) to deeply investigate microstructures.
