Batteries

Li-ion batteries have been a key enabling technology over the last decade and are considered integral to future green energy developments. The use of characterisation methods is vital to both ensure the quality of the product and for the development of the next generation of batteries. Oxford Instruments provides a range of detectors and analytical systems which are designed with battery applications from research through to manufacturing in mind.

Manufacturing & Quality Control

The materials used in the production of Li-ion batteries must be of high purity in order for the final products to have the specified performance and lifetime. High purity also prevents dangerous failures caused by metallic particles penetrating isolating barriers. Quality control and monitoring of materials throughout the manufacturing process is crucial as even very small amounts of contaminants can have catastrophic consequences.

AZtecBattery provides a fully automated solution for identifying and characterising contaminants in powder materials. Understanding the sources of contamination is the first step towards eliminating them and ensuring the quality of the manufactured product.

Research & Development 

The key to successfully addressing research challenges around optimising battery performance, enhancing capacity, maximising power delivery, and minimising degradation lies in improved understanding of the materials on the nanoscale. Variations in chemistry, grain size and texture are related to the performance and stability of the final battery; being able to characterise the material is vital for ensuring the quality of the final product.

Many of the battery materials are beam sensitive, making analysis in SEM challenging. The latest technology used in the Oxford Instruments Symmetry S2 (EBSD) and Ultim Max (EDS) detectors has improved the sensitivity significantly, thereby providing a solution for characterisation of beam sensitive materials.

From Mine to Manufacture

Li-ion batteries have been a key enabling technology over the last decade and are vital to further developments of EVs (Electrical Vehicles). Controlling the cleanliness of the raw materials is critical for ensuring the safety of the batteries. Automated analysis makes it fast and easy to identify contaminants and where the contaminants are being introduced.

NCM cathode material characterised using EBSD

Discover how EBSD can be used to obtain grain size and texture information from NCM (nickel, cobalt, manganese) cathode material. By characterising and comparing samples of different cathode materials at different stages of the battery’s lifetime, it's possible to link the performance with the microstructure and improve understanding of how the materials can be optimised.

Identifying contaminants in Li-Ion battery production using AZtecFeature

Lithium Ion batteries are found in most mobile electronic devices (e.g. laptop computers, phones etc). They are the dominant battery technology due to their superior energy to weight ratio and lack of memory effect. They are also the primary battery type used in the latest generation of electric and hybrid cars.
