AAA size alkaline battery with selective focus on single battery

Free resources to help the chemist improve battery performance

In collaboration with Waters Corporation and Oxford Instruments, Chemistry World has compiled a collection of application notes and white papers that provide expert knowledge of factors that affect lithium-ion battery performance.

We consider a scanning electron microscope (SEM) based solution for the automatic detection and identification of impurities in battery raw material powders, which helps to identify and solve the problems that impurities cause in end products.

The optimization of the cathode material is of central interest for the current generation of lithium-ion battery technologies, as even small changes to the cathode can have a major impact on the battery. We demonstrate how it is possible to link the ongoing performance of the cathode material to the microstructure by extracting grain size and texture information from NCM cathode material (nickel, cobalt, manganese) using electron backscattering.

Ultimately, to improve overall performance, all aspects of the battery device must be understood and optimized. Atomic Force Microscopes (AFMs) provide a way to visualize battery materials at micro- and nanometer resolutions to assess their texture and morphology – for example, to better understand how their processing can affect performance. We share examples of how AFMs can be used to evaluate materials from different parts of the battery cell to provide critical information to improve their overall performance.
