Battery Manufacturing: What You Need to Know

Electric vehicles (EVs) play a crucial part in attaining a carbon-neutral future, and the need for automotive batteries to increase significantly.

FREMONT, CA: Stationary storage batteries (for residential, industrial, and grid usage) are to utilize in many applications, with a projected 47-fold increase. The manufacturing and disposal processes contain dangers, such as the emission of vast quantities of greenhouse gases (GHG) and the use and disposal of enormous amounts of resources as needs increase. There is an urgent need to enhance storage batteries' performance and manufacturing and expand battery recycling techniques to mitigate these hazards. Development of storage battery manufacturing and recycling through a vast array of measurement and analysis technologies and engineering, from R&D of battery materials. The performance evaluation, production management, and support for the development of electric vehicles to recycling, from particles to the vehicle, then back to particles.

Material evaluation, evaluation of the film deposition process, and quality control: For achieving higher quality and performance in the research and development of lithium-ion batteries, which are becoming more prevalent in a variety of fields, and all-solid-state batteries, which become the next generation of batteries, new analysis, and evaluation technologies get required. It provides various analysis and measurement solutions for battery materials R&D and performance evaluation. Different battery performance evaluations are conceivable, from small (single cell) to big (battery modules/battery packs).

Management of safety during manufacturing and testing: All-solid-state batteries management of solid electrolytes for safety gets leveraged in manufacturing. Solid-state batteries are projected to be employed in power supplies for autos and other applications because they do not include combustible electrolytes. Particularly, sulfide-type all-solid-state batteries are attracting attention due to their excellent material properties, such as high lithium-ion conductivity and wide operating temperature range. Electrolyte tends to produce hydrogen sulfide (H2S) gas due to a hydrolysis reaction with a small amount of water, necessitating adequate safety precautions.

Detection of fumes produced by a malfunctioning battery: Several safety tests on lithium-ion batteries get performed. In the automotive development phase, for instance, they help with safety evaluation by determining if CO gas created during the nail penetration test of car lithium-ion batteries enters the vehicle. In addition, gas concentrations such as CO and CO2 can get detected in real-time during battery development heating tests.
