Summary Impurities and contaminants in the material used in the production of Li-ion batteries can have catastrophic impacts on the finished products. As such, monitoring of the quality and cleanliness of materials throughout the production process is essential if contaminants are to be found and their sources controlled. This monitoring must start with the raw materials produced at the mine and continue through to the final battery grade powders. This application note demonstrates a scanning electron microscopy (SEM) based solution for automatic detection and identification of impurities in battery raw material powders. By taking samples at different steps of the production process it is possible to identify where contaminants are introduced; thereby allowing sources to be identified and solutions developed.

Summary

Impurities and contaminants in the material used in the production of Li-ion batteries can have

catastrophic impacts on the finished products. As such, monitoring of the quality and cleanliness of

materials throughout the production process is essential if contaminants are to be found and their

sources controlled. This monitoring must start with the raw materials produced at the mine and

continue through to the final battery grade powders.

This application note demonstrates a scanning electron microscopy (SEM) based solution for

automatic detection and identification of impurities in battery raw material powders. By taking

samples at different steps of the production process it is possible to identify where contaminants are

introduced; thereby allowing sources to be identified and solutions developed.
