Li-ion Battery Components

Lithium-ion (Li-ion) batteries are an advanced battery technology which have four major components: anode, cathode, separator, and electrolyte.

At Micromeritics we have instrumentation for all stages of battery production starting from the raw material precursors to the final battery cell.

In the future the liquid electrolyte may be replaced by a solid electrolyte for improved safety and performance.
