Protective coating for Li-ion batteries

The challenge

The performance and lifetime of Li-ion batteries are hampered by corrosion of the electrodes by side-reactions between the electrode and electrolyte.

The customer

A leading Li-ion battery manufacturer

Beneq solution

An ultra-thin ALD protective coating was applied to reduce the side-reactions. This significantly reduced the fading of battery capacity caused by repeated charge and unload cycles.
