Description

General description

We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Aluminum oxide serves as a multifunctional additive or coating in lithium-ion batteries, helping stabilize electrode–electrolyte interfaces, suppress side reactions, improve thermal stability, and extend cycle life. By enabling safer, longer-lasting cells, it reduces material waste and energy use across the battery lifecycle. Click here for more information.

Application

Owing to its high hardness, chemical stability and thermal conductivity, alumina finds applications as filler for metals and plastics. It also finds applications in paints, polisher and cosmetics.
