Voltavate

Its nanofiber separator is applied directly onto electrodes on site and is designed to fit existing battery production lines without changes, which the company says raises production speed and cuts cell assembly scrap. Voltavate also offers customizable separators for lithium-sulfur, sodium-ion and other emerging chemistries, for electric vehicle, grid storage and portable electronics batteries.

Voltavate is based in Melbourne, Australia. The Australian Renewable Energy Agency backs its manufacturing-integrated separator approach through a $3.55 million pilot-scale program.
