UltraCharge raising AUD2.5m ‘to accelerate Li-ion tech’

Australia-headquartered lithium and flow battery developer UltraCharge has told BBB it is finalising a raise of AUD2.5 million ($1.9m) to boost battery tech investments.

UltraCharge CEO Kobi Ben-Shabat (pictured) said the cash would be used in part to expand development of titanium dioxide (TiO2) as an alternative to graphite in the anodes of lithium-ion batteries, in a bid to improve fast charging capabilities, lifespan and safety.

Thin foils from Dexmet

Dexmet has introduced new microgrid anode and cathode foil materials down to 25 micron (.001”) in both aluminum and copper at widths up to 305mm (12”). 

These thinner materials produce very small openings in the material, and should prove to be the perfect anode and cathode electrode solution for improved overall cell performance.
