September 24, 2021: Gel battery maker Gelion Technologies has teamed up with the Australian gel lead-acid battery firm Battery Energy Power to develop Gelion’s zinc bromide batteries in Fairfield, Sydney, the firms confirmed on September 8.

Gelion’s zinc batteries were designed by the University of Sydney, and the companies’ partnership will quicken the road to commercialization for Gelion, which will make use of Battery Energy Power’s existing distribution networks in Australia and New Zealand.

Gelion will also use Battery Energy Power’s manufacturing facilities, and full testing will be carried out next year with a view to deployment in the first quarter of 2023.

Because both firms’ technologies have similarities it means the equipment will not have to be completely overhauled to make the new products.

Gelion says its zinc bromide batteries are not flow batteries but use a gel chemistry to replace the liquid bromine, simplifying the design to make a more robust product that is cheaper to make and maintain.

“The zinc bromide chemistry can operate in high-temperature environments without the need for cooling, making it perfect for Australia’s climate,” the company says.

“The chemistry also allows the battery to be fully discharged with no harm to performance. This battery is designed to last up to 5,000 cycles with a 100% depth of discharge.”

Battery Energy Power makes a range of products including lithium-ion and lead-acid batteries and energy storage systems for applications including grid solar, critical power, standby backup and railway rolling stock.
