Talga Technologies Li-ion battery anode product, Talnode-C, outperforms existing lithium battery technology in cold weather situations. This is great news for the clean tech sector as charging at low temperatures has been a problem.

“Talga Technologies, the advanced materials technology company listed on the Australian Stock Exchange company, is scaling up its R&D operations at the Bradfield Centre on Cambridge Science Park.
The move comes as tests show that Talga’s Li-ion battery anode product, Talnode-C, outperforms existing lithium battery technology in cold weather situations, where lithium products have traditionally struggled.
“We make graphene and graphite materials,” says Talga Resources R&D manager, Sai Shivareddy. “Graphene is made by an electrochemical exfoliation process in an aqueous electrolyte – water plus salt – by using our natural graphite rocks in electrodes.”
“We are targeting exponential growth in battery making facilities in Europe,” Dr Shivareddy says. “Being in Sweden gives us security of supply. If 30 per cent of vehicles in Europe were electric, you’d need three million tons of graphite and at the moment Europe makes not even one per cent of that. Big resources are needed to make the shift to a sustainable low carbon economy, and we take clean technology very seriously.”
Talga’s technology also solves a long-running issue – charging at low temperatures.
“We’ve solved the issue of charging at low temperatures,” says Sai. Talnode-C retains 100 per cent capacity and 100 per cent cycle efficiency at 0°C, outperforming current commercial products in tests at a leading independent battery institute in Japan. Talga’s high-energy battery anode products also offer 70 per cent more density than graphite-only anodes, adding further performance gains.
Significant resources to develop the cleantech sector are now starting to gear up in Cambridge. Jeanette Walker, director of the Science Park, is developing a cleantech model which will work along the lines of the shared-resources model that works so well in the life sciences sector.”
