July 2, 2020: Gridtential, the bipolar battery developer, is working with LOLC Advanced Technologies on prototyping lead batteries using both Gridtential’s silicon joule plates and adding graphene, a battery additive, to active materials, the companies announced on June 23.
The graphene additive — AltaLABGX — will be supplied by Ceylon Graphene Technologies, a joint venture set up between LOLC and the Sri Lanka Institute of Nanotechnology.
“Preliminary work indicates that the combination of these elements will lead to higher performing batteries in energy density, charging rates and cycle life,” said Gridtential.
Gridtential, which won the 2018 BCI Sally Breidegam Miksiewicz Innovation award for its silicon joule technology, has several big names invested in its work, including Crown Battery, East Penn, Power-Sonic and Leoch.
This June, Indian battery giant Amara Raja announced it had a technology evaluation agreement with the firm.
Graphene has become a widespread additive in both lead and lithium batteries, having been found to increase capacity and lifecycle.
