Amara Raja Batteries Limited and Gridtential Energy have recently collaborated for Silicon Joule bipolar technology that revolves around advanced lead batteries with silicon at core. The statement says that the said tech is design-driven, low-cost, high-performance, patented energy storage solution that offers improved power density along with better cycle life, dynamic charge acceptance and a wider temperature range. Moreover, the batteries will have up to 40% lower weight while retaining full lead-battery recyclability.
