Lithium Si-Graphene battery anode

I haven't found this discussed on ecomodder, it seems to be a month-old news:
Quote:
The work is showing extraordinary results. Independent full cell tests reveal unrivaled performance characteristics, with an energy density of 525WH/Kg and specific anode capacity 1,250mAh/g. In contrast, most commercial LIBs have an energy density of between 100-180WH/kg and a specific anode capacity of 325mAh/g. “This equates to more than a 300% improvement in LIB capacity and an estimated 70% reduction in lifetime cost for batteries used in consumer electronics, EVs, and grid-scale energy storage,” said CalBattery CEO Phil Roberts.
