CalBattery Developing Advanced and Low-Cost Lithium-Ion Battery
They plan to achieve this with the use of a silicon-graphene anode, which reportedly greatly increases the energy density of the battery, and it is based on the company’s third generation silicon-graphene material. Some independent tests have already been performed, and have apparently confirmed that the CalBattery cells can hold 525 watt-hours/kg, whereas conventional batteries only manage between 100 and 180 watt-hours/kg.
Anode capacity is also greatly increased, reaching 1,250 mili-amp-hours/gram, while regular lithium-ion cells only manage to achieve somewhere in the region of 325 mili-amp-hours/gram. This all equates to a storage capacity which is three times larger than normal, or as CalBattery put it: “more than a 300 percent improvement in lithium-ion battery capacity, and an estimated 70 percent reduction in lifetime cost for batteries used in consumer electronics, EVs, and grid-scale energy storage."
