Battery electrolyte developer Ampcera has announced the latest step in the commercialisation of its flexible solid electrolyte (SE) membrane technology for solid-state lithium-ion batteries.
The US firm claims its solid-state electrolyte (SSE) has the potential to enable solid-state lithium metal batteries to achieve an energy density of 500Wh/kg while reducing cost to below $100/kWh.
Ampcera has started testing 200 mAh pouch cells using its solid electrolyte membranes, which is based on ceramic/polymer composite materials.
Its goal is to accelerate the commercialisation of its technology and achieve 400-500Wh/kg energy density in the next 3-5 years on a commercial scale.
The SE membranes are 25 microns thick, have a room temperature lithium ionic conductivity >1 mS/cm, and are stable against a lithium metal anode, say the company.
Ampcera has filed multiple US patent applications and an international PCT patent application on its flexible SE membranes, a low-cost manufacturing method, and the corresponding SSBs.
The company says its vertically integrated manufacturing from materials synthesis to battery cell assembly reduces the cost of SSBs to below $100 per kilowatt hour— the holy grail of electric vehicle OEMs
The company is expanding its team to scale up the technology and further integrate its solid-state lithium battery cells as it commits to accelerating to commercialising the technology in the coming years, said Dr. Hui Du, co-founder and CTO of Ampcera.
