ITRI and eJoule Inc. have entered a partnership to develop advanced nickel-based battery technology for electric vehicles and home energy storage. This collaboration combines new cathode manufacturing processes with cell engineering to improve battery longevity.
Why it matters
The development aims to create batteries with higher energy density and a longer cycle life, which could eventually lower costs and improve performance for household electric vehicle owners and energy storage users.
Testing of the new single-crystal cathode active materials shows stable performance after repeated charge-discharge cycles. The technology is specifically designed to eliminate the conventional precursor stage during manufacturing to streamline production.
The players
ITRI
A Taiwan-based research and development institution focused on industrial technology and advanced engineering solutions.
eJoule Inc.
A California-based company that specializes in cathode materials and advanced battery manufacturing processes.
The details
eJoule provides single-crystal cathode materials created through its proprietary Dynamic Crystallization Process, which skips the traditional precursor phase. ITRI then applies its expertise in electrode fabrication and cell design to integrate these materials into finished batteries. By optimizing the specific cell capacity and structural specifications, the team aims to bridge the gap between initial laboratory research and large-scale commercial battery production.
