For marking a development in electric vehicle (EV) technology, Panasonic Energy, has sealed an agreement with Sila Nanotechnologies to procure an innovative nano-composite silicon anode material for EV lithium-ion batteries. This strategic partnership signifies a pivotal step in advancing EV battery performance.
Material for Future-Ready EV Batteries
Sila Nanotechnologies, based in Alameda County, California, is set to supply Titan SiliconTM to Panasonic Energy. This high-performance silicon anode material boasts superior capabilities compared to traditional silicon. It offers increased battery capacity and addresses the critical issue of expansion during charging- a major setback for traditional silicon anodes.
Unlocking Potential with Silicon
Silicon, known for its theoretical capacity that is tenfold that of graphite, the commonly used anode material in current lithium-ion batteries, holds the key to enhancing battery performance. However, its tendency to expand during charging and subsequent impact on battery life has been a major challenge. Through its collaboration with Sila, Panasonic Energy aims to overcome these hurdles by replacing a significant portion of graphite with silicon in the anode, thereby improving the energy density of batteries.
Panasonic Energy’s Ambitious Goals
With a history of pioneering in battery technology, Panasonic Energy has already achieved success in mass-producing the industry’s first silicon-based EV batteries. The company now targets a 25% increase in battery energy density, aiming to reach 1,000Wh/L by 2031. The integration of next-generation silicon materials into its battery development is crucial to achieving this goal.
Strengthening Local Supply Chains
The required silicon material will be sourced from Sila’s manufacturing facility in Washington State, U.S. Panasonic Energy is focusing on North America to bolster local supply chains and expand battery production. This partnership is not only strategically beneficial for Panasonic Energy’s supply chain resilience but is also expected to reduce the company’s carbon footprint, and logistics and transportation costs.
Expanding Partnerships
Panasonic Energy, through additional partnerships in the region, plans to broaden its silicon procurement network. With its advanced battery technology and expertise, the company is poised to significantly contribute to the growth of the lithium-ion battery industry. The increased demand for EVs worldwide is a catalyst for Panasonic Energy’s efforts, aligning with its commitment to fostering a more sustainable society.
