Advanced silicon anode battery retains 90% power after 300 cycles

NEO Battery Materials, a Canadian company, has developed an advanced silicon anode battery, the P-300N, which retains over 90% of its capacity after 300 full charge-discharge cycles, surpassing its initial target of 80%. This achievement positions the P-300N as one of the most stable and cost-effective battery materials globally, particularly for electric vehicle (EV) applications aiming for a 1,000-mile range. The battery uses metallurgical-grade silicon (MG-Si) as its core anode material, which is significantly cheaper than graphite and offers manufacturing advantages over other silicon sources, enabling scalable and cost-efficient production of high-energy-density batteries. The P-300N’s performance was validated in full coin cell tests that simulate commercial lithium-ion battery behavior more realistically than traditional half-cell tests. NEO’s proprietary processing addresses silicon’s typical challenges, such as volume expansion and particle pulverization, thereby enhancing cycle life without sacrificing energy density or safety. Following these promising results
