NEO Battery Materials Ltd. (“NEO” or the “Company”) (TSXV: NBM) (OTC: NBMFF), a low-cost silicon anode materials developer that enables longer-running, rapid-charging lithium-ion batteries, is pleased to introduce NBMSiDE® P-300N, an advanced silicon anode product with the highest capacity retention achieved to date. The P-300N is a mass-producible prototype optimized to enhance battery stability while maintaining low-cost production.
P-300N Silicon Anode: Highest Capacity Retention Achieved to Date
Building on the foundation of the P-300 silicon anode introduced in January, NBMSiDE® P-300N is the Company’s latest engineering feat with the highest capacity retention achieved to date. NEO’s R&D successfully refined the synthesis process and material characteristics while maintaining low costs and minimizing initial capacity loss.
NEO’s priority is optimizing the 50-cycle average Coulombic Efficiency1 (CE) on the half cell2 using a
Compared to predecessors, the P-300N has recorded the highest 50-cycle average CE of over
- High-Capacity Variant: Demonstrates initial capacity over 2,000 mAh/g with an average CE of over
99.5% and maintaining performance with 50+ cycles - High-Stability Variant: Provides a balance of cycle performance and capacity with an average CE of over
99.8% with approximately 2,000 mAh/g in initial capacity
P-300N is positioned as a low-cost, competitive solution for wide applications, including 1) electronics, power tools, or drone/UAV4 that require high capacity with ultra-fast charging/discharging and 2) EV and energy storage that require high capacity with long-term stability.
Next Steps: Full Cell Testing & Scaling Up for Commercialization
Due to surpassing half cell results, NEO is undergoing long-term full cell5 tests of 300+ cycles with the P-300N. With various cathode chemistries, P-300N is combined with graphite to form high-capacity silicon-graphite anodes6. High capacity retention has been realized, but once all internal targets are achieved, the Company will announce technical results through a subsequent news release.
With scale-up efforts initiated as of February, the P-300N will be the main product for mass-producibility testing. A key advantage of the P-300N is its adaptability to mass production without modifying existing processing equipment. After completing small-scale optimization, NEO plans to manufacture near-commercial battery cells with 3 to 5 Ah capacities with global battery value chain players.
P-300N: Technical Details of Optimization
The upgraded P-300N incorporates key refinements in particle size distribution, shape control, and composite layer coating on the silicon particle. The composite layer coating offers enhanced protection against the direct contact of the silicon anode and electrolyte, mitigating capacity loss and improving cycling life. Additionally, a reinforced polymer coating network aids in mechanical stress dissipation without compromising conductivity between silicon particle structures.
1Coulombic Efficiency (CE): Ratio of electrons transferred out from an electrode material/battery during discharging to the number transferred into the material during charging over a full charging cycle (Discharging Capacity-to-Charging Capacity). Ex. If the current discharging capacity is 2,000 mAh/g and the preceding charging capacity was 2,500 mAh/g, the Coulombic efficiency is
2Half Cell/5Full Cell: Lithium-ion battery comprises all four core materials (cathode, anode, separator, and electrolyte). Generally, battery anode materials proof-of-concept and optimization are completed with half cells. Only the anode, separator, and electrolyte are used with a lithium-metal counter electrode that may supply infinite lithium ions. Full cells have a limited number of lithium-ions, given that commercial-level cathode materials retain a limited supply of lithium ions compared to lithium-metal. Consequently, capacity retention is heavily affected by Coulombic efficiency at every charging cycle.
3Lithium-ion battery anode materials are either comprised solely of graphite or trace amounts of silicon (approximately 2 to
4UAV: Unmanned Aerial Vehicle
6Silicon-Graphite Anode: For commercial-level lithium-ion battery anodes, silicon anodes cannot wholly replace graphite anodes. Hence for certain batteries, silicon anodes and graphite anodes are mixed to form a blended anode called silicon-graphite anodes. On average, silicon anodes comprise approximately 5 to
