NEO Battery Supplies Ltd. (“NEO” or the “Firm”) (TSXV: NBM) (OTC: NBMFF), a low-cost silicon anode supplies developer that permits longer-running, rapid-charging lithium-ion batteries, is happy to introduce NBMSiDE^® P-300N, a complicated silicon anode product with the very best capability retention achieved thus far. The P-300N is a mass-producible prototype optimized to reinforce battery stability whereas sustaining low-cost manufacturing.

P-300N Silicon Anode: Highest Capability Retention Achieved to Date

Constructing on the inspiration of the P-300 silicon anode launched in January, NBMSiDE^® P-300N is the Firm’s newest engineering feat with the very best capability retention achieved thus far. NEO’s R&D efficiently refined the synthesis course of and materials traits whereas sustaining low prices and minimizing preliminary capability loss.

NEO’s precedence is optimizing the 50-cycle common Coulombic Effectivity¹ (CE) on the half cell² utilizing a 100% pure silicon anode. With this rigorous testing situation³, a excessive CE over the primary 50 cycles is strictly required for and determines excessive capability retention in lengthy battery efficiency exams of 300+, 500+, and 1,000+ cycles.

In comparison with predecessors, the P-300N has recorded the very best 50-cycle common CE of over 99.8%. Furthermore, because of the flexibility of NEO’s synthesis methodology, two P-300N variations have been produced to cater to totally different business wants:

• Excessive-Capability Variant: Demonstrates preliminary capability over 2,000 mAh/g with a median CE of over 99.5% and sustaining efficiency with 50+ cycles
• Excessive–Stability Variant: Offers a steadiness of cycle efficiency and capability with a median CE of over 99.8% with roughly 2,000 mAh/g in preliminary capability

P-300N is positioned as a low-cost, aggressive answer for broad functions, together with 1) electronics, energy instruments, or drone/UAV⁴ that require excessive capability with ultra-fast charging/discharging and a pair of) EV and power storage that require excessive capability with long-term stability.

Subsequent Steps: Full Cell Testing & Scaling Up for Commercialization

Resulting from surpassing half cell outcomes, NEO is present process long-term full cell⁵ exams of 300+ cycles with the P-300N. With varied cathode chemistries, P-300N is mixed with graphite to kind high-capacity silicon-graphite anodes⁶. Excessive capability retention has been realized, however as soon as all inner targets are achieved, the Firm will announce technical outcomes via a subsequent information launch.

With scale-up efforts initiated as of February, the P-300N would be the primary product for mass-producibility testing. A key benefit of the P-300N is its adaptability to mass manufacturing with out modifying present processing tools. After finishing small-scale optimization, NEO plans to fabricate near-commercial battery cells with 3 to five Ah capacities with world battery worth chain gamers.

P-300N: Technical Particulars of Optimization

The upgraded P-300N incorporates key refinements in particle dimension distribution, form management, and composite layer coating on the silicon particle. The composite layer coating provides enhanced safety towards the direct contact of the silicon anode and electrolyte, mitigating capability loss and bettering biking life. Moreover, a strengthened polymer coating community aids in mechanical stress dissipation with out compromising conductivity between silicon particle constructions.

¹Coulombic Effectivity (CE): Ratio of electrons transferred out from an electrode materials/battery throughout discharging to the quantity transferred into the fabric throughout charging over a full charging cycle (Discharging Capability-to-Charging Capability). Ex. If the present discharging capability is 2,000 mAh/g and the previous charging capability was 2,500 mAh/g, the Coulombic effectivity is 80%.

²Half Cell/⁵Full Cell: Lithium-ion battery includes all 4 core supplies (cathode, anode, separator, and electrolyte). Typically, battery anode supplies proof-of-concept and optimization are accomplished with half cells. Solely the anode, separator, and electrolyte are used with a lithium-metal counter electrode that will provide infinite lithium ions. Full cells have a restricted variety of lithium-ions, on condition that commercial-level cathode supplies retain a restricted provide of lithium ions in comparison with lithium-metal. Consequently, capability retention is closely affected by Coulombic effectivity at each charging cycle.

³Lithium-ion battery anode supplies are both comprised solely of graphite or hint quantities of silicon (roughly 2 to 10%) with graphite. With out graphite, an unprocessed 100% silicon anode’s capability degrades quickly as a result of silicon’s quantity growth. Even when a processed silicon anode is used, the technical and price boundaries preclude the commercialization of a 100% pure silicon anode. Due to this fact, the business acknowledges {that a} 100% pure silicon anode testing situation is without doubt one of the most technologically rigorous and difficult circumstances for battery testing.

⁴UAV: Unmanned Aerial Car

⁶Silicon-Graphite Anode: For commercial-level lithium-ion battery anodes, silicon anodes can not wholly change graphite anodes. Therefore for sure batteries, silicon anodes and graphite anodes are combined to kind a blended anode known as silicon-graphite anodes. On common, silicon anodes comprise roughly 5 to 10% of the anode materials.
