NEO Battery Materials announces new silicon battery performance benchmarks

The best-manufactured samples have demonstrated over a 70% increase in cycle life improvement compared to the previous best batch.
TORONTO — NEO Battery Materials Ltd., a silicon anode materials developer that reportedly enables longer-running, rapid-charging lithium-ion batteries, announces new testing results in silicon battery performance from NEO’s improved uniform nanocoating product.
As announced on April 18, 2023, NEO achieved a significant manufacturing improvement of uniformly nanocoating silicon with strong polymer layers. This milestone helped extend the battery cycle life or capacity retention by effectively controlling the silicon’s volume expansion problem. Before this innovation, non-uniform coatings led to mechanical breakdowns, resulting in inadequate performance of silicon batteries.
Over the past months, the R&D engineering team further optimized the uniform nanocoating capability with chemical additives and rigorously performed battery charge/discharge (cycling) tests. Several iterations have successfully validated the performance enhancement from robust uniform nanocoating, proving a substantial difference in cycle life/capacity retention between non-uniformly and uniformly nanocoated silicon anodes. The best-manufactured samples have demonstrated over a 70% increase in cycle life improvement compared to the previous best batch.
Dr. S. G. Kim, CTO of NEO, commented, “NEO’s uniform nanocoating technology used to produce silicon anodes significantly improves the battery performance by overcoming the critical volume expansion problem. For the improved uniform coating, no equipment or process modifications are required, but this was solely achieved by chemical additives: this maintains our ability to manufacture products at reduced costs of more than 70% compared to competitors.”
The Company also announces that the Korean Intellectual Property Office (KIPO) has duly registered the trademark application for NEO’s silicon anode material, NBMSiDE®. After waiting for 18 months for approval, in accordance with the Trademark Act, a trademark has been registered at the KIPO under the classes of active negative polar substances for secondary cell batteries.
