NEO Battery Materials Ltd. (“NEO” or the “Company”), a low-cost silicon anode materials developer that enables longer-running, rapid-charging lithium-ion batteries, is pleased to announce exceptional testing results in silicon battery performance from NEO’s improved uniform nanocoating innovation.

As announced on April 18, 2023, NEO achieved a significant manufacturing innovation 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.”

Mr. Spencer Huh, President & CEO of NEO, added, “We are excited about the success of our uniform coating test results – a key milestone in the validation of our high-performance silicon anode materials. I am proud of our highly experienced R&D team in this achievement as it underpins our capacity that both supports commercialization and solidifies our work towards advanced agreements in the EV battery supply chain. Most recently, we have secured top battery professionals that include 2 PhDs and 3 Masters, and this addition of qualified researchers will give us the next leg-up to achieve our milestones.”
