Exceptional Structural Durability of NEO Battery's 100% Silicon Anodes for Next-Generation Flexible Battery Applications

Vancouver, May 11, 2021 - Dr. Jong Hyeok Park, Director and Chair of Scientific Advisory Board of NEO Battery Materials Ltd. (TSXV: NBM) ("NEO" or the "Company"), is pleased to announce that NEO's silicon (Si) anode succeeded to achieve exceptional flexibility and durability from a continuous bending test.

A 3.5 x 9.5 cm² sized pouch flexible battery cell with multi-electrodes stack was assembled at an industrial facility to investigate mechanical durability against bending fatigue. After undergoing 30,000 bending cycles (bending radius: 25 mm), conventional Si anodes showed serious cracks and deformation, as some fragments had been detached from the copper (Cu) foil. However, there were no perceptible degradation in the NEO's Si anodes after the same bending test, displaying the required robustness to effectively counter the volume expansion problem.

Flexible batteries are being recognized as a forefront technology in the rise of next-generation, rechargeable batteries. An integration of a flexibility characteristic allows the lithium-ion battery (LIBs) to be safe and lightweight, retain a higher rate capability, and possess a greater energy and power density compared to current rigid LIBs.
