Problem
Current lithium‑ion batteries rely on graphite anodes, which limit energy density, charging speed, and performance in low‑temperature environments. Additionally, the supply chain for graphite is vulnerable to geopolitical constraints, creating security risks for manufacturers.
Solution
GDI produces patented 100 % silicon anodes that replace graphite in lithium‑ion cells, delivering roughly 30 % higher energy density, three times faster charging, and improved cold‑temperature performance. The anodes feature a continuous, flexible silicon layer that accommodates volume expansion during charge cycles, eliminating the mechanical stress that plagues other silicon designs. GDI’s AGC PlasmaMAX™ deposition process accelerates silicon coating by 5–10×, enabling seamless integration into existing high‑volume battery production lines without major equipment changes. This technology provides manufacturers across defense, drones, medical devices, e‑mobility, and aerospace with a scalable path to higher‑performance, lighter batteries while reducing reliance on graphite supplies.
Target Audience
Primary customers are battery manufacturers and product developers in defense, unmanned aerial systems, medical technology, electric vehicles, and aerospace seeking higher energy density, rapid charging, and supply‑chain resilience.
