By supporting silicon anodes, G-LEAF helps manage large volume strains during cycles. This ensures long-term electrical connectivity and stability, with consistent performance over 300 cycles at 1 A/g, maintaining over 1000 mAh/g in capacity.
The high specific capacity of G-LEAF (>3000 mAh/g) accelerates electron flow, allowing for significantly faster charging times without compromising efficiency or safety, effectively reducing downtime in battery-powered devices.
G-LEAF’S exceptional electrical conductivity enhances energy storage capacity. With a +30% improvement in cyclability, as certified by VARTA, G-LEAF raises energy density standards, resulting in longer-lasting, more powerful batteries.
G-LEAF’s role in extending battery life aligns with sustainable technology goals. The reduction in frequent battery replacements decreases resource consumption, contributing to a greener future.
