SM-Silicon/3590™ Silicon Anode Material
Gradual Activation Chemistry (GAC)
Gradual Activation Chemistry (GAC) begins to work immediately after the first cycle and increases capacity for the first 95-125 cycles with a fade rate of 0.00%. This acts to regain capacity lost in formation. Only after 95-125 cycles does fading begin, but it is a gradual fade.
Coulombic Efficiency
As the graph shows, the SM-Silicon/3590™ has excellent Coulombic Efficiency (CE), which is nearly 100% over long cycling. This can not be achieved without a very stable SEI. As the SEI increases in thickness or is not stable, the cell will not cycle and the CE will not be so high.
High Capacity and Cycle Stability
Capacity remains above 80% for greater than 300% longer than other known silicon materials. This performance was reproduced with various binders of which we do not use any special additives.
