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.
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.
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.
