Nano hollow spherical silicon cycling test
Cycling Test
N/P = 1.12, pouch cell capacity: 2.2 Ah
Matching Formula
Si/C anode material : CMC : PAA-Li : S-BR : SP : SWCNT = 94.4 : 1 : 2 : 1.5 : 1 : 0.1
The powder shows excellent process ability, with uniform slurry mixing, no gas generation, and no cracking during calendering.
After 200 cycles, the capacity retention remains above 99%, with an average capacity decay of less than 0.01% per cycle.
