Lithium-Ion

Performance Enhancement of Nanosilicon Anodes via Boron Doping B-doping lowers the expansion of the silicon nanoparticle and improves its electronic conductivity. Surface B-dipoles coordinate with Li2CO3 to create a physical barrier against electrolyte improving passivation.

SILICONBORON PARTICLE MORPHOLOGY AND DISTRIBUTION

CYCLING CAPACITY RETENTION VS BCONTENT

Boron doped nanosilicon coated with lithium carbonate improves cycle and calendar lifetimes of silicon through enhanced mechanical stability as well as unique chemical stability afforded by B-dipole formation at particle surface.
