, the JAIST team reported a holistic approach to synthesizing novel and highly resilient SiMPs consisting of black glasses grafted“Silicon nanoparticles might provide increased effective surface area but that comes with its own drawbacks like increased consumption of electrolyte as well as poor initial coulombic efficiency after a few cycles of charging and discharging,” research lead Noriyoshi Matsumi said in a media statement.
The screening showed that the material has great lithium diffusion ability and reduced internal resistance and overall volumetric expansion. It also showed a 99.4% retention of energy capacity even after 775 cycles of charging and discharging. In addition to this, the material exhibited great mechanical stability throughout the testing process.
