Binder-less tin phosphide/carbon composite film electrodes for lithium-ion batteries, fabricated by aerosol deposition process
Researchers at the Toyohashi University of Technology have successfully fabricated a binder-less tin phosphide (Sn4P3)/carbon (C) composite film electrode for lithium-ion batteries via aerosol deposition. The Sn4P3/C particles were directly solidified on a metal substrate via impact consolidation, without applying a binder. Charging and discharging cycling stabilities were improved by both complexed carbon and controlled electrical potential window for lithium extraction. This finding could help realize advanced lithium-ion batteries of higher capacity.
