Abstract
Nanoporous carbon coated lithium vanadium fluorophosphate materials and cathodes for fast charging li-ion batteries are described. Formation of the materials using polymer-templating is also described.
Claims12
A cathode material for lithium ion batteries, the cathode material comprising:
- carbon coated nanoporous lithium vanadium fluorophosphate (c-nLVPF) having a templated pore structure;
- wherein the cathode material is synthesized using a combination of a fluoropolymer and polymethyl methacrylate (PMMA) colloids that provide a fluorine source, an oxygen scavenger, and a template material for forming the pore structure in the cathode material.
A cathode material for lithium ion batteries, the cathode material comprising:
- carbon coated nanoporous lithium vanadium fluorophosphate (c-nLVPF) having a substantially uniform pore structure;
- wherein the cathode material is synthesized using a combination of a fluoropolymer and polymethyl methacrylate (PMMA) colloids that provide a fluorine source, an oxygen scavenger, and a template material for forming the pore structure in the cathode material.
