Abstract
The disclosure relates to a carbon-based electrode material that has been graphitized to hold ions in the electrode of a battery and more particularly include carbide or carbide and nitride surfaces that protect the graphite core. The preferred batteries include metal ion such as lithium ion batteries where the carbon-based electrode is the anode although the carbon-based electrode may also serve in dual ion batteries where both electrodes may comprise the graphitized carbon-based electrodes. The electrodes are more amorphous than conventional graphite electrodes and include a carbide or nitride containing surface treatment.
Claims13
A lithium-ion battery comprising:
- a cathode;
- an anode;
- and
- an electrolyte;
- wherein the anode comprises particles with a surface comprising at least one carbide compound and a core comprising graphite
- wherein the carbide compound includes a carbide forming element of B and Ce.
