The cathode materials of lithium batteries are generally divided into the following categories:
The first is a carbon-negative material:
At present, the anode materials actually used in lithium ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, pyrolytic resin carbon, etc.
The second is a tin-based cathode material:
Tin - based anode materials can be divided into tin oxides and tin - based composite oxides.An oxide is an oxide of a variety of valence metals tin.There are no commercial products at present.
The third is a lithium transition metal nitride cathode material, there is no commercial product.
The fourth type is an alloy-type anode material:
These include tin-based, silica-based, germany-based, aluminium-based, antimony-based, magnesium-based and other alloys. There are currently no commercial products.
The fifth is nano - cathode materials: carbon nanotubes, nano - alloy materials.
The sixth kind of nanomaterial is nanometer oxide material
