What factors should be considered in the selection of lithium battery anode and cathode materials?

The choice of cathode materials for lithium batteries is important based on the following considerations: 1) It has a higher oxidation-reduction reaction potential, so that the lithium battery can reach a higher output voltage; 2) The content of lithium is high, and the material density is high, which makes the lithium battery have Higher energy density; 3) The structural stability during the chemical reaction process should be good, so that the lithium battery has a long cycle life; 4) The electrical conductivity should be high, so that the lithium battery has good charge and discharge rate performance; 5) Chemical stability and The thermal stability is good, and it is not easy to decompose and generate heat, so that the lithium battery has good safety; the selection of the anode material of the lithium battery should consider the following conditions: 1) It should be a layered or tunnel structure to facilitate the deintercalation of lithium ions; 2) There is no structural change during the deintercalation of lithium ions, with good charge-discharge reversibility and cycle life; 3) Lithium ions should be intercalated and deintercalated as much as possible in order to make the electrode have a higher reversible capacity; 4) The potential of the oxidation-reduction reaction should be low, and in conjunction with the positive electrode material, the lithium battery has a higher output voltage; 5) The first irreversible discharge has a smaller specific capacity; Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
