(1) Theoretical Capacity of Electrode Material The theoretical capacity of the electrode material, assuming that all lithium ions in the material participate in the electrochemical reaction, is calculated using the following formula: Theoretical capacity(mAh/g)=Faraday constant F (C/mol)*Li’quantity*[1/molecules‘qunatity(mol/g)]*[1/3.6(mAh/C)] Where the Faraday constant (F) represents the charge carried by each mole of electrons, with a unit of…

Self-discharge methods of lithium batteries: static and dynamic! Lithium-ion battery self-discharge measurement methods are mainly divided into two kinds: 1) static measurement method, the self-discharge rate is obtained by standing the battery for a long time; 2) dynamic measurement method, the battery is realized in the dynamic process through parameter identification. Static measurementAt present, the…

The sodium-ion battery (NIB or SIB) is a type of rechargeable battery that uses sodium ions (Na+) as its charge carriers. In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, but it replaces lithium with sodium as the cathode material, which belongs to the same group…
