Minimal Irreversible Capacity Caused by the Lithium Insertion into Materials of Negative Electrodes in Lithium-ion Batteries

The minimal irreversible capacity of negative electrodes of lithium-ion batteries, necessary for their stable operation, is theoretically evaluated. The theoretical values are compared with real ones reported in literature. It is shown that the real values of the irreversible capacity for electrodes made of carbonaceous materials exceed several times the minimal required values; the real irreversible capacity of silicon-based electrodes exceeds the minimal values by 2 to 3 orders of magnitude.
