A theoretical approach to evaluate the rate capability of Li-ion battery …
We suggested that these structures could be interpreted as n- or p-type semiconductors, depending on the DOS configuration. On this basis, if the lithiated structure acted as an n-type and the delithiated one as a p-type semiconductor, the resulting cathode will only be capable of achieving a "low rate".
