], the level of Fermi energy of Fe2+?Fe3+ couple is related to the length of P-O bond. Silicate materials have the similar chemical stability with phosphate materials. However, lithium iron orthosilicate has a lower energy of Fe2+? Fe3+ couple than lithium iron phosphate because of the stronger Si-O bonds and the lower electron negativity ratio of Si to P. Therefore, compared with phosphate materials......
