LiFePO4 is a potential positive electrode material for lithium ion batteries. We have experimentally observed an imbalance between the valence change of Fe ions and the structure change from the LiFePO4 phase to the FePO4 phase during delithiation by

A Li2S cathode has a high theoretical capacity (1166 mA h g−1); however, it is inherently an insulator. To remedy this defect, composite sulfides can be prepared with transition-metal sulfides having better conductivity than Li2S. Among them, a Li8

In liquid electrolytes used for a battery, various metal complexes are formed as a result of ion-solvent and ion-ion interactions, which strongly influence the properties of the electrolyte and thus the performance of the battery. Therefore, the stru
