| Abstract | The characteristics of rechargeable lithium-ion polymer batteries incorporating a nanowire TiO2(B) anode, and containing LiFePO 4 or LiNi0.5Mn1.5O4 cathodes, are discussed. The use of titanate anodes provides superior safety, overcharge protection, and high power because they can can be used in the form of nanomaterials. By using an electrode such as the TiO2(B) nanowires, which operates at 1.5 V versus lithium, little or no electrolyte decomposition occurs during the cell operation. This allows the use of high-surface-area nanomaterials with high safety and no need for electronic control of cell charging to avoid overcharge. The use of a gel-type polymer electrolytes in place of a standard liquid electrolyte can also enhance the safety of lithium-ion batteries. |
