A lithium ion battery using nanostructured Sn–C anode, LiFePO4 cathode and polyethylene oxide-based electrolyte

In this work we report a lithium ion battery based on a nanostructured Sn–C anode, an improved lithium iron phosphate, LiFePO4, cathode and a polyethylene oxide-based electrolyte. The battery has a solid-like configuration, high safety and can operate at room temperature with a stable capacity of the order of 120 mAh g− 1 at a voltage of 2.8 V. These properties candidate the battery as very appealing energy accumulation system suitable for environmentally friendly, safe, applications.
