High-performance Sn@carbon nanocomposite anode for lithium-ion batteries: Lithium storage processes characterization and low-temperature behavior

The anode can deliver a capacity of 500 mAh g−1 for more than 300 cycles, most of them at 1C or higher charge/discharge rate, which confirms its very high, stable cycling performances. Moreover, this tailored nanostructured anode retains a relevant amount of capacity even in very demanding cycling conditions, as the case for very low temperatures. These results make the proposed Sn-PMCMT an ideal candidate anode for high-performance Li-ion batteries able to operate in a wide array of operating conditions.
