Lithium ion battery is a kind of secondary battery that mainly relies on lithium ions moving between a positive electrode and a negative electrode. Lithium-ion batteries are considered to be the most ideal automotive power battery and has been widely applied in EV industry due to the outstanding advantages including but not limited to high energy density, high open circuit voltage and wide operating temperature range. The technical bottleneck of lithium-ion power batteries is how to further increase the energy density and optimize operating performance at low temperature. Besides, how to decrease the cost for lithium ion battery is also a big problem. The higher potential end of the power supply device is called cathode materials and the lower potential end of the power supply is called anode materials. At cathode end, Lithium ion intercalation process happens during discharging cycle and lithium ion deintercalation process happens during charging.For anode end, Lithium ion deintercalation process happens during charging cycle and lithium ion insertion process happens during discharging process. Good cathode/anode materials should include but not limited to the following characters: large specific capacity density, long cycling lifetime, good rate performance, proper electric potential and relatively stable structure during charge and discharge process.

Long Cycle Life

Lithium ion battery is the choice for future generations of portable electronics and hybrid and electric vehicles due to its high energy density, power density and long cycle life compared to other battery technologies. However, current graphite anode limits its application due to the low energy density derived from layered graphitic structure and low rate capability due to the slow diffusion of Li ion in graphite. In this study, a simple and versatile approach was developed to generate nanoporous carbon sponge using the combination of hard templating and etching reaction. The electrochemical properties have been tested with these novel anode materials, which showed remarkable electrochemical performance and cycling stability. Therefore, the nanoporous carbon sponge is promising to be used as the anode materials for next generation lithium ion batteries requiring high energy density and power density.
