Discharge Process

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.

Lithium-ion hybrid capacitors (LICs) are regarded as one of the most promising next generation energy storage devices. Commercial activated carbon materials with low cost and excellent cycling stability are widely used as cathode materials for LICs, however, their low energy density remains a significant challenge for the practical applications of LICs. Herein, Na0.76V6O15 nanobelts (NaVO) were prepared and combined with commercial activated carbon YP50D to form hybrid cathode materials. Credit to the synergism of its capacitive effect and diffusion-controlled faradaic effect, NaVO/C hybrid cathode displays both superior cyclability and enhanced capacity. LICs were assembled with the as-prepared NaVO/C hybrid cathode and artificial graphite anode which was pre-lithiated. Furthermore, 10-NaVO/C//AG LIC delivers a high energy density of 118.9 Wh kg−1 at a power density of 220.6 W kg−1 and retains 43.7 Wh kg−1 even at a high power density of 21,793.0 W kg−1. The LIC can also maintain long-term cycling stability with capacitance retention of approximately 70% after 5000 cycles at 1 A g−1. Accordingly, hybrid cathodes composed of commercial activated carbon and a small amount of high energy battery-type materials are expected to be a candidate for low-cost advanced LICs with both high energy density and power density.
