8.4 v Lithium Ion Battery Can Charging Fast

The characteristic of 8.4 v lithium ion battery is that the power density and energy density can be increased to 2 to 3 times that of EDLC. Compared with lithium ion capacitors which designed to increase the energy density of EDLC, the energy density of 8.4 v lithium ion battery has also been improved.

Recently, a negative electrode material can achieve super fast charging lithium-ion battery into people's sight when it is using tungsten oxide (WO3). The application range of this type of battery is widely used in large current power supply, from energy recovery to automobile and construction machinery, because it can realize the input and output of large current.

The characteristic of the battery is that the power density and energy density can be increased to 2 to 3 times that of EDLC. Compared with lithium ion capacitors which designed to increase the energy density of EDLC, its energy density has also been improved.

As lithium ion secondary batteries which made by anode material, tungsten oxide can achieve ultra-high speed charge and discharge.

In the EDLC field, the Li ion secondary battery is not suitable for high output applications because of insufficient output power and development difficulties, and the development of this battery will make it possible to use batteries in the field of high output power use. In this study, we developed a kind of powder material called WO2.72, which can be obtained by WO3 under the anoxic condition to enhance the electronic conductivity. Because of its low internal resistance and excellent Li ion diffusion, the material can be used as the anode of the battery to achieve high current charge and discharge. Especially in the low-temperature environment, the discharge characteristics are excellent, and even at-40 C, the discharge characteristics of EDLC still have the same or higher rate characteristics. But in the past, the rate characteristics of Li ion two batteries and Li ion capacitors at low temperatures have always been an unsolved problem.
