Ultra-fast charging lithium battery successfully developed -Lithium - Ion Battery Equipment

A few days ago, Toshiba exhibited a lithium battery that uses purple tungsten oxide as the negative electrode material at the 2018 Yokohama People and Vehicle Technology Exhibition, which can achieve ultra-fast charging. The advantages of this type of battery are obvious in a wide range of applications, from automobiles, micro/mild hybrid trains, elevators, uninterruptible power supplies (UPS) to high current power supplies.

It is understood that tungsten oxide powder developed by Toshiba Materials is used as an electrode material for new battery devices, because tungsten oxide helps electron conductivity and lithium ion diffusion to achieve ultra-fast charge and discharge. This material could enable the construction of high-power-density battery devices, enabling smaller, lighter devices. As a pioneer in the field of lithium-ion battery technology, it is very likely that new battery materials will officially enter commercial use, which may further expand the demand market for tungsten oxide.(Lithium - Ion Battery Equipment)

Purple tungsten oxide is a kind of tungsten oxide. Its appearance is purple finely divided crystal powder. It is a tungsten oxide product developed in my country in recent years. Its phase composition is W18O49. Because it has the largest mesopore volume and the smallest micropore Volume, the narrowest pore size distribution, the smallest fractal dimension, the largest average pore size and specific surface area, are the preferred materials for the preparation of ultra-fine tungsten powder or nano-tungsten powder, photocatalytic materials, petroleum catalysts, and microelectronic integrated circuit boards.

The characteristics of the battery are that both power density and energy density can be increased to 2 to 3 times that of double-layer capacitors. Energy density has also been improved compared to Li-ion capacitors designed to increase the energy density of EDLCs. In the field of capacitors, Li-ion secondary batteries are not suitable for high-output applications due to insufficient output power and difficult development. The development of this battery will make it possible to use batteries in high-output applications.

As a technology leader in the lithium battery industry, Toshiba Corporation, after exhibiting its newly developed sample battery at the exhibition, hopes to supply the new achievement as a battery material to other battery manufacturers, with huge commercial potential. If it is promoted, tungsten materials will no longer be just a bystander in the field of lithium battery manufacturing.
