What kind of negative electrode material can make the Nickel Hydride Batteries of electric vehicles fast charge in just 6 minutes?

Recently, Toshiba Corporation of Japan announced the development of a new generation of lithium batteries for electric vehicles, which can be fast charged in just 6 minutes. Once this fast-charging battery enters the mass production supporting stage, it will have a qualitative impact on the existing power industry chain.

Unlike lithium batteries that generally use graphite as negative electrode materials, this Nickel Hydride Batteries uses titanium niobium oxide as negative electrode material, which has the characteristics of high energy density and ultra-fast charging. Traditional electric vehicle lithium batteries can only be charged to about 80% of their power in 30 minutes, while the new generation of lithium batteries can be fast charged to 90% in just 6 minutes. The electric car used by Toshiba for testing finally ran about 320 kilometers after charging for 6 minutes.

This Nickel Hydride Batteries can still maintain more than 90% of its battery capacity after 5,000 charge and discharge cycles, and can still be quickly charged in a low temperature environment of minus 10 degrees Celsius. At present, Toshiba has made a new generation of Nickel Hydride Batteries samples with a capacity of 50 ampere hours and the size of a palm, and plans to improve it and strive to launch a formal product in 2019.

my country is still in the development stage in terms of hardware and software of power batteries. Previously, Professor Wang Binggang, leader of the expert group of the National New Energy Vehicle Innovation Project, delivered a special speech on "Strategic Layout and Development Thinking of the Power Battery Industry", comprehensively analyzing the development status and core technologies of the power battery industry, and proposing suggestions on the healthy and sustainable development of the power battery industry and the strategic planning of enterprises facing the industrial transformation period. In addition, although my country is a major automobile country in the world, it is still not a strong country. There is a big gap in our R&D strength, and there is a serious lack of core components of automobiles.

At present, from the perspective of foreign countries, the United States, Germany, and Japan have made relatively good plans for power batteries of new energy vehicles. These plans basically involve the entire industrial chain, from materials to batteries, system integration, to applications, to sequential utilization, resource recycling, including regulations, standards, and some test evaluations. The contents of China's current four plans involving power batteries are formulated by different government departments, and the content sets some different goals for batteries, but from the overall trend, they are all moving in a good direction.
