The reporter learned from the new energy and materials chemistry Research Office of Tsinghua University's Institute ofspecial and new energy technology that the industrialization of catalyst production of key fuel cell materials has been overcome by the joint research and development team of the hydrogen fuel cell laboratory of Tsinghua University and a technology company in Wuhan At present, the catalyst has 17 patents, with a capacity of 1200 grams per day, and the price is only half that of imported products.

Although lithium-ion batteries are the mainstream of energy storage today, the molecular and atomic basic science of charge and discharge is still a mystery According to the study of the Department of Energy Argon National Laboratory in Nature Catalysis, the research team has achieved a breakthrough in the chemical composition of the solid electrolyte interface between the electrode and the liquid electrolyte.

In recent years, the use of polymer electrolytes in lithium ion batteries has been commercialized Polymer electrolytes are both ion transfer channels in lithium ion batteries and play a diaphragm role between positive and negative electrode materials.

A new method of high-density three-dimensional graphene preparation proposed by the Suzhou Nano Institute of the Chinese Academy of Sciences and the Institute of Physics of the Chinese Academy of SciencesRecently, the team of Liuliwei of the Suzhou Nano Institute of Chinese Academy of Sciences collaborated with the Institute of Physics of the Chinese Academy of Sciences to propose a novel high-density three-dimensional graphene preparation method The relevant results were published in the "Science Report.

Graphene's performance is undoubtedly excellent, but is it suitable for lithium ion batteries? Currently, the "graphene battery" claimed in the market is an inaccurate concept To be accurate, it is basically to add a little graphene to the material to improve some performance of lithium battery, which can be called graphene-based lithium ion battery.

Most mobile phones today use lithium batteries or lithium polymer batteries It is a battery made of lithium metal or lithium alloy as a negative electrode material and uses a non-aqueous electrolyte solution.

Fuel cell vehicles, the ultimate solution for new energy vehicles, are gradually turning from ideal to reality It is understood that the battery bus carrying the "Koli Yuanxin" fuel will be delivered in late June and will be on the road in Shenzhen at the end of June.

On January 22, 2018, Changchun Jin Neng Technology Group(China) and HQ(Canada Quebec Hydropower Group, one of the world's largest power generation companies) signed in Beijing under the witness of the Canadian Prime Minister of Quebec and the Canadian Ambassador to China All solid lithium battery technology cooperation agreement.

(1) Carbon negative materials:The negative electrode materials that have been actually used in lithium ion batteries are basically carbon materials, such as artificial graphite, natural graphite, intermediate phase carbon micro spheres, petroleum Coke, carbon fiber, and pyrolytic resin carbon(2) Tin based negative electrode material:Tin negative electrode materials can be divided into tin oxides and tin composite oxides.

Introduction: cobalt prices continue to rise, supply and demand are unbalanced, reducing the proportion of cobalt has become the main way for battery plants to increase energy density and reduce costs, and the high nickel of ternary materials is an important direction for the development of new energy batteries in the futureRecently, Lijianzhong, general manager of Shengsheng Technology, said at a forum that nickel, cobalt, and manganese have accounted for 90 % of the cost of positive electrode materials in power battery applications.
