According to foreign media reports, the new study of the University of Waterloo or battery research and development will make a breakthrough progress, so that mileage of electric vehicles tripled.This breakthrough includes: the use of lithium metal anode, the material or will significantly improve the battery Energy storage.
Quanquan Pang, a Ph.D. student at the University of Waterloo, who heads the research project, said: "This technological breakthrough means the price of the battery will be cheaper and safer in the future, longer battery life and longer battery life of users. milage. '
The increase in energy storage or energy density will either boost the range of end-of-life for electric vehicles from 200 kilometers to 600 kilometers, and Pang and his colleagues had to overcome two technical challenges in creating the technology.
First of all, during the repeated charging and discharging process, the microstructure of lithium metal will change, or cause the battery fire or protection.Secondly, when the battery chemical reaction, it will produce corrosion and limit the performance of the electrode, thus affecting the use of time.
Researchers added chemicals such as phosphorous and sulfur to the battery electrolyte and overcame the two problems described above.The chemical would react with the lithium metal electrode in the cell and the researchers also coated the electrode Thin protective layer.
The method improves the battery performance, exerts the advantages of the lithium metal electrode, improves the energy storage capacity of the battery, and greatly improves the mileage of the battery without sacrificing safety or reducing the service life of the battery.
