　　Because of the breakthrough in lithium metal battery production technology, the cruising range of electric vehicles may increase by 2 times. Whether to buy an electric car or not, the cruising range may be the most worrying issue. There is another reason for not buying. Long-lasting cars are generally very expensive, such as Tesla ModelS and MoldeX.

　　Researchers at the University of Waterloo (University of Waterloo) recently released a report that the new technology may greatly enhance the storage capacity of batteries. The new technology uses lithium metal to make the negative electrode, which is said to greatly increase the storage capacity. Research director QuanquanPang said the battery is cheap, safe, and can be used for a long time. If new batteries are installed, the range of electric vehicles can be extended from 200 kilometers to 600 kilometers.

　　Researchers combine phosphorus and sulfur into a liquid electrolyte, and the electrolyte in the battery will carry an electric charge. In the battery pack, the compound reacts with the lithium metal electrode, and then a protective layer is automatically formed. With the protective layer, two problems can be solved: the battery will not catch fire or explode; we can know whether the electrode is good and how long it can be used.

　　Pang Quanquan said: "We want to find a simple and stable technology to protect lithium metal. With this technology, we only need to add a compound, and it will work automatically."
