A new type of anode material with fast charging, high safety and high energy density, new hope for lithium battery!   Currently, in most commercial lithium-ion batteries (LIBs), two types of negative electrode active materials are usually used. One, the most common is battery graphite, which has a high energy density. LIBs equipped with graphite negative electrodes can be used for cars to drive hundreds of miles without charging. However, during the fast charging process, lithium metal is prone to deposit lithium dendrites on the negative electrode side, which brings extremely serious safety hazards. Second, lithium titanate, a safer alternative, can achieve fast charging, but usually results in a significant drop in energy density. Figure 1: Voltage curve and structure characterization of original and lithiated DRS   【Introduction to Achievements】 Recently, Professor Ping Liu and Professor Shyue Ping Ong from the University of California, San Diego, Professor Huolin Xin from the University of California Irvine, and Researcher Jun Lu from Argonne National Laboratory (corresponding author) discovered a new type of anode material. This material allows lithium-ion batteries to be safely recharged thousands of times in minutes. Specifically, the researchers reported a disordered rock salt oxide Li3+xV2O5 (DRS-Li3+xV2O5), which can reversibly circulate two lithium ions at a voltage of 0.6V. Compared with graphite (0.1 V), it has a higher voltage and can effectively avoid lithium dendrites caused by fast charging.   In addition, compared with the commercially available fast-charge lithium titanate (Li4Ti5O12, 1.5 V), Li3+xV2O5 has a lower voltage, a higher specific capacity, and a higher energy density when forming a full battery. Therefore, this new type of disordered rock salt anode Li3+xV2O5 is in the middle position: it is safer than graphite, and the energy density of the composed battery is at least 71% higher than that of Li4Ti5O12. More importantly, after using the Li3V2O5 anode material, the capacity decay is negligible after 1000 cycles. Not only that, it also has excellent rate performance, which can reach 40% capacity within 20 seconds.   Combined with first-principles calculations, this work reveals that the optimal conduction path of lithium ions during the lithium insertion process of Li3+xV2O5 will change due to the redistribution of lithium, which also explains why the material has fast lithium ion conduction characteristics and Lower average cycle potential. Related research results were published on Nature with the title "A disordered rock salt anode for fast-charging lithium-ion batteries". The first authors of this article are Haodong Liu and Zhuoying Zhu.

Lithium battery separator war In the new energy war, as Chinese lithium battery companies grew up, unwilling Americans began to think of the internal battery materials. On October 30, 2019, Celgard, a former lithium battery separator giant, sued Xingyuan Materials and its subsidiary "Xingyuan American Research Institute" in Shenzhen, China, in the Oakland Division of the Northern District Court of the US Federal District of California. The reasons for litigation are: "Infringe its patent rights, infringe on trade secrets, unfair competition, induce breach of contract, and intentionally interfere with potential economic relations." Although it was dismissed by local courts in the United States more than three months later, the long soap opera-like "lawsuit" has not ceased. After all, for Celgard, there are not too many serious things that can be done now. In the field of dry membranes that was once proud, Celgard has gradually lost market share due to the gradual loss of technology and price advantages. Beginning in 2013, LG Chem, SK, Sumitomo, MTI, Targray... Any half of the influential battery separator companies have been on Celgard's prosecution list. But embarrassingly, Celgard mostly ended in defeat or settlement. Reported by Zoe Jiang AOTELEC Battery Technology Company 2020-7-2

5 companies competition on Million Miles battery Overall, long life, high battery life, and low cost have become the main development direction of power batteries. All battery companies are running fast on the new technology track. In 2019, Tesla announced that it had developed a new type of battery that would allow its battery life in electric vehicles to exceed 1 million miles (1.61 million kilometers), more than double its current battery life. In May 2020, Tesla announced that it had improved its new "Million Mile Battery", which further reduced cobalt and increased the energy density of the battery, while reducing costs. On June 23, Musk said that Tesla will hold the "Battery Day" on September 15. Industry speculation may be announced at that time about the "millions of miles" battery news. However, before waiting for Tesla to disclose more detailed information, the CATL took the lead in commercializing the "Million Mile" battery. On June 8, Zeng Yuqun, chairman of CATL, announced that the company is preparing to produce batteries with a life span of 16 years and a mileage of 1.24 million miles (about 2 million kilometers). It is understood that the core of the CATL self-repairing long-life battery technology is to slow down the capacity decay rate, that is, to control the rate of active lithium consumption. The battery capacity decline is related to the cathode electrode, anode electrode, and battery electrolyte. There are already companies such as Tesla, CATL, General Motors, SVOLT and BYD in the "Million Mile" battery track. It is expected that more battery companies and OEMs will join the camp in the later period.
