According to foreign media reports, Nissan has released a new plan to replace the used batteries of LEAF models with "refabricated" batteries. Compared with the new battery, this "remade" battery gives users a certain price discount. After a long time of use, the capacity of the on-board battery of an electric vehicle will decline, which is unavoidable. Normally, the decay rate (decrease) of battery capacity is only a few percentage points, but some Nissan Leaf owners reported that their on-b

Following the fatal traffic accident of Uber's self-driving test vehicle due to the failure of its self-driving system, a Tesla Model X in California, United States, exploded after a traffic accident. The owner of the car died of his injuries after being taken to the hospital. Insiders told reporters that Tesla's good-looking data on performance and mileage can be said to be achieved on the premise of radical technology. He said that during the use of Tesla's 18650 battery, as long as there is a slig

Lithium-ion batteries are simply lithium-ion batteries, which have been widely used in some models of electric vehicles. For the first charging of lithium-ion batteries, the charging time and methods of lithium-ion batteries, the global electric network editor Yu Jiangping will be below. Explain in detail to everyone. Correct use of lithium-ion electric vehicle batteries The correct use of lithium batteries actually boils down to three points. The editor of Global Electric Vehicle Network has summarized the f

The occurrence of binder floating is mainly due to drying conditions. The drying conditions mainly include drying method (electric heating, infrared heating or steam heating), drying temperature (temperature selection), oven setting (several sections of oven), temperature gradient, etc. Liu Ping of China Electronics Technology Group Co., Ltd. studied the drying method of a certain cathode slurry. The effect of drying temperature and oven setting on the peel strength of the pole piece is shown in the figure:(Lith

On April 21, the "2018 my country New Energy Power Lithium Battery and Energy Storage Industry Conference" was held in Taizhou, Jiangsu. In the sub-forum with the theme of "opportunity, innovation and breakthrough", many power lithium battery experts, scholars and representatives of power lithium battery companies talked about the opportunities and challenges currently faced by the power lithium battery industry at the meeting. Ye Shengji, Deputy Secretary-General of the my country Associatio

Unlike traditional batteries that supply electrical energy in the form of energy storage, hydrogen fuel power cells convert chemical energy into electrical energy through the electrochemical reaction between hydrogen and oxygen. As long as there are sufficient hydrogen and oxygen sources (air sources), this conversion The process can go on forever and achieve zero pollution discharge. It is a new type of power generation technology that is efficient, safe, clean and flexible. At present, hydrogen fuel power cells a

If we say that the dilemma of lead-acid batteries flowing to small workshops is still there, then lithium-ion batteries, which are about to reach the peak of scrapping, will not escape the dilemma, and the situation is even worse. It is understood that electric vehicles may be scrapped after 5 to 7 years of use, and a large amount of scrap is expected to begin in 2018. According to the forecast of my country Automotive Technology Research Center, by 2020, my country's cumulative scrapped power lithium batteries

At present, the two important directions of power lithium battery recycling in my country are cascade utilization and dismantling recycling. When the power lithium battery used in cascade is no longer usable as a battery, its value as a material still exists, so the cascade utilization is down. The battery will eventually be dismantled and recycled. It can be said that how many power lithium batteries are currently produced, and how many waste power lithium batteries will be dismantled in the future. As the termina

The safety of new energy vehicles has always received great attention, and everyone's concerns are also related to batteries, including fire and explosion, leakage, wading, radiation, and so on. In fact, car companies will take these issues into account when developing new energy vehicles, and will deal with them or make concessions in some respects for safety. Here, it is important to understand the cooling system of the power lithium battery. The quality of the cooling performance will directly affect the
