1 The dangers of lithium batteries Lithium battery is a potentially dangerous chemical power source from its own chemical characteristics and system composition. 1 High chemical activity Lithium is an element of the main group I of the second period of the periodic table and has extremely active chemical properties. 2 High energy density Lithium battery has extremely high specific energy (≥140Wh/kg), which is several times that of nickel-cadmium, nickel-hydrogen and other secondary batteries. If t

1. Why can lithium iron phosphate return? When electric vehicles were first developed in the early years, we would see that the power lithium batteries of many vehicles used lithium iron phosphate. However, in recent years, the reputation of ternary lithium has become more famous. When buying a car, you will even ask "what is this car?" Is the battery ternary lithium?" Lithium iron phosphate battery seems to have become a type of battery that has been eliminated. However, the recent news that TSLA

The person in charge of CATL, who has always been low-key, gave a rare interview to a reporter from the Shanghai Stock Exchange today, revealing that the company's next-generation R&D direction includes cobalt-free technology, and strives to reduce the cost of lithium batteries per kilowatt-hour to $100 by 2025. How is this going? A long-life battery has been developed The relevant person in charge of CATL revealed to the reporter of the Shanghai Stock Exchange that in terms of battery life, the co

The traditional view is that the thermal runaway of lithium batteries is caused by the internal short circuit caused by the shrinkage or even melting of the polyolefin separator caused by the heating inside the battery [1]. The latest research shows that the mechanism of thermal runaway of the battery is different for different battery systems and abuse conditions. Factors such as cross-reaction between positive and negative electrodes in high-specific energy batteries, lithium precipitation on the negative side ca

CATL has become the "overlord" of the global power lithium battery in ten years, and has gradually formed a positive cycle business model with leading technology, low battery cost, and large production and sales scale. Based on this, CATL is a company that is willing to engage in technology. This is one of the reasons why CATL has created an industry myth in just ten years; it is also one of the reasons why CATL can buck the trend and expand its market share despite the first negative increase in sales

CATL, which has lost the global market share of power lithium batteries, wants to "recover lost ground" by preempting the commercialization of new battery technologies. On June 10, CATL announced the launch of a new long-life battery, which will use self-healing long-life technology. "At present, it is possible to start accepting orders from OEMs." The relevant person in charge of CATL told a reporter from Beijing Business Daily. At present, as an important supporting power lithium battery fi

The problem of the cliff-like decline in the cruising range of electric vehicles in winter has not only "dissuaded" a large number of potential customers in recent years, but even the owners who bought the car mentioned it, and most of them felt that it was not a pleasant experience. "The electrical appliances such as air conditioning, heating and entertainment systems in electric vehicles really affect the cruising range. Especially in winter, the power consumption of air conditioning and heating

With BYD Han, Xpeng P7 and other long-range pure electric new cars delivered this month, several star products have been added to the family of electric long-range vehicles over 600km. According to the incomplete statistics of my country's battery network, at present, domestic pure electric vehicles with a battery life of more than 600km mainly include Hechuang HYCAN007 of GAC NIO, AionLX/AionV of GAC New Energy, Xiaopeng P7, BYD Han, etc. models. It is expected that in the next few months, there will also b

Financial Associated Press (Beijing, reporter Xu Hao), the upcoming June, echoing the frequent fire accidents of new energy vehicles, is the industry's attention to solid-state batteries with higher safety and energy density. Under this industry trend, traditional vehicle manufacturing companies including Volkswagen have further strengthened their layout in the field of solid-state batteries. "If all solid-state batteries are used, the cruising range of the company's EV model e-Golf can be increased
