IT Home, January 20 news, according to Global Science Report, a study published in 'Nature Energy' shows that scientists have developed a lithium iron phosphate battery, which can reach about 402 kilometers after charging for 10 minutes. The total mileage can reach nearly 3.22 million kilometers. IT Home is informed that this battery is a self-heating battery that can be quickly heated to 140 degrees Fahrenheit (60 degrees C) for charging and discharging. When the cathode (lithium iron phosphate) uses a thin nickel foil at one end and is connected to the negative electrode, the other end extends to the outside of the battery to form a third terminal. When electrons flow, resistance heating will quickly heat the nickel foil and heat the inside of the battery. When the internal temperature of the battery reaches 60°C, the switch will be opened and the battery can be quickly charged or discharged. In addition, the battery provides 40 kilowatt-hours and 300 kilowatts of electricity when heated, allowing the electric vehicle to accelerate from 0 to 95 kilometers per hour in 3 seconds.
