Why does Tesla prefer ternary lithium-ion batteries?

What is the future of battery technology? Lithium iron phosphate battery is a kind of lithium ion battery. At present, BYD e6, BAIC ev160, Tengshi and other electric vehicle manufacturers are all using it as a vehicle power source. The thermal stability of lithium iron phosphate batteries is currently the best among lithium-ion batteries for automobiles. When the battery temperature is at a high temperature of 500-600℃, its internal chemical components begin to decompose, and the internal chemical components of lithium cobalt oxide batteries, which are also lithium-ion batteries, are in an unstable state at 180-250℃. In other words, the lithium iron phosphate battery is the safest battery among the lithium ion batteries, which is why the lithium iron phosphate battery has become one of the important categories of electric vehicle batteries. Why does Tesla favor ternary lithium-ion batteries? [Dry goods] A brief analysis of new energy vehicle batteries and a list of future technologies. The weight and energy density of the ternary lithium-ion battery used in the Tesla model is about 200Wh/kg, and The energy density of a lithium iron phosphate battery is about 150Wh/kg, which means that a ternary lithium ion battery of the same weight has a longer range than a lithium iron phosphate battery. However, when the temperature of the ternary lithium-ion battery itself is 250-350°C, its internal chemical components begin to decompose, which puts forward higher requirements on the battery management system. Take Tesla as an example. The whole car is equipped with more than 7,000 18650 ternary lithium-ion batteries. The battery management system needs to monitor the usage status of each battery, which undoubtedly adds to the control difficulty of the battery management system. Fuel power battery is the most ideal energy source for future vehicles [Dry goods] Brief analysis of new energy vehicle batteries and a list of future technologies Fuel power batteries are generators that convert chemical energy into electrical energy, not batteries. Its energy source mainly relies on the continuous supply of fuel and oxidant. It has high energy conversion efficiency, no pollution, long life, and stable operation. It is recognized by the industry as the best energy source for future automobiles. In today's market, fuel-powered cell vehicles are not far away. At the end of last year, Toyota officially launched the MIRAI, which is a hydrogen fuel-powered battery car with a mileage of about 700 kilometers and only discharges water. The working principle of MIRAI is that the hydrogen in the hydrogen fuel tank reacts with the oxygen inhaled in the front of the car in the fuel power battery, and electricity is generated to drive the motor of the car, and the remaining energy generated by the reaction is stored in the energy storage battery. The two fuel tanks at the rear of the car can store up to 5 kg of hydrogen fuel, which can usually be refueled within 3 minutes.
