The 4680 battery is a new model of lithium-ion battery, a new type of large battery announced by Tesla in 2020, and its name "4680" represents its size specifications, with a diameter of 46 mm and a height of 80 mm. This type of battery has a larger volume than the traditional 18650 and 21700 batteries, and is a lithium-ion battery with higher energy density and higher power output.
The 4680 battery has a higher energy density than traditional batteries, which means that more energy can be stored in the same volume, providing a longer range. At the same time, it can provide higher power output, making it better in high-power demand scenarios such as acceleration and high-speed driving. In addition, due to large-scale manufacturing, it is expected to reduce manufacturing costs, thanks to the larger size, this battery has a larger surface area to dissipate heat, reduce the degree of heat, and improve the safety and life of the battery, the following is sorted out the brands that have launched the 4680, let's take a look.
On February 19, 2022, Tesla announced that it had produced 1 million 4680 batteries at a pilot plant in California. The 4680 will be used in the Model Y model.
On March 19, 2021, BAK was the first to release the 4680 battery, which will be put into mass production in 2022.
EVE's official website has accepted the customization of 46xx size large cylindrical batteries, and introduced the relevant advantages of large cylindrical batteries on the official website.
BYD 4680 battery cell cylindrical design, using green cell sleeve film color, nominal capacity: 15000mah@05c；Nominal voltage: 32v；Nominal energy: 48wh; AC internal resistance: 8m.
With the continuous development and optimization of 4680 cells, it is expected to become the mainstream battery type in the field of electric vehicles and energy storage systems. Overall, the 4680 battery cell represents the future of electric vehicles and energy storage, with innovative design and superior performance that will revolutionize our lives and the environment.
