Why does Tesla use 18650 lithium battery packs?

In fact, why Tesla chose the 18650 lithium battery pack is his reason. First of all, Tesla uses the 18650 battery of Panasonic of Japan. It is known that Japan is very good at making batteries. The solid-state batteries developed at present are all in The forefront of scientific research in the world. The Panasonic 18650 lithium battery pack used by Tesla uses NCA as the positive electrode and has designed a complex battery management system to ensure and improve the efficiency and safety of battery work as much as possible. Tesla uses 18650/20700 batteries, to be more precise, it uses cylindrical lithium batteries. Because as a shape standard, 18650/20070 can be either a lithium battery, a lithium polymer battery, or an iron-lithium battery. The 18650 lithium battery pack itself is a mature standard (developed by SONY). Compared with other encapsulated lithium batteries, it has much better safety. The shape of the shell is firm and pressure-resistant, the positive and negative electrodes are strictly separated, and the electrolyte is not easy to precipitate. At the same time, the energy density is high, which is simply more power. And because of the mature technology, the consistency of the batteries is also very good, and the price is even more affordable. Many of the various power banks on the market are 18650 batteries, which are safe, reliable, durable and cheap in daily environments, which are their advantages. The single battery is basically useless, but this does not affect the normal operation of the other thousands of batteries. These batteries are inter-connected and independent. If there is a leak in the battery system, then for the 18650 battery, look for the problem. It's very accurate, it can be accurate to a certain battery, so it is much easier to replace the battery. The 18650 lithium battery is the longest used lithium battery and still exists at present. The shadow of the 18650 lithium battery pack can be seen in many places. About 7,200 18650 batteries are placed in the base of the Tesla car, which supplies the car with super kinetic energy through series-parallel connection and Tesla's unique intelligent system.
