In a test experiment, what happened when an 18650 cylindrical lithium-ion battery was subjected to flames. In the experiment, when the lithium ion was heated to a high temperature of 600 degrees or more by the flame, the flammable battery internal materials such as the electrolyte were ejected from the safety valve and caught fire.
The definition rule of cylindrical lithium battery: such as 18650 type, which refers to a cylindrical battery with a diameter of 18mm and a length of 65mm.
Cars are men's cars, and new energy electric vehicles are rapidly emerging around the world, and power batteries have also become the focus of everyone's attention. Take Tesla as an example, it's cool and cool. It is said that Tesla tested many types of batteries when developing electric vehicle batteries, and finally adopted 18650 cells as the technical route for new energy electric vehicle batt
Nowadays, there are many kinds of brands in the lithium battery market. Giving a "good name" to a lithium battery product will not only add value to the product itself, but also become a selling point in the market.
The advantages of the 18650 lithium battery are known to many users, but for the environmental protection issues advocated by the society today, let's talk about how harmful the 18650 lithium battery is to the environment?
Lithium polymer batteries refer to lithium ion batteries that use polymers as electrolytes, and are divided into two types: "semi-polymer" and "full-polymer". "Semi-polymer" means that a layer of polymer (usually PVDF) is coated on the separator to make the adhesion of the cell stronger, the battery can be made harder, and its electrolyte is still a liquid electrolyte.
