　　Cylindrical battery structure

　　If you pay attention to the power battery, you will find that the cylindrical 18560 battery is the battery type that has been studied the most and has the most technical discussions. The monomer is mainly composed of positive electrode, negative electrode, diaphragm, positive electrode and negative electrode collector, safety valve, overcurrent protection device, insulating part and shell. For the shell, there were many steel shells in the early days, but currently aluminum shells are the main ones. The safety valve and PTC are shown in the figure below.

　　Individual overcurrent protection devices have different designs for each manufacturer. According to different safety requirements, the price will be different and can be customized. General safety devices mainly include PTC positive temperature coefficient resistors and fuse devices.

　　PTC, when there is an excessive current, the resistance heats up, and the temperature accumulation promotes the rise of the PTC resistance value. When the temperature exceeds a threshold, it increases suddenly, which is equivalent to isolating the faulty cell from the overall circuit to avoid further thermal runaway. happened.

　　The fuse device, in principle, is a fuse. When an excessive current is encountered, the fuse is blown and the circuit is disconnected.

　　The difference between the two protection devices is that the former is recoverable, while the latter is one-time protection. Once a fault occurs, the system must replace the faulty cell to work normally.
