Immediately disconnect the circuit. If the lithium battery is short-circuited and the nickel part is heated, immediately disconnect the circuit and place the battery in an open environment. There will be two situations where the battery is shorted. The first is that the external circuit of the battery is short circuited, which will cause the battery to heat up if the battery is disconnected from the circuit, short circuit phenomenon. will disappear and the battery temperature will gradually return to normal values. Another situation is that a short circuit occurs inside the battery, and the battery can only be abandoned in an open environment and disposed of naturally.
The 18650 lithium battery needs to be connected in series and parallel to form a battery. Series and parallel connection is usually made with nickel-plated copper tape. However, ordinary soldering is notnot necessary when soldering the battery. positive and negative electrode plates and copper tape of lithium battery. It is easy to implement, but it is also easy to cause early damage to the battery. It is easy to loosen and spark during use, so need to use a spot welder. welding. The input and output terminals of the battery pack and the charge and discharge detection terminals of each battery need to be welded to the protection board, and can be directly welded to the corresponding points with solder.
