Then, the power is led out through the metal terminal 14 to the circuit of the load 11, and the terminal is directly connected to the battery pole. The contactor's money terminal and the battery pole portion cause high contact resistance, so the battery is turned on. The contact area will rise due to impedance and consume battery power. In order to solve the above problem of contact resistance, please refer to Figure 2. The battery industry also has a nickel-metal #15 through spot welding to export the battery 10 power, mainly to take the metal month 15 and the battery 1 After the pole tip 12 and the negative pole tip 13 are spot-welded, the contact resistance is greatly reduced, and the nickel metal has high oxidation resistance. It is worth noting that by spot welding, the battery power is exported, and the high temperature of the soldering process is transmitted through the metal tip of the battery into the battery to cause the battery to be inside. The damage of the crucible is as follows: the battery seal is damaged, the gas barrier is broken, and the separator of the positive and negative electrodes is broken, which causes the battery to be unusable or the battery to be used for a period of time and fails to be used.
