Car battery nickel plateAlso known as battery connecting tabs, pure nickel battery sheets, battery welding tabs, etc., many people may not be very familiar with battery nickel strips. In fact, they have good spot welding performance, lower internal resistance, are resistant to oxidation and corrosion, provide longer discharge time for battery packs, and ensure stronger battery spot welding. They are designed, developed, and produced for wide applications in 18650 lithium batteries, 18650 battery packs, nickel-metal hydride and nickel-cadmium batteries, lithium-ion batteries, mobile phone batteries, laptop batteries, power bank batteries, button batteries, power battery packs, electric vehicle batteries, and other industries.

Spot welding battery tabs to connectors is generally feasible, but many people have observed the process when it comes to connecting tabs and connectors on 18650 lithium batteries. Spot welding tabs on 18650 lithium batteries is both complex yet simple. The purpose of the tabs and connectors is to link and output the performance of the 18650 lithium batteries, mainly reflected in various lithium battery packs. The main method for spot welding tabs and connectors is as follows: 1. Turn the power switch of the battery spot welder to the "on" position to power it on. 2. Confirm that all parameters of the battery spot welding equipment have been adjusted according to the right parameter settings, and prepare the materials and related tools. The tools that can be used include: dual-head spot welder, file, clamping fixture, and hex wrench. When adjusting the parameters of the battery spot welding machine, it is necessary to confirm with the quality engineering team. Operation can only proceed if the requirements are met. When spot welding 18650 lithium batteries, attention must be paid to the welding tension, which must be within the quality inspection range.

Precautions for spot welding tabs and connecting pieces of 18650 lithium batteries: 1. The specifications of the tabs must comply with the material BOM specifications. 2. Welds must not have defects such as missing welds, cold solder joints, sparks, or obvious burrs. 3. Each weld point on the tab/connecting piece must have no less than 6 points. 4. During operation, the surface pad must not fall off; if it does, the pad must be reattached before proceeding. 5. When the tip of the copper needle of the spot welding machine turns black, use a file to remove the black spot from the copper needle before resuming spot welding.
