澳洲10网上投注Aluminum, Copper & Nickel tab strips and bars for battery packaging
Battery tabs play an important role in lithium-ion cell manufacturing. Typical large format lithium-ion cells use copper for the anode foil (current collector) and aluminum for the cathode foil. A ‘foil-to-tab’ weld is needed to gather all the current collector plates (foils) inside the cell and join them to a tab. The tab then exits the cell casing, which allows the cell’s energy to be transferred to an external source.
There are two foil-to-tab welds in each li-ion cell, and hundreds of cells in a standard lithium-ion battery pack.
Our battery tab portfolio is built to meet the modern requirements for lithium-ion battery and energy storage manufacturing. It includes aluminum (Al) tabs for positive electrodes, and copper (Cu) tabs for negative electrodes. In addition, we can supply copper-plated Aluminum (Cu-Al), nickel (Ni), and aluminum-clad copper tabs. Our tabs are available with or without polypropolene film, and black or yellow DNP.
