A typical Li-ion cell is constructed of nickel plated cold rolled steel.

In battery pack manufacturing, the cells are often already assembled and the engineer is challenged with coming up with a design to join them in series and parallel to deliver optimum energy. Let’s see how the three welding technologies measure up: The following graphic shows five key challenges typically encountered in tab to cell battery connections: The challenges listed above can be broken down into desirable solutions. Tab to Cell Connection Manufacturing Challenges
We’ll focus on:Īnother viable option – ultrasonic welding – is not covered in detail but is shown in a matrix summing up how the technologies compare. In this post we will examine the key challenges in tab to cell connection and see how the available welding technology options measure up. It’s a tall order, and that is why special attention must be paid to the welding system selected for EV battery pack manufacturing. Some of these goals can be achieved by improved cell chemistries and battery pack design, but others can be improved only by considering the joint quality between the batteries and the current collectors.
And since the e-mobility market is so rapidly expanding, there are additional manufacturing challenges, including the demand for higher throughput and quality. Translated into manufacturing goals, the batteries need to possess higher capacity with negligible energy loss delivering to the drivetrain, higher current carrying capacity for charging, and be made of light-weight, lower cost materials. The challenges encountered in bringing this technology to market include the demand for reduced weight, expanded range, faster charge times and lower costs. According to Gartner, e-Mobility “represents the concept of using electric powertrain technologies, in-vehicle information and communications technologies and connected infrastructures to enable the electric propulsion of vehicles and fleets.” A BIG piece of the e-Mobility puzzle is battery and battery pack manufacturing. This electrification – which applies across several sectors – is neatly wrapped up in new terminology: e-Mobility or Electro Mobility. You have probably noticed the increasing numbers of electric vehicles and other transportation devices on the roads today including private automobiles, transportation trucks, bikes, motorcycles, scooters and other modes of transportation driven by electrical power, all of which is provided by stored energy in batteries.
