Dissimilar Metals Joining (Page 6)

Electric vehicles and consumer electronics depend on high-capacity, highly efficient batteries, and the demand continues to rise. Critical to producing these batteries is the successful welding of foil-to-tab joints which are often made of dissimilar materials with dissimilar thicknesses. This process is complicated, and the failure of a single joint will compromise an entire battery...

The need to be able to directly join polymers to metals is growing.  For example, in the drive to make batteries smaller, more energy efficient, longer lasting, and less expensive to manufacture, direct joining of polymers to metals offers many benefits. Recently, EWI has investigated the use of a unique, commercially available, surface treatment method...

As the demand for electric and hybrid electric vehicles continues to increase, automotive OEMs and suppliers face an array of engineering challenges. Every major system in a car – from battery to wire harness through powertrain – is affected by the transition. Methods of welding, joining, testing, and inspection all must be re-evaluated as newer,...
