New manufacturing innovations offer EV weight loss

The quest for greater efficiency and range in EVs is often focused on battery technology and drivetrain efficiency, but fundamental physics point to another key factor in the equation: weight. The increasingly popular move from 400V to 800V systems saves weight through lighter cables, but even reductions of a few kilogrammes can make a tangible difference and one company is exploring innovations in sheet metal that could change the game.

Magnesium electrolyte sparks next-generation battery design

University of Waterloo researchers have made a key breakthrough in developing next-generation batteries made of magnesium instead of lithium. When the idea to create batteries using magnesium was first shared in a seminal academic paper in 2000, the novel design didn’t provide enough voltage to compete with lithium-ion batteries.

Gap fillers and TIMs

Peter Donaldson examines the shifting demands on thermal interface materials and suppliers’ innovative responses. Thermal interface materials (TIMs), including gap fillers, are crucial for managing heat in battery packs, sensors and electronics in e-mobility applications. Their developers have to meet changing demands from battery builders and vehicle OEMs as they implement novel architectures moving into cell-to-pack, cell-to-chassis and cell-to-body schemes.
