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.

Korean aluminium alloy boosts thermal stability

Researchers in Korea have developed an aluminium alloy for EVs that dramatically improves thermal stability, writes Nick Flaherty. The team at the Korea Institute of Material Science (KIMS) identified a new mechanism by which the nanostructures inside aluminium alloys work, and the alloys they have developed improve thermal stability by up to 140%, compared with existing aluminium ones.

Global production for custom magnetics using AI algorithms

Frenetic Electronics has launched a global production service for its custom magnetics designs, writes Nick Flaherty. Frenetic Factory produces inductors, transformers and EMI filters, based on a free web design and analysis tool called Core Optimizer. This uses AI-based algorithms trained by the engineers at Frenetic.

Carbon-fibre material can store electrical energy

A spinout from Chalmers University, Sweden, has developed a carbon-fibre material that stores electrical energy and forms part of an EV’s structure, writes Nick Flaherty. Sinonus is commercialising a conformal battery using the material that doubles as electrodes. It has demonstrated the potential of its technology by replacing AAA batteries in low-power products in its lab. It is expanding to EVs and aircraft.
