Imec, a Belgian research firm focused on nanoelectronics, has unveiled a solid-state Li-metal battery cell with an energy density of 400 Wh/liter at a charging speed of 0.5C (2 hours). As part of a larger engineering roadmap for solid-state batteries, imec aims to surpass wet Li-ion battery performance and reach 1,000 Wh/L at 2-3C by… Read more »

Study explores lightweighting potential of structural foam in vehicle bodies
In a joint study, German chemicals company Henkel and engineering consultancy RLE International have examined the potential of high-performance structural foam for lightweighting in automotive body and closure parts. Henkel says the study shows that fiber-reinforced polymer components with structural foam ribbing and reinforcements can save more than 40 kg of weight per car compared… Read more »
GBatteries says its AI-powered protocol can charge an EV in 5 minutes
GBatteries has launched an AI-powered charging protocol designed to charge conventional Li-ion batteries as quickly as a car can be filled with gasoline. The company says its system can charge a 60 kWh EV pack to 119 miles of range in 5 minutes. Operating at the intersection of artificial intelligence, electrochemistry, signal processing, and high-power… Read more »
Battery testing start-up Novonix has spun off PUREgraphite to manufacture anode material in the US
Batteries are ubiquitous in our modern lives. Take a look around you and count how many items need be plugged in and recharged. If you’re at your desk, the answer might be four or five. If you’re out for a run, perhaps two or three. If you’re in a garage, there may only be one,… Read more »
EU regulators charge BMW, Daimler and VW with colluding to evade emissions rules
Are the authorities “piling on” the Volkswagen Group? In 2017, the poor little automaker pleaded guilty to fraud and obstruction of justice in the dirty diesel debacle, and has already agreed to shell out some $30 billion in atonement. Now the mean old US Securities and Exchange Commission has sued the company and ex-CEO Martin… Read more »
EU awards $4.5 million grant to UpScale Project to reduce EV development time using AI
UpScale, an EU project aimed at using AI for more efficient EV production, has received a €4 million ($4.5 million) grant from the European Commission to develop computer simulations to aid in the development of EVs. UpScale (Upscaling Product development Simulation Capabilities exploiting Artificial intelligence for Electrified vehicles) consists of 11 companies and European entities… Read more »
A closer look at DC-DC converters
As far as we know, all EVs in production by major automakers use a conventional lead-acid battery for the 12 V system (surprising, but true – more on why in a bit) and this battery needs charging, just as it does in an ICE vehicle. While you could hang an alternator off the traction motor… Read more »
LeasePlan and Allego offer new home-to-office charging service
Car sharing firm LeasePlan and charging solution provider Allego have announced a new partnership to provide LeasePlan EV customers with access to personal chargers at home and at work. The charge points are designed to enable drivers to be automatically reimbursed for load balancing services provided to utilities. The scheme will initially be rolled out… Read more »
China’s Shanghai Energy plans a massive increase in battery separator production
China is steadily positioning itself at the forefront of Li-on battery production. One sign of this is a massive ramp-up of the production of wet-process separators (separators are a critical component of Li-on batteries – they keep the anode and cathode from touching, while allowing ions to pass through). Shanghai Energy has announced that it… Read more »
Chinese companies increasing their pursuit of lithium resources
A recent report from metals and minerals research firm Roskill details how China is quickly working to increase its control of the lithium supply chain to support the rapid growth of its lithium-ion battery industry. The report provides examples of several major players who have recently announced or completed acquisitions. CATL, one of China’s largest… Read more »
