Volkswagen explains why batteries, not fuel cells, are the right choice for passenger cars

The debate over hydrogen fuel cells refuses to go away. The founders of Tesla considered hydrogen and other energy storage media before deciding that batteries were the best choice for electric powertrains, and have explained their reasoning in great detail several times since. Toyota, on the other hand, continues to insist that fuel cell vehicles… Read more »

Majority of demand for nickel and cobalt coming from 5 battery suppliers

In 2019, over 59,000 tons of nickel and 14,400 tons of cobalt were deployed globally in passenger EV batteries, a one-year increase of 39% and 34%, respectively, according to data from Adamas Intelligence’s EV Battery Capacity and Battery Metals Tracker. Panasonic used  51% of the global market share of nickel (down from 56% in 2018),… Read more »

UC San Diego’s research roadmap for the challenges of solid-state batteries

The race is on to develop batteries that are less expensive, safer, longer-lasting, more energy-dense, and easily recyclable. All-solid-state batteries show promise, but obstacles to their wide-scale adoption remain. In a review article published in Nature Nanotechnology, nanoengineers at the University of California San Diego (UCSD) offer a research roadmap that discusses four challenges of… Read more »

The battery that breathes—Freudenberg’s pressure compensation system

EV batteries require pressure compensation both under normal operation and during emergency ventilation. Freudenberg Sealing Technologies’ DIAvent component combines these two functions into a single design, which will be used in the ABT e-Caddy and ABT e-Transporter, two Volkswagen vans that are popular in Europe and Mexico.  To reduce battery weight and size, ABT uses… Read more »
