Samsung solid-state battery tech under development doubles energy density

Samsung logoSamsung announced last week that is developing new solid-state batteries that could offer double the energy density of current lithium-ion batteries. This would be a major breakthrough for electric cars. Greater energy density means more energy can be stored in a given volume, allowing for increased range without increasing the physical size of a...

Fast-charging method claims to help electric-car batteries last longer

BMW i3 and Volkswagen e-Golf electric cars using Combined Charging System (CCS) DC fast chargingHeat is the enemy of electric-car battery packs. And while high-performance driving might heat up the packs momentarily, few things you can do to the pack come close to the potential wear and tear inflicted by the kind of charging you’d need to use on a highway trip: DC fast charging. Using what they term “the same industry...

Report: Tesla considering battery format change in China

Tesla starts delivery of Chinese-made Model 3 sedans on December 30, 2019Tesla has made major investments into cylindrical battery cells, using 18650-format cells in the Model S and Model X, and 2170-format cells in the Model 3 and upcoming Model Y. The company also manufactures these cells at its Gigafactory with Panasonic. But now, perhaps combined with other key changes, the automaker appears ready to test a...

Researchers say energy-dense lithium-sulfur batteries may double EV range

Researchers at Monash UniversityResearchers in Australia say that advancements made in cathode durability could make lithium-sulfur batteries a reality for electric vehicles soon. The news was reported Friday by IEEE Spectrum following a paper published Monday by researchers at Monash University in Science Advances. In both, researches say lithium-sulfur's lower weight and...

Rivian electric trucks’ battery packs more energy into less space

Rivian electric car platformUntil the infrastructure can catch up—and well beyond then, if you’re talking about go-anywhere electric trucks like those from Rivian—big batteries will be a necessity for getting more people switching to EVs. Rivian has accepted that from the start with its R1T electric pickup and R1S electric SUV, with battery packs that start...
