Vitesco’s new compact transmission for PHEVs

Vitesco Technologies, the powertrain business of German parts maker Continental, has unveiled a new compact transmission for PHEVs. As a PHEV contains two separate power sources, the additional complexity can raise costs to a level that prohibits significant market penetration, says Vitesco. To solve the problem, the company has created the DHT transmission. The DHT… Read more »

Northvolt’s battery recycling program aims to source 50% recycled material by 2030

Swedish battery maker Northvolt is launching a new program, Revolt, that is devoted to recycling lithium-ion batteries. It plans to bring a pilot recycling plant online in Västerås, Sweden, in 2020, next to its existing manufacturing plant. The plant will handle NMC and NCA Li-ion chemistries. It will serve as a platform for developing and… Read more »

IBM unveils heavy metal-free battery that performs better than Li-ion

IBM Research has unveiled new battery materials extracted from seawater that it says could help eliminate the need for dangerous heavy metals in battery production. Use of the three new proprietary materials create a battery chemistry that does not use heavy metals or other substances that suffer from concerns about sourcing. Beyond the environmental and… Read more »
