Northvolt acquires Cuberg, will commercialize next-gen lithium metal battery cells

Northvolt has announced the acquisition of Cuberg, a battery company delivering lithium metal cells produced on existing lithium-ion manufacturing lines. Cuberg says its cells, which are based on its electrolyte technology for lithium metal anodes, deliver more than 70 percent increased capacity versus comparable lithium-ion cells. Building on this foundation, Northvolt and Cuberg will expand… Read more »

Draper wins patent for electrostatic motor

Draper is developing a family of electric motors and generators based on fundamentally different principles from common e-motors used today. Underpinning the initiative is a recent patent on aspects of the technology. Draper says its approach to electric motors has numerous advantages over conventional electric motors, including lower weight, higher efficiency, higher specific power and… Read more »

Volvo Penta and TICO partner to develop e-trucks

Volvo Penta has joined forces with terminal tractor manufacturer TICO to develop electric terminal truck prototypes. Terminal tractors, also known as yard goats, are used to move cargo in ports, distribution centers, and rail terminals. They are considered an ideal application for EVs. “TICO has always been at the forefront of bringing alternative powertrain solutions… Read more »

Evonik launches new silicon-carbon anode material

Evonik has introduced the silicon-carbon composite material Siridion Black as a new anode material for lithium-ion batteries, claiming that it increases energy density, and improves fast-charging capability and energy efficiency. “Until now, graphite has been used as an anode material in lithium-ion batteries, but batteries with a higher capacity need new materials that also allow… Read more »

MIT study details plunge in lithium-ion battery costs

MIT researchers analyzed three decades of studies that examined the decline in lithium-ion battery prices, and found that costs have dropped by 97 percent since they were first commercially introduced in 1991. This rate of improvement is much faster than many analysts had claimed, and is comparable to that of photovoltaic panels, which some had… Read more »

Nexperia and UAES partner on gallium nitride power systems

Semiconductor manufacturer Nexperia has announced a partnership with United Automotive Electronic Systems (UAES), a provider of automotive powertrain and body control systems. The program will focus on power systems for EVs, with the aim of jointly developing automotive applications using gallium nitride (GaN) technology. UAES is currently using Nexperia GaN FETs in EV projects such… Read more »
