Novonix launches battery testing system for non-destructive electrolyte analysis

Novonix, a battery testing equipment manufacturer, is launching a differential thermal analysis system capable of non-destructive electrolyte analysis of Li-ion cells. To better understand battery failure, the system measures and monitors the evolution of the liquid electrolyte over a battery’s lifetime and provides information about its composition, quantity, salt consumption and solvent reactions. Thermal signature… Read more »

VW and Northvolt form European Battery Union to advance EU battery research

VW and Swedish battery maker Northvolt will lead a new consortium, the European Battery Union (EBU), which aims to push battery research forward in Europe. Through the EBU, the partners plan to research the entire battery value stream – from raw materials through cell technology to recycling. The group’s prime objective is to accumulate broader… Read more »

Linear Labs raises $4.5 million to market its electric motor

Electric motor manufacturer Linear Labs has closed a $4.5-million funding round to market its flagship motor, the Hunstable Electric Turbine. The Hunstable Electric Turbine uses multiple rotors. Compared to available permanent magnet motors, Linear Labs’s motor produces twice the torque, three times the power density, two times the output and 10 percent further range, according… Read more »

ION Energy launches BMS for EVs and grid-scale storage

ION Energy, a battery technology company that specializes in battery management and intelligence, has launched the FS-XT, a battery management system targeted at EVs and grid-scale storage systems. To manage the high-voltage batteries needed in EVs, the FS-XT has a modular design based on a master-slave configuration. This allows manufacturers to use the BMS for… Read more »

MIT creates hybrid cathode designed to boost energy capacity of Li batteries

Researchers at the Massachusetts Institute of Technology (MIT) and in China say they’ve developed a new version of the cathode. The researchers describe the cathode as a “hybrid,” since it combines aspects of intercalation-type and conversion-type cathodes to increase gravimetric energy density (per-pound energy output) and volumetric energy density (per-liter energy output). The cathode has… Read more »

Study shows gallium oxide could enable cheaper power electronics

Researchers from the National Renewable Energy Laboratory (NREL) have modeled the wafer cost of gallium oxide (Ga2O3) semiconductors, and determined the cost could be three times lower than that of silicon carbide (SiC). The finding could lead to lower costs for power electronics such as those used in EVs. The researchers created a bottom-up cost model… Read more »

93% of EVs sold in 2018 used permanent magnet traction motors

Research firm Adamas Intelligence has reported that 93 percent of all passenger EVs sold in 2018 used permanent magnet (PM) traction motors, an increase of 1 percent from 2017. PM traction motors use neodymium iron boron (NdFeB) permanent magnets in the rotor, which spin the rotor in response to a rotating magnet field produced in… Read more »

VisIC publishes reference design for its GaN on-board charger

Israel-based VisIC Technologies, a manufacturer of gallium nitride (GaN) power semiconductor devices for the auto, data center and industrial markets, has published a reference design aimed at the EV industry for its on-board charger (OBC) that uses its GaN technology. The 6.7 kW OBC has a volume of 2.3 liters and weighs 4.5 kg, providing… Read more »
