Governments around the world are pursuing policies to speed up EV adoption, but most are piecemeal—a purchase incentive here, an investment in EVSE there. California and the UK are among the few entities that are developing comprehensive plans to electrify all forms of transport. The Centennial State is moving closer to that ideal, and is… Read more »

London firms partner to convert 1,000 storage units to EV charging hubs
The plight of urban dwellers who have no assigned parking spaces is emerging as the next big roadblock to faster EV adoption. In London, an estimated 78% of households have no private parking spaces, and Mayor Sadiq Khan has set a target of deploying 50,000 charging points in the city by 2025. With encouragement from… Read more »
Promising lithium-sulfur active battery material made with low-cost liquid phase process
Scientists at the Toyohashi University of Technology have made an active sulfur material and carbon nanofiber (CNF) composite using a low-cost liquid phase process. Their paper, published in the American Chemical Society’s ACS Applied Energy Materials, claims that all-solid-state lithium-sulfur batteries using a sulfur-CNF composite material show higher discharge capacity and better cycle stability than… Read more »
Tesla surprises with Q1 profit, has “record backlog” of orders
Tesla has extended its earnings streak, posting a surprise profit in the first quarter, typically a tough one for automakers. The company reported record levels of production, and says its vehicle order backlog is the highest it’s ever been. “Q1 2020 was the first time in our history that we achieved a positive GAAP net… Read more »
Cree’s 650 V SiC MOSFETs designed for onboard EV charging
Cree recently released the Wolfspeed 650 V silicon carbide MOSFET series, designed for the next generation of onboard EV chargers, data centers and renewable energy systems. “Cree is leading the global transition from silicon to silicon carbide, and our new 650 V MOSFET family is the next step in delivering a high-powered solution to a… Read more »
BMW reveals details of hydrogen fuel cell powertrain system
Different automakers have different visions of the low-emissions future, to say the least. Just a few days after the Volkswagen Group released an article explaining why it has abandoned hydrogen fuel cells in favor of battery-electric powertrains, BMW has “reaffirmed its ongoing commitment to hydrogen fuel cell powertrain system technology.” Unlike VW, BMW is leaving… Read more »
Researchers track lithium ions in a fast-charging battery
A team of scientists led by the DOE’s Brookhaven National Laboratory and Lawrence Berkeley National Laboratory has captured in real time how lithium ions move in lithium titanate (LTO), a fast-charging battery electrode material made of lithium, titanium and oxygen. They discovered that distorted arrangements of lithium and surrounding atoms in LTO “intermediates” (structures of… Read more »
Samsung researchers describe all-solid-state battery with silver-carbon composite layer
Researchers from the Samsung Advanced Institute of Technology (SAIT) and the Samsung R&D Institute Japan (SRJ) have published a study on high-performance, long-lasting all-solid-state batteries in the journal Nature Energy. Compared to lithium-ion batteries, which employ volatile liquid electrolytes, all-solid-state batteries use non-volatile solid electrolytes that support greater energy density. However, their lithium metal anodes… Read more »
LiTDI: An electrolyte additive for extended battery life and fast charging
Sponsored by Arkema With the electric vehicle market driving a surge in demand for lithium-ion batteries, research is intensifying to develop new electrolytes that not only ensure battery performance, lifetime, and safety, but also enable high-energy anode materials, such as silicon, and cathode materials, such as NMC 811. High purity electrolyte components are crucial to… Read more »
How to maximize safety in advanced battery systems
By Markus Beck, Sensata Technologies In advanced battery systems, the quality of the power electronics helps determine the quality of the final product, its level of functionality, and its reliability. This is emphasized in the latest battery power management and charging systems that use wide-bandgap semiconductors and improved power topologies. In such advanced electronics, if… Read more »
