Gallium nitride and silicon carbide expected to displace silicon in power electronics

Emerging materials such as gallium nitride (GaN) and silicon carbide (SiC) will eventually displace silicon in power electronic applications, according to a new report from Lux Research, which forecasts that the market for GaN power electronics will reach $1.1 billion, about 5% of the total market, by 2024. While silicon and SiC (SiC-on-SiC) each come… Read more »

Graphene wrapper enhances performance of lithium-sulfur batteries

Lithium-sulfur batteries are of great interest, as they could offer specific energy densities far greater than those of current lithium-ion chemistries. However, current designs are plagued by low efficiency and capacity degradation. A team of researchers from the University of Cambridge and the Beijing Institute of Technology has devised a three-dimensional sandwich-type graphene sheet-sulfur/carbon composite… Read more »

Ioxus announces new line of high-temperature ultracapacitors

New York-based ultracapacitor manufacturer Ioxus has introduced a new line of high-temperature 1250-Farad cells. According to the company, its proprietary Titan technology meets the requirement of automotive customers for ultracaps with a wider operating range that meets both cold and high temperature standards. Ioxus’ newest line of cells functions at temperatures ranging from -40 to… Read more »

DOE offers funding for research into fuel cells, batteries, Schottky diodes

The DOE’s Funding Opportunity Announcement (FOA) for fiscal year 2015, which spans the range of energy technologies, includes a few EV-related topics. Phase I grants of up to $225,000 will be made to small businesses to evaluate the feasibility of ideas that have commercial potential. Topics of interest include: Fuel Cell-Battery Electric Hybrid for Utility… Read more »

Researchers develop dendrite-free lithium films, an important step toward lithium metal anodes

There’s a lot of interest in using lithium metal as an anode material, because of its theoretical high capacity of 3,860 mAh g−1 (around ten times that of the graphite anodes used in typical Li-ion batteries). However, it doesn’t measure up in terms of cycle life and safety requirements, and one reason is the formation of… Read more »

Renault-Nissan sells 200,000 EVs

The Renault-Nissan Alliance has sold its 200,000th EV, highlighting its dominant position in the pure EV market, with a 58% market share. Renault and Nissan EVs have driven approximately 4 billion kilometers, saving 200 million liters of fuel and 450 million kilograms of carbon dioxide. The flagship LEAF is the top-selling plug-in vehicle in the… Read more »

Volkswagen sees “great potential” in solid-state batteries

In a speech at Stanford University last week, Dr Martin Winterkorn, Chairman of the Board of Volkswagen, said that he sees great potential in solid-state batteries, which could boost EV range to as much as 435 miles, representing a volumetric energy density of about 1,000 Wh/l. Replacing the traditional liquid electrolyte with a nonflammable inorganic… Read more »

How to avoid electrical infrastructure upgrades when installing EVSE

With the falling prices, increasing sales and growing mass-market appeal of plug-in vehicles, more and more facility owners are contemplating EV charging amenities for employees, tenants and visitors. EV infrastructure could become a real competitive differentiator by attracting the desirable EV-driving population. In today’s competitive landscape, facility owners can no longer ignore the idea of… Read more »
