In the quest for higher energy density, the use of lithium metal anodes would seem to be a promising approach, if it weren’t for those doggone dendrites. Dendrites are microscopic fibers of lithium, which sprout, tree-like, from the surface of the lithium electrode and spread through the electrolyte until they reach the other electrode, possibly… Read more »

GE and Berkeley researchers hint at new water-based battery
It sounds like an intriguing idea: a new type of battery that uses water-based solutions of inorganic chemicals that can supply high energy density by ferrying more than one electron at a time. Scientists at GE Global Research and Lawrence Berkeley National Laboratory are working on such a system, which they call the a “flow”… Read more »
Updated OpenADR communications standard helps utilities manage renewables and EV charging
The OpenADR Alliance has launched a new version of its OpenADR communications standard. OpenADR 3.0 is designed to help utilities, operators, aggregators and customers manage the growing range of distributed energy resources (DERs), which includes renewable generation, stationary energy storage, EV batteries and bidirectional EV charging stations. As an open standard, OpenADR is designed to… Read more »
Researchers say electric ships could economically serve 40% of today’s sea routes
Oceangoing ships, most of which are powered by heavy fuel oil, produce substantial amounts of CO2 and nitrogen oxide emissions. However, shipping companies are unlikely to begin electrifying them until the economic case for doing so becomes clearer. A new study from the University of California, Berkeley and Lawrence Berkeley National Laboratory indicates that nearly… Read more »
New study says commercial truck electrification is within reach
It’s been a long haul for electric trucks—pilots have been going on for over a decade, but fleet operators are just beginning to put in serious orders. Battery costs are often cited as a barrier to faster adoption, but a new analysis concludes that a lack of appropriate policies around adoption incentives, charging infrastructure, and… 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 »
Vehicle-to-grid project reveals challenges of the early days
Los Angeles Air Force Base became the first federal facility to replace its entire general-purpose fleet with plug-in vehicles in a two-year V2G research project Vehicle-to-grid (V2G) is a technical and policy-based effort to optimize the way EVs interact with the electrical grid. V2G developers view EVs as “resources” within an electrical network. In V2G… Read more »
DOE awards $6 million to first crop of Battery500 Seedlings
The Battery500 consortium, led by the DOE’s Pacific Northwest National Laboratory (PNNL), intends to build a battery pack with a specific energy of 500 Wh/kg, which would more than double the 170-200 Wh/kg per kilogram in today’s typical EV battery. Part of the initiative is the “Seedling” program, which identifies new and risky battery research… Read more »
DOE awarding $19 million to 22 advanced vehicle technologies projects
The DOE is awarding $19.4 million to 22 new cost-shared research projects in the fields of advanced batteries, lightweight materials, emission control, and energy-efficient mobility systems. Fifteen of these are Phase 1 Battery Seedling projects, aimed at battery materials and approaches that complement the Battery500 Consortium’s research. Promising Phase 1 awardees will be competitively weeded… Read more »
California Energy Commission awards $36 million for clean transportation projects
The California Energy Commission has awarded more than $36 million in grants for various clean energy transportation projects. The South Coast Air Quality Management District and Long Beach Harbor Department received $10 million each and the Los Angeles Harbor Department received $4.5 million to conduct field demonstrations of medium- and heavy-duty vehicles and cargo handling… Read more »
