Berkeley Lab researchers get to the root of the lithium anode problem

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 »

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 »

New X-ray microscopy technique reveals the secret life of batteries

In pursuit of their quest for more capable batteries, scientists are searching for better ways to observe battery particles as they charge and discharge in real time. A new technique developed at Berkeley Lab’s Advanced Light Source is providing researchers with nanoscale images of the electrochemical reactions that make lithium-ion batteries do their thing. In… Read more »

Materials Project releases trove of battery-related materials data to the public

The Materials Project, a searchable database of material properties, was launched in 2011 by the DOE’s Office of Science. It uses supercomputers to calculate the properties of materials based on first-principles quantum-mechanical frameworks. The Materials Project is designed to save researchers time by predicting the properties of materials, eliminating the need to synthesize them in… Read more »

New electrolyte for solid-state batteries combines polymer and glass

Scientists at the DOE’s Lawrence Berkeley National Laboratory have developed a novel electrolyte that addresses many of the problems of solid electrolytes by combining the two primary types – polymer and glass. There are two kinds of solid electrolytes – polymer and glass or ceramic – and each has its own set of challenges. Polymer… Read more »
