The latest battery breakthrough comes from Nanyang Technological University (NTU Singapore), where researchers have developed a lithium-ion battery that they say can be recharged up to 70 per cent in only two minutes, and can endure more than 10,000 charging cycles. NTU Singapore’s scientists replaced the traditional graphite anode with a new gel material made… Read more »

Fraunhofer Institute presents November workshop on lithium-sulfur batteries
The Fraunhofer Institute will hold its third annual workshop on lithium-sulfur batteries in Dresden, Germany, on November 12 and 13. Lithium-sulfur is a leading contender for the battery chemistry of the future, and Fraunhofer believes that novel materials such as nanostructured carbon/sulfur composite cathodes, solid electrolytes and alloy-based anodes will significantly enhance performance. Dr Oliver… Read more »
New imaging technique gives researchers an unprecedented look at the inner workings of batteries
Scientists around the world are testing new ways to look inside lithium-ion batteries to gain a better understanding of what happens during charging and discharging. A team of chemists and engineers at Ohio State University claims to be the first to use Neutron Depth Profiling (NDP) to track the flow of lithium ions into and… Read more »
A closer look at how batteries fail
A lot of research has been done to improve lithium-ion battery safety, cycle life and power output over a range of high and low temperatures, yet understanding the fundamental processes and degradation mechanisms in Li-ion batteries remains a challenge. To understand the degradation processes of lithium-ion batteries, it is important to understand how they operate…. Read more »
Stanford team develops stable lithium anode
Are the knights of nanotechnology closing in on the Grail at last? A team of researchers at Stanford University claim that they are, and have chronicled their deeds in the journal Nature Nanotechnology. The valiant engineers report that they have designed a pure lithium anode. “Of all the materials that one might use in an… Read more »
For a better battery, hit the beach!
Who knew? The miracle material that could enable a game-changing battery breakthrough is (drumroll, please)…beach sand. Researchers at the University of California Riverside have created a lithium-ion battery that outperforms the current industry standard by three times, using a nanoscale silicon dioxide anode. “This is the holy grail – a low cost, non-toxic, environmentally friendly… Read more »
DOE-supported research projects seek to commercialize silicon-based anodes
The DOE is supporting six applied battery research projects, with the objective of developing cells that provide energy density of more than 200 Wh/kg, along with long cycle life and excellent abuse tolerance. All six projects are using some form of silicon-based material for the anode. A team led by the Argonne National Laboratory is… Read more »
Swedish researchers: Carbon fiber can serve as both body panel and battery
It’s one of the dilemmas of EV design: It’s imperative to keep a vehicle’s weight as low as possible, but the most critical component – the battery – is necessarily quite heavy (and bulky). A little outside-the-box thinking yields an elegant solution – make the box the battery. In other words, design a battery material… Read more »
Wildcat’s new copper fluoride cathode material offers 2.5x more capacity than today’s battery tech
The current generation of lithium-ion battery materials is quickly approaching its theoretical limit. In commercial layered oxide cathodes, like the popular nickel-manganese-cobalt (NMC), there is only one lithium ion for every metal. So, the most energy you could possibly store with those materials is one full lithium in and out, or about 300 mAh per… Read more »
Silicon rally: EnerG2’s new silicon battery anode material
It seems that every time the hottest new smartphone or tablet comes out, one of the biggest points of contention among users is its battery life. The demands put on the batteries run them down faster than users would like, and the OEMs can’t simply increase the batteries’ size while still hitting their targets for… Read more »
