Pacific Northwest National Laboratory (PNNL) researchers have developed a nickel-based metal organic framework to hold onto polysulfide molecules in the cathodes of lithium-sulfur batteries and extend the batteries’ life spans. A promising new battery chemistry is the lithium-sulfur battery, which can hold as much as four times more energy in a given mass than typical [...]

Researchers at the USC Viterbi School of Engineering have developed a cheap, high-performing silicon anode and sulfur-based cathode for lithium-ion batteries.  The new anode is reported to be a cost-effective (and therefore commercially viable) silicon anode nearly three times more powerful and longer lasting than a typical commercial anode. Using silicon for the anode is [...]

Nobuyuki Imanishi, Ph.D. at Mie University in Japan reports progress on a “breathing” battery that has the potential to one day replace the lithium-ion technology of today’s electric vehicles. The main difference between lithium-ion and lithium-air batteries is that the latter replaces the traditional cathode, a key battery component involved in the flow of electric [...]

ETH Zürich researchers have succeeded in producing uniform antimony nanocrystals and testing them as components of laboratory batteries.  The nanocrystals are able to store a large number of both lithium and sodium ions, operate at high rates and may eventually be used as alternative anode materials in future high energy-density batteries. The materials hunt is [...]

Watching Batteries Work

February 20, 2014 | 1 Comment

Researchers at the Oak Ridge National Laboratory (ORNL) can image and measure electrochemical processes in batteries in real time and at nanoscale resolution.  Using a new microscopy method scientists watch a miniature electrochemical liquid cell that is placed in a transmission electron microscope to study an enigmatic phenomenon in lithium-ion batteries called the solid electrolyte [...]
