Conventional wisdom has it that lithium-ion batteries are the state of the art, and that nickel-metal hydride chemistry, which is used in most conventional hybrids (some of the newer Prius models now use Li-ion), is pretty much obsolete. However, scientists at BASF believe that NiMH technology still has much to offer. According to MIT Technology Review, the… 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 »
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 »
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 »
Scientists discover the secret of aging (of lithium-ion batteries)
Aging is an inescapable fact of life, not only for people, but for batteries as well. Researchers at the Helmholtz Center Berlin (HZB) recently identified a major reason why Li-ion batteries degrade with time. They have directly observed atomic rearrangements occurring in cathode materials during charge and discharge processes, which lead to the breakdown of the… Read more »
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 »
Japanese mining firm triples lithium nickel oxide production
“Just one word, young man: lithium!” As EV production ramps up, companies at all points in the supply line for the lightest metal are getting ready for new levels of demand, from Tesla CEO Elon Musk, who recently warned that a “truly gargantuan battery factory” will soon be needed, to Panasonic, which is investing $200… Read more »
Navigant Research releases Leaderboard Report on lithium-ion battery manufacturers
In a new report, Navigant Research profiles 11 Li-ion battery vendors that are active in the EV market, and rates them on 13 criteria, including systems integration, safety engineering, chemistry performance, geographic reach, manufacturing and product performance, pricing, and overall corporate financial health. According to Navigant, “Li-ion batteries have won the race to be the chemistry… Read more »
Toyota increases production of lithium-ion batteries
Toyota and Panasonic plan to build a new $194-million production line to produce Li-ion batteries, with a capacity of 200,000 units per year.
OXIS Energy bets on lithium-sulfur
Though it may have a stinky reputation, sulfur could set EVs on the path to total ICE replacement if energy-dense, low-weight lithium-sulfur batteries become the norm. British-based OXIS Energy is banking its business on it. If American clean energy industries are to take full advantage of the emerging lithium-sulfur (Li-S) battery chemistry, they just may… Read more »
