Automakers: Lead-Acid Batteries Are Still Necessary

While lithium-ion is the chemistry of choice for EV batteries, almost every ICE vehicle made today still uses the ancient lead-acid battery technology for its 12-Volt starter battery (Porsche and a couple of other makers of high-performance cars offer lithium-ion starter batteries). Auto OEMs and battery providers want to preserve […]

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 […]

Researchers Develop Dendrite-Free Lithium Films, an Important Step Toward Lithium Metal Anodes

There’s a lot of interest in using lithium metal as an anode material, because of its theoretical high capacity of 3,860 mAh g−1 (around ten times that of the graphite anodes used in typical Li-ion batteries). However, it doesn’t measure up in terms of cycle life and safety requirements, and one […]
