The electrolytes in advanced batteries are based on incredibly complicated formulations. If you calculated all of the possible combinations of solvents, salts and additives while trying to find the optimal ratios for just one electrolyte formulation, it would add up to an extraordinary number of possibilities. Because it plays such a critical role in battery… Read more »

Cambridge scientists claim promising lithium-oxygen battery advancements
Cambridge scientists have developed a working demonstrator of a lithium-oxygen battery that is more than 90% efficient, and can be recharged more than 2,000 times. Lithium-oxygen, or lithium-air, has been touted as the ultimate battery technology, because its theoretical energy density is ten times that of lithium-ion solutions. In “Cycling Li-O2 Batteries via LiOH Formation… Read more »
Another Chinese-backed startup announces plans for an electric supercar
New EV companies are cropping up like dendrites on a lithium metal anode. The latest startup to emerge from stealth mode is called NextEV. Like many of the current crop (see Faraday Future, Atieva, Fisker, Leshi), NextEV is backed by Chinese investors, and is not affiliated with a traditional automaker, although it has recruited execs… Read more »

PATHION’s superionic solid-state electrolytes point to more powerful and safer batteries
Solid-state electrolytes are the talk of the town these days. California-based PATHION has been working to commercialize solid electrolytes since its founding in 2012, building on its exclusive license from Los Alamos National Laboratories for a promising material called Lithium-Rich Anti-Perovskite (LiRAP). At the recent Materials Research Conference, PATHION presented two new superionic solid-state electrolytes built upon… Read more »
Beating the polysulfide shuttle to build a solid-state battery approaching theoretical capacity
The latest advance in lithium-sulfur technology comes courtesy of a research team from Samsung and the University of Rome, who have built a solid-state Li-S battery with a capacity (∼1600 mAhg−1) approaching the theoretical value and Coulombic efficiency approaching 99%. In a paper published in the Journal of The Electrochemical Society, the team concludes that… Read more »
SolidEnergy hopes to double EV battery range by 2017
SolidEnergy, an MIT spin-out company commercializing solid electrolyte technology, plans to release a 20 Ah EV battery in 2017, which it says will offer more than two times the range of current Li-ion batteries. The core of SolidEnergy’s technology is a Solid Polymer Ionic Liquid (SPIL) electrolyte, which enables the use of an ultra-thin lithium… Read more »
Researchers announce significant improvement in Li-S battery performance and cycle life
A team from the University of Waterloo in Canada and BASF has developed a way to stabilize cathodes in lithium-sulfur batteries, significantly improving performance and cycle life. Li-S batteries offer high theoretical energy density and low cost, due to the high natural abundance of sulfur. However, the insulating nature of sulfur and lithium sulfides requires… Read more »
