Researchers add compounds to electrolyte to prevent dendrite growth
Those doggone dendrites are the bane of battery boffins working on otherwise promising lithium metal anodes. Now a group of researchers from SLAC, Stanford and MIT have discovered that adding lithium polysulfide and lithium nitrate to an ether-based electrolyte can prevent dendrite growth and minimize electrolyte decomposition. Professor Yi Cui, Professor Yet-Min Chiang (a co-founder… Read more »

LG Chem Power CEO: We’re the Li-ion leader for PEVs because of material science
Q&A with LG Chem Power’s CEO: Dr. Prabhakar Patil on how the company became a Li-ion battery front-runner, the economics of building batteries, and why it spends little energy on what comes after lithium. Among Tier 1 automotive suppliers of lithium-ion cells, LG Chem is off to a clear lead, based on the number of announced… Read more »
Snail shells inspire new battery design
Nanostructured electrodes in Li-ion batteries have several advantages, including shorter distances for charge-carrying particles to travel and a high surface area that provides more active sites for electrochemical reactions to occur. However, working with nanoscale materials is tricky – due to their tiny size, they can be hard to control and hold in place. To… 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 »
