Battery researchers around the world are working on lithium metal electrodes, which have the potential to greatly increase energy density. But the drawback to lithium in this form comes in the form of dendrites, root-like lithium deposits that form on the metal surface and can harm performance and even lead to short circuits. Now a… Read more »

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 »
Real-time images of lithium dendrite structures could lead to better batteries
Scientists at the DOE’s Oak Ridge National Laboratory have captured the first real-time nanoscale images of lithium dendrite structures in lithium-ion batteries. The ORNL team is confident that its research, published in Nano Letters, will be of great benefit to scientists who are experimenting with different ways to tackle the dendrite problem. Dendrites form when… Read more »
Kevlar-based nanocomposite foils dendrites for bulletproof batteries
Those doggone dendrites are a bane of battery builders. These pesky fern-like growths can form on the surfaces of anodes during cycling, reducing battery life or even causing a catastrophic short circuit – this is how the battery fires on the Boeing 787 are thought to have started. A team of researchers from the University… Read more »
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 reason is the formation of… Read more »
Zeta Energy makes a breakthrough in lithium-sulfur battery technology
Cheap, abundant and sustainable. Sulfur may not be the most glamorous of elements—some may associate it with rotten eggs, stinky well water, or even the devil, as invoked in a country preacher’s fire-and-brimstone sermon. But as a component of an EV battery cathode, sulfur has a lot to offer. The yellow stuff is lighter and… Read more »
Korean researchers develop artificial polymer nanolayers to improve zinc battery stability
Researchers at Chungnam National University in South Korea have developed a new zinc-bonded polyacrylic acid (ZHP) layer that prevents dendrite growth and stabilizes the anode in zinc-ion batteries. Aqueous zinc-ion batteries are gaining attention as a safer and more affordable alternative to lithium-ion batteries. However, previous protective coatings developed to prevent side reactions and sharp… Read more »
Natrion takes orders for US-made active battery separator
US-based battery technology company Natrion has begun accepting pre-orders for its first-generation flagship separator, which is designed to boost energy density, reduce costs and offer manufacturers a source of US-made products. The Gen-1 active separator, which uses Natrion’s lithium solid ionic composite (LISIC) technology, mitigates common Li-ion battery cell degradation processes. It offers enhanced cell… Read more »
How to optimize battery development and production with CT technology
Sponsored by Lumafield. Traditional battery testing methods often fall short in detecting internal defects or optimizing complex designs. CT scanning addresses these challenges by providing non-destructive, detailed internal visualizations of battery cells, enabling engineers to find misalignments, folds, tears, and other internal defects without disassembling the cell. This capability accelerates development, enhances reliability, and supports… Read more »
24M Technologies reports battery separator innovations that can reduce battery fires
Lithium-ion battery technology developer 24M has released new testing data for its Impervio battery separator. The testing was related to the issue of battery-fire risk in EVs, energy storage systems and consumer applications. The company’s Impervio battery separator was designed to reduce the risk of overcharging that can cause metallic dendrite formation and internal shorts,… Read more »
