Carbon nanotubes help make lithium metal batteries more durable
Carbon nanotubes could make high-powered, fast-charging lithium metal batteries an alternative to lithium-ion batteries, according to new research from Rice University. In a paper published this month in the journal Advanced Materials, the researchers show how a carbon nanotube film can be used to keep batteries safe from dendrites, spear-like protrusions that naturally form on… Read more »
New insight into lithium metal plating could enable faster charging times
Ranges are getting longer, battery capacities are getting larger, and the pressure is on to find ways to make charging faster. Unfortunately, reducing charging time by increasing charging current can have a negative effect on battery lifetime and safety. One reason for this is a phenomenon called lithium plating. “The rate at which lithium ions… Read more »
Waterloo team develops low-cost approach to stabilize lithium metal anodes
Researchers at the University of Waterloo in Canada have developed a way to stabilize lithium metal electrodes by forming a single-ion-conducting and stable protective surface layer in vivo. In “An In Vivo Formed Solid Electrolyte Surface Layer Enables Stable Plating of Li Metal,” published in the journal Joule, Quan Pang, Xiao Liang and colleagues explain how they… Read more »
alpha-En wins grant to commercialize lithium metal anodes
New York-based alpha-En has won an award of $750,000 from the DOE’s Office of Technology Transition Technology Commercialization Fund. The funding will be used to commercialize Argonne National Laboratory’s proprietary highly conductive solid-state electrolyte coating for alpha-En’s lithium metal anodes. alpha-En says its lithium metal is purer than what is currently available on the market,… Read more »
Nanoscale measurement of lithium metal could lead to suppressing dendrite formation
Lithium metal, which can store more energy than carbon, would seem to be an ideal anode material, except for one serious flaw: dendrites, tiny needle-like branching structures that can grow through the battery, eventually causing a short circuit. Now, a joint team of researchers from Caltech and Carnegie Mellon University has measured the strength of… Read more »
Canada bans shipments of lithium metal batteries on passenger flights
The Canadian Transport Ministry has officially banned the transport of lithium metal batteries as cargo on passenger flights, bringing its regulations into line with a ban adopted by the International Civil Aviation Organization in 2014 (the US has already instituted a ban). The new rule does not apply to lithium-ion batteries, or to lithium metal… 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 »
Lyten to acquire lithium-metal battery manufacturing assets from Cuberg
San Jose-headquartered Lyten, a manufacturer of advanced materials and sulfur-lithium batteries, plans to acquire manufacturing assets from San Leandro-headquartered Cuberg, including its lithium-metal battery manufacturing facility and cell-making equipment. Lyten plans to convert the facility to lithium-sulfur battery production and to invest up to $20 million in 2025 to expand its full Bay Area production… Read more »
EMP Metals conducts lithium extraction pilot with Koch and Saltworks
EMP Metals, a Canadian lithium exploration and development company, is conducting a direct lithium extraction (DLE) pilot at its facility in Saskatchewan. The facility has a DLE pilot skid from UK engineering technology firm Koch Technology Solutions (KTS), while Canadian lithium refining systems supplier Saltworks Technologies provided pre- and post-DLE systems and concentrate, refine and… Read more »
