DOE awards $1.2 million to Wildcat Discovery for improved solid-state batteries
The US DOE has awarded $1,223,833 to Wildcat Discovery Technologies, a company that uses high-throughput methods to develop next-generation battery materials, to develop materials for an all-solid-state battery. Solid-state batteries will allow for higher energy densities and better safety performance, according to Wildcat, which will use the money to explore the development of a composite… Read more »
Free Webinar: Modeling capacity fade of Li-ion cells
If you want to learn about creating a mathematical model of a lithium-ion cell, then tune into this webinar featuring guest speaker Ralph White of the University of South Carolina. This presentation will focus on the development of the equations used to produce a physics-based model of a lithium-ion cell that includes capacity fade due… Read more »
New conductor could lead to high energy all-solid-state batteries
Researchers have developed a conductor material that could lead to all-solid-state batteries with the highest energy density achieved to date. Current batteries employ organic liquid electrolytes that are prone to leakage, flammability, and limited energy density, issues which could be eliminated with all-solid-state batteries. The researchers developed a complex lithium superionic conductor that showed high… Read more »
Lavle working on solid electrolyte battery ESS for marine market
Lavle, a Washington-based marine battery company, says it’s developing a large-scale solid electrolyte battery (SEB) energy storage system (ESS) for the marine market. The Lavle marine solution will utilize SEB cells supplied by its Japanese joint venture partner, 3DOM, and engineering expertise from its American joint venture partner, Ockerman Automation. The 3DOM SEB cells use… Read more »
Rice University adds red phosphorus to separators to foil dendrites
Rice University scientists have found that adding a layer of red phosphorus to separators in lithium metal batteries can signal when damaging dendrites threaten to create a short circuit. Rice University chemist James Tour made lithium metal test cells with a coat of red phosphorus on the separator, which keeps the anode and cathode electrodes… Read more »
University of Michigan researchers develop non-combustible, non-degrading ceramic electrolyte
Scientists at the University of Michigan have developed a solid-state electrolyte which they claim is non-combustible (which is good, because it’s heated to over 1,800° F during manufacturing!) and not vulnerable to dendrite formation due to a stabilizing ceramic layer. The electrolyte has special properties that allow for increased capacities and faster charging rates as well. Current… Read more »
Researchers achieve extended cycle life using molybdenum compound as protective anode layer in Li-S batteries
Researchers at The University of Texas at Dallas have used two-dimensional molybdenum disulfide (MoS2) as a protective layer for Li-metal anodes to greatly improve the performance of Li-S batteries. In “2D MoS2 as an efficient protective layer for lithium metal anodes in high-performance Li–S batteries,” published in Nature Nanotechnology , the researchers report that such a use of MoS2 results in… Read more »
Self-healing anode eliminates dendrite buildup
Researchers at Rensselaer Polytechnic Institute (RPI) have demonstrated a “self-healing” lithium-metal anode that can eliminate dendrite buildup. Researchers are looking for ways to replace graphite anodes with lithium metal in order to boost energy density. However (as regular Charged readers know), lithium metal anodes are plagued by the buildup of dendrites, branchlike protrusions that can grow… Read more »
Garnet ceramic electrolyte helps block dendrite formation
Researchers at the University of Maryland have developed a new template that they hope will enable a safer alternative to liquid electrolytes, which have several drawbacks, including flammability, leakage and dendrite formation in the electrodes. In “Lithium-ion conductive ceramic textile: A new architecture for flexible solid-state lithium metal batteries,” published in Materials Today, UMD researchers… Read more »
