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 »
WEBINAR: Modeling Capacity Fade of Lithium-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 »
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 »
Chinese and Chilean lithium giants make $4-billion stock purchase deal
China-based Tianqi Lithium has purchased a substantial number of shares in Sociedad Química y Minera de Chile (SQM), which claims to be the world’s largest lithium producer, in a deal worth approximately $4.07 billion. Chinese companies have been on a lithium buying spree recently, as prices of the “white gold” steadily climb. Tianqi and SQM… 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 »
UK lithium sulfur battery firm OXIS secures funding to expand to Brazil
UK battery technology company OXIS Energy will receive a £3.7-million investment from the Brazilian private equity fund Aerotec, paving the way for OXIS to open a subsidiary in Brazil. The agreement provides for a Brazilian team to be trained at OXIS Energy’s headquarters in Oxford, as well as the creation of an R&D center in… 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 »
Increasing concentration of LiFSI salt suppresses dendrite formation
Lithium metal is considered an ideal anode material due to its exceptional charge and storage capability, but it has a tragic flaw: root-like growths called dendrites, which can lead to short-circuiting and spontaneous combustion. Now, researchers at the University of Maryland (UMD) have announced a breakthrough in their quest to solve the dendrite issue. In… Read more »
