Scientists at the DOE’s Pacific Northwest National Lab have uncovered a “root” cause of the growth of needle-like structures – known as dendrites and whiskers – that plague lithium batteries and can cause short circuit, failure, and even fire. Dendrites are tiny, rigid tree-like structures that can grow inside a lithium battery. Their needle-like projections… Read more »

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 »
Imec doubles energy density of its Li-metal batteries to 400 Wh/liter
Imec, a Belgian research firm focused on nanoelectronics, has unveiled a solid-state Li-metal battery cell with an energy density of 400 Wh/liter at a charging speed of 0.5C (2 hours). As part of a larger engineering roadmap for solid-state batteries, imec aims to surpass wet Li-ion battery performance and reach 1,000 Wh/L at 2-3C by… 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.

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 »
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 »
