Samsung invests in Solid-state battery-maker Seeo, sets sights on 400 Wh/kg

Seeo, a developer of lithium polymer batteries, has closed its largest funding round to date, adding Samsung Ventures to its list of investors. The company will use the new capital to accelerate the commercialization of its high-energy-density batteries. Seeo’s patented DryLyte solid polymer electrolyte is non-flammable and non-volatile, and delivers high energy density. Currently, Seeo… Read more »

Volkswagen buys piece of solid-state battery startup

Volkswagen has bought a five-percent stake in battery startup QuantumScape. Confidential sources told Bloomberg that the Volkswagen Group plans to complete tests of QuantumScape’s technology by mid-2015, and is considering using it in VW, Porsche and Audi vehicles. Closely-held QuantumScape, founded in 2010 by former Stanford University researchers, is working on solid-state batteries, which it… Read more »

Volkswagen sees “great potential” in solid-state batteries

In a speech at Stanford University last week, Dr Martin Winterkorn, Chairman of the Board of Volkswagen, said that he sees great potential in solid-state batteries, which could boost EV range to as much as 435 miles, representing a volumetric energy density of about 1,000 Wh/l. Replacing the traditional liquid electrolyte with a nonflammable inorganic… Read more »

ORNL team demonstrates high-voltage solid-state battery with impressive cycle life

Researchers at the Oak Ridge National Laboratory have demonstrated a solid-state high-voltage (5 V) lithium battery with an extremely long cycle life (10,000 cycles) and high Coulombic efficiency (99.98%). The solid electrolyte enables the use of high-voltage cathodes and lithium anodes with minimal side reactions. The energy stored in a battery of a given size… Read more »

Sakti3 demonstrates impressive energy density with solid-state battery cells

For a few years, battery insiders have been talking about a startup company called Sakti3. The University of Michigan spin-out has received millions in funding from backers including Khosla Ventures and GM Ventures. Until recently, the company has been pretty secretive, but this week CEO Ann Marie Sastry told Scientific American that the company’s prototype… Read more »

Toyota researchers develop all-solid-state Li-ion batteries

As Toyota plans to bring a fuel cell vehicle to market in 2015, its researchers continue to work on next-generation battery technologies. In a presentation at the International Meeting on Lithium Batteries in Como, Italy, Dr. Hideki Iba from Toyota’s Battery Research Division and Dr. Chihiro Yada from Toyota Motor Europe’s Advanced Technology Group noted… Read more »

University of Colorado researchers to commercialize new solid-state battery

The University of Colorado Boulder (CU) has signed an agreement with Solid Power LLC, a spin-off company, to develop and commercialize a solid-state battery technology that has the potential to greatly improve EV range. Solid Power, founded by Se-Hee Lee and Conrad Stoldt, both associate professors of mechanical engineering, was recently awarded a $3.4 million… Read more »

New report: Solid-state batteries will rule by 2030, driven by consumer electronics

A report from technology advisory firm Lux Research predicts that new battery technologies will become strong competitors with existing lithium-ion technology by 2020, and that solid-state batteries will surpass Li-ion by 2030. However, consumer electronics, not electric vehicles, will be the market driving the advances. “While much of the motivation for next-generation batteries – whether… Read more »

Lyten exceeds 90% yield in lithium-sulfur battery production

Lyten, a supermaterials application company, reports that its automated battery production line consistently exceeds 90% yield, confirming the viability of manufacturing its lithium-sulfur battery using a sulfur cathode and lithium metal anode. Converting lithium-ion equipment to produce lithium-sulfur batteries in Lyten’s pilot facility required six weeks. Lyten’s lithium-sulfur battery chemistry utilizes no N-methyl-2-pyrrolidone (NMP) in… Read more »

Toray develops ion-conductive polymer membrane for batteries

Toray Industries, a Japanese performance chemical manufacturer, has developed an ion-conductive polymer membrane that it says delivers 10 times the ion conductivity of its predecessors. The new polymer membranes offer ion conductivity through hopping conduction. This mechanism enables lithium ions to traverse between interacting sites within polymer membranes, jumping across sites. The membranes remain non-porous…. Read more »
