UK consortium to make graphite-based anode for solid-state lithium-ion batteries

A consortium funded by the UK’s government will work toward developing a graphite-based anode to allow solid-state batteries to meet the performance demands required by electric vehicles.

The project will replace metallic lithium anodes in solid-state batteries with consortium partner Talga Technologies’, a subsidiary of Australian firm Talga Resources’, graphite carbon anode Talnode-E product.

The U.S. Department of Energy announced $59 million of funding for 43 projects focused on new and innovative advanced vehicle technology research— with around a third going toward solid-state lithium battery projects.

Universities, vehicle OEMs and private companies are among the thirteen projects that will share around a million dollars each of funding through the Office of Energy Efficiency and Renewable Energy.

Swiss researchers examine solid-state battery secrets

Swiss researchers have lifted the lid on electromechanical processes that take place in solid-state batteries in a move they say could make the technology safer and more efficient for use in electric vehicles.

Researchers at the Paul Scherrer Institute (PSI) used X-ray tomography to observe the batteries “more precisely than ever before” and discovered how fissures in the battery material propagate.

The venture capital arm of Belgium-based battery materials firm Solvay has made an equity investment in US-headquartered next-generation solid-state batteries developer Solid Power.

Solvay Ventures’ move came after Solid Power announced it had generated US$20 million in a Series A investment round, which drew funding from companies including Samsung, Hyundai cradle, Sanoh, and A123 Systems.

Tech firm claims solid-state fast-charge breakthrough

Belgian nanoelectronics and digital tech firm Imec says it has made “an innovative type of solid-state lithium-ion battery” that is set to be a “contender” to power future fast-charging, long-haul vehicles. 

The new battery tech achieved an energy density of 200 Wh/litre at a charging speed of 0,5C (two hours), Imec said.

University of Colorado Boulder spins off solid-state lithium-ion battery with ceramic electrolyte

Tue, 09/24/2013 - 10:54 -- Editor

 

The University of Colorado Boulder (CU-Boulder) has completed a technology transfer agreement for the development and commercialization of a solid-state lithium-ion rechargeable battery with ceramic electrolyte.

The solid-state lithium-ion battery uses a ceramic electrolyte to separate the metal anode from the cathode will be taken further by Solid Power LLC, a CU-Boulder spinoff company founded by Se-Hee Lee and Conrad Stoldt, both associate professors of mechanical engineering.

Lee and Stoldt are attempting to solve lithium-ion thermal runaway concerns by eliminating the liquid electrolyte. Research into the development of solid-state batteries has gone on for a couple of decades, but creating a solid electrolyte that allows ions to pass through it as easily as a liquid electrolyte is difficult.

Instead of using a solid mass of material, Lee and Stoldt created a “composite cathode,” essentially small particles of cathode material held together with solid electrolyte and infused with an additive that increases its electrical conductivity. This configuration allows ions and electrons to move more easily within the cathode.

“The real innovation is an all-solid composite cathode that is based upon an iron-sulfur chemistry that we developed at CU,” Stoldt said. “This new, low-cost chemistry has a capacity that’s nearly 10 times greater than state-of-the-art cathodes.”

Last year, Lee and Stoldt partnered with Douglas Campbell, a small-business and early-stage product development veteran, to spin out Solid Power.

“We’re very excited about the opportunity to achieve commercial success for the all solid-state rechargeable battery,” said Campbell, Solid Power’s president. “We’re actively engaging industrial commercial partners to assist in commercialization and expect to have prototype products ready for in-field testing within 18 to 24 months.”
