Toyota takes more Asian battery firms along for EV ride

Toyota is teaming up with several Asian battery manufacturers to ensure it has the supplies it needs to ramp up production of electric vehicles, the Japanese car company has confirmed.

Chinese battery and auto makers CATL and BYD are now lined up to work with Toyota—in addition to Japan’s GS Yuasa and Toshiba, Toyota bosses have confirmed.

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.”
