2 Ceramic Electrolyte Solid-State Battery Projects Get $6.6 Million From ARPA-E

December 7th, 2015 by  

Originally published on EV Obsession.

A total of $6.6 million in new funding has been awarded by ARPA-E to two projects currently working to develop manufacturing techniques for ceramic electrolytes for solid-state electric vehicle batteries, as part of a new 2015 OPEN funding round. The new round is seeing $125 million awarded to 41 different projects.

The $6.6 million will be divided thusly: $3.5 million going to a consortium headed by the University of Michigan, and $3.1 million going to Corning Incorporated.

For some basic background here, solid-state lithium batteries are a promising technology owing to the fact that energy density could potentially be doubled from that of the lithium-ion batteries currently in use. Another possible advantage is the elimination of the use of conventional flammable electrolytes.

Here’s a brief overview of the two projects via Green Car Congress:

In a project labeled “Transitioning Advanced Ceramic Electrolytes into Manufacturable Solid-State EV Batteries,” researchers at the University of Michigan and partners will develop new electrode structures and manufacturing techniques to incorporate Lithium (Li)-conducting ceramic electrolytes into solid-state batteries. The U-M project is led by Jeff Sakamoto, an associate professor of mechanical engineering, who is also affiliated with with U-M’s Energy Institute. Like many energy storage researchers, Sakamoto has been exploring solid-state batteries, which don’t use a liquid electrolyte. Liquid electrolyte contributes to many of the lithium-ion battery’s limitations. His APRA-E proposal aims for an inexpensive, highly efficient solid-state battery that is tough and safe enough to power a vehicle.

In Corning’s project, “Roll-to-Roll Processing Ceramic Battery Electrolyte,” researchers there will develop roll-to-roll manufacturing techniques to produce thin ceramic electrolytes for solid-state batteries. The technology developed in this project is intended to enable solid-state batteries to be produced economically and at high volumes.

As always with battery research… Don’t hold your breath. Nonetheless, this seems worth taking note of.

    The use of ceramic materials in Electric Vehicles are limited by their brittleness, and that is why Solid Oxides Fuel Cells are not recommended for EV’s and mobile machineries that are prone to shocks and shaking.

    So can we say that one of their breakthroughs involved circumventing around the ceramic material brittleness by making the solid state ceramic electrolytes thin and pliable?

      What about solid oxide fuel cells where earthquakes happen, such as California, Japan, and Nepal?

        It should be easy to simulate the earthquakes to observe the effects on SO fuel cells to determine that. SO fuel cells have to be heated to 700 Centigrade to operate so they are not useful for most cars as cars are only utilised on average 5% of the day. They might be okay for long distance trains.

      In reading between the lines of previous articles, I surmised that Satki3 (now Dyson’s company) was using some form of plating to construct the cells. As you indicated, that may make them more pliable and sandwiched between the cathode and anode, maybe they could survive real world use.
