Sakti could mass produce next generation solid state battery for around $100 per kwh

Sakti3, a startup with $15 million of investment by billionaire James Dyson and $50 million from other sources, claims to have already generated twice the energy density of the most advanced lithium ion battery on the market today with a new solid state battery.

Toyota has a battery roadmap showing power and energy densities expected for selected battery technologies suggests that all solid-state batteries are an important step in the evolution of batteries for electric vehicles, but are not the ultimate solution.

Sakti3, Inc. (sakti3.com) announced that in mid-2014 that they had produced a battery cell on fully scalable equipment with over 1100 Watt hours per liter (Wh per l) in volumetric energy density. This translates to more than double the usage time in a wearable device like a smartwatch, from 3.5 h to more than 9 h. It also translates to almost double the range in an EV like the Tesla Model S, from 265 mi to 480 mi.

Sakti3 reports that it demonstrated over 1000 Wh per l in 2012, and has since moved to a pilot tool, using all scalable materials and equipment. The technology development was guided by mathematical simulations, starting with materials, and continuing to full scale plant layout to avoid any high cost materials, equipment or processes.

”Our [Sakti’s] target is to achieve mass production of cells at ~$100 per kWh,” said Dr. Ann Marie Sastry, CEO of Sakti3. “Our key patents on the technology have been issued, we are up and running on larger tooling, and can now speed up processing. Our first market will be consumer electronics, and after that, we’ll move to other sectors.”
