People from Satki3 team are working under new project that could make ≥100-mile electric cars affordable.
"High-performance, sold-state lithium-ion batteries should be able to get down to $100 per kWh" - engineers from Sakti3 said.
The devices are manufactured using a unique combination of existing, scaled platforms that offer a low CAPEX-to-revenue path to large-scale production, in a single, integrated, manufacturing line. The materials, device designs and manufacturing methodologies were selected and optimized through use of advanced computational modeling, and lockstep, small-scale prototyping. Sakti’s unique design capability has enabled the company to secure IP across multiple areas of energy storage technology, including materials, processes, system architectures and controls, and fields of use for solid state battery technology. Sakti is now methodically scaling prototypes in pilot production.
Of course, “could” and "should" are the key words right now, and no timeframe has been estimated, as far as I have seen. However, Sakti3 apparently has a lot going for it and support from some industry insiders.
A few words about the company
Sakti’s battery technology was recognized with IHS CERAWeek’s Energy Innovation Pioneer Award (2014), by MIT’s Technology Review Magazine as one of the Top 50 Most Innovative Companies (2012) and World’s Top Ten, representing the “energy” category (2011). The senior team has over 100 years’ collective experience in research, manufacturing, and leadership. The company is a spinout of the University of Michigan, where its founding team created laboratories, published over 80 papers on battery technology, and demonstrated its first early prototypes. Financed by the world’s top cleantech fund, Khosla Ventures, and the world’s largest automotive investor, General Motors Ventures, the company has been recognized for its innovative approaches in Inc., Time, Automotive Engineering, the New York Times, Washington Post, NPR and other media.
Tesla's leadership could be over soon
Tesla’s batteries reportedly cost it $200-300 per kWh, and they are said to be the best bargain on the market. Of course, Tesla and partner Panasonic are supposed to be getting their battery costs down on their own, especially through the scaling up of production at their planned Gigafactory, so let’s not get into implications for Tesla here. But if Sakti3 was able to get manufacturing going at $100 kWh within a few years (a big “if” in the world of battery startups), and Nissan was to use these batteries in its LEAF or some younger LEAF sibling, that could mean an electric car with over 250 miles of range for under $30,000 (the average new car in the US and Europe goes for over $32,000)… if we assume $300 per kWh for Nissan’s current batteries (Nissan’s current battery costs may very well be higher).
At such a point, the electric car would be cleaner; for many people, cheaper; greener; not dependent on foreign oil; more convenient to recharge (by a landslide - just plug in once in awhile before going to bed); and more fun to drive.
Of course, another route (and a smarter route according to my eyes) would be to double the LEAF’s range while also cutting the price by several thousand dollars (again). That would be killer, imho. Of course, one model alone wouldn’t bring an EV revolution, but the battery would surely be available to multiple automakers.
Also, for the record, GM Ventures invested in Sakti3 back in 2010, after partnering up more than a year earlier, so this is far enough along that it is a technology that GM is putting some money on.
