Technological change often begins with a breakthrough in the underlying technology. Mobile terminals, smart devices, electric vehicles, robots, etc. to popularize, battery technology breakthrough is essential. Sakti3, a battery start-up company founded in 2007, has been developing and manufacturing high-performance solid-state lithium-ion batteries, and recently they have just received new financing from DYSON1500 million dollars.

Since the birth of lithium batteries, has been the use of liquid electrolyte, flammable, unsafe, so we often see all kinds of lithium battery explosion, not to mention the endurance of the poor. Sakti3 is committed to the development of solid-state batteries in all aspects beyond the traditional lithium battery: it is more secure, even if the battery is split in half or in a high-temperature environment, the battery can continue to work, the battery energy density is also greater than the current best lithium battery, up to more than one times, almost to 1100 watts per liter, Used on smart watches, the range can range from 3.5 hours to 9 hours, on electric cars, mileage from 256 miles to 480 miles, and cheaper, with a cost of $100 per kilowatt hour, well below the current 200 to 300 dollar price.

Earlier, the Canadian Avestor company has also tried to develop solid-state lithium batteries, unfortunately, failed, and finally formally filed for bankruptcy in 2006. Avestor, which uses a polymer separator to replace liquid electrolytes in batteries, has not addressed the safety issue, when it was in cooperation with the US at&t to install solid-state lithium batteries in verse cable boxes, but several battery burns or explosions have occurred in North America.

Sakti3 is reluctant to mention what electrolytes and other technologies have been used. According to the current data, the Sakti3 solid-state batteries are based on thin film deposition technology, which is often used in photovoltaic solar cells. There is no liquid electrolyte inside the battery, but using a "sandwich" device to act as an electrolyte to ensure normal transmission between the ions.

Sakti3, founder of Sastry, was previously enrolled at the University of Michigan Engineering department. 2006, he began to study solid-state lithium battery technology, the establishment of the Sakti3 in 2007. 2009 received $2 million in funding from Khosla Ventures, 7 million dollars in April 2010, and 4.2 million U.S. dollars in September 2010 for GM and Itochu Marvell Ventures.

For General Motors and vacuum cleaner tycoon Dyson, investing in Sakti3 early is equivalent to buying one of the most important insurance. After all, users don't want to buy cars and machines with no electricity.
