Solid-state battery with energy density twice the current lithium battery is expected to be put into practical use within several years

Using solid rather than electrolyte for electrolyteAll solid battery"From the high battery density, the next generation battery to be installed in electric vehicles is considered to be strong,Toyota and other automobile manufacturers are progressing developmentIt is technology. A startup company called "to commercialize its all solid state batteries in a few years" has appeared.

Secretive Company Claims Battery Breakthrough - Scientific American

Starting companies in the state of Michigan in the United States are planning to commercialize all solid state batteries in a few yearsSaktiSo, until now, I have avoided talking about details on all the solid state batteries under development, either because development is proceeding smoothly, or finally the all solid lithium battery under development "Sakti 3Current situation and future expectations ofScientific AmericanI made it clear.

According to Sakti's Anne Marie Sasey CEO, Sakti 3 is made utilizing the thin film deposition method used in thin displays and solar panels, already twice the highest energy density of current lithium ion batteries We have succeeded in making an all solid state battery with an energy density of 1143 Wh / l. And "Sakti 3 is expected to be commercialized in a few years, the first product to be adopted will be household appliances," says Sagey.


Since all solid state batteries use solid electrolyte instead of electrolyte, the energy density is increased up to 5 times as much as lithium ion battery ratio, and durability is much better than lithium ion battery, so battery life can be improved remarkably It is anticipated that it will become the definitive version of the battery for electric cars, and the automobile manufacturers are hurriedly developing.

Sakti is a venture company created by SASTREY CEO who was appointed professor at the University of Michigan Faculty of Engineering at an unprecedented speed and acquired technology of Sakti 3 itself, 2007 ASME Gas Tas Larsson Award, 2011 ASME Frank Crace Energy Award, etc. We have received numerous awards, including hundreds of millions of dollars (hundreds of millions of yen) from automobile manufacturers such as GM, and expectations from automobile manufacturers such as the fact that former GM executives are also nominated as directors It is a company.


Although Sakura told the selling price of Sakti 3, he said, "Since Sakti 3's manufacturing has made substantial progress in thin film deposition technology, Sakti 3's manufacturing will benefit from this," he said, at a low cost It is suggesting that there was a prospect of manufacturing.

Also, in general, in the US automobile market, fuel economy "300 miles at 100 dollars (about 500 km at 10,000 yen)" is thought to be a line for users to consider purchasing electric vehicles in earnest Where there is, SASTREY expects that technological advances in the thin film deposition process can also clear this fuel efficiency standard.


From the fact that SASTREY CEO boasts outstanding research achievements and the fact that it receives great assistance from automobile manufacturers, the high expectation for Sakti is inseparable. Therefore, we can not but expect the prediction that CEO's "Sakti 3 will be introduced to the market a few more years".
