Brief description of how the three start-up companies deal with the industrialization of solid-state batteries

Domestic listed enterprises include guoxuan gaoxue, yiwei lithium energy, ganfeng lithium, dang sheng technology, hengdian dongmi, zhengtai electric appliance, etc., which take solid-state battery as the route reserve of next-generation battery technology. The United States, Europe, Japan, South Korea are also in the layout of solid-state batteries, and different mentality, for example, the United States, mainly small companies, start-up companies. With such three enterprises, they have gained the attention of capital, government and vehicle enterprises.

SolidEnergySystems

SolidEnergySystems just closed a $34 million funding round. It did not disclose its c-series investors, but existing ones include temasek, AppliedVentures, general motors, saic and VertexVenturesChina.

SolidEnergySystems energy laboratory at the Massachusetts institute of technology in the United States born of materials science and technology company, was founded in 2012, the founder of Hu Qichao DonaldSadoway battery experts from world famous at the time, the latter had support from the Bill Gates ˙ battery project.

SolidEnergySystems doubles the battery's energy density and hales its weight with an ultra-thin lithium negative electrode and an electrolyte that has both solid and liquid parts. It has been trialled on a small scale for prototype demonstration and professionalspecial market.

(SolidEnergySystems' battery pack forspecial is designed to create "unlimited flight," which includes limits such as operating altitude in cold weather, weight bearing, and endurance that can be improved with the technology.)

SolidEnergySystems also is the subversion of the business model, they think that the real future lies in for the mainstream markets such as consumer electronics and electric vehicles, negative material and electrolyte, to large lithium-ion battery manufacturers to provide these products, with the diaphragm and the positive integration for for different applications (including unmanned aerial vehicle (uav), consumer electronics and electric cars) custom battery.

Because the anode and electrolyte materials are compatible with existing lithium-ion battery manufacturing processes, mass production can be achieved using existing infrastructure, eliminating the need for expensive infrastructure investments. SolidEnergy aims to build an open ecosystem, which it believes means a more seamless end-user experience, faster prototyping, and unlimited growth.

With a technical energy density of 450Wh/kg, about double the current energy density of power cells, SolidEnergySystems plans to expand into electric vehicles by 2020.

SolidPower

SolidPower is a Colorado startup founded in 2012 with funding from the air force, the national science foundation and thespecial defense agency, in addition to the university of Colorado at boulder and the defense advanced research projects agency.

SolidPower scientists used ALD(atomic layer deposition) to solve the defect of high interface resistance and poor contact between solid electrolyte and LiCoO2 in traditional all-solid batteries.

The battery material of SolidPower is 100% inorganic material with no flammable and volatile components. It has excellent shelf life and high temperature stability. In the context of the entire battery system, the cost is significantly reduced by eliminating some of the potential consumption associated with the safety features of the lithium-ion system.

SolidPower currently has a 7,000-square-foot advanced manufacturing facility with new material synthesis, small-batch pilot material and battery production, as well as prototype assembly and characterization capabilities.

SolidPower's partnership with BMW last year brought the company to the forefront, with the company announcing that it will work with SolidPower to advance solid-state batteries (which will be 2-3 times more powerful than conventional lithium-ion batteries) for the next generation of electric vehicles. BMW previously defined the commercialisation of solid-state batteries as "within 10 years" in a vague way.

Sakit3

Sakit3, an 11-year-old spinoff from the university of Michigan, has received venture funding from GMVentures, KhoslaVentures and itochu, and grants from the state of Michigan.

In October 2015, the company was fully acquired by vacuum cleaner innovator dyson for $90 million to solve the problem of insufficient battery life and limited safety of rechargeable lithium ion batteries applied in its products.

Sakit3 battery technology obtained four patents in 2013, which can change the working time of electronic products such as smart watches from 3.5 hours to more than 9 hours, so that the battery pack of smart phones can last for several days or significantly increase the range of electric cars.

Dyson, which last September unveiled plans to launch its first electric car by 2020, has made its determination clearer with its latest announcement: first there will be a luxury halocar, followed by two cheaper models.

Dyson's current joint venture at former raf base is worth 2bn ($2.77bn) and employs 400 people. Half of the $2 billion goes to battery development and the other half goes to the cars themselves. Part of the funding comes from the UK government's innovation fund.
