Higher mileage, shorter charging time, more safe to use ... These are the major research institutions and enterprises in the pursuit of the goal of electric vehicles.Nowadays, the electric car manufacturer Fisker (Fisker) is applying for a solid state Battery patent, can make electric car mileage increased to 500 miles (about 805 km), charging time reduced to 1 minute.The company plans to 2023 by the commercial use of the battery.
Founded in 2005 in the State of California, USA, Fisker was founded by BMW's former designer Henrik Fisker and in February 2014 Fisker was renamed as a card by China Universal Group Karma.
According to a report by the Daily Mail on November 14 this week, Fesco submitted a patent for a solid-state battery, a patent that addresses new materials and manufacturing processes, The required energy density, power and cost goals and to promote the promotion and application of electric vehicles is very important.
Solid-state battery is a kind of battery which uses solid electrode and solid electrolyte.Usually often used batteries are mostly liquid batteries, the electrolyte is mostly liquid.As the solid-state battery is relatively high power weight, it is a very good battery for electric vehicles.
However, earlier studies have shown that there are many limitations in the commercial use of solid-state batteries, such as low electrode current densities, limited temperature ranges, limited materials availability, high cost, complicated manufacturing processes, etc. In addition, The failure mode affects the performance of the solid-state battery, which includes high contact resistance in the electrode layer structure and low ion mobility, resulting in a lower discharge capacity of the battery.

Fisker claims that their solid-state batteries are designed to overcome the challenge by using three-dimensional electrodes that have 25 times the surface area of conventional solid-state battery thin-film electrodes and have high electrical and ionic conductivities for fast charging And low temperature operation.
So, the energy density of this solid battery is 2.5 times that of ordinary lithium-ion battery.With the continuous improvement of material and manufacturing level, Fiskos predicts that the cost of such a battery will be one-third of that of the conventional lithium-ion battery by 2020 In addition, the battery explosion risk is relatively low.
Fabio Albano, vice president of battery systems at Fisco, said: "This breakthrough marks the beginning of a new era for solid-state battery materials and manufacturing technology." He also said, 'We are addressing other barriers to solid-state battery commercialization , Such as battery performance under low temperature conditions.
Fisker said the battery will be on display at the International Consumer Electronics Show (CES) in January next year and is expected to be commercialized by 2023. The company is currently working with a potential non-automotive partner Partners to negotiate, it is possible as early as 2023 to commercialize the battery for this application.
In fact, solid-state batteries are not a whole new field of research, and scientists have been working on the technology in the lab for years, but the product has not been used due to issues such as production costs, charge cycle durability, and more.
In addition to Fisker, other companies and research institutes have devoted considerable attention to this area of research and development, for example, Japan's NEDO (Japan's New Energy Industrial Technology Development Organization) formulated its R & D plan as early as in 2008 Solid state lithium battery production, including solid lithium metal, solid state lithium sulfur and solid state lithium air battery, will be realized by 2030. In July this year, Japan Toyota made new progress in the patent of solid state battery and announced that it will launch all solid state Battery of the new electric car.VeneSwiss Volkswagen has also said that it plans to have the next generation of electric car batteries, for more than 1,000 kilometers of solid state batteries, will be in 2025 production.
