Fisk/Toyota zoom in tips!

It's too early to say whether solid-state batteries will be the next big thing, but it's safe to say that many new energy vehicles around the world are doing their best to make it happen.

Now Fisker, an electric-car brand that used to be bigger than tesla, has made a big move. Fisker filed a patent application for a solid-state battery this week. For a while, solid-state batteries were the buzz.

Right on the tesla

Fisker claims an 800-kilometer range in a minute

Fisker's patent documents show that its new solid-state battery is 2.5 times more energy dense than a lithium-ion battery, with a range of up to 500 miles (805km) on a single 1-minute charge. It plans to commercialize the battery by 2023.

What does this have to do with tesla? Let's talk it over.

Alignment convergence. Fisker was founded in 2005 by former BMW designer HenrikFisker, two years after bitthra. Fisker's first mass production car, the Karma, was officially put into production and went on the market in 2011. Tesla's first car was Roadster, both of which are luxury electric sports cars and priced at about $100,000. The target audience is the wealthy class in the United States, and the main high-end line is the main line.

In the second year after Karma went public, A123Systems, a battery supplier to fisker, went bankrupt due to a battery defect. Without its own battery technology, fisker was forced into bankruptcy protection. In February 2014, it was acquired by China wanxiang group.

New solid-state battery technology charges at a rate comparable to tesla ModelS. According to analysts, the ModelS currently take an hour and 15 minutes to fully charge using the fastest supercharger, with a range of 300 miles (483km). Compared with fisker's Numbers, tesla appears to be in a slightly worse position.

2. Toyota and tesla "love" turns into "kill"

Fall in love. Toyota is understood to have been a shareholder in tesla since 2010, and the two companies worked together for a time, but in June, Toyota sold its entire stake in tesla.

Slaughter. On October 25th didier leroy, Toyota's vice-president, said a new generation of "solid-state" batteries would be introduced by 2025 to extend the range of electric cars. As for the new generation of counter batteries, the two companies hold different views.

In a quarterly earnings call in early September, Mr Musk said of Toyota's solid-state battery plans: "there have been claims of battery breakthroughs all over the world almost every day. We are currently the largest buyer of lithium ion batteries in the world. When someone makes a breakthrough in lithium battery, who will be the first to receive the product? Tesla! Because we are the biggest customer.

Toyota is hot, tesla is cold, and that's probably why the two sides are killing each other. However, it is worth mentioning that since 2010, Toyota has been committed to the research and development of solid-state battery, and its patent reserve is up to more than 30 items. Currently, the prototype product of the experiment has an energy density of about 400Wh/Kg, which can realize the charge and discharge of 1500C, and its performance in tolerance, width and cycle life is also very outstanding.

Development of solid-state batteries in various countries

1. China: ningde era is accelerating the development of sulfide solid state lithium metal battery in terms of sulfide solid state battery.

2. Japan: as early as 2008, Japan NEDO developed the research and development plan, and planned to realize the mass production of solid-state battery in 2030; TakashiTanisho, President of Hitachi sasaki, said samples of the solid-state battery have been sent to potential customers in thespecial and automotive industries. In addition, Hitachi is working with an undisclosed Japanese battery maker to refine some of the details and put solid-state batteries on the market by 2020, possibly not under the Hitachi brand.

3. Germany: at the Frankfurt motor show held on September 12 this year, Volkswagen CEO murren said that the company is already planning the next generation of electric car batteries, with the range of more than 1,000 kilometers of solid-state batteries, which will be mass produced in 2025.

Compared with the traditional lithium battery, all-solid lithium battery has better stability, safer operation, higher energy density, smaller size and lighter weight, which is conducive to the lightweight body and the expansion of application range. In this way, it seems that the power battery will embrace a bright future.

However, the solid electrolyte resistance draft still has some problems to be solved in terms of power density, and even if it is commercialized, its price will be very high.

What's more, according to the mass production time of solid state battery described above, only Hitachi's 2020 is the shortest, but there are too many variables to guarantee that no new battery technology will emerge in the three years.
