Since the Bollore Group and the French Citroen Group jointly launched the world's first passenger car using lithium metal solid polymer batteries in 2016, the world's leading companies have actively deployed the development of solid-state batteries.
Although, all solid-state batteries cannot be fully applied to electric vehicles because of technical problems. However, in May 2017, the Japanese Ministry of Economy announced that it will contribute 1.6 billion yen to Union Toyota, Honda, Nissan, Panasonic, and GS Yuasa. , Dongli, Asahi Kasei, Mitsui Chemicals, Mitsubishi Chemical and other top industrial chain forces, jointly develop solid-state batteries, hope to achieve 800 kilometers of life in 2030.
Especially this year, the progress of car companies in solid-state batteries seems to be more rapid than battery companies. For example, Hyundai announced that it is investing in Ionic Materials in Massachusetts, mainly for solid-state battery research and development; the public has incorporated the Ningde era into the supply chain, etc. ......
Therefore, car companies and some 'oral research and development' battery companies are different, solid-state batteries or will become a new battlefield for new energy vehicles competition at home and abroad.
The following are the developments of solid state batteries for 18 car companies around the world:
Some car companies' solid-state battery investment progress:
Hyundai Motor
In July 2018, Hyundai Motor announced that it is investing in Ionic Materials in Massachusetts, mainly for solid-state battery research and development.
Ionic Materials has made unique advances in solid-state battery technology. The company uses ionic materials to realize the next generation of solid-state batteries. Its breakthrough polymer is the first solid electrolyte that works at room temperature and can be used with a variety of electrodes. Chemical compatibility to significantly improve battery safety, performance and production costs.
Currently, Ionic Materials uses ionic materials to implement the next generation of solid-state batteries. Its breakthrough polymer is the first solid electrolyte that works at room temperature and is compatible with a wide range of electrode chemistries to significantly improve batteries. Safety, performance and production costs.
The solid-state, high-efficiency, high-capacity polymer processing technology simplifies battery manufacturing and enables an overall lower cost package configuration. At the same time, it has twice the lifespan of conventional lithium batteries because, unlike liquid electrolytes, its materials Many of the next generation anodes and cathodes are compatible.
Today, I have received investment from South Korea's Samsung, Dyson and other big technology companies.
Volkswagen
In July this year, Volkswagen spent another $100 million on QuantumScape, a Silicon Valley battery research company that has been working for six years, and formed a joint venture. Last year, Volkswagen announced its aggressive entry into solid-state battery research, and this year it has been a lot of action.
Volkswagen Group CEO Herbert Judith said that Volkswagen plans to produce solid-state batteries on its own, possibly starting mass production in 2024 or 2025.
Volkswagen plans to build a next-generation electric vehicle battery, which is a solid-state battery with a mileage of more than 1,000 kilometers, and will be mass-produced in 2025. Volkswagen plans to replace all models with electric models by 2030, and will invest 50 billion euros into electric vehicle batteries. , 20 billion euros to electric vehicles.
BMW car
BMW announced that it will work with battery technology company Solid Power to develop a new solid-state battery. BMW hopes that the new solid-state battery will take the performance of electric vehicles to a new level and apply it to the BMW xEV series. It is reported that Wanxiang A123 has Invested in Solid Power.
Solid Power previously announced a breakthrough in solid-state battery technology. The company has mixed high-capacity lithium-metal anodes in lithium batteries and created a new solid-state battery that, under the same weight, The power is 2-3 times that of traditional lithium batteries.
Toyota Automotive
On June 15 this year, Japan's New Energy Industry Technology Development Organization (NEDO) announced that it will launch a new generation of high-efficiency battery 'all solid-state battery' with Toyota Motor, Panasonic. It is reported that the latest energy density of Panasonic's research on solid-state batteries is relatively high. 3 to 4 times, small-scale mass production of Gen 4a batteries will be prepared.
Since 2010, Toyota has been committed to the research and development of solid-state batteries. Its patent reserves are more than 30. The current prototype energy density is 400Wh/kg, achieving 1500C charge and discharge, and its performance in wide temperature and cycle life is also outstanding. .
At the same time, Toyota and Ilika Technologies are collaborating on the development of solid-state batteries. It plans to commercialize all-solid-state batteries in the early 1920s and introduce solid-state battery electric vehicles in 2020.
Honda Motor
It is reported that Honda Motor Co. and Nissan are jointly developing an 'all solid state battery' that can extend the driving distance of electric vehicles and significantly shorten the charging time.
Not long ago, a Honda car spokesman said that Honda is currently studying how to use solid-state battery technology in electric vehicles. Contrary to the previous 'working with Nissan' news, the spokesman said that Honda will be self-reliant.
At the same time, Honda and Hitachi Shipbuilding have jointly developed Ah-class batteries, which are expected to be mass-produced in three years.
Audi
Overseas media exposure Audi will launch a new pure electric supercar, and the energy storage group will use solid-state battery technology to balance acceleration performance, cruising range and lightweight demand.
At present, Samsung SDI, which has already supplied some battery packs for Audi e-tron, mainly develops sulfide solid-state batteries, which is the most important component supplier in the future super sports car program. At the beginning of this year, South Korea showed its latest solid state at the North American Auto Show. Battery pack technology.
At the same time, the German KOLIBRI battery has been applied to the Audi A1 pure electric vehicle, which has not yet been commercialized.
Dyson
Dyson, who just entered the electric car market, acquired Sakti 3, a solid-state battery technology company, and announced plans to launch its first electric car by 2020 in September last year.
The Dyson joint venture at the former Royal Air Force Base is worth £2 billion, $2.77 billion, and employs 400 people. Half of the $2 billion is for battery development and the other half for the car itself. Part of the funding comes from the UK government. Innovation fund.
Its latest announcement further clarifies its determination to build a car: First there will be a luxury limited car (halocar), followed by two cheaper models.
Lagonda
At the Geneva Motor Show, Aston Martin announced that he will build a luxury electric car, which will be released in 2023. Recently, its official news, the first pure electric SUV model Lagonda will share technology with Aston Martin Martin DBX And released in 2021.
The official also said that it will be equipped with solid-state batteries and L4-class autopilot, with a cruising range of about 400 kilometers, but the detailed configuration of the model has not been disclosed.
Aston Martin CEO Andy Palmer said that the future belongs to the Lagonda brand, which is a pure electric-powered car, and that Lagonda can sell pure electric vehicles through an independent network in the UK, which will be exhibited at the Aston Martin Brand Center.
It is reported that in 2021, the production plant of Lagonda will be produced in the St Athan factory, just like DBX, but the official did not give a clear response.
