Lithium battery grabs beach 2025

Competing for the earliest landing time, QS has set the mass production time in 2024, and said that it will establish a joint venture with Volkswagen Group to produce solid-state batteries and supply batteries for its electric vehicles.

In January this year, QS Company disclosed on social media that its solid-state battery products had an energy density of over 1000Wh/L, completed nearly 1100 cycles of testing, and still maintained 80% The above capacity.

'We are the first to solve solid-state problems. No other solid-state system can approach this

Huineng Technology is facing the challenge of this confidence. This is an innovative company from Taiwan, China, which claims that its technology is seven years ahead of QS.

Different from QS’s conservative approach to electrolyte technology, Huineng Technology revealed that the technology route it chose was an oxide system, and the positive and negative electrodes were the same as QS, using ternary elements. Material and metal lithium.

Huineng Technology stated that its prototype battery has been manufactured, with a mass energy density of 383Wh/kg and a volume energy density of 1025Wh/L. The cycle test can be done 500 times.

Regarding the mass production plan, Huineng Technology is also similar to QS. It is scheduled to conduct trial production in 2023 and mass production in 2024. There are 4 companies that openly cooperate with Huineng Technology, FAW, Tianji, Weilai and Ai Chi.

From the information released by the two companies, product performance and mass production time are very close. Is Huineng Technology a gimmick or strength to challenge QS? It remains to be seen. At present, it is obvious that the leading part of Huineng Technology is the construction process of its production line.

Huineng Technology has determined to build a factory in Qingshan Lake Science and Technology City in Hangzhou, Zhejiang Province. The project plans to invest 38 billion yuan in total, with a cumulative production capacity of 7GWh. It is expected to be by June this year. Completed the construction of 1GWh production line.

According to Huineng Technology, its own technical preparation and verification have not been a big problem, and the follow-up mainly solves the problems of production line construction and supply chain system maturity.

The mass production of solid-state batteries needs to go through the laboratory-small test-pilot test-mass production and other links. Huineng Technology believes that most other companies are in the stage of small-scale and pilot-scale trials, and they have already reached the stage of mass production.

At the same time, this arrogant company judged that Toyota's layout in the solid-state battery field is much faster than that of other companies such as QS, but there is a four-year gap with it. .

Toyota is recognized as one of the most powerful players in the field of solid-state batteries in the industry. Looking back at its layout time, Toyota first proposed relevant developments in 2008, when it cooperated with the solid-state battery start-up Ilika.

In 2014, Toyota announced that it is developing solid-state batteries and has the most technical patents. In 2017, Toyota announced that it has joined hands with Panasonic, indicating that the two parties will carry out long-term and in-depth cooperation in solid-state battery research and development.

Focusing on the cooperation in the field of power batteries, Toyota and Panasonic also established a joint venture, PrimePlanet Energy u0026 Solutions Inc., with a 51:49 shareholding ratio. The joint venture started operations in April 2020 and now has approximately 5,100 employees.

Toyota adopted the sulfide technology route and originally planned to showcase the research and development results of solid-state batteries at the 2020 Tokyo Olympics. Affected by the epidemic, the plan had to be postponed to 2021.

Although it did not disclose specific data, Toyota said that it has successfully manufactured samples of solid-state batteries as planned and installed them in concept cars, hoping to become the world’s first mass-produced solid-state battery. Manufacturers of battery cars plan to launch prototype cars in 2021 and start mass production around 2025.
