On December 13, BAIC Blue Valley stated on the interactive platform that the company has completed the development of second-generation solid-state batteries, battery system bench test verification and vehicle (ARCFOXαT) installation verification. At the same time, the research and development of the third-generation solid-state battery is also under planning.

With the increasing popularity of the solid-state battery industry, many leading car companies such as BMW and Ford have entered the market one after another to vigorously promote the commercialization of solid-state batteries. Listed companies such as Ganfeng Lithium and BAIC Blue Valley are accelerating the research and development of solid-state batteries. Industry insiders pointed out that solid-state batteries will become the technological trend leading the development of new energy vehicles, or become a must for giants.(Lithium - Ion Battery Equipment)

achieve phased results

Recently, many listed companies announced their phased achievements in the development of solid-state batteries, and accelerated the follow-up research and development work.

BAIC Blue Valley said on the interactive platform that the company has now completed the development of the second-generation solid-state battery cell, the battery system bench test verification, and the vehicle (ARCFOXαT) installation verification. At the same time, BAIC Blue Valley said that the planned third-generation solid-state battery technology plans to match the new models of the Jihu brand, and develop a solid-state battery with high safety (no fire) and high energy density (cell energy density of 360Wh/kg). Currently in the process of model project approval.

In addition to BAIC Blue Valley, Ganfeng Lithium has also achieved phased results in the development of solid-state batteries. A few days ago, a reporter from my country Securities News learned from Ganfeng Lithium that the first batch of Dongfeng E70s equipped with Ganfeng hybrid solid-liquid lithium-ion batteries will undergo a test run ceremony in Xinyu, Jiangxi Province. The model is expected to be delivered before the Spring Festival. At present, Ganfeng Lithium Battery, a subsidiary company, has built a 0.3GWh mixed solid-liquid lithium-ion battery production line and put it into use. It has the capacity for mass production and is continuously increasing its output.

The relevant person in charge of Ganfeng Lithium Industry said that the company has realized the loading of mixed solid-liquid lithium-ion batteries based on flexible solid-state separators. Boxes and other abuse tests that are higher than the most stringent national standards.

The above-mentioned person in charge also said that the hybrid solid-liquid lithium-ion battery has high grouping efficiency. The module adopts an aluminum alloy frame and high-precision seam laser welding technology, which reduces redundant structural design and improves the overall grouping rate to more than 86%. , ahead of the average level of the soft package module industry.

At the same time, Ganfeng Lithium is also stepping up the research and development of second-generation solid-state lithium-ion batteries. Different from the first-generation solid-state battery, the second-generation battery is based on high-nickel ternary cathode materials and metal-containing lithium anode materials. At present, the energy density of the product exceeds 350Wh/kg, and the cycle life is close to 400 times. The metal lithium and lithium products used in the battery are the key anode materials for solid-state lithium-ion batteries. Therefore, Ganfeng Lithium Industry added an annual output of 7,000 tons of metal lithium in April this year. The project plans to invest 2.2 billion yuan.

The entry of giants to promote the commercialization process

Due to its obvious performance advantages in safety, reliability, energy density, cycle life and other aspects, solid-state batteries are considered by the industry as an ideal next-generation battery technology system. In recent years, BMW, Ford, Weilai and other car companies are accelerating the deployment of solid-state battery business and accelerating the commercial application of solid-state batteries.

In January this year, NIO announced a 150kWh solid-state battery with an energy density of up to 360Wh/kg, a 50% increase in energy density. The high-capacity battery will be delivered in the fourth quarter of 2022. Based on the battery with this energy density, the NEDC cruising range of NIO ET7 can exceed 1,000 kilometers.
