Recently, JAC Yttrium, a subsidiary of JAC, officially signed a strategic cooperation agreement on solid-state batteries with Weilan New Energy, and the two sides will cooperate in the development of 4695 large cylindrical semi-solid-state cells.
As a new energy vehicle brand with 18 years of technology research and development and industrial accumulation, JAC Yttrium has been focusing on the research and application of various power batteries for many years.
For the sake of safety priority, JAC Yttrium has developed industry-leading zero thermal diffusion cellular battery technology in order to adhere to the cylindrical cell route, and is the first automobile brand in China to research and apply 18650, 21700 and 4695 cylindrical cells. In terms of cutting-edge technology in the field of battery applications, JAC Yttrium is also at the forefront of the industry. On January 5 this year, JAC Yttrium officially delivered the world's first mass-produced sodium-ion battery model to users, marking the most important step in the industrialization of sodium-ion batteries and a milestone.

For the "solid-state battery" that has been hotly discussed in the industry recently, JAC Yttrium has started the production and research of related technologies as early as 2021. Different from other automobile brands, JAC Yttrium and Weilan New Energy will jointly develop semi-solid cells based on 4695 large cylindrical shape, which is the first automobile brand in the industry to explicitly apply large cylindrical semi-solid batteries.
Weilan New Energy is a battery enterprise focusing on the R&D and production of semi-solid-state lithium-ion batteries in China, with a number of core patents for solid-state batteries, focusing on low-cost, long-life, high-safety, and high-energy-density semi-solid-state lithium-ion battery products.
It is reported that the two sides will be based on JAC Yttrium for the world's second-generation pure electric platform - DI platform, to jointly develop 4695 large cylindrical semi-solid battery cell application model, the model will use in-situ solid-state technology, cell capacity of 34Ah, energy density up to 300Wh/kg, to achieve the vehicle 600km-1000km endurance level, and plans to achieve mass production in 2025.

The strategic cooperation between the two parties is of great significance to promote the mass production and installation of 46 large cylindrical semi-solid battery cells. This is also another important move of JAC in the field of battery application after the mass delivery of the world's first sodium-ion battery production vehicle, marking the most critical step in the research and production of solid-state batteries by JAC, and once again leading the second half of the new energy vehicle era.
