Introduction | mybattery

Yongtai Technology’s subsidiary Shaowu Yongtai High-tech Materials Co., Ltd. plans to invest 550 million yuan to upgrade and expand its existing capacity to produce 50,000 tons of lithium hexafluorophosphate annually, and to invest 270 million yuan to build a new 5,000-ton lithium supplement agent project. The total investment is expected to be 820 million yuan.

On the evening of March 13, Yongtai Technology (002326) announced that its subsidiary Shaowu Yongtai High-tech Materials Co., Ltd. (hereinafter referred to as “Yongtai High-tech”) plans to invest 550 million yuan to upgrade and expand its existing capacity to produce 50,000 tons of lithium hexafluorophosphate annually, and to invest 270 million yuan to build a new 5,000-ton lithium supplement agent project. The total investment is estimated at 820 million yuan.

Specifically, the capacity expansion project for 50,000 tons of lithium hexafluorophosphate will upgrade the existing production line of about 18,000 tons per year, aiming to establish an annual production capacity of 50,000 tons of lithium hexafluorophosphate (solid salt). The construction period is expected from March 2026 to December 2027, funded by self-raised capital.

The new 5,000-ton lithium supplement agent project aims to establish an annual production capacity of 5,000 tons. The construction period is expected from June 2026 to December 2028.

Battery Network notes that prior to this (March 2), Yongtai Technology officially announced the cancellation of its subsidiary Yongtai High-tech’s 200,000-ton electrolyte and related materials and by-product recycling project.

Similarly, in early March, Yongtai High-tech announced the cancellation of the electrolyte project, and in mid-March, it announced an increase in lithium hexafluorophosphate and new lithium supplement agents. Yongtai Technology stated that the electrolyte project was canceled because, since its preparation, significant changes in market environment and industry competition had occurred. As of the date of this announcement, the project was still in the preliminary stage, with only land use rights purchased and no other substantial investments or actual benefits realized. To optimize resource allocation and improve production layout, the company canceled the project while ensuring that existing and planned capacities are sufficient to meet future market demand.

Regarding the new project expansion, Yongtai Technology said that the company has launched the capacity expansion of lithium hexafluorophosphate to break through current capacity bottlenecks through process upgrades, matching the rapid growth of downstream new energy vehicle and energy storage markets, while optimizing cost structure and increasing self-supply of core raw materials to strengthen the industrial chain synergy.

At the same time, the new lithium supplement agent, as an innovative “lithium carrier molecule,” can precisely replenish active lithium lost during battery cycling, significantly extending battery life and restoring capacity. This material can be used for repairing old batteries and manufacturing new ones, including liquid, semi-solid, and solid-state batteries. Currently, its main application is during battery manufacturing, by pre-adding it to cathodes or electrolytes to compensate for irreversible lithium loss caused by SEI film formation during the first charge and discharge. This process can effectively improve the initial Coulombic efficiency and energy density of batteries, optimize cycle stability, and significantly extend lifespan.

Relying on the company’s established product matrix in lithium hexafluorophosphate, lithium bis(fluorosulfonyl)imide (LiFSI), ethylene carbonate (VC), and electrolytes, this new lithium supplement agent project will further improve Yongtai Technology’s complete lithium battery material industry chain layout. This not only helps the company enter high-growth new material sectors but also provides strong support for building differentiated competitive advantages in next-generation lithium battery materials.

In previous research activities, Yongtai Technology revealed that it has developed a series of organic lithium supplement products, such as trifluoromethylsulfonic lithium. The construction of this project may indicate that the company is officially moving frontier lithium supplement technology from laboratory R&D to large-scale production.

In addition to the above Yongtai High-tech project, on March 2, Yongtai Technology also announced plans to sign an “Investment Agreement for a 200,000-ton Lithium Battery Electrolyte Project” with the Coastal Industrial Park Management Committee of Binhai Economic Development Zone in Jiangsu. The project aims to invest in the construction of an electrolytes plant with an annual capacity of 200,000 tons (tentative name, subject to final government approval), with a total estimated investment of 500 million yuan, subject to actual investment.
