According to reports, the company’s lithium‑ion battery products primarily include ternary cylindrical lithium batteries, small‑power PACK systems, and residential energy storage solutions, which are widely used in electric two‑wheelers, portable energy storage, power tools, smart small appliances, and home backup power applications. Meanwhile, an announcement following the second review meeting indicated that Suzhou’s ChiNext IPO has been approved. It is also reported that Hua Yi Shares’ core business involves the R&D, production, and sales of lithium‑battery electrolyte additives, making it one of the earliest domestic companies engaged in this field. The company’s key products—vinylene carbonate (VC) and fluoroethylene carbonate (FEC)—are major electrolyte additives for lithium batteries, extensively applied in new‑energy vehicles, 3C products, and grid‑scale energy storage, among other sectors.

Furthermore, the uncontrolled growth of lithium dendrites can pierce the separator, triggering internal short circuits that may lead to thermal runaway and even explosions. Meanwhile, electrolytes typically consist of conventional carbonate‑ or ether‑based solvents, which have low boiling points, poor thermal stability, and high flammability; under conditions of thermal, mechanical, or electrical abuse, these flammable electrolytes can exacerbate battery combustion and flame propagation. Consequently, the flammability of the electrolyte is a critical factor that significantly impacts lithium‑battery performance.

Curbing global warming and preventing the deterioration of the human living environment have become a global consensus, giving rise to the overarching trend toward new energy. To reduce the share of carbon emissions from automobiles, countries worldwide are vigorously introducing new policies to promote electric vehicles. Lithium batteries occupy a central, pivotal role in this emerging sector, with lithium‑ion batteries relying on four key materials: the cathode, the anode, the separator, and the electrolyte. As we will see next, driven by this major shift toward new‑energy vehicles, the company has achieved rapid growth and has emerged as a global leader in the lithium‑battery separator industry—specifically, in the field of separator materials.

In addition, solid‑state batteries integrate a range of advanced technologies, including ultra‑high specific‑energy cathodes, novel anodes, separator membranes, and cutting‑edge manufacturing processes. Although their electrolytes differ from those used in conventional liquid‑type lithium‑ion batteries, industry insiders have told 36Kr that solid‑state batteries still fall under the category of semi‑solid‑state batteries. Founded in 2022, the company is a technology‑driven R&D firm whose core business focuses on new energy and new materials. Leveraging supramolecular platform technology, it designs and develops high‑performance deep eutectic electrolytes for lithium‑ and sodium‑ion batteries, gradually positioning itself as a catalyst for transformation within the electrolyte industry. The company’s key product lines include lithium‑battery electrolyte additives, lithium‑battery electrolytes, sodium‑battery electrolytes, as well as lithium‑ and sodium‑ion batteries.

The amount of electrolyte injected into a lithium-ion battery directly affects its performance. When the electrolyte filling level is too high, it not only increases manufacturing costs, but also leads to decomposition of the excess electrolyte during charge–discharge, generating gas that degrades contact between the positive and negative electrodes, deteriorates cycling performance, and gives rise to a host of additional issues. Conversely, if the electrolyte injection volume is too low, lithium-ion transport between the electrodes becomes restricted, resulting in increased internal resistance and reduced cycling stability over long-term operation.
