New patent published for Tinci Materials electrolyte, capable of reducing battery impedance and optimizing cell performance.

Recently, the China National Intellectual Property Administration published an invention patent by Guangzhou Tinci High-Tech Materials Co., Ltd. The patent is titled "Electrolyte Additive, Electrolyte, and Battery," which aims to improve the core performance of batteries by optimizing the electrolyte formulation system, providing technical support for performance upgrades in fields such as power batteries and energy storage batteries.

It is reported that the patent application publication number is CN122073261A, the formal application date is November 2024, and it was completed for public disclosure on May 22, 2026. The patent belongs to Tinci Materials' core electrolyte technology R&D system, focusing on innovative optimizations addressing pain points in battery electrolyte modification technology.

According to the patent abstract, the core of this invention is a composite electrolyte additive system, adopting a dual-component combination scheme to construct a novel formulation structure.

Specifically, the additive system comprises two types of components: a first additive and a second additive. The first additive is selected from at least one substance in the class of organic lithium borate compounds, while the second additive is formed by compounding at least one selected from three common functional electrolyte additives: vinylene carbonate, fluoroethylene carbonate, and vinyl ethylene carbonate.

The patent explicitly defines the ratio parameters for the dual components, with the mass ratio of the first additive to the second additive controlled within the range of 0.03 to 6.67. By precisely regulating the component proportions, the optimal performance combination of the electrolyte system is achieved. Compared with traditional single-additive schemes, this composite system can effectively optimize the adaptability of the electrolyte in the electrolytic cell, reducing the overall impedance of the battery at a fundamental level.

Battery impedance is a key core indicator affecting battery charge-discharge efficiency, cycle life, and low-temperature performance. Excessive impedance easily leads to issues such as battery heating, declined rate performance, and accelerated cycle attenuation. This new electrolyte additive scheme developed by Tinci Materials improves the internal electrochemical environment of the battery through formulation innovation, effectively reducing cell impedance and thereby comprehensively optimizing battery performance to meet the upgrade needs of high-end lithium batteries.

As a core supplier of lithium battery electrolytes, Tinci Materials has long been deeply engaged in the R&D of electrolyte and supporting additive technologies, continuously iterating and optimizing formulations and processes. The implementation of this new patent further enriches the company's electrolyte technology reserves, helping to enhance its product adaptability in the field of high-rate, long-cycle, and high-stability lithium batteries, providing solid material technical support for the technological upgrade of the downstream new energy battery industry.
