The principle of a lithium battery refers to its charge–discharge mechanism. During charging, lithium ions are generated at the battery’s positive electrode and migrate through the electrolyte to the negative electrode. In contrast, the operating principle of a lithium–carbon dioxide battery is that, upon charging, lithium ions move from the positive electrode, via the electrolyte, to the negative electrode. The carbon used as the negative electrode has a layered structure with numerous micropores; the lithium ions reaching the negative electrode intercalate into these micropores. Consequently, the greater the number of intercalated lithium ions, the higher the charge capacity.

The company’s main battery‑chemical products are categorized as follows: lithium‑ion battery chemicals (including lithium‑ion battery electrolytes, additives, novel lithium salts, and carbonate solvents), supercapacitor chemicals, and primary lithium‑battery chemicals. Cutting‑edge product areas include sodium‑ion battery chemicals and solid‑state battery materials. In addition to the 46‑series large cylindrical cells and the LF560K, the company has conducted extensive, multi‑pronged research and strategic deployment in emerging technologies. During the reporting period, it unveiled innovations such as lithium‑metal secondary batteries, semi‑solid‑state batteries, sodium‑ion batteries, and hydrogen‑energy technologies. This article primarily focuses on its energy‑storage segment.

(300037): The company’s core business involves the research, development, production, and sales of advanced electronic chemicals. Its main product lines comprise two major categories—capacitor chemicals and lithium‑battery chemicals—covering four specific product types: aluminum electrolytic capacitor chemicals, solid‑state polymer capacitor chemicals, supercapacitor electrolytes, and lithium‑ion battery electrolytes. According to available information, Chaoneng New Energy was established as a developer and manufacturer of key materials and batteries for sodium‑ion technology. The company independently develops critical materials for sodium‑ion batteries, focusing on low cost, long cycle life, high energy density, and superior performance.

Its operating principle relies on the insertion and extraction of sodium ions within the materials of the positive and negative electrodes, enabling energy storage and release. During charging, sodium ions migrate through the separator from the positive electrode to the negative electrode; some sodium ions desorb from the positive electrode and enter the electrolyte, while others in the electrolyte intercalate into the lattice spaces of graphite or hard carbon materials. During discharging, the process reverses: sodium ions desorb from the negative electrode and intercalate into the positive electrode, with sodium ions moving from the negative to the positive electrode. In his presentation, Technical Director Lü Liang stated that as lithium‑ion batteries find increasingly broad applications—particularly with the widespread adoption of new‑energy vehicles and large‑scale energy‑storage projects—

According to the announcement of the results from the second review meeting, Suzhou’s IPO application on the ChiNext board has been approved.

As automotive electrification and automation accelerate, product innovation and technological iteration in the automotive sector are gaining momentum. Consequently, electric‑vehicle manufacturers and battery suppliers face a host of pressing challenges, including time‑to‑market, cost management, and battery performance. A breakdown of an EV’s cost structure reveals that the battery system accounts for the largest share of expenses; moreover, both cathode materials and electrolyte production rely heavily on lithium. The 4680 battery is a next‑generation cell that features larger dimensions and higher capacity, incorporating a novel electrolyte and separator.

Lithium‑ion battery electrolyte serves as the medium for ion transport and charge transfer between the positive and negative electrodes, determining key performance metrics such as energy density and power density. Depending on the downstream application, electrolytes are classified into consumer‑electronics electrolytes, power‑battery electrolytes, and energy‑storage electrolytes. Among these, conventional 3C electrolytes meet the demands of high capacity and high rate capability, while power‑and‑energy‑storage electrolytes are designed to deliver long cycle life and superior performance. A condensed phase refers to a system composed of a large number of particles that exhibit strong interactions among them. Ning

The main components of a lithium battery are the positive electrode, the negative electrode, the electrolyte, and the separator. Among these, the materials of the positive and negative electrodes determine the battery’s energy density, while the electrolyte and separator enable the free passage of lithium ions, thereby completing the electrical circuit—both playing a pivotal role in the battery’s performance. Under these conditions, both battery capacity and charging speed—the two core factors behind range anxiety in electric vehicles—can ultimately be traced back to challenges in battery materials. There is no doubt that battery materials science has become a critical area driving advances in electric‑vehicle technology, whether viewed from the perspective of enhancing energy density or improving charging efficiency.
