Tsingyane Invited to Attend the 5th 2025 xEV Battery Forum

On November 3rd, the 5th 2025 xEV Battery Technology Forum & the 3rd 2025 Solid-State Battery Technology Industry Conference was held in Jiading, Shanghai. With the theme of "Safety of Liquid Lithium-Ion Batteries for New Energy Vehicles and Advancement of Solid-State Battery Mass Production", this conference conducted in-depth discussions on the market strategies, technological trends of liquid lithium-ion batteries for new energy vehicles, as well as the industrial development and application of solid-state batteries, jointly exploring the future market form and opportunities.

Li Xin, Deputy General Manager of Shenzhen Tsingyane Electronic Technology Co., Ltd., stated in his keynote speech titled "Dry Electrode Technology Accelerates the Industrialization of All-Solid-State Batteries" that all-solid-state batteries, with their disruptive technological advantages of high energy density, high safety, and long cycle life, have become a core cutting-edge development direction in key application fields such as new energy vehicle energy storage. They are also a crucial path to break through the current performance bottlenecks of lithium-ion battery technology.

As a core force in the dry electrode field, Tsingyane focuses on solving two major core challenges of all-solid-state batteries: "incompatibility of traditional wet processes" and "poor solid-solid interface contact", and has achieved disruptive breakthroughs in its self-developed dry electrode technology. In response to the special material requirements of solid-state batteries, Tsingyane has developed a "dry-process-specific material system" to support electrode performance and stability, with key achievements as follows:

1. Dry-process-specific PTFE binder (TYB-005): Through the optimization of micro-morphology and process (fibrosis process), it achieves complete fibrosis, and possesses thermal stability and mechanical strength required for high stretch ratio. It is suitable for paste extrusion with low reduction ratio, solving the problem of ion conduction blockage caused by traditional binders.

2. Dry-process-specific carbon-coated foil (aluminum foil/copper foil): It reduces interface contact impedance and battery internal resistance, improves the bonding adhesion between active materials and current collectors, enhances peel strength, reduces internal polarization of batteries, improves the discharge rate of batteries, increases the specific capacity of high-rate batteries, and inhibits electrolyte corrosion on current collectors and the formation of lithium dendrites. It is compatible with the composite needs of dry electrodes and solid electrolytes.

In addition, Tsingyane has independently developed dedicated equipment for dry electrodes, realizing in-depth integration of process and equipment to support large-scale production. The multi-roll double-sided film-forming composite integrated equipment achieves mass production capacity for dry anodes with a width of 1200mm and a speed of 80m/min. Core equipment for the pre-process, such as the integrated mixing and homogenizing machine, features advantages including efficient cooling, low residue, and high uniformity, providing support for large-scale production.

Standing at the tide of comprehensive electrification and global energy structure transformation, Tsingyane takes powder film-forming technology as its core, continues to deepen research on cutting-edge dry electrode processes, and further collaborates with industrial chain partners including material suppliers, battery manufacturers, and automotive companies. It is committed to promoting the high-quality collaboration of the new energy industrial chain from "technological R&D to engineering mass production", and joins hands with all sectors to build a sustainable solid-state battery industrial ecosystem, helping China seize technological technological high ground and industrialization opportunities in the global all-solid-state battery competition.
