New Electrode Technology Drives Leapfrog Improvement in Lithium Battery Performance

In the wave of the new energy industry advancing towards "high energy, fast charging, long service life, and low energy consumption", lithium batteries, as the core energy storage carrier, their performance directly determines the development ceiling of fields such as new energy vehicles, energy storage power stations, and intelligent terminals. For a long time, the traditional wet electrode process has been in use for decades, relying on core links such as toxic solvent mixing and high-temperature drying. It not only pushes up production costs and environmental pressure, but also restricts the release of lithium batteries' core performance due to electrode microstructure defects caused by solvent volatilization. As a national high-tech enterprise incubated by Shenzhen Tsinghua University Research Institute, Tsingyane Electronics has deeply engaged in electrode process innovation. With its independently developed new dry electrode process, it has broken industry bottlenecks, driven leapfrog improvements in lithium batteries' core performance, and laid the foundation for the mass production of solid-state batteries, injecting core momentum into the high-quality development of the new energy industry.

Prominent Industry Pain Points: Traditional Electrode Process Becomes a Constraint on Performance Improvement

As the core component for energy storage and transmission of lithium batteries, the preparation process of electrodes directly determines the comprehensive performance and production cost of batteries. For a long time, the wet electrode process commonly used in the industry requires mixing active materials, conductive agents, and binders with toxic solvents to form a slurry, which is then coated, dried at high temperature, and the solvent is recovered. This process has many insurmountable pain points and has become a core constraint on the performance upgrade of lithium batteries.

From the performance perspective, in the wet process, solvent drying is prone to cause electrode micropore collapse, limiting fast charging efficiency; binders tend to wrap active materials, making it difficult to achieve breakthroughs in energy density; residual solvents also affect battery cycle life and safety performance. From the production perspective, the drying link has high energy consumption and high solvent treatment costs, and the production line is lengthy, which not only pushes up production costs but also is inconsistent with the global trend of green and low-carbon industrial development. With the increasing demand for new energy vehicle range anxiety and long service life of energy storage power stations, the market is in urgent need of a new electrode process with high performance, low cost, and environmental protection. The new dry electrode process developed by Tsingyane Electronics is the core solution to this demand.

Process Innovation: Tsingyane Electronics' New Dry Electrode, Reconstructing Lithium Battery Manufacturing Logic

Different from the "solvent mixing-coating-drying" path of the traditional wet process, Tsingyane Electronics' new dry electrode process takes "solvent-free and precise film formation" as the core logic. It prepares electrodes through the innovative path of "dry mixing-precise forming-in-situ compounding", completely abandoning toxic organic solvents, reconstructing the lithium battery electrode manufacturing process from the bottom, and achieving triple breakthroughs in process, cost, and performance, demonstrating the enterprise's full-chain innovation capability.

The core breakthrough of Tsingyane Electronics' new dry electrode process lies in the collaborative innovation of three key technologies. First, the independently developed powder-in-film technology avoids damage to the material microstructure caused by the wet process through solvent-free dry mixing; second, it innovatively adopts a customized binder to form a nanofiber network structure, which greatly increases the proportion of active materials and expands the energy storage space; third, it builds a high-precision calendering and compounding system, which can prepare electrodes of various specifications to adapt to the needs of different scenarios.

Compared with the traditional wet process, Tsingyane Electronics' new dry electrode process greatly simplifies the production process. One of the most prominent advantages is the significantly shortened production line—eliminating cumbersome links such as slurry preparation, solvent drying, and solvent recovery, and no need for lengthy drying ovens and solvent recovery systems. The length of the production line is greatly reduced compared with the traditional wet production line, which not only significantly reduces the factory floor space, lowers plant construction investment and capital investment, but also shortens the production cycle and improves production efficiency. At the same time, it reduces production energy consumption and raw material loss, completely eliminates harmful gas emissions, which not only reduces production costs but also achieves green and low-carbon production, perfectly complying with the industrial development trend.

Performance Leap: Multi-Dimensional Breakthroughs, Reshaping the Core Competitiveness of Lithium Batteries

The innovation of the new dry electrode process not only optimizes the production process but also promotes leapfrog improvements in lithium batteries' core dimensions such as energy density, fast charging capacity, cycle life, and safety performance by reconstructing the electrode microstructure. It breaks the dilemma of traditional lithium batteries where "high capacity and high power cannot be achieved at the same time", providing better energy storage solutions for multi-field applications.

In terms of energy density, the dry process avoids the wrapping of active materials by binders, can accommodate more active materials, greatly improving the energy density of lithium batteries, effectively solving the range anxiety of new energy vehicles, and supporting the needs of long-range models and large-capacity energy storage power stations.

In terms of fast charging capacity, the dry electrode forms an ion channel with excellent connectivity, which greatly improves the ion migration rate and significantly enhances the fast charging efficiency. It is suitable for scenarios with high fast charging demand such as new energy commercial vehicles, improving the convenience of use.

In terms of cycle life and safety performance, the dry electrode completely avoids solvent residue problems, enhances the stability of the electrode structure, extends the battery service life, and reduces the full-life cycle use cost. At the same time, its dense structure makes the battery perform more reliably under extreme conditions, and its wide temperature adaptability is also greatly improved compared with traditional wet electrode lithium batteries, meeting the use needs of different regions and different scenarios.

Process Empowerment: Helping the Mass Production of Solid-State Batteries

In addition to promoting the performance upgrade of traditional lithium batteries, Tsingyane Electronics' new dry electrode process has become a key support for the mass production of solid-state batteries. As the next-generation lithium battery technology, solid-state batteries replace traditional liquid electrolytes with solid electrolytes, having core advantages of higher energy density, stronger safety, and longer cycle life. They are expected to completely solve the safety hazards and performance bottlenecks of traditional lithium batteries and become the future development direction of the new energy storage field.

The traditional wet electrode process is highly incompatible with solid electrolytes due to its reliance on organic solvents, which easily leads to electrolyte failure and becomes a core obstacle restricting the mass production of solid-state batteries. In contrast, the core solvent-free feature of Tsingyane Electronics' new dry electrode process is naturally compatible with solid-state batteries, which can effectively avoid the damage of solvents to solid electrolytes and ensure the structural stability and performance of solid-state batteries.

At present, Tsingyane Electronics has deeply integrated the dry electrode process with solid-state battery R&D. Relying on its own advantages in materials and processes, it optimizes the interface bonding performance between electrodes and solid electrolytes, solves industry pain points such as high interface impedance and poor ion transmission of solid-state batteries, accelerates the technological iteration and mass production process of solid-state batteries, and provides technical support for the new energy industry to move towards a higher level of development.
