Solid state battery materials

With the increasing demand for high-performance batteries in the market, solid-state batteries have great potential for development in various application scenarios such as low altitude economy, embodied intelligence, and new energy vehicles due to their high energy density, high safety, and long cycle life. In the future, with the continuous upgrading of related technologies and the gradual maturity of the industrial chain, solid-state batteries will further lead the innovation and development of battery technology.

The performance breakthrough of solid-state batteries highly depends on the innovative optimization of material systems. The company focuses on the iterative technology and cutting-edge products of new energy battery materials, and has comprehensively laid out key materials for solid-state batteries such as single-walled carbon nanotubes, high nickel ternary precursors, lithium rich manganese based precursors, silicon carbon negative electrodes, sulfide/oxide electrolytes, and metal lithium negative electrodes. It is steadily moving towards the goal of becoming a "provider of all material solutions for solid-state batteries".

Core Product

Silicon-carbon anode

The core of the company's new gas-phase silicon carbon negative electrode is the independently developed porous carbon matrix. The unique porous carbon matrix, such as non activated porous carbon matrix and spherical porous carbon matrix with very concentrated particle size, creates corresponding silicon carbon negative electrode products with high first effect, low expansion, and long service life.

Single walled carbon nanotube powder/slurry

The performance of the company's single-walled tube powder products, such as purity, ratio table, G/D value, etc., is comparable to that of imported single-walled tubes. The company's single wall pipe slurry uses self-developed dispersants, which also outperform imported products in viscosity, solid content, and other indicators.

Solid-state electrolyte

The company's sulfide and oxide electrolytes have achieved high ionic conductivity and good chemical compatibility, especially the solid-state batteries using this electrolyte have maintained high capacity and efficiency after multiple cycles, demonstrating excellent rate performance and long cycle stability. We are actively conducting sample testing with multiple leading enterprises.
