Talent and innovation are the foundation for Welion to focus on future technologies
In-situ curing technology
This technology uses self-developed monomer materials and curing process technology to realize the mass production process of solid-state batteries based on in-situ solidification technology, in which the atomic-level bonding between the solid electrolyte and the electrode particles ensures a continuous and conformal solid-solid interface. It can effectively reduce the interface resistance and improve the safety performance of the battery.
Solid electrolyte mixing technology
This technology uses independently developed solid-state electrolyte mixing technology in the anode/cathode to reduce the amount of electrolyte used and improve safety performance, while conducting lithium ions to maintain rate performance.
Ion conductor coated positive electrode
This technology uses fast ion conductor solid electrolyte coating modified positive electrode material technology to improve the interface side reactions and safety performance of high-nickel positive electrode materials.
Ion Conductor Membrane Technology
This technology uses a self-developed solid electrolyte to coat the surface of the diaphragm to replace the aluminum oxide coating to form an ion conductor membrane. This technology can achieve the goal of maintaining the thermal stability of the diaphragm while improving safety performance; at the same time, the solid electrolyte can transmit lithium ions and improve ion conductivity compared to aluminum oxide.
Ultra-thin Lithium Metal Foil
Ultra-thin lithium metal foil and composite negative electrode materials below 20um are prepared by physical methods. This technology can effectively inhibit lithium dendrite growth and improve battery energy density and cycle stability.
Pre-lithiation technology
This technology adopts independently developed ultra-thin lithium foil preparation technology, metal lithium foil surface passivation technology and lithiation rate control technology. By forming an inorganic electrolyte layer at the interface, the metal lithium is embedded in the negative electrode under the multiple effects of electronic conductivity, ion conductivity and metal diffusion to complete lithium replenishment, and an inorganic SEI film is formed on the negative electrode surface in advance.
