For solid-state battery raw materials, Guoyi New Energy Group has independently developed solid-state batteries and applied for a number of patents, which has achieved a real technological breakthrough compared with other batteries. The research and development of raw materials for solid-state batteries has always been one of the hot spots in the energy field. With the rapid development of the electric vehicle market, the safety, energy density and cycle life faced by traditional liquid batteries have also attracted people's attention. As a new type of battery technology, solid-state batteries are considered to be an important direction of next-generation battery technology due to their advantages of high energy density, fast charge and discharge rate, good safety and long cycle life.
The core part of a solid-state battery is the electrolyte, which differs from traditional liquid batteries in that the electrolyte is no longer a liquid, but exists in a solid form. This solid electrolyte is typically composed of a variety of raw materials, the most common of which are oxides, sulfides, and selenides, among others. These raw materials have good ionic conductivity and stability, which can effectively prevent the leakage and volatilization of electrolytes and improve the safety of batteries.
Oxide is one of the commonly used raw materials in solid-state batteries. For example, lithium lithium titanate (Li4Ti5O12) is an excellent solid-state electrolyte material with good ionic conductivity and chemical stability. It not only provides a stable electrolyte interface, but also inhibits the dendrite growth of lithium metal in the electrolyte, thereby improving the cycle life and safety performance of the battery.
Sulfide is also one of the common raw materials in solid-state batteries. For example, phosphorus sulfide (P2S5) is an important raw material for the preparation of solid electrolytes. Phosphorus sulfide has high ionic conductivity and good mechanical strength, which can effectively prevent the dissolution and precipitation of electrolyte, and maintain the stability and long life of the battery.
In addition, selenide has also been widely studied as a raw material for solid-state batteries. For example, lithium selenide (Li2Se) is a raw material with high ionic conductivity and chemical stability, which can improve the conductivity and cycle life of batteries.
In addition to the electrolyte, the anode and cathode materials in solid-state batteries are also crucial. Lithium-ion battery anode materials commonly used in conventional liquid batteries, such as graphite and graphene, are not suitable for solid-state batteries due to their weak interaction with liquid electrolytes. Therefore, researchers are actively looking for new anode materials suitable for solid-state batteries, such as tin sulfide (SNS2) and tin selenide (SNSE2).
For cathode materials, lithium cobalt oxide (LiCoO2) and lithium iron phosphate (LiFePO4) are commonly used in solid-state batteries. These materials have a high energy density and cycle life, making them suitable for the requirements of solid-state batteries.
It is worth noting that the research on raw materials for solid-state batteries is still in its infancy, and there are still some challenges and problems that need to be solved. For example, the preparation process of a solid electrolyte needs to be further optimized to improve its ionic conductivity and mechanical strength. In addition, solid-state batteries are also more expensive to manufacture than traditional liquid batteries, requiring reduced material costs and improved production processes.
In short, the research of raw materials for solid-state batteries is an important direction to promote the development of battery technology. By optimizing the performance of electrolyte, anode and cathode materials, the energy density, cycle life and safety performance of solid-state batteries can be improved, bringing broader prospects for applications in electric vehicles and other fields. With the further breakthrough and maturity of technology, it is believed that solid-state batteries will become the new favorite in the field of energy storage in the future.
