With the continuous innovation of battery technology, solid electrolyte has gradually become a hot spot in scientific research and industry because of its safety, long cycle life and high energy density characteristics.
In this field, oxide solid electrolytes show great research and application potential due to their moderate electrical conductivity, stable chemical properties, relatively low cost and environmentally friendly preparation process.
This paper will discuss in depth the oxide solid electrolyte production process solutions developed and successfully applied by Boyee Company.
The core competitiveness of oxide solid electrolytes is their ability to increase the energy density of batteries by thinning the electrolyte layer.
Compared with traditional liquid electrolytes, solid electrolytes avoid the use of flammable and explosive liquids, thus greatly improving the safety of the battery system.
At the same time, the oxide solid electrolyte also has high ionic conductivity and stable chemical properties.
These characteristics ensure that the battery can maintain stable cycle performance over a long period of time, thereby enhancing the battery life.
As the first to enter the new nanomaterials industry in China, Boyee Company is a pioneer in the development of oxide solid electrolyte production process.
The process solutions developed by the company cover two preparation processes, dry mixing and wet mixing.
In the dry mixing process, the raw material is formed into a uniform solid electrolyte powder through the steps of unpacking and feeding, accurate weighing, dry mixing, kiln sintering, air crushing, grinding, demagnetization and filtration, and automatic canning.
On the basis of dry mixing, an appropriate amount of solvent or dispersant is added to the wet mixing process to promote the mixing and dispersion of raw materials.
And after spray drying treatment to remove solvent or water, finally get a dry solid electrolyte powder.
This process solution from Boyee has significant advantages. The solution precisely controls the raw material ratio and process parameters, making the product performance more reliable and consistent.
The preparation process is not harsh on the environment, reduces the pollution to the environment, and is in line with the development trend of green production.
At present, this proven process solution has been successfully applied to the production of oxide solid electrolytes in several companies, providing strong support for the development of solid-state battery technology.
