Currently, solid electrolytes, an important component in all-solid-state batteries, play a decisive role in the stability and overall performance of batteries in the field of new battery materials.
As a professional equipment manufacturer in the field of wet grinding of solid electrolytes in China, Shanghai ELE Company relies on its long-term technology accumulation and continuous improvement to integrate nano-scale wet grinding units based on the characteristics of solid electrolytes to achieve quantitative results for solid electrolytes. Provide solutions for production and significantly reduce production energy consumption.
The Nano-scale wet grinding part includes two sets of grinding systems. One grinding system use the EYW-5 pre-grinding machine as the core. This machine greatly reduces the requirements for mechanical crushing and grinding in the front line, and the feed particle size is not like other bead mill the fineness of the mill must be below the micron level, otherwise problems such as material blocking may occur in the next process, seriously affecting production efficiency. The EYW-5 pre-grinding machine only requires the feed particle size to be less than 2mm, which not only reduces the energy consumption of the front crushing, but also solves the problem of easy blockage. At the same time, it also replaces the mixing emulsification process (after using this machine, the shearing emulsification process can be omitted), realizing multiple processes in one machine, reducing energy consumption while reducing processes, improving production efficiency, and ensuring the feeding of pellets for the next process. path.
For the second grinding system, the smaller the feed particle size required for the fine grinding mill, the better. The second set of grinding system fine grinder uses ELE Nano bead mill. This machine has target grinding fineness requirements of D50<100nm, D90<300nm (based on the actual strip grinding data), and the small size of the configuration can be 0.02 mm grinding beads. The fine grinding process of ELE Nano bead mill solves the crystal specific surface area of the solid electrolyte, increases the ionic conductivity, and improves its electrochemical performance. It also enhances the problems of uneven solid electrolyte crystals and poor surface properties.
To sum up, the application of ELE bead mill in solid electrolyte is mainly due to the reduction of production energy consumption by ELE Nano scale wet grinding unit (compared with some other similar grinding processes on the market, the energy saving is 30%-50%) and at the same time, production efficiency has also been greatly improved, improving economic value and product competitiveness.
ELE Nano scale wet grinding unit has set a technical benchmark for the entire all-solid-state battery industry. It not only greatly improves the production efficiency of solid-state electrolytes, but also leads a new direction of energy consumption reduction in the all-solid-state battery industry and promotes the economic value status of the solid-state battery field. ELE bead mill provides strong technical support for the mass production and marketization of solid-state batteries.
