Research and Practice of Colloidal Electrolyte

As an important part of the battery, the performance of the electrolyte can directly affect the optimization and improvement of the performance of the battery. Common liquid electrolytes, such as neutral salt solutions and organic solvents, cannot solve the problems of liquid leakage, dendrite growth, element dissolution and collective flow corrosion during battery use, thus limiting and affecting the battery life. The high-quality colloidal electrolyte can form a protective layer to protect the positive and negative electrodes of the battery, thereby improving the electrochemical performance of the battery.

Based on the application requirements of colloidal electrolytes in batteries, Alfa Chemistry can provide preparation routes for colloidal electrolytes for different application fields of batteries. We can not only control the stability of colloidal electrolytes by changing the ratio of gelling agent, dispersion conditions, pH value and other conditions, but also provide suitable current collectors, electrodes and separators according to the research on self-discharge, ion transport and other characteristics of colloidal electrolytes. We provide simple and effective strategies for ensuring long-term stability and durability of batteries.


What Can We Do?

  • Alfa Chemistry selects the appropriate colloidal electrolyte formulation and production process according to the requirements of production scale and application fields.
  • Alfa Chemistry provides improved solutions for colloid preparation methods, which can control the gelation speed by controlling key technical indicators such as the particle size and specific surface area of the raw materials.
  • Alfa Chemistry conducts experiments on the prepared colloidal electrolyte, and determines whether the prepared colloidal electrolyte meets customer needs through various parameters.
