■ New Technology

ALTP: Electrolyte for All-Solid and Semi-Solid State battery

  • Problems with Current Composite Current Collector

    Flat surface of the collector: poor adhesion to the electrodes
    Sandwich structure makes multi-layer welding impossible

New Generation of Composite Current Collector

Porous structure: excellent adhesion to electrodes
All porous parts are metallized: multi-layer welding possible

Dry Electrode Production Equipment: for laboratory use

  • High Speed Tilted MIXING

    Function: Rotates at a maximum speed of 6000 RPM, creates a three-dimensional space with the individual rotation of the high-speed rotating body and the mixer barrel, and the scraper function that pushes the powder on the wall to the center, and generates shear stress in a direction perpendicular to the rotation direction, resulting in fiberization and elongation

    Advantage: Favorable for fast and uniform mixing, no need for separate cyclone and fiberization equipment.
    The angle of the rotating barrel can be reduced, and usually wet mixing is horizontal, and dry mixing is tilted at an angle, and dry and wet mixing are possible.
  • Ultrasonic MIXING

    Function: Mixes powder with high-pressure air using ultrasonic waves, and is effective in crushing powder due to the characteristics of ultrasonic waves.
    A cyclone can separate powders of a certain weight.

    Advantage: Effectively separates lumped powders with ultrasonic waves, and fiberization occurs through the application of high-pressure force, and no separate fiberization equipment is required.
