π Usher in a new era of battery technology: semi-solid batteries! π
π What is a semi-solid state battery?
Semi-solid batteries combine the advantages of liquid and solid electrolytes. It not only has a high energy density, but also significantly improves safety and cycle life.
π Why choose semi-solid batteries?
1. Higher safety: significantly reduce the risk of thermal runaway to ensure the safety of equipment and users.
2. Longer life: Excellent cycle stability, extending the battery life.
3. Higher energy density: Longer battery life for electric vehicles and portable devices.
Solid state battery has excellent safety performance:
(1) Bending test: under full charge, bidirectional bending of 90Β°, no significant change in voltage/temperature;
(2) Knife test: under full charge, the battery is cut without smoke or fire, and the temperature is not significantly changed; (3) Multi-point acupuncture test: under full charge, 3 steel needles with a diameter of 8γ Pierce the battery, the battery does not smoke or fire, and the voltage/temperature does not change significantly;
(4) Extrusion test: deformation degree β₯45Β° under full charge, battery does not smoke or fire, and voltage/temperature does not change significantly;
(5) High-altitude drop test: under full charge, the battery falls from a height of 30 meters, no smoke or fire, and there is no significant change in voltage/temperature.
π Future outlook
With the continuous progress of technology, the cost of semi-solid state batteries will gradually decrease, and it is expected to usher in large-scale commercial applications in the next few years.
