Advantages:
Miniaturization and Lightweighting: Lightweight and compact batteries are ideal for space- and weight-sensitive applications, such as smart wearable devices or portable electronics.
Design Flexibility: Can be manufactured in any shape and thickness, and is even flexible (maximum bending angle approximately 900 degrees), meeting the styling requirements of complex devices.
Enhanced Safety: The gel electrolyte reduces the risk of leakage and explosion; internal problems are typically indicated by bulging packaging, enhancing reliability.
Capacity and Voltage Advantages: Higher capacity for the same size compared to traditional lithium-ion batteries, and high voltage per cell contributes to improved system efficiency.
Environmental Adaptability: Wide operating temperature range (e.g., -40°C to 70°C), suitable for extreme environmental conditions.
