Classification of polymer lithium batteries:
1. Classification by structure:
Wound type:
Use the same winding process as the production of liquid lithium-ion batteries to wind up the positive electrode, negative electrode and electrolyte membrane, and wrap them with packaging aluminum foil.
Laminated type:
Use the hot pressing process to hot press the positive electrode, negative electrode and electrolyte membrane cut into a certain size together, and wrap them with packaging aluminum foil.
2. Classification by electrolyte:
Gel polymer electrolyte lithium-ion battery, which adds additives to the solid polymer electrolyte to improve the ion conductivity, so that the battery can be used at room temperature;
Solid polymer electrolyte lithium-ion battery, the electrolyte is a mixture of polymer and salt, the ion conductivity at room temperature is low, suitable for high temperature use;
Lithium-ion battery with composite gel polymer positive electrode material, conductive polymer as the positive electrode material, its specific energy is 3 times that of existing lithium-ion batteries, and it is the latest generation of lithium-ion batteries.
Advantages:
High safety:
Made of pure lithium material, equipped with a high-precision Japanese protection board solution, supporting multiple protection functions such as overcharge, over-discharge, short circuit, etc. to avoid battery damage or safety hazards.
Long cycle life:
The cycle life can reach more than 500 times, and the capacity remains 85% of the initial capacity after 500 charge and discharge cycles, which is suitable for long-term use scenarios.
Wide temperature range:
Supports working environment from -20℃ to 60℃, suitable for equipment operation in low or high temperature environments.
Lightweight design:
Compared with traditional batteries, polymer batteries are lighter in weight. With the 553450 size (thickness 5.5mm×width 34.5mm×height 52.2mm), they are suitable for devices that are sensitive to size and weight (such as Bluetooth devices, small electronic devices, etc.).
Application range:
Wearable devices such as Bluetooth headsets and smart watches
Consumer electronics such as portable speakers and mobile power supplies
High-demand scenarios such as drones and model toys.
