What are the important differences between polymer batteries and lithium batteries?

The important differences between polymer batteries and lithium batteries are: 1. Polymer batteries do not have battery leakage problems. The battery does not contain liquid electrolyte and uses colloidal solids. There is liquid in the lithium battery. 2. The polymer battery can be made into a thin battery: 3.6V400mAh capacity, and its thickness can be as thin as 0.5mm. Lithium batteries cannot be very thin 3. Flexible polymer batteries: The largest flexible polymer battery is about 900 pieces. Lithium batteries cannot be bent or bent too much. 4. Polymer batteries can be made into a single high voltage: liquid electrolyte batteries can only be connected in series to obtain high voltage, polymer batteries. 5. The polymer battery has no liquid, so it can be made into multiple layers in a single battery to obtain high voltage. 6. The capacity of a polymer battery is twice that of a lithium battery of the same size. Lithium batteries have seven important advantages: 1. Lithium batteries have the advantages of large capacity and high working voltage. The battery has twice the capacity of the same nickel-cadmium battery, which is more suitable for long-term communication. The voltage of a traditional lithium battery is 3.7v, which is three times that of nickel-cadmium batteries and nickel-hydrogen batteries. 2. Powerful charge retention capability allows a wide operating temperature range. After being stored in the open air at (20±5)℃ for 30 days, the room temperature discharge capacity of the battery is greater than 85% of the rated capacity. Lithium battery has good high temperature and low temperature discharge performance, which can be at -20ˉ+60℃, high temperature and discharge performance is higher than other types of cells. 3. Long cycle life. Lithium batteries use carbon anodes. During the charging and discharging process, no dendritic lithium appears on the carbon anode, which prevents the internal dendritic lithium short circuit from damaging the battery. After 1200 continuous charging and discharging, the battery capacity is still not less than 60% of the rated value, which is much higher than other types of batteries, and it is economical for long-term use. 4. High safety, safe and fast charging and discharging. Compared with lithium metal batteries, lithium batteries have short-circuit resistance, resistance overcharge, discharge, shock, vibration, shooting, acupuncture, no fire, no explosion, etc., because it has a special carbon anode electrode instead of metal lithium electrode, which allows Fast charging and discharging, can be charged and discharged in 1c rechargeable battery, greatly improving the safety performance. 5. No environmental pollution. The battery does not contain harmful substances such as cadmium, lead, mercury, and is a clean source of green chemical energy. 6. There is no memory effect. It can be reused at any time, especially in wartime and emergency situations. 7. Small size, light weight and high energy. Generally speaking, the specific energy of lithium batteries is more than twice that of nickel-cadmium batteries. Compared with nickel-hydrogen batteries of the same capacity, the volume can be reduced by 30%, and the weight can be reduced by 50%, which is conducive to small and light portable electronic equipment. Low cost, high performance, high power, high safety and environmental protection are the development direction of lithium batteries. . As mentioned above, as a typical representative of a new type of energy, lithium batteries have obvious advantages, but there are also some shortcomings to be improved.
