As a type of electrochemical energy storage device, batteries are widely used in various fields such as smartphones, electric vehicles, fixed chargers, in car chargers, military and medical equipment, digital cameras, etc. With the progress and development of technology, people's requirements for battery capacity, weight, volume, and other aspects are also increasing. The three elements of a typical battery are the positive electrode, negative electrode, and electrolyte. The so-called polymer lithium-ion battery refers to a battery system that uses polymer materials at least one or more of the three elements. Polymer lithium-ion batteries have significant advantages over traditional batteries in terms of service life, battery capacity, and ion conductivity. In this article, the editor will lead you to a specific understanding of the advantages and disadvantages of polymer lithium batteries.
Advantages of polymer lithium batteries: 1. The working voltage of individual batteries is high. The working voltage of individual batteries can reach up to 3.6v~3.8v, which is much higher than the 1.2V voltage of nickel hydrogen and nickel cadmium batteries; 2. High energy density, low internal resistance, and a single battery capacity of up to 20WH. The battery voltage can be increased through series and parallel connection, which can meet the design requirements of higher voltage and capacity; 3. Long cycle life, up to 300 times and over 500 times; Currently, it can reach over 1000 times. 4. Good safety performance, pollution-free polymer lithium-ion batteries have an aluminum plastic soft packaging structure, which is different from liquid batteries with metal shells. Once safety hazards occur, liquid batteries are prone to explosion, while polymer batteries can only inflate drums. 5. Low self discharge and minimal capacity loss after prolonged storage; 6. Long cycle life can reach over 500 cycles; 5. No memory effect, no need to empty the remaining battery before charging, convenient to use; 7. Thin in thickness, light in weight, and space saving, it has become the best choice for mobile electronic product power supply, even applied in credit card chips. Polymer batteries are 40% lighter than steel shell lithium-ion batteries of the same capacity and 20% lighter than aluminum shell batteries; 8. Multiple shapes can be customized, with molds limited to a small extent, and can be made into curved or irregular shapes and sizes; 9. Low internal resistance: The internal resistance of polymer cells is smaller than that of general liquid cells; 10. Excellent discharge characteristics. Polymer batteries use colloidal electrolytes, which have stable discharge characteristics and a higher discharge platform compared to liquid electrolytes; 11. The design of the protective board is simple. Due to the use of polymer materials, the battery cell does not ignite or explode, and the battery cell itself has sufficient safety
Disadvantages of polymer lithium batteries: 1. High battery cost and difficulty in purifying the electrolyte system; 2. It is necessary to protect the circuit control. Overcharging or discharging can damage the reversibility of chemical substances inside the battery, thereby seriously affecting its lifespan.
