Polymer lithium battery is a kind of lithium ion battery with polymer as electrolyte. The basic principle is to transfer lithium ions between the positive and negative electrodes through the electrolyte, thereby generating an electric current. Compared with traditional liquid electrolyte batteries, the electrolyte of polymer lithium batteries has better chemical stability and plasticity, and can achieve higher energy density and safety performance.
Advantages and limitations of polymer lithium batteries
Compared with the traditional liquid electrolyte lithium battery, polymer lithium battery has many advantages, such as higher energy density, better safety performance, longer service life and so on. However, due to the physical characteristics of their electrolytes, the cycle life and charge and discharge rate of polymer lithium batteries are limited, and their production costs are relatively high.
Application field of polymer lithium battery
At present, polymer lithium batteries are mainly used in portable electronic devices, smart watches, smart wearable devices and other small electronic products, as well as electric vehicles, energy storage systems and other fields. With the continuous improvement of polymer lithium battery technology, its application fields are also expanding.
Preparation method of polymer lithium battery
The preparation methods of polymer lithium battery mainly include: solution method, sol-gel method, copolymerization method, stretch-lamination method and so on. Among them, solution method is one of the most widely used preparation methods. The electrodes are assembled into batteries by dissolving polymers and lithium salts in a solution, then coating and drying them on the electrodes.
Electrochemical properties of polymer lithium batteries
The electrochemical performance of polymer lithium battery is an important index to evaluate its performance. Its performance mainly includes voltage, energy density, power density, capacity, cycle life and so on. With the continuous development of polymer lithium battery technology, its electrochemical performance is also improving. Safety performance of polymer lithium battery The safety performance of polymer lithium battery is one of the important indicators to evaluate its application value.
