How to distinguish between polymer battery and lithium battery

First of all, polymer batteries are also a type of lithium batteries. As long as you open the outer packaging label of the battery, you will be able to distinguish the battery cells easily. The silver plastic package is a polymer battery, and the metal case is a common mobile phone lithium battery. The negative electrode of lithium battery is a carbon material, such as graphite. The positive electrode is a transition metal oxide containing lithium, such as LiMn2O4. The electrolyte is an organic solution containing lithium salt. Generally, lithium batteries do not contain metallic lithium. When charging, lithium ions are extracted from the positive electrode lattice under the drive of an electric field, pass through the electrolyte, and are inserted into the negative electrode lattice. When discharging, the process is just the opposite. Lithium ions return to the positive electrode, and the electrons pass through the electrical appliances and reach the positive electrode from the external circuit to recombine with lithium ions. Since the lithium battery does not contain any precious metals, the raw materials are very cheap, and there is a lot of room for price reduction. It should be the cheapest battery. The disadvantage is safety. Due to the good tightness of the metal casing, the battery may generate a hidden danger of explosion when it heats up during use. Li-polymer batteries (Li-polymer) are based on lithium batteries with polymer electrolytes instead of traditional liquid organic electrolytes. This polymer electrolyte can be used as an ion-conducting medium and as an isolation membrane. In addition, the reactivity with metallic lithium is extremely low, so it effectively prevents the easy burning and easy leakage of lithium batteries. And because the lithium ion polymer battery absorbs the liquid organic electrolyte on a polymer matrix, it is called a colloidal electrolyte. This electrolyte is neither a free electrolyte nor a solid electrolyte, which makes the lithium-lithium polymer battery not only The excellent performance of liquid lithium batteries can also be made into ultra-thin products of any shape and size, making it widely applicable and promising for development. In addition, it is safer than lithium batteries. If it heats up during use, it will only swell and not explode. Disclaimer: The articles published on this website are all from the Internet.
