Lithium polymer batteries are widely used in a variety of fields because of their high energy density, lightweight, and environmentally friendly properties. However, the temperature can affect the performance of these batteries and reduce their discharge performance.
Lithium polymer battery is a high energy density, light weight, environmentally friendly battery, widely used in mobile devices, drones, power tools and other fields. However, since lithium polymer batteries belong to chemical power sources, temperature will affect the activity of internal lithium ions, and their discharge performance will inevitably be affected by temperature.
Under normal circumstances, the discharge performance of lithium polymer batteries will improve with the increase of temperature, but after exceeding a certain temperature, the discharge performance will decrease. When the temperature drops to an extremely low level, the discharge performance of the lithium polymer battery is further reduced. Therefore, for applications that require the use of lithium polymer batteries in extreme environments, such as polar exploration, aerospace, military and other fields, the requirements for low-temperature discharge performance are particularly important.
As a professional lithium battery manufacturer, UFINE is committed to providing lithium polymer batteries suitable for different temperature environments. We use advanced technology and high-quality materials to optimize the design and manufacture for different temperature discharge characteristics of lithium polymer batteries to meet the individual needs of customers.
First of all, in a low temperature environment, we select electrolyte components with high conductivity to improve the transport performance of lithium ions. At the same time, we also select electrode materials with small particle size and special coating treatment on their surfaces to increase and activate the interface of electrode reaction, reduce electrode polarization at low temperatures, and improve the low-temperature discharge performance of the battery. Our low-temperature lithium polymer battery can be discharged normally in -40°C environment, with good output performance and long life. For example, one of our company's low-temperature battery products 104050, its discharge temperature is -20°C to 60°C.
Secondly, in the high temperature environment, we use a cathode material with a small specific surface area and an electrolyte with high temperature components to reduce and passivate the reaction interface, while preventing structural collapse caused by transition metal dissolution, so as to improve the thermal stability and cycle life of the battery. Our high-temperature lithium polymer batteries can be discharged normally at high temperatures above 60°C, with strong adaptability and stability. For example, one of our company's high-temperature battery products 103450, its discharge temperature is 0°C to 80°C.
Therefore, in order to ensure the best discharge performance and service life of the lipo battery, the following points need to be observed during use:
1. Avoid leaving the battery in an extreme temperature environment for a long time, especially in a high-temperature environment, and place it at room temperature as much as possible.
2. When the battery needs to be stored for a long time, it should be placed in a dry, cool and room temperature place, and make sure that the battery charge is between 40% and 60%.
3. When operating the battery, you should follow the manufacturer's recommendations for use, do not overcharge or discharge, and avoid damaging the battery.
4. If you find that the battery is swelling or there is an abnormal situation, stop using the battery as soon as possible and dispose of it correctly.
Temperature is one of the important influencing factors of lipo battery discharge performance. While using the battery correctly, we also need to pay attention to keeping the temperature of the battery stable and avoiding damage to the battery caused by excessive temperature No. 2. Only proper use and maintenance of batteries can guarantee the best battery life and the best battery performance.
