LYT thermally conductive silicone pads in the field of new energy power batteries The heat-related problems of automotive batteries are key factors in determining their performance, safety, life and cost of use. First, the temperature level of lithium-ion batteries directly affects their energy and power performance in use. At lower temperatures, the usable capacity of the battery will rapidly degrade, and charging the battery at too low a temperature (e.g., below 0°C) may cause instantaneous voltage overcharging, resulting in internal lithium precipitation and short circuits. Secondly, the heat-related problems of lithium-ion batteries directly affect the safety of the battery. Defects in the manufacturing process or improper operation in the use process may cause local overheating of the battery, and then cause a chain of exothermic reactions, resulting in smoke, fire or even explosion and other serious thermal runaway events, threatening the life safety of the vehicle occupants. In addition, the working or storage temperature of lithium-ion battery affects its service life. The appropriate temperature of the battery is about 10~30°C, too high or too low temperature will cause a rapid decline in battery life. The large-scale power battery makes the ratio of its surface area to its volume relatively smaller, and the heat inside the battery is not easy to dissipate, and it is more likely that the internal temperature is uneven and the local temperature rise is too high, which further accelerates the battery degradation, shortens the life of the battery, and increases the total cost of ownership of the user. Battery thermal management system is one of the key technologies to cope with the heat-related problems of the battery and to ensure the performance, safety and life of the power battery Importance of thermal management of the battery 1, the battery energy and power performance: when the temperature is low, the usable capacity of the battery will be rapidly attenuated, and charging the battery at too low a temperature (e.g., less than 0 ° C) may lead to an instantaneous over-charging phenomenon, resulting in an internal short-circuit. 2, the safety of the battery: the lack of manufacturing links or the use of the process of improper operation may cause local overheating of the battery, and then cause a chain of exothermic reaction, resulting in smoke, fire or even burst and other serious thermal runaway events. 3, battery life: the appropriate temperature of the battery is about 10 ~ 30 ° C, too high or too low a temperature will cause a rapid decline in battery life. The large-scale power battery makes the ratio of its surface area to volume relatively small, the internal heat of the battery is not easy to dissipate, and it is more likely that the internal temperature is uneven, the local temperature rise is too high and so on, thus further accelerating the battery degradation and shortening the life of the battery. Battery thermal management system is to cope with the heat-related problems of the battery, the main functions include 1, heat dissipation: effective heat dissipation when the battery temperature is high, to prevent thermal runaway accidents; 2, preheating: preheating when the battery temperature is low, to enhance the temperature of the battery to ensure that charging and discharging performance and safety at low temperatures; LYT thermally conductive silica gel pads LYT thermally conductive silicone gaskets with a certain degree of flexibility, excellent insulation, compression, surface natural adhesion, and the ability to be used in the battery. LYT thermally conductive silicone gasket has a certain flexibility, excellent insulation, compression, surface natural viscosity, can fill the gap, complete the heat transfer between the heat-generating parts and the heat dissipation parts, and play the role of insulation, shock absorption and so on. Its excellent performance makes the heat from the heat device or the whole PCB conduction to the metal shell or diffusion plate, thus can improve the efficiency and service life of the heat electronic components.
