Foam carbon in LED lamps:
One of the most important characteristics of foamed carbon is the high thermal conductivity at low density. Compared to conventional heat capacity materials (such as copper and aluminum), the specific thermal conductivity of foamed carbon is seven times higher. In addition, the foamed carbon has a relatively low coefficient of thermal expansion and a stable size, and is therefore suitable for application under high temperature working conditions. In addition, the foamed carbon has a network structure that determines the material is isotropic to thermal diffusion. After the graphitization, the thermal conductivity of the foamed carbon is very high in the range of 50 to 200 W/M.K. The thermal conductivity of foamed carbon is significantly different in different directions. Comparing the thermal conductivities of two orthogonal directions, the thermal conductivity perpendicular to the XY plane is 3.5 times parallel to the XY plane under all temperature conditions.
The thermal and thermal properties of foamed carbon materials are used in heat dissipation materials for products such as LED lamps and computer chips.
 
 Commercial high-power LEDs have a luminous efficacy of only 15% to 30%, and most of the rest of the energy is converted into heat. If heat is not effectively discharged, it will have serious consequences. High temperature will reduce the luminous flux of LED and its luminous efficiency, cause red light shift and color cast of light, and cause undesirable phenomena such as aging of the device. The most important thing is to exponentially reduce the life of LED. The data shows that the temperature rises by 10 °C, the life expectancy is reduced by half. The foamed carbon has a higher specific heat capacity, porosity, and opening characteristics, which accelerates the thermal diffusion and can greatly extend the service life of the LED.
 
 
Foam carbon is used as battery electrode material
Since foamed carbon has good electrical conductivity, large specific surface area, and good stability, it is a good current collector material for battery electrodes, and foam can be used for battery electrodes and fuel cell electrodes.
Foam carbon is used in lead-acid batteries instead of lead alloy grids. Foamed carbon has a good three-dimensional communication opening network structure, which can be directly used as a negative electrode current collector material for lead-acid batteries, and is surface-plated.
It can be used as a positive current collector after treatment. The use of foamed carbon current collector material can effectively improve the utilization rate of active materials in lead-acid batteries. Under the conditions of discharge currents of 1.20C and 1.10C, the active material utilization rate of foamed carbon anodes is 15% higher than that of lead grid anodes. %. Improves the partial charge cycle performance of the battery while reducing the amount of lead used in the battery. To a certain extent, it solves the problems of low lead capacity and short cycle life of lead-acid batteries.
