Fuel cells compared with the performance of lithium-ion batteries

Source: 2020 - 04 - 12 21:05 hits: fuel cell and lithium batteries were compared a lot of people know little about the lithium battery, the difference between fuel cell and lithium battery is not very clear. How do you decide in the selection process? Below is the analysis of these two kinds of power supply. Fuel cell is the chemical energy in fuel and oxidant directly into electrical energy of a kind of power systems. It involved in chemical thermodynamics, electrochemistry, catalysis, materials science, electric power system and automatic control theory, has the advantages of high efficiency, less environmental pollution. Fuel cell has a wide range of applications, not only can be used in the fields such as military, aerospace, power plant, can also be used in motor vehicles, mobile equipment, household and other fields. The early development of fuel cell concentration on the specific application, such as military space and kilowatt above distributed generation. The world's first car use lithium ion battery is 2009 mercedes-benz Mercedes-benz S400 hybrid cars, more and more other carmakers have started to do. In the next 10 years, the world about 86% of the electric car will be powered by lithium-ion batteries. Lithium battery is the core of the electric vehicle power battery. Compared with the mature lead-acid batteries, lithium ion battery unit weight energy storage capability is strong, the price is low, basically nontoxic. Therefore, now in general tend to use new energy vehicles and lithium iron phosphate lithium manganese acid lithium battery. It has the high energy consumption, long service life, light weight, and the advantages of green environmental protection, but also facing some technical problems. Over the years, people have been trying to find a kind of both can efficient use of energy and polluting the environment, the method of fuel cell power generation technology is a kind of ideal. However, fuel cells are very complex, involving chemical thermodynamics, electrochemistry, catalysis, materials science, electric power system and automatic control and so on many disciplines related theory, there are still many technical difficulties! The development of lithium ion battery is facing the problem of low degree of charging infrastructure. With the rise of tesla motors, the improvement of the national charging infrastructure system will gradually improve, this problem can be solved.
