Which is better, fuel battery or lithium battery?

Many people know very little about lithium batteries, and they don't know the difference between fuel cells and lithium batteries. How do you decide during the selection process? Let's analyze the two power supplies for everyone.

A fuel cell (FuelCell) is a power generation device that directly converts chemical energy present in a fuel and an oxidant into electrical energy. It involves theories of chemical thermodynamics, electrochemistry, electrocatalysis, materials science, power system and automatic control, and has the advantages of high power generation efficiency and less environmental pollution. Fuel cells are widely used in military, space, and power plants, as well as in automobiles, mobile devices, and residential homes. Early fuel cell development focused on specialized applications such as military space and decentralized power generation above kilowatts.

The world's first car to use lithium-ion batteries is the Mercedes-Benz 2009 S400 hybrid, and more and more other car manufacturers are starting to do the same. It is understood that in the past 10 years, about 86% of the global electric vehicles will use lithium-ion batteries for power supply. The lithium battery is the core power battery for electric vehicles. Compared with well-developed lead-acid batteries, lithium-ion batteries have high energy storage per unit weight, are inexpensive, and are basically non-toxic. Therefore, new energy vehicles nowadays generally prefer lithium iron phosphate and lithium manganese oxide batteries. It has the advantages of high energy, long service life, light weight, environmental protection, but also some technical problems.

For many years, people have been striving to find energy utilization methods that have higher energy efficiency and do not pollute the environment, and fuel cells are ideal power generation technologies. However, the fuel cell is very complicated, involving many disciplines related to chemical thermodynamics, electrochemistry, electrocatalysis, materials science, power system and automatic control, and many technical difficulties have not been broken! The development of lithium-ion batteries faces the problem of low reliability of the charging infrastructure. With the rise of Tesla Motors, the perfection of the national charging facility system has gradually improved, so that the problem can be solved.
