What is the difference between lithium-ion batteries and fuel power batteries?

High cost and huge hydrogen production process have become important obstacles to the growth of fuel power cells. Hydrogen is obtained through electrolysis or steam recombination. However, the cost of these two methods is quite high, and the cost required to produce the same quality of natural gas is 1/2 or even 1/3 of that of hydrogen production. The production cost of lithium-ion batteries is relatively low, and its repeated charging operation is very convenient. Compared with other portable energy sources, it has a higher cost-effectiveness. ②Situation Fuel power batteries and lithium-ion batteries have little impact on the situation. The former combustion product is water, which does not present the greenhouse gases generated after gasoline/diesel combustion. The discharge products of lithium-ion batteries are probably lithium oxide, lithium hydroxide, etc., which will not affect the situation. In addition, the lithium ion battery can be operated repeatedly. Based on the above points, these two types of batteries have become the most popular power source for electric vehicles. ③The polymer membrane is operated as the electrode in the material fuel power cell, which supports the hydrogen and oxygen reverberation to present electricity. Polymer membranes must be subjected to extraordinary processing to withstand high temperatures and machine stress. Lithium ions in lithium ion batteries can absorb charge, so the battery has the ability to store electricity. Lithium ion is very light, so it is the power source for the car's ambition. ④Potential Regardless of the fuel power battery or the lithium-ion battery, there is still a lot of room for improvement in related skills. If the cost of fuel power batteries can be reduced, they can truly be used as an alternative energy source for gasoline/diesel fuel. Regarding lithium-ion batteries, if their energy density can be further improved, and the cycle life can be longer, it is also a very good driving energy source. ⑤Safety temperature control is of great significance to the safety of lithium batteries. Regarding 3C small batteries, large-scale power lithium batteries have become more difficult to dissipate due to various factors such as cell layout, working methods and conditions. Therefore, the thermal management design of large-scale power lithium battery systems is very important. The organic solvents recovered from lithium batteries are flammable and have a low flash point. Thermal runaway caused by unsafe behavior can easily ignite flammable liquid components with low flash points and cause the battery to burn. Regardless of whether it is a fuel power battery system or a lithium-ion power lithium battery, the effect of the security disorder is extremely serious. However, if only from the perspective of system control, the author personally believes that fuel power batteries are relatively easier to control than lithium-ion power lithium batteries in terms of the controllability of factors affecting safety. Fuel-powered battery vehicles are another important bias of car batteries. When compared with lithium-ion batteries, the advantages and disadvantages of fuel-powered batteries are obvious. However, from a long-term perspective, it is not yet known which of fuel power batteries and lithium-ion batteries will be widely used in the future. Which battery will prevail in the future also depends on whether the bottlenecks of the two batteries can be handled well. The key technologies faced by lithium-ion batteries include energy density promotion, security, and heat management; fuel power batteries face high costs, Bottlenecks such as insufficient durability, hard cold start, and insufficient system integration optimization.
