What are the differences between lithium batteries and fuel power batteries?

Fuel power cell: A fuel power cell is a power generation device that directly converts the chemical energy in the fuel and oxidizer into electrical energy. It can convert straw, sawdust, algae and even organic fertilizers into electricity with the help of solar energy or waste heat. From the outside, it has positive and negative poles and electrolytes. It looks like a battery, but in fact it is not a battery. In other words, it is used immediately as soon as electrical energy is present. Generally, the active material of the battery is stored inside the battery, therefore, the battery capacity is limited. The positive and negative electrodes of a fuel power battery do not contain active materials, but are just a catalytic conversion component. Fuel power batteries have a wide range of uses, not only in military, space, and power plants, but also in motor vehicles, mobile equipment, and households. In addition, fuel power batteries use fuel and oxygen as raw materials; at the same time, there are no mechanical transmission parts, so there is no noise pollution and very few harmful gases are emitted. It can be seen from the perspective of energy conservation and ecological environment protection that fuel power cells are the most promising power generation technology. As the power source of electric vehicles, fuel-powered batteries have important characteristics: high energy conversion efficiency. The energy conversion efficiency of fuel power cells can be as high as 60% to 80%, which is 2 to 3 times that of internal combustion engines; it does not pollute the environment. The fuel of the fuel power cell is hydrogen and oxygen, and the product is clean water. It does not produce CO and CO2, does not emit sulfur and particulates, does not react at high temperature, and does not produce NOx. If the vehicle-mounted methanol reforming catalyst is used to supply hydrogen, only a trace amount of CO and less CO2 will appear. The most obvious advantage of fuel-powered batteries is that they don’t need a long charging process. It only takes a few minutes to add hydrogen. Toyota recently introduced a fuel-powered MPV with a charge of 5 minutes and a battery life of 1,000 kilometers. The foreground can be seen. Another advantage of fuel power cells is that they are pollution-free. Compared with the water pollution that may be caused by various toxic pollutants that appear after lithium batteries are scrapped, fuel power cells must have water, and there will be no problems in this area after the end of use. Lithium batteries: Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium batteries. Lithium batteries do not contain metallic lithium and are rechargeable. Lithium batteries have high voltage and light weight. The uniform voltage of a single battery can reach 3.7V or 3.2V. It is relatively equal to the series voltage of 2-4 nickel-hydrogen batteries or nickel-isolated batteries. If the customer requires the voltage of the battery to be used, it is easy to form a lithium battery pack by choosing a lithium battery, which is convenient and quick to increase the voltage of the lithium battery. Lithium batteries have a long service life. A lithium battery can be used for more than 6 years, as long as 9 years, if no accident occurs. The normal number of uses is more than 1000 times. If there is no accidental use, the number of uses can reach more than 1500. Adding a protective plate to the lithium battery during the processing of the lithium battery can make the lithium battery have an overcharge and overdischarge effect. The lithium battery itself has high power endurance, and the lithium battery selected for electric vehicles can achieve a high-efficiency charging and discharging capacity of 15-30C, so that the high-intensity start-up acceleration of the car can be accelerated.
