What are the disadvantages of green batteries

Green and environmentally friendly batteries mainly include metal hydride nickel batteries, lithium ion batteries, alkaline zinc manganese dry batteries and fuel power batteries. Their specific disadvantages are as follows: The disadvantages of metal hydride nickel batteries: Metal hydride nickel batteries are composed of hydrogen ions and metals. It is composed of nickel, which has 30% more power storage capacity than nickel-cadmium batteries, and is lighter than nickel-cadmium batteries, has a much smaller memory effect than nickel-cadmium batteries, has a longer service life, and does not pollute the environment. But the disadvantage of Ni-MH batteries is that they are a bit more expensive than Ni-Cd batteries. Disadvantages of lithium-ion batteries: high price, the price of lithium-ion batteries is 1.5 times that of lead-acid batteries, can not discharge high current, only suitable for small and medium current electrical appliances. Disadvantages of alkaline zinc-manganese dry batteries: the internal structure of alkaline-manganese batteries is better than that of ordinary zinc-manganese batteries, and is more suitable for discharge reaction. The purity of raw materials used is higher than that of ordinary zinc-manganese batteries. But it is also expensive. Disadvantages of fuel power cells: Cost: Especially the initial construction cost is still higher than that of the generator, so it is difficult to promote. Although the cost is falling with the advancement of technology, there is still a way to go. The technical threshold is high: About the manufacturer , Sellers, and consumers must have certain skills or training, and it is not easy to reach the statement: Some pictures and content of articles published on this site are from the Internet.
