Why is lithium battery the best choice at present?

As a means of transportation, the pursuit of new energy vehicles is nothing more than safety, power and endurance. In these respects, the biggest bottleneck of lithium battery vehicles is battery life, while the bottleneck of hydrogen fuel-powered battery vehicles is safety. Electric vehicle batteries have been developed for several generations, first are lead-acid batteries, then nickel-cadmium batteries and nickel-hydrogen batteries, and finally lithium batteries. This shows that lithium batteries are unique. In terms of energy density, specific power and cycle life, lithium batteries are currently the best choice. But the best lithium batteries still have a cruising range of about 500 kilometers, which is ideal, so they are not as good as gasoline-powered cars. The development of new batteries is an unpreventable task for new energy vehicles. The efforts of the new battery are multifaceted, including graphene batteries, metal-air batteries, lithium-sulfur batteries, supercapacitor batteries, and so on. Any breakthrough may revolutionize the automotive industry. But the most likely breakthrough so far is solid-state batteries, which should be confirmed in the laboratory, because big companies are racing against time to see who can process them first. So far, the most prominent example of fuel cell vehicles is Toyota's MIRAI, which has a cruising range of more than 500 kilometers. It can also be used as a socket for mobile power stations and trunks, enough for ordinary households to use for a week. The first is to store hydrogen at 700 atmospheres. If hydrogen leaks or explodes, the consequences will be disastrous. In addition, there are too few hydrogen refueling stations and there is no place to add hydrogen. The use of platinum as a catalyst is not a big issue. The problem with pure electricity is, where does the charge come from? Coal may also be used, so certain environmental protection is not seen. Hydrogen fuel-powered battery vehicles emit pure water, which is completely environmentally friendly, but the process of processing hydrogen is not environmentally friendly, so it is not clear who will win.
