What is the status of high-energy batteries?

In order for electric vehicles to achieve higher power performance, close to the current level of internal combustion engine vehicles, it is necessary to use high-energy batteries with particularly light weight and high energy density. Fortunately, in order to develop aerospace technology, people have developed some high-energy batteries for satellites and various aircraft, many of which can be borrowed from electric vehicles. The high-energy batteries currently being tested for automobiles include: nickel-cadmium batteries, nickel-zinc batteries, nickel-iron batteries, sodium-sulfur batteries, sodium-nickel-chloride batteries, lithium aluminum iron disulfide batteries (LAIS), zinc-air batteries, hydrogen fuel power Batteries, Ni-MH batteries, etc. The energy density of high-energy batteries is greater than that of lead-acid batteries, currently about 55-100 watt-hours per kilogram, and it is expected to reach more than 130 watt-hours. However, because they contain precious metals such as nickel and cadmium and other reasons, they are very expensive. For example, Ford’s sodium-sulfur batteries cost as much as 60,000 to 80,000 US dollars per set. According to foreign reports, the cheapest of several electric vehicles that are equipped with high-energy batteries is the mini-electric vehicle, which sells for more than US$10,000, which exceeds the price of ordinary mid-range cars. As for mid-range electric cars, the price is even more expensive, generally above $20,000. The TOWNACE electric car developed by Toyota is expected to sell for $70,000. Chrysler’s TEV electric car has a price tag of $120,000. These electric vehicles, which are more than twice as expensive as internal combustion engine vehicles of the same performance, are rarely bought by private individuals. Therefore, the approach of the United States and Japan is to first hand over electric vehicles to government agencies and public utilities for trial. Therefore, electric vehicles using high-energy batteries are currently difficult to popularize. In order to promote and popularize electric vehicles, it is necessary to find a relatively inexpensive high-energy battery. This problem has yet to be resolved. In addition, the current short reserve mileage and short charge and discharge life of various batteries must be further addressed.
