Is an electric bicycle better with a lithium battery or a general battery?

Needless to say, in many places, lithium batteries are stronger than lead-acid batteries. For the same capacity, the volume of lithium batteries is less than 70% of lead-acid batteries, and the weight of lithium batteries is less than 40% of lead-acid batteries, so lithium batteries can do The range is much longer than that of lead-acid batteries. The charging and discharging cycle of lithium batteries is more than 600 times. Lead-acid batteries are relatively small in capacity and large in size, and their service life is much shorter than that of lithium batteries. The charging and discharging cycle cycles are also reduced, and the lifespan is shorter. It may be broken after a little more than a year. 2. Price The price of lithium batteries is about 2-3 times that of lead-acid batteries. Normally, an electric car with a lead-acid battery costs a few hundred yuan to replace the battery, while a lithium battery can cost thousands of yuan at every turn. This is related to the average wage earner. In other words, it's not a small expense. And the lithium battery has almost no recovery value. The lead-acid battery is broken, and it can be replaced with a little money. In this way, although the lithium battery has a long life, it does not take up much compared to the recycling of lead-acid batteries. It's cheap. 3. Reliability Although the lithium battery has a large capacity, it is too vivid, delicate, slightly disturbed, and may be broken. Therefore, a reasonable battery management system is required, and there are requirements for temperature and vibration. If the design is not good, there may be problems with the quality of the battery cell, or improper use, or it may cause fire and explosion. For ordinary people, it is indeed a scare thing. In addition, the lithium battery cannot be discharged at a high current, that is, the instantaneous output current cannot be so large, so the advantages of power are not obvious. In contrast, in the use of lead-acid batteries, it is as if many people are arbitrarily connecting in series and parallel connections. There is no big problem. If there is a drop in capacity, add some water at will, or make corrections, and regain energy, and there is no need to worry about fire and explosion (Of course there may be problems with overcharging) 4. Convenience If you can’t buy a tram to ride, you can’t expect an engineer to follow your butt to help you. The lead-acid battery is broken, just buy the battery and replace it at will, at most It's just not far. Each lithium battery has a different management system. If it is broken, you really owe it to repair. This thing is risky, so you often need to send it back to the manufacturer for repair or replacement. Not to mention the cost of travel, just delay, it is still a piece Troublesome work. V. Looking forward, ordinary people will choose products from the perspective of cost performance. Lithium batteries are inferior to lead-acid batteries, which is the reality after considering various factors. Look at those low-speed electric cars equipped with lead-acid batteries. They are also very prosperous. The regular so-called new energy cars do not sell well without them. This is also the truth. However, after the new national standard is launched, shopping malls will be changed entirely from the supply side. Only small and light-weight ones can be used on the streets, so lithium batteries should usher in a new stage of development.
