Which is better, lead-acid battery or lithium battery?

Compared with lead-acid batteries, lithium batteries have a higher average voltage and higher energy density. In other words, batteries of the same size have more lithium batteries. In addition, lithium batteries are relatively lightweight, easy to carry, and have a relatively long life. In addition, lithium batteries are more adaptable to high and low temperatures, are less affected by temperature, and are more environmentally friendly. Of course, lithium batteries also have three shortcomings. Their safety and stability are relatively poor. If they are not handled properly, they are prone to explosion risks. In addition, lithium batteries cannot be discharged at high currents, and processing requirements are high, and the cost is higher. Compared with lithium batteries, lead-acid batteries are relatively cheap and more acceptable to the public. In addition, the high-rate discharge performance of lead-acid batteries is better. The most important thing is that the recycling price of lead-acid batteries is higher than that of lithium batteries. However, lead-acid batteries also have their own shortcomings. For example, heavy metals are easy to cause environmental pollution; compared with lithium batteries, lead-acid batteries have lower energy density; and their service life is less than that of lithium batteries. Although lithium electric vehicles have many advantages, at present, lead-acid electric vehicles are the main factor. The important factor is imperfect technology. Although some lead-acid giants and electric vehicle giants have begun to develop lithium-ion products, they are Many companies are constantly exploring and exploring new fields, and the initial products may not reach the stage of maturity. Of course, some people may say that I can modify the lithium battery by myself, but what I want to say is that the modification is not that simple. Not only must the charger match, but also the motor power, voltage and other factors must be considered. Therefore, Personal modification is not recommended. In short, the emergence of lithium battery products is the realization of the progress of the electric vehicle industry, but to replace lead-acid batteries, the technology must reach a matching height, and at the same time, it must improve the cost performance, so that it can be accepted by more people. We all know that all parts of a car have a service life, and the battery is the same. The purpose of the battery includes: when the vehicle is ready to start, the battery is discharged to the starter, and the starter drives the flywheel and crankshaft to rotate, thereby starting the vehicle. When the engine power supply is insufficient or does not start, it supplies power to the electrical appliances in the car, such as the audio system, lighting system, etc. When the engine starts to supply power normally, the battery will collect and store electrical energy for future use. Nowadays, car batteries can be roughly divided into maintenance-free and ordinary batteries (non-maintenance-free). At present, most of the models sold on the market use maintenance-free batteries, while most Japanese cars use non-maintenance-free batteries, that is, ordinary batteries. Ordinary storage batteries are also called lead-acid batteries. Its electrodes are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The important advantage is stable voltage and low price; the disadvantage is frequent daily maintenance. Old-fashioned ordinary batteries generally have a life span of about 2 years, and it is necessary to regularly check the height of the electrolyte and add distilled water.
