Are lithium batteries better than lead-acid batteries? You will understand by looking at this

pxid 2021-01-05 46 times

As the main source of electrical energy for vehicles, batteries occupy a large market in the industry. Now industrial design companies use more efficient lithium batteries, and lead-acid batteries as the cornerstone of the battery industry have been eliminated ?

Let's take a look at the difference between lithium batteries and lead-acid batteries?

The main components of lithium batteries are lithium metal or lithium ion materials, which have active chemical properties and high energy density. Power batteries on the market are mainly ternary lithium batteries and lithium iron phosphate lithium batteries. The lithium batteries for electric vehicles are mainly 18650 batteries developed by Panasonic. The cycle times are 800-1000 times and the average service life is 3-4 years. . A set of 48V20Ah lithium batteries weighs 8-10 kg.

The main raw materials of lead-acid batteries are lead plates and sulfuric acid electrolyte, which are converted into electrical energy through chemical energy to power electric vehicles. The number of cycles (full charge and discharge) of ordinary lead-acid batteries is between 500-600, and the service life is about In about 2 years, a set of 48V20AH lead-acid batteries weighed about 27 kg.

With the same capacity, lithium batteries have the advantages of lighter weight, long service life, short charging time, more portable use, and large operating temperature range. In addition, lithium batteries have a lower self-discharge rate and are not easy to lose electricity.

However, the high temperature resistance of lead-acid batteries is better than that of lithium batteries, because the battery capacity is larger, so lead-acid batteries have longer battery life.

Judging from the current market, lithium batteries still dominate the mainstream, and are more suitable for light transportation tools such as electric scooters, balance bikes, and electric bicycles. Industrial design companies use more lead-acid batteries in automobiles, traditional electric vehicles, and motorcycles. And other industries.
