What is the difference between the lithium battery and the lead-acid battery of an electric scooter?
There are currently lead-acid batteries and lithium batteries for electric scooter batteries on the market. What is the difference between lead-acid batteries and lithium batteries?
① Difference in price
Because lithium batteries have better heat dissipation and battery life, the production process from packaging to sealing is also very rigorous; therefore, the production cost is much higher than that of lead-acid batteries.
② Different battery materials
When a lead-acid battery is working, the main component of the positive electrode is lead dioxide and the main component of the negative electrode is lead; when it is charged, the main components of the positive and negative electrodes are lead sulfate.
When a lithium battery is working, the main component of the positive electrode is manganese dioxide, and the main component of the negative electrode is lithium metal or its synthetic metal. The battery uses a non-aqueous electrolyte solution; when it is charged, the positive electrode material of the lithium ion battery usually uses lithium Alloy metal oxide, graphite is used as negative electrode material, and battery using non-aqueous electrolyte.
③ Different memory effects
After the battery is left for a period of time, it enters the dormant state, and the capacity is lower than the normal value; lead-acid batteries will have a memory effect, and special methods and equipment are required to activate the battery and restore the normal capacity; the lithium battery has its own characteristics without memory effect. It only needs 3-5 normal charge and discharge cycles to activate the battery and restore normal capacity.
④ The difference in service life
The service life of lead-acid batteries is generally only two years, and the number of full charge and discharge cycles is generally within 300 times.
Lithium batteries have a service life of four to five years and are relatively durable, and the number of full charge and discharge cycles can exceed 500 times.
⑤ Different environmental protection efforts
Under the environmental protection policy, in order to ensure that the environment can reduce pollution, in the production, use and recycling of lead-acid batteries, there are pollution caused by improper handling, and lithium batteries are relatively complete due to their own packaging and sealing work. Will be relatively environmentally friendly.
