What are the advantages of lead-acid batteries?

2021-03-05

1. Super long life
The cycle life of lead-acid batteries is about 200 times, and the highest is 300 times. The lithium-ion battery has a cycle life of more than 300 times, and it can be used for standard charging (5 hours rate) up to 500 times or even more than 1000 times. Lead-acid batteries can be used for 1-1.5 years at most, while lithium-ion batteries will be used for 3 years under the same conditions.
2. Safe to use and good performance
Lithium-ion batteries completely solve the potential safety hazards of lead-acid batteries. Lead-acid batteries will explode under a strong collision, posing a threat to the lives of consumers. The lithium-ion battery does not explode under strict safety tests.
2. No memory effect
When the rechargeable battery is always fully charged and not discharged, the capacity will quickly fall below the rated capacity value. This phenomenon is called the memory effect. The lithium-ion battery does not have this phenomenon. No matter what the state of the battery, it can be charged and used at any time, without having to discharge it before charging.
4. Small size, light weight and long time
The volume of a lithium-ion battery of the same specification and capacity is 2/3 of the volume of a lead-acid battery, and its weight is 1/3 of that of a lead-acid battery.
5. expensive
Electric vehicles with lithium-ion batteries are twice as expensive as electric vehicles with lead-acid batteries.
6.green and environmental protection
Lead-acid batteries contain a large amount of lead in electric vehicles. If they are disposed of improperly, they will pollute the environment. Lithium materials do not contain any toxic and harmful substances. They are regarded as green and environmentally friendly batteries in the world. There is no pollution in production and use, which has become a hot research topic.
