What is the difference between lead acid batteries and lithium batteries?

Different weights, different lifespans, different battery levels and different capacities.

1. His weight is completely different. The weight of lithium battery is only 1/4 of that of lead-acid battery of the same capacity, and the size is also greatly reduced, only 1. /3 of lead-acid battery. This gives lithium batteries a clear advantage in terms of portability.

2. The lifespan of the two is different. Lead-acid batteries are typically used for around 2 years, while lithium batteries are more durable and can typically be used for 4-5 years.

3. The number of charging cycles of lithium batteries far exceeds that of lead-acid batteries, reaching more than 500 times.

4. From the perspective of battery power, lithium batteries have higher average voltage and higher specific energy, which meanse that the capacity of lithium batteries is greater under the same volume.

What is the difference between lithium batteries and lead acid batteries?

The differences between lithium batteries and lead acid batteries are safety , environmental protection and price. , and self-discharge The rates are different and the service life is different.

1. Different safety profiles

Different materials (lithium manganese oxide, lithium iron phosphate) for power lithium batteries have different safety profiles. quite mature and its safety is higher than that of lithium battery.

2. Environmental protection is different

Lithium batteries do not cause pollution, while lead-acid batteries are polluted by heavy metals. Therefore, electric vehicles using lead-acid batteries will always pollute the environment. environment.

3. Different prices

The price of lithium batteries of the same capacity on the market is more than twice that of lead-acid batteries, which is why electric vehicles using lithium batteries are relatively expensive .

4. Different self-discharge rates

The monthly self-discharge rate of lithium batteries is less than 3%, while the monthly self-discharge rate of lead-acid batteries is 15%. ~30%. There is a big difference between the two.

5. Different lifespan

Currently, lithium iron phosphate can be charged 1,500 times without memory effect. After charging 1500 times, its storage capacity is about 85%, while the storage capacity of lead-acid batteries is about 500 times. The storage capacity will also be significantly reduced, and the memory effect will be obvious. Therefore, the battery life of electric vehicles using batteries atlithium will last longer.

The difference between lithium batteries and lead acid batteries is: different weight, different lifespan and different battery capacity.

1. The weight is different. The weight of the lithium battery is only 1/4 of that of the lead-acid battery of the same capacity, and the volume is only 1/3 of that of the lead-acid battery. lead acid battery of the same capacity.

2. The lifespan is different. The lifespan of lead-acid batteries is typically around 2 years, while lithium batteries are more durable, with a lifespan of 4-5 years. The lead-acid battery cycle is generally fully charged in 300 times, while the lithium battery is fully charged and discharged more than 500 times.

3. The battery capacity is different compared to lead acid batteries, the average working voltage of lithium batteries is higherlifted and its specific energy is higher.It is said that for rechargeable batteries of the same size, lithium batteries have greater capacity.

Applications of lithium batteries:

Lithium batteries are widely used in energy storage systems such as hydropower, l thermal energy, wind energy and solar power plants. , and uninterrupted postal communications and telecommunications Power supplies, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields.

Lithium-ion batteries have been widely used in portable devices such as laptops, cameras and mobile communications due to their unique performance advantages. The developed large-capacity lithium-ion battery was tested in electric vehicless and has become one of the main sources of energy for electric vehicles in the 21st century. It will also be used in satellites, aerospace and energy storage.

With the shortage of energy and the pressure of environmental protection in the world. Lithium batteries are widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has promoted the development and application of lithium battery industry.
