There are differences between lead-acid batteries and lithium iron phosphate batteries in multiple aspects:
1. Energy density
Lithium iron phosphate batteries have a higher energy density. This means that under the same volume and weight, lithium iron phosphate batteries can store more electrical energy.
For example, an electric vehicle using lithium iron phosphate batteries can travel longer distances compared to an electric vehicle using lead-acid batteries.
2. Cycle life
The cycle life of lithium iron phosphate batteries is usually much longer than that of lead-acid batteries. Lithium iron phosphate batteries can undergo thousands of charge and discharge cycles, while lead-acid batteries typically only have a few hundred cycles.
Taking electric bicycle batteries as an example, if lithium iron phosphate batteries are used, they may not need to be replaced for 7-8 years; Lead acid batteries may need to be replaced more frequently. The lifespan of lithium iron phosphate batteries is approximately 4-5 times that of lead-acid batteries
3. Charging speed
The charging speed of lithium iron phosphate batteries is relatively fast, and they can be charged in a short time.
For example, some new energy vehicles use lithium iron phosphate batteries, which can be charged to over 80% in just a few minutes.
4. Security
The safety of lithium iron phosphate batteries is relatively high, and the risk of fire and explosion is low in situations such as high temperature, overcharging, and short circuit.
In contrast, lead-acid batteries also have certain safety hazards when used improperly or malfunctioning, but overall safety is slightly inferior to lithium iron phosphate batteries.
5. Environmental friendliness
Lithium iron phosphate batteries are relatively more environmentally friendly and have less pollution to the environment.
Improper handling of lead and other substances in lead-acid batteries can cause significant environmental pollution.
6. Cost
The cost of lead-acid batteries is usually low, which makes them still have a certain market in some cost sensitive application scenarios.
The cost of lithium iron phosphate batteries is relatively high, but their performance advantages are reflected in some high-end applications
