The comparison between lithium batteries and lead acid batteries is as follows:
1. The rated voltages are different: single lead-acid battery 2.0V, single lithium battery 3.6V.
2. Different energy densities: 30WH/KG lead acid battery, 110WH/KG lithium battery.
3. The lifespan is different: lead-acid batteries have an average lifespan of 300-500 times, and lithium batteries have a lifespan of more than a thousand times.
4. Different charging methods: The charging method of lithium batteries is relatively fixed, using the voltage limiting and current limiting method, that is, a limiting threshold is given to both the current and voltage, while there are more charging methods for lead acid batteries.
Characteristics of lithium batteries
1. Lithium batteries are small in size and largee capacity: Lithium batteries are much smaller and are usually lead acid. acid batteries. At the same time, the weight of lithium batteries is much lighter than that of lead-acid batteries. However, the capacity of lead-acid batteries is only about 1/6. is much larger than that of lead-acid batteries, which means it can store more electricity.
2. Lithium battery has a long life: Since the capacity of lithium battery can store more energy, the battery life is much longer. At the same time, the light weight of the lithium battery itself consumes. less energy, which is one of the main reasons why all electric vehicles now use lithium batteries.
