The main differences between lead-acid batteries and lithium batteries are different lifespan, number of charge and discharge cycles, volume and weight.
1. Different lifespans
The lifespan of lead-acid batteries is generally about 2 years, and lithium batteries have strong durability and are used. The lifespan is generally 4 to 5 years.
2. The number of charge and discharge cycles is different
Lead-acid batteries are generally fully charged and discharged in 400 times and have memory for; lithium batteries are fully charged and discharged 500 times and no memory.
3. Different sizes and weights
Typically, lead-acid batteries weigh between 16 and 30 kg and are generally larger than lithium batteries; -3 Kilogram, the volume is relatively smallt.
How lead-acid batteries and lithium batteries work:
Lithium-ion batteries are characterized by their lightness and ease of transport. Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution.
Lead-acid batteries can store limited electrical energy and use it in appropriate locations. Its working principle is to convert chemical energy into electrical energy. It uses a lead plate filled with sponge lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and 22 to 28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy and during discharging, chemical energy is converted into electrical energy.
Differentweight, 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 means that the capacity oflithium batteries is larger under the same volume.
