Nowdays, Traditional lead-acid batteries are being gradually replaced, and lithium batteries, as the current main electric energy source, are rapidly entering our lives.
Today, let’s talk about the difference between lithium batteries and lead-acid batteries!
1. Main ingredients
The main components of lead-acid batteries are lead and acid. During use, a large amount of heavy metal lead and acid mixture will be produced. Improper storage will cause environmental pollution. The main components of lithium batteries are lithium and some other light metals. From the perspective of environmental protection, lithium batteries are better.
2. Energy density
The energy density of lithium batteries is about 160WH/KG, and the energy density of lead-acid batteries is only 40WH/KG. If the battery compartment of the lead-acid battery of an electric tricycle is filled with lithium batteries, the cruising range will be doubled, and the weight is only 2/3 of the lead-acid battery.
3. Life comparison
There is no doubt about the power and battery life of lithium batteries. Anyone who has used lead-acid batteries knows that the capacity of lead-acid batteries will be reduced by about half after one year of use, and the power and battery life will be greatly reduced. The average life of lithium batteries is about three years, which is more durable.
4. Price difference
The most important thing is that lithium batteries not only have good performance, but also the price is king. Taking a certain brand of 72V20AH battery as an example, the prices of lithium batteries and lead-acid batteries are 1968 yuan and 1238 yuan respectively. The average cost of lithium batteries is 656 yuan/year, while the average cost of lead-acid batteries is 1238 yuan/year.
5. Safety performance
However, the higher the energy density of lithium batteries, the lower the stability.
