With the intensification of social aging, the travel problem of the elderly has gradually become a social problem. In order to facilitate the travel of the elderly and the disabled, the number of smart elderly electric scooters, electric wheelchairs, and electric stair climbers has increased, and the stock and demand of electric wheelchair batteries has also increased.
There are two types of batteries for electric wheelchairs on the market today, one is lead-acid battery and the other is lithium battery. Do you know the difference between them? Today I will give you a detailed explanation.
A lead-acid battery is a storage battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution.
In the charged state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the discharged state, the main component of the positive and negative electrodes is lead sulfate. In application, 6 single-cell lead-acid batteries are usually connected in series to form a nominal 12V lead-acid battery, as well as 24V, 36V, 48V and so on.
Lithium batteries are a class of batteries that use a non-aqueous electrolyte solution with lithium metal or lithium alloy as the negative electrode material.
In the past, because the chemical properties of lithium metal are very active, and the environmental requirements for processing, storage, and use are very high, so lithium batteries have not been used for a long time. With the development of modern science, lithium batteries have now become mainstream.
Let’s take a look at the advantages and disadvantages between lead-acid batteries and lithium batteries
1. In terms of energy, lithium batteries have high storage energy density, which has reached 460-600Wh/kg, which is 6-7 times that of lead-acid batteries;
2. From the perspective of service life, lithium batteries can be charged and discharged 1000 times, and usually have a service life of more than 6 years, while lead-acid batteries are about 500 times or less, and have a memory effect, its usually two years’service life.
3. In terms of weight, the weight of the lithium battery is about 1/6-1/5 of the lead-acid battery under the same volume;
4 From the perspective of environmental protection, lithium batteries do not contain or produce any toxic and harmful heavy metal elements and substances such as lead, mercury, cadmium, etc., whether they are produced, used or scrapped. And lead-acid batteries contain a lot of heavy metals. If handled improperly, it will cause serious pollution to the environment.
