Do you know the difference between lead-acid batteries and lithium batteries?

Lead-acid battery and lithium battery Lead-acid battery and lithium battery In the previous article, Xiao Bin explained the basic knowledge of lead-acid battery and lithium battery respectively. So what are the differences between lead-acid battery and lithium battery? Can the battery and lithium battery switch freely? Let's take a closer look today. First, lead-acid batteries and lithium batteries are functionally the same. The first is the two basic parameters of the battery: voltage (V) and capacity (AH). Although the single grid voltage of lead-acid batteries is 2V and the single grid voltage of lithium batteries is 3.7V, they can be used in series. For example, the 60V lithium battery we hear in our daily life is 16 59.2v (3.7v*16u003d59.2v) single-grid lithium batteries, and the 60V lithium battery pack is connected in series with 5 12V lithium batteries. In terms of voltage, lithium batteries are no different from lead-acid batteries. 60V lead-acid batteries and 60V lead-acid batteries can be completely the same in function regardless of their internal materials. Lithium batteries 60V and lead-acid batteries 60V have complete battery voltage requirements. the same. In terms of capacity, lead-acid batteries and lithium batteries can also be controlled by the amount of chemical substances present inside. The capacity of a 100AH u200bu200blead-acid battery and a 100AH u200bu200blithium battery are the same (equivalent to 60kg of iron and 60kg of cotton). Second, there are essential differences between lead-acid batteries and lithium batteries. These are the two basic characteristics of batteries, lead-acid batteries and lithium batteries. They look like we are all doing the same work and paying the same labor. But they are very different. Lead-acid batteries and lithium batteries cannot be mixed, let alone lead-acid batteries 18650 (because 18650 is a term for lithium batteries). The important difference between lead-acid batteries and lithium batteries is that the internal information is different, so the chemical equations of chemistry are also different. Lead-acid batteries are mainly through the reaction of metallic lead and sulfuric acid, and lithium batteries are mainly through lithium alloy and graphite. The reaction to the attack. This fundamental reason has led to significant differences in the functions and costs of lead-acid batteries, which in turn led to significant differences in prices between lead-acid batteries and lithium batteries. 3. The advantages and disadvantages of lead-acid batteries and lithium batteries. In terms of function, lithium batteries have a longer lifespan than lead-acid batteries of the same voltage and capacity, but lead-acid batteries have better large-current discharge functions. Lithium batteries are more expensive, and lead-acid batteries Batteries are cheaper. As for the two, we cannot simply say that lead-acid batteries or lithium batteries are better. Both have their own advantages and disadvantages. The specific advantages and disadvantages and characteristics of the two are as follows: 4. Can lead-acid batteries and lithium batteries be used in common? Let us be right about the above three points. The commonalities and differences between lead-acid batteries and lithium batteries have been partially understood, so now your question must come: we know the truth, but in actual use, can lead-acid batteries and lithium batteries be used in common? First of all, the answer is yes. Lead-acid batteries and lithium batteries can be used in common, but in the process of refitting lead-acid batteries with lithium batteries or using lead-acid batteries to replace lithium batteries, we should also use the conditions on the spot to adjust. For example, if you use a 48V lead-acid battery, you will use a 48V lithium battery instead of a 60V lithium battery. After lead-acid batteries and lithium batteries, it is recommended that you also want to replace the corresponding charging methods. Although it is usually said that lithium battery chargers can be lead-acid batteries, because lead-acid batteries and lithium batteries have different charging capabilities, the charger function The parameters are also different. Generally speaking, the charging current of the lithium battery charger is smaller than that of the lead-acid battery charger. Therefore, if you use the lithium battery charger to charge the lead-acid battery, it will easily cause the battery to swell. Lead-acid battery chargers charge lithium batteries, and the charging time will be very long. Friends, do you know the difference between lead-acid batteries and lithium batteries?
