Many say the fate of home-made lead-acid batteries for electric bikes is coming to an end, after new national standards for electric bikes set some hard rules. In recent years, lead-acid battery as a hundred years old, constantly by the battery industry of the new lithium ion battery, staged two songs of ice and fire. So what are the differences between lithium-ion batteries and lead-acid batteries?

In terms of components. Under the same capacity, the lead-acid battery is 3~5 times the lithium-ion battery package, so the volume of the lead-acid battery is also larger, and the new national standard of electric bicycle weight is not more than 55 kg, will make the lithium-ion battery easier than the lead-acid battery components.

Lead-acid batteries are functionally identical to lithium-ion batteries

The first is the battery's two most fundamental parameters: voltage (V) and capacity (AH).

Although lead-acid batteries have a 2V cell and lithium-ion batteries have a 3.7V cell, both can be used in series, For example, we hear the 60V lithium ion battery in our daily life is 16 lithium ion battery single grid series for 59.2V (3.7V*16=59.2V), 60V lithium ion battery pack is connected with 5 12V lithium ion batteries in series. On the voltage, lithium ion battery and lead-acid battery is no different, 60V battery lead-acid and 60V battery lithium if do not consider their internal material, can be completely consistent in function, lithium ion battery 60V and lead-acid battery 60V on the battery voltage needs of users is exactly the same.

In terms of other sedation, lead-acid batteries and lithium-ion batteries can also be controlled by the amount of internal chemicals, a 100AH lead-acid battery and a 100AH lithium-ion battery their capacity size is the same (with 60 catties of iron and 60 catties of cotton).

There is a world of difference between acid batteries and lithium-ion batteries

Above is the battery from the two basic characteristics of lead-acid battery and lithium-ion battery, they look very similar, we are doing the same job, pay the same labor. But they are very different, lead-acid battery lithium-ion battery you can't mix, let alone lead-acid battery 18650 (because 18650 is a technical term for lithium-ion battery).

The difference between lead-acid battery and lithium-ion battery is important to the present internal information is not the same, so they appear in the chemical equation of electric energy chemical principle is different, lead-acid battery is critical through metal lead and sulfuric acid to react, lithium-ion battery is critical through lithium alloy and graphite to react. This fundamental reason leads to a significant difference in the function and cost of lead-acid batteries, which in turn leads to a significant difference in the price of lead-acid batteries and lithium-ion batteries.
