The energy density of lithium-ion batteries falls under the range 125-600+ Wh/L whereas, for lead acid batteries, it is 50-90 Wh/L. This drastic variation is due to the fact that lead acid batteries are much heavier than lithium-ion batteries, which in turn results in less energy density. Lead acid batteries also need more space to fit in.
Lithium-ion batteries are lighter and more compact than lead-acid batteries for the same energy storage capacity. For example, a lead-acid battery might weigh 20-30 kilograms (kg) per kWh, while a lithium-ion battery could weigh only 5-10 kg per kWh.
Disadvantages: Heavy and bulky: Lead acid batteries are heavy and take up significant space, which can be a limitation in specific applications. Limited energy density: They have a lower energy density than lithium-ion batteries, resulting in a lower capacity and shorter runtime.
Lead acid batteries comprise lead plates immersed in an electrolyte sulfuric acid solution. The battery consists of multiple cells containing positive and negative plates. Lead and lead dioxide compose these plates, reacting with the electrolyte to generate electrical energy. Advantages:
Yes. Depending on your target applications, you can substitute lead-acid batteries with lithium-ion batteries. Before swapping the batteries, ensure the lithium-ion battery is well-matched to the voltage system and the charging system. In some cases, you will need an external charger that is compatible with the lithium battery.
When it comes to humidity exposure, lithium-ion batteries have better resilience than lead-acid. Lithium-ion batteries have a robust casing that is completely sealed, therefore, moisture does not get to the internal components of the battery.
