Lithium battery is going to replace Lead Acid Battery Technology.

Lithium batteries will replace Lead Acid Battery Technology, which is the topic to discuss here. The Latest Lithium battery Technology will change the paradigm of storage solutions in the long run, and people are using different type of Lead Acid batteries for storage, which is SMF, Tubular, or SMF technologies. challenges and limitations.

The first limitation is cycle life, as lead-based batteries cannot match the Cycle life of a Lithium battery. In literal terms, the Lead Acid battery life is defined by various parameters. One is refilling the battery water, which is a big challenge for the user as they cannot fill it in time. What kind of water they are supposed to fill is another challenge as they fill with any RO or normal water, which destroys even the normal cycle life. The Gel battery has the challenge of higher temperatures, so the performance goes down if the temperature is higher than a certain defined value.

Lithium battery is a very stable technology that has been proven for almost two decades now, especially LifePO4, a very well-accepted technology. The cycle life varies on the good BMS, which regulates proper charging and discharging, so the battery has minimal heating inside. We can get anywhere between 1500 to 4000 cycles. In contrast, Lead Acid cannot perform more than 400-500 cycles. So, there is a clear edge in terms of cycle life.

Another important factor is capacity at different discharge levels. So Lead Acid batteries are generally designed at C20 design, meaning you can discharge 5% of the storm, and only you will get rated capacity. This is also unavailable as making Lead Acid is crude, and consistent power is challenging. If you discharge at the 50% rating of the battery, generally speaking, it gives you 50% of its rated capacity. Lithium is a C1 battery, so the capacity remains 100% at any load. This is a big difference when we use these batteries for storage purposes like inverters, UPS, and Solar solutions; the Lead Acid backup time can’t match the Lithium battery pack.

Another major challenge is the cell balancing option available in the Lithium battery pack in the BMS, which is one reason that battery life can be achieved as the Lead Acid battery has six cells that cannot be balanced as there is no provision inside the battery. If we need to operate higher DC voltages, then we need the balancing between the batteries, and that’s also not done by the user. So if we need to put 120 V DC, then we need 10 Lead Acid batteries, which take up a big space and can’t be balanced with each other, and the Internal cells of each battery pack are also impossible. The connecting wires take a longer route, which becomes another challenge as each battery takes its own space, and we need to keep them at a distance, which creates wire losses. The Lithium is a single pack and one-fourth of the size of the Lead Acid battery bank. So there are hardly any losses between the battery cells, which keeps minimum losses and cell balancing for each cell is balanced through the BMS. So, in the end, there is no comparison between Lead Acid batteries and Lithium batteries. The industry will be revolutionised in the next five years, and Lead Acid will be out of the storage business. So all the storage devices like Inverters, UPS, Solar inverters, Lift inverters/UPS, Energy Storage Systems, etc., where Lead Acid batteries like Tubular, VRLA, Gel, etc., will be replaced by Lithium battery in future.
