Lead-acid energy storage benefit analysis chart

Are lithium ion and lead-acid batteries useful for energy storage system?

Lithium-ion (LI) and lead-acid (LA) batteries have shown useful applications for energy storage system in a microgrid. The specific energy density (energy per unit mass) is more for LI battery whereas it is lower in case of LA battery.

Can lead batteries be used for energy storage?

Lead batteries are very well established both for automotive and industrial applications and have been successfully applied for utility energy storage but there are a range of competing technologies including Li-ion, sodium-sulfur and flow batteries that are used for energy storage.

What is the assumed cost reduction for lead-acid batteries?

A 15 percent cost reduction is assumed as lead-acid batteries gain penetration in the energy storage space. Lead-acid batteries are a mature technology, especially in the context of Starting, Lighting Ignition batteries used in automobiles.

Why do lead-acid batteries produce more impact than Lib batteries?

In general, lead-acid batteries generate more impact due to their lower energy density, which means a higher number of lead-acid batteries are required than LIB when they supply the same demand. Among the LIB, the LFP chemistry performs worse in all impact categories except minerals and metals resource use.

What is the cycle life of lead-acid batteries at 80% DoD?

The cycle life at 80 percent DoD of lead-acid batteries is in the 600 to 1,250 range. Assuming 350 cycles per year, this leads to a life in the range of 1.4 to 3.6 years.

What is the lifespan of lead-acid batteries?

The cycle life at 80 percent DoD of lead-acid batteries is in the 600 to 1,250 range. Assuming 350 cycles per year, this leads to a life in the range of 1.4 to 3.6 years. Table 4.15 shows the battery parameter data that were collected for this technology.
