The lithium-ion batteries have fewer environmental impacts than lead-acid batteries for the observed environmental impact categories. The study can be used as a reference to decide how to substitute lead-acid batteries with lithium-ion batteries for grid energy storage applications. 1. Introduction
Finally, for the minerals and metals resource use category, the lithium iron phosphate battery (LFP) is the best performer, 94% less than lead-acid. So, in general, the LIB are determined to be superior to the lead-acid batteries in terms of the chosen cradle-to-grave environmental impact categories.
In energy storage, lithium-ion batteries and lead-acid batteries dominate the market. Whether for solar systems, electric vehicles, or industrial equipment, choosing the right battery type impacts performance, cost, and long-term efficiency.
1. Core Differences Between Lead-Acid and Lithium Batteries Lithium-ion (e.g., LiFePO4): 3,000–5,000 cycles, retaining 80%+ capacity after 2,000 cycles. Lead-Acid: 300–500 cycles, with capacity often dropping below 50% after 150 cycles. Cost Insight: Lithium’s upfront cost is 2–3× higher, but its lifespan reduces long-term expenses by 40–50%.
