Why Lead-Acid Batteries Still Matter in Modern Energy Storage

Did you know that lead-acid batteries account for over 50% of the global energy storage market? Despite newer technologies like lithium-ion, their affordability and reliability make them indispensable. Let''s break down why they''re still a top choice—and where they shine.

Core Materials: What''s Inside a Lead-Acid Battery?

Lead-acid batteries rely on a simple yet effective design:

• Lead dioxide (PbO₂): Forms the positive plate.
• Sponge lead (Pb): The negative plate material.
• Sulfuric acid (H₂SO₄): Electrolyte enabling ion transfer.

"The chemistry is tried-and-true—like a dependable workhorse. It''s why they''re used in everything from cars to solar farms."

Top Applications Across Industries
