Lead batteries: a century-old technology at the heart of tomorrow's energy challenges

A historic invention

Since their invention by Gaston Planté in the mid-19ᵉ century, rechargeable lead batteries have established themselves as one of the pillars of the battery industry, despite the emergence of other technologies such as lithium. Their dominance of the markets is due to their low production cost, high reliability and, above all, their exceptional recyclability: today, 99% of end-of-life lead batteries are recycled.

Undeniable technical qualities

Although their energy density is lower than that of lithium batteries, they can boast many qualities, such as resistance to temperature variations, vibration and mechanical stress. This makes them an extremely reliable solution and the preferred choice for industrial and critical applications.

Multiple uses

They are particularly important for starting vehicles and their electrical systems. They are also found in forklift trucks and stationary solar energy storage. They also act as buffers (UPS), for example in emergency systems in hospitals or data centres, in the event of a power cut.

A key role in the energy chain

Lead batteries remain an essential link in the energy chain, combining durability, reliability and circularity.
