Lead-acid batteries have been powering our lives for over a century. These rechargeable batteries employ a simple yet efficient chemical reaction using lead plates and sulfuric acid electrolyte. They offer significant advantages such as high energy density, versatility, and low maintenance requirements. Despite advancements in battery technologies, lead-acid batteries continue to dominate applications in uninterruptible power supply (UPS), automotive industries, and off-grid solar systems.

A hundred years of inheritance and durability: the long history of lead-acid batteries The invention of lead-acid batteries dates back to 1859, when French physicist Gaston Planté invented them. After more than 160 years, lead-acid batteries are still one of the most widely used types of batteries in the world, which demonstrates their technological maturity and reliability.

As the global demand for sustainable energy solutions continues to grow, lead-acid batteries, as a mature and cost-effective energy storage technology, are ushering in a series of technological innovations to adapt to the development of new energy markets. ​

Technological innovation: improving performance and efficiency Advances in technology have significantly improved the performance of lead-acid batteries. The new lead-carbon battery combines the advantages of lead-acid batteries and supercapacitors, providing faster charging and discharging speeds and higher energy efficiency. In addition, the lifetime and reliability of lead-acid batteries have been enhanced by optimising the battery management system.
