From lead sheets to smart batteries, the road to scientific and technological innovation of lead-acid batteries is a long and challenging journey. The following is a detailed explanation of the process.
First, the origin and development of lead-acid batteries
Lead-acid batteries, as one of the earliest industrialized batteries, have experienced more than 160 years of development history since their invention in 1859. With its comparative advantages of low cost, mature technology, stability and reliability, high security and good resource reuse, it plays a basic supporting role in the fields of transportation, communications, wind power generation and energy storage, smart grid, and national defense. At present, lead-acid batteries are still the largest and most widely used batteries in the world.

Second, the road to scientific and technological innovation
1. Innovation of materials and structures
 ii.Material innovation: In recent years, lead-acid batteries have made significant progress in terms of materials. For example, lead-carbon batteries improve the utilization of lead active substances and inhibit the growth of lead sulfate crystals by incorporating high-specific surface carbon materials into lead negative electrodes. This innovation makes the lead-carbon battery have both capacitive and battery characteristics, becoming a dual-function energy storage battery.
 ii.Structural innovation: Lead-acid batteries have also been innovated many times in structure, such as the use of three-dimensional and double-three-dimensional structure electrodes, fully sealed, tubular, horizontal and other new structures, which help to improve the performance and life of the battery.
2. Improvement of manufacturing process
 i.One-step positive electrode formula composite technology: the traditional lead-acid battery positive electrode lead paste production process is long, high energy consumption, pollution. The new "one-step positive electrode formulation composite technology" simplifies the production process, reduces energy consumption and pollution, and improves production efficiency.
 ii.Automated production lines: Some leading enterprises such as Tianneng have established automated production lines.These technologies not only improve production efficiency, but also significantly improve battery performance and consistency.

Third, future Outlook
With the continuous progress of science and technology and the increasingly strict environmental protection policies, the lead-acid battery industry will face more opportunities and challenges. On the one hand, the continuous emergence of new materials, new technologies and new processes will promote the further improvement of lead-acid battery performance; On the other hand, the trend of intelligence and digitalization will also accelerate the transformation and upgrading of the lead-acid battery industry. At the same time, with the continuous development of the recycled lead industry, the recycling of lead resources will become more efficient and sustainable.

In short, from lead sheets to smart batteries, the road to scientific and technological innovation of lead-acid batteries is a road full of hope and challenges. In the future development, lead-acid batteries will continue to play their unique advantages and roles to provide more reliable, efficient and environmentally friendly energy solutions for all walks of life.
