Lead-to-lithium Storage Battery: The Mainstream Choice for Future Energy Storage

## Lead-to-lithium storage battery: the mainstream choice for future energy storage

Driven by the global energy structure transformation and carbon neutrality goals, energy storage technology is undergoing revolutionary changes. With its significant technical advantages and market performance, lead-to-lithium storage batteries are establishing their position as the mainstream choice for future energy storage.

The technical advantages of lead-to-lithium storage batteries are reflected in multiple dimensions. Its energy density reaches 200-300Wh/kg, which is 4-6 times that of traditional lead-acid batteries, greatly improving the energy storage capacity of energy storage systems. In a wide temperature range of -30℃ to 60℃, lithium batteries can still maintain a discharge efficiency of more than 90%, adapting to various complex environments. In addition, the cycle life of lithium batteries can reach more than 5,000 times, which is 10 times that of lead-acid batteries, significantly reducing the full life cycle cost.

Market data confirms the rapid development of lead-to-lithium storage batteries. In 2022, the global installed capacity of lithium battery energy storage will reach 50GWh, an increase of more than 80% year-on-year. In the field of communication base stations, the penetration rate of lithium batteries has exceeded 60%; in the data center backup power market, the share of lithium batteries has reached 45%. It is estimated that by 2025, the global lithium battery energy storage market will exceed US$100 billion.

Technological progress continues to promote the performance improvement and cost reduction of lead-to-lithium storage batteries. The thermal stability of new lithium iron phosphate batteries has been significantly improved, and safety has reached a new height; breakthroughs in solid-state battery technology have made it possible for energy density to exceed 500Wh/kg. At the same time, large-scale production has reduced the cost of lithium batteries at a rate of 15-20% per year, and it is expected that the cost per kilowatt-hour of lithium battery energy storage systems will drop to less than 0.3 yuan in 2025.

Lead-to-lithium storage batteries are reshaping the global energy storage landscape. Its technical advantages, market performance and cost reduction trend make it the mainstream choice for future energy storage. With technological progress and the expansion of application scenarios, lead-to-lithium storage batteries will play a key role in achieving carbon neutrality goals and building a new energy system.
