Lead-acid battery vs lithium battery: Technological change in the energy storage market
In the field of energy storage technology, the competition between lead-acid batteries and lithium batteries is reshaping the market landscape. This technological change is not only about product performance, but will also determine the future development direction of energy storage.
As a representative of traditional energy storage technology, lead-acid batteries occupy an important position in the energy storage market with their cost advantages and mature technical system. With low material costs and a complete recycling system, they still have irreplaceable advantages in the fields of fixed energy storage and backup power supply. However, their inherent defects of low energy density and short cycle life are becoming increasingly prominent in new application scenarios.
The breakthrough development of lithium battery technology is changing this situation. Its energy density is 3-4 times that of lead-acid batteries, its cycle life is extended by more than 5 times, and its charging and discharging efficiency is increased to more than 95%. These technical advantages have enabled lithium batteries to expand rapidly in emerging fields such as electric vehicles and distributed energy storage. Despite the high initial cost, the full life cycle cost has shown obvious advantages.
According to market data, the market share of lithium batteries is growing at a rate of more than 20% per year. In emerging markets such as user-side energy storage and 5G base station backup power, the penetration rate of lithium batteries has exceeded 60%. This trend indicates that energy storage technology is undergoing a critical transition from quantitative change to qualitative change.
In the future, the energy storage market will present a diversified development pattern. Lead-acid batteries will maintain their market position in specific areas, while lithium batteries will dominate the high-end application market. Technological innovation will continue to drive down energy storage costs and provide key support for energy transformation. This technological change will not only reshape the energy storage industry landscape, but will also profoundly affect the evolution path of the global energy system.
