1, Basic principles
Lithium substituted lead-acid batteries achieve the charging and discharging process through the insertion and extraction of lithium ions between the positive and negative electrodes. During charging, lithium ions are released from the positive electrode material and embedded into the negative electrode material through the electrolyte; When discharging, the opposite is true. Lithium ions return from the negative electrode to the positive electrode, and electrons flow in the external circuit to form a current, thereby supplying power to external devices. Unlike lead-acid batteries that undergo a chemical reaction between lead and sulfuric acid, this charging and discharging method endows lithium-ion lead-acid batteries with higher energy conversion efficiency.

2, Performance characteristics
High energy density
The energy density of lithium-ion lead-acid batteries is significantly improved compared to traditional lead-acid batteries. For example, the energy density of lithium-ion batteries is usually between 100-265Wh/kg, while the energy density of lead-acid batteries is generally between 30-50Wh/kg. This means that under the same weight, lithium-ion lead-acid batteries can store more electrical energy. For power supply applications, they can meet more electricity needs with smaller volume and weight, especially suitable for power supply scenarios that require space and weight, such as mobile power supply devices or distributed energy storage systems.
High charging and discharging efficiency
The charging and discharging efficiency of lithium-ion lead-acid batteries can reach over 90%, while the charging and discharging efficiency of lead-acid batteries is generally between 70% and 80%. High charging and discharging efficiency means that there is less energy loss during the charging process, and the equipment can be powered more effectively during discharge, reducing energy waste and improving the economy and practicality of the entire power supply system.
Long cycle life
High quality lithium-ion lead-acid batteries can easily achieve a cycle life of over 1000-2000 times, while lead-acid batteries typically have a cycle life of around 300-500 times. Long cycle life makes lithium lead-acid batteries more cost-effective during long-term use, reducing the hassle and cost of frequent battery replacement, and suitable for situations that require long-term stable power supply, such as backup power systems.
