1. Basic Principles:
Lithium-substituted lead-acid batteries operate through lithium-ion insertion/extraction between electrodes.
During charging, lithium ions release from the positive electrode and embed into the negative electrode via electrolyte; during discharging, ions return to the positive electrode while electrons flow externally to power devices. Unlike traditional lead-acid batteries' lead-sulfuric acid chemical reactions, this mechanism enables higher energy conversion efficiency.
2. Performance Characteristics:
High Energy Density:Lithium-ion variants (100-265Wh/kg) significantly exceed lead-acid batteries (30-50Wh/kg), enabling greater energy storage in compact/lightweight designs ideal for mobile power/distributed energy storage.
High Efficiency:Charge/discharge efficiency exceeds 90% (vs. lead-acid's 70-80%), minimizing energy loss and enhancing system economy. Long Cycle Life:Achieves 1000-2000+ cycles (vs. lead-acid's 300-500), reducing replacement frequency/costs for long-term applications like backup power systems.
3. Specifications: 12V60AH, 12V80AH, 12V100AH, 12V120AH, 12V150AH, 12V200AH, 12V250AH.
