Why Lithium Batteries Are Replacing Lead-Acid Batteries
Jan 16, 2026
Lithium batteries are gradually replacing lead-acid batteries in the electric vehicle sector, but this process is not absolute. It is influenced by technological advancements, policy orientations, and market factors. The following analysis examines the current trend from multiple perspectives.
Performance advantages and market growth: Lithium batteries significantly outperform lead-acid batteries in terms of energy density, weight, and charging speed. For instance, their energy density can be 3-4 times that of lead-acid batteries, providing longer driving range in the same volume, and they support fast charging, recovering 80% of the battery's capacity in just 30 minutes. Additionally, enterprises like BYD Lithium Batteries have launched electric vehicle-grade lithium batteries, wh...
