The rise of electric vehicles has brought renewed attention to lead-acid batteries, which have excellent energy density and cycle life at a lower cost. Lead-acid batteries are currently one of the most dominant EV battery types.
Lead-acid batteries have excellent energy density, and the energy stored per unit volume can reach 200-300Wh/kg, which is much higher than other major electric vehicle battery types. In this way, if the power source of the entire electric vehicle is changed from a traditional engine to a lead-acid battery, not only can the overall weight be reduced, but the cruising range can also be significantly increased.
Most of the lead-acid batteries currently used in the market are closed cycles, and the cycle life can reach 2000-3000 cycles under normal conditions. For some specific applications (such as aerospace and military industries), this life is quite enough.
Most of the lead-acid batteries currently used in the market are semiconductor-type products, and the cost is generally around 1-2 yuan/W. With the continuous improvement of industrial production and the decline of material costs, the cost advantage will gradually emerge.
