Comparison of 48V Lithium-Ion and Lead-Acid Batteries
weight energy density
At present, the energy density of lithium batteries is generally 200~260wh / g, lead-acid is generally 50~70wh / g. The weight energy density of lithium batteries is 3~5 times that of lead-acid, which means that the capacity of lithium batteries is three to five times stronger than that of lead-acid batteries under the same weight, so lithium batteries have an absolute advantage in energy storage.
Volumetric Energy Density
Since the volumetric energy density of lithium batteries is usually about 1.5 times that of lead-acid batteries, lithium batteries are about 30% smaller than lead-acid batteries under the same capacity.
Service life
The most popular lithium battery materials are lithium ternary and lithium iron. For example, Li-ion ternary batteries usually have 1000 cycles, Li-FePO4 batteries have over 2000 cycles, and lead-acid batteries usually have 300-350 cycles. Then it means that lithium batteries last about 3-6 times longer than lead-acid batteries.
price cost
Lead-acid batteries are currently cheaper than lithium batteries, which are about three times as expensive. However, by analyzing the lifespan, lithium batteries have a longer lifespan if the same cost is used.
Environmental Protection
Lead-acid batteries are highly polluting, while lithium batteries are relatively greener in terms of production and recycling.
