48V lithium-ion battery and lead-acid battery comparison
gravimetric energy density
At present, the energy density of lithium batteries is generally 200~260wh/g, lead-acid is generally 50~70wh/g, and the weight energy density of lithium batteries is 3~5 times that of lead-acid, which means that under the same weight, the capacity of lithium batteries is higher than that of lead-acid batteries. Acid batteries are three to five times stronger, so lithium batteries have an advantage in energy storage.
volume 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 at the same capacity
service life
At present, the most popular lithium battery materials are ternary lithium and iron lithium. Lianyungang low temperature ternary lithium battery, for example, ternary lithium battery usually has 1000 cycles, lithium iron phosphate battery has more than 2000 cycles, and lead-acid battery usually has 300-350 cycles. Then it means that the life of lithium battery is about 3-6 times that of lead-acid battery.
price cost
Lead-acid batteries are currently cheaper than lithium-ion batteries, which are about three times as expensive. However, through the service life analysis, if the same cost is used, the life of the lithium battery is longer.
environmental protection
Lead-acid batteries are seriously polluted, and lithium batteries are relatively greener in terms of production and recycling.
