Weight energy density

　　At present, the energy density of lithium battery is generally 200~260wh/g, and that of lead acid is generally 50~70wh/g. The weight energy density of lithium battery is 3~5 times that of lead acid, which means that the capacity of lithium battery is three to five times stronger than that of lead acid battery under the same weight. Therefore, lithium battery has absolute advantages in energy storage.

　　Volume energy density

　　Since the volume energy density of lithium battery is usually about 1.5 times that of lead-acid battery, under the same capacity, lithium battery is about 30% smaller than lead-acid battery.

　　service life

　　At present, the most popular lithium battery materials are lithium ternary and lithium iron. For example, ternary lithium batteries typically have 1000 cycles, lithium iron phosphate batteries have more than 2000 cycles, and lead-acid batteries typically have 300-350 cycles. That means the life of lithium battery is about 3-6 times as long as that of lead-acid battery.

　　Price cost

　　Lead acid batteries are currently cheaper than lithium batteries, which cost about three times as much. However, through the service life analysis, if the same cost is used, the life of lithium battery will be longer.

　　environmental protection

　　Lead acid batteries are seriously polluted, and lithium batteries are relatively green in production and recycling.
