The energy density by weight is different, the energy density by volume is different, and the lifespan is different.
1. Different weight energy densities: The energy density of lithium batteries is generally between 200 and 260 Whg, and that of storage batteries is generally between 50 and 70 Whg, which means that with the same capacity, the storage battery is 3-5 times higher than lithium battery.
2. Different volumetric energy density: The volumetric capacity density of lithium batteries is generally about 1.5 times that of storage batteries. Therefore, with the same capacity, lithium batteries are 30% smaller than storage batteries.
3. Lifespan: The cycle number of lithium batteries is more than 1,000 times, while the cycle number of storage batteries is only 300-350 times. Battery lifelithium is greater than 3. times that of storage batteries.
