A battery and what are the differences and similarities of secondary battery

Only discharge once a battery, secondary battery can be used repeatedly charging and discharging cycle, rechargeable battery during discharge electrode size and reversible change between structure, so the design must adjust these changes, while a battery inside is much simpler, because it does not need to adjust the reversible change, a battery quality specific capacity and specific storage volume were greater than general rechargeable batteries, but the internal resistance is far larger than the secondary battery, so the load capacity is low, in addition, the battery self-discharge is far less than that of the secondary battery.
