The invention discloses a system for recycling batteries. The system comprises a combustion chamber of a rotary kiln, a secondary combustion chamber and flue gas purification equipment; the combustion chamber of the rotary kiln comprises a first combustion area and a second combustion area; the secondary combustion chamber is communicated with the combustion chamber of the rotary kiln; the flue gas purification equipment is communicated with the secondary combustion chamber. By the aid of the system for recycling the batteries, the batteries are combusted in the first combustion area at the temperature ranging from 100 DEG C to 150 DEG C for 30 to 60 minutes, so that sealing rings of the batteries are sufficiently damaged by means of pyrolysis, hydrogen and organic solvents in the batteries are released and are discharged by negative-pressure devices, and the batteries can be effectively prevented from being exploded at a high temperature; then the batteries are combusted in the secondary combustion area at the temperature ranging from 300 DEG C to 500 DEG C, first flue gas generated when the batteries are combusted is completely combusted in the secondary combustion chamber at the temperature ranging from 1200 DEG C to 1350 DEG C to form second flue gas, the second flue gas is purified by the flue gas purification equipment to form purified gas, and the purified gas is exhausted into the atmosphere. The system for recycling the batteries has the advantages that the batteries are prevented from being exploded, and the system is safe in operation. The invention further provides a method for recycling the batteries.
