Rechargeable battery and manufacturing method threrof

A method of manufacturing a rechargeable battery, the method comprising:

• manufacturing a plurality of functional particles, each including a first aggregate having a positive active material, a second aggregate having a negative active material, and a separating aggregate that separates the first aggregate and the second aggregate and surrounds the first aggregate and the second aggregate;
• manufacturing a positive substrate having a plurality of first protrusions and a negative substrate having a plurality of second protrusions;
• providing the plurality of functional particles on one substrate of the positive substrate and the negative substrate and aligning the plurality of functional particles to place the first aggregate and the second aggregate at designated positions;
• and
• arranging the other substrate of the positive substrate and the negative substrate on the plurality of functional particles.

A functional particle manufacturing apparatus, comprising:

• a first pipe unit having a first branch pipe and a second branch pipe and one discharge pipe;
• the first branch pipe and the second branch pipe being connected to the discharge pipe;
• a second pipe unit surrounding the discharge pipe and having a length greater than the discharge pipe;
• a polymer solution supply unit configured to supply polymer solution to the first branch pipe and the second branch pipe;
• a positive slurry supply unit configured to intermittently discharge positive slurry into the polymer solution of the first branch pipe;
• a negative slurry supply unit configured to intermittently discharge negative slurry into the polymer solution of the second branch pipe;
• and
• an external fluid supply unit configured to supply an external fluid containing a coagulant to the second pipe unit.
