How to repair a part like this

Hi guys! I was trying to bend this part slightly so that the battery would sit flat, but it ended up being brittle and broke at the head. It is the arm that goes below the battery, and connects it to the circuits. How would I go about fixing/replacing it? It initially sat at 2 right angles. Would I need to solder, or is it too small for that? If I were to replace the part, how would I find it? Thanks!
