Abstract: In one aspect, a lithium battery with fast charging capability for an autonomous floor-cleaning apparatus may include a main body, a battery module, a first heat conducting unit, a second heat conducting unit, a first fan unit and a second fan unit. The main body may include a top board, a bottom board, a front side board, a rear side board, a left-side board and a right-side board. When the main body is assembled, it is further sealed by a predetermined type of glue so a receiving space is formed inside the main body, and the main body has a couple air inlets and an air outlet. In one embodiment, the first air inlet is disposed at a lower portion of the left-side board and the second air inlet is disposed at a lower portion of the right-side board; and the air outlet is disposed on the top board.
