1. A flexible battery, comprising: a plurality of flexible electric core blocks; wherein
the plurality of flexible electric core blocks are arranged at intervals along a curling traveling direction, and a spacing between adjacent flexible electric core blocks is gradually increased along the curling traveling direction;
at least one flexible connecting bridge is arranged between the adjacent flexible electric core blocks, and two ends of the flexible connecting bridge are electrically connected with the adjacent flexible electric core blocks respectively;
wherein the curling traveling direction is the same as an arrangement direction of the plurality of flexible electric core blocks;
wherein the plurality of flexible electric core blocks are arranged on a same reference plane, and a projection area of the outermost flexible electric core block among the plurality of flexible electric core blocks onto the reference plane is larger than a projection area of each of the flexible electric core blocks except the outermost flexible electric core block onto the reference plane;
