The invention belongs to the technical field of current collectors, and particularly relates to a bimodal current collector of an alkaline environment-friendly zinc-manganese battery capable of preventing leakage and convenient to assemble. With regard to the problems of splicing inconvenience, liquid leakage risk and recycling difficulty, the following scheme is proposed and comprises a pin body,a positive electrode cap, a plastic sealing disc, wherein grooves are formed in a side wall of the pin body at equal distance, the cross sections of the grooves are of V-shaped structures, a thorn part is arranged at a top end of the needle body, a pin seat is in threaded connection with a bottom of the pin body, a sleeve is arranged at a middle position of an outer wall of a top end of the plastic sealing disc, two ends of an inner wall of the sleeve respectively sleeve a top end of the pin seat and the bottom of the pin body, a convex ring is arranged at the inner wall of the sleeve, and sealing rings are arranged at positions of a top end and a bottom end of the convex ring. By the bimodal current collector, splicing is convenient, meanwhile, the bimodal current collector is convenientto recycle, and the recycling difficulty of the current collector is reduced; and by the plastic sealing disc and the sleeve which are arranged in a matching way, the sealing performance is favorablyimproved, and the liquid leakage probability is reduced.
