NOVELTY - The purpose of the utility model is to provide a graphene lead-acid battery for electric bicycle, improved by improvement of strength of the battery case graphene composite electrode, which solves the problem caused by collision with graphene composite electrode of the lead-acid battery is difficult to be applied to the electric bicycle. In order to realize said purpose, this utility model, comprising a storage battery shell, the battery shell by a partition board is divided into multiple battery slots, each said battery groove is equipped with a lead-acid storage battery polar group, wherein the negative plate of lead acid storage battery electrode group is made of graphene, the lead acid storage battery electrode group is the positive and negative plate is slantwise set, lead-acid storage battery polar group and is provided with a compression plate. By this setting, the utility model adopts the inclined set in the pole group set solution and compared to additionally set the compression plate and the flexible block and existing technology. can be avoided in the process of daily using the graphene electrode board is damaged caused by collision;
