The present disclosure relates to a lithium-ion storage battery. The lithium-ion storage battery has a capacity greater than or equal to 20 Ah and includes at least one battery unit. The battery unit includes a positive electrode and a negative electrode, a separator, an electrolyte solution, and an external encapsulating shell. The separator is sandwiched between the positive electrode and the negative electrode, and the electrolyte solution is filled between the positive electrode and the negative electrode. The positive electrode, the negative electrode, the separator, and the electrolyte solution are encapsulated in the external encapsulating shell. The positive electrode defines a number of first through-holes. The negative electrode defines a number of second through-holes. Each of the second through-holes corresponds to one first through-hole. |
