The invention relates to the technical field of a lithium battery, in particular to a packaging structure of the hardware of the battery. The problem of instable installation of the hardware of the conventional lithium battery is solved. The adopted technical scheme is that: the package structure comprises a battery cell, a rubber shell, a positive nickel piece, a negative nickel piece and an identification material layer. The package structure is characterized by also comprising a pulse code modulation (PCM) plate which is provided with chip hardware, wherein the positive nickel piece and the negative nickel piece are connected with a piece of chip hardware respectively; and a PCM slot which is matched with the PCM plate and a hardware positioning hole which is matched with the chip hardware are formed at edges of the rubber shell. The packaging structure has the advantages that: a packaging process is simple; the PCM plate of the chip hardware and the rubber shell are assembled simply; repair is convenient; the structure is firm; packaging cost is low; the chip hardware replaces a hardware bracket structure, so the cost of a mould is low; the process is simple and convenient; and production efficiency is high.
