For reaching above-mentioned purpose, a kind of Li-Ion rechargeable battery of the utility model is made up of a housing, a positive electrode cap, a negative pole cap, a circuit unit and a storage battery, wherein:
One housing is a hollow cylindrical, and the size that it meets general electric standard pond comprises that the upper and lower edge of housing extends a upper baffle ring and lower baffle ring to the cylinder inboard with vertical relatively encirclement situation respectively, and the last circular hole and the following circular hole of the formation of upper and lower baffle ring;
One positive electrode cap is installed on the hollow cylinder top of housing, comprises a cathode contact protruding upward;
One negative pole cap is installed on the hollow cylinder bottom of housing, comprises a cathode contact that protrudes to the bottom;
One circuit unit comprises a charging circuit, a voltage stabilizing circuit and a protective circuit, and
It is one cylindric that one lithium ion battery is, and is located at enclosure, and its positive pole is with respect to the positive electrode cap position, and negative pole is closely from the circuit unit position.
The described circuit unit that is installed on the housing hollow cylinder is in parallel with storage battery and be connected positive electrode cap and negative pole cap respectively.
The charging circuit of described circuit unit is in parallel with voltage stabilizing circuit; the common utmost point of its charging circuit and voltage stabilizing circuit is connected positive electrode cap; the utmost point that another is common and the positive pole of protective circuit and storage battery are connected in parallel, and the negative pole of voltage stabilizing circuit, protective circuit and storage battery all is connected to form the loop with the negative pole cap.
When described positive electrode cap was installed on the housing top, the last circular hole that its cathode contact sees through upper baffle ring outwards protruded;
Described negative pole cap device is when the hollow cylinder bottom of housing, and the cathode contact of this negative pole cap sees through that circular hole outwards protrudes under the lower baffle ring;
The protrusion area of described cathode contact is greater than the protrusion area of cathode contact;
From the above, the utility model directly is provided with charging circuit, voltage stabilizing circuit and protective circuit on rechargeable battery, and the useful life and voltage regulation result, the while that have further promoted battery have by this also reduced the charging interval.
