Embodiment
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, the nonactivated detection method of a kind of dry state zinc-silver oxide cell, comprises the steps:
Step 101, choose the LCR tester 2 that model is ZM2353; Described LCR tester 2 is adjusted to ESR (Ω) shelves, output frequency is adjusted to 100kHz, Voltage Cortrol to 1V;
Step 102, by monomer series-connected for N number of dry state zinc-silver oxide cell rear composition dry state zinc-silver oxide cell group 1, and draw positive terminal and the negative terminal of dry state zinc-silver oxide cell group 1;
Step 103, above-mentioned positive terminal and negative terminal to be electrically connected with two root table pens of LCR tester 2 respectively; Annexation as shown in Figure 1;
Step 104, unlatching LCR tester 2, obtain AC impedance and the discharge capacity value of dry state zinc-silver oxide cell group 1.
Principle of work of the present invention is:
According to capacitance principle, any two insulated from each other and all form a capacitor between the conductor (comprising wire) of being separated by very near.As shown in Figure 1, positive and negative pole plate is metallic conductor to the structural representation of dry state pole plate group, and barrier film is good insulating body, and therefore pole plate group has the characteristic of electric capacity.
According to the architectural characteristic of zinc-silver oxide cell dry state pole plate group, the AC impedance of dry state pole plate group includes Ohmage and electric capacity capacitive reactance two parts.The Ohmage of zinc-silver oxide cell dry state pole plate group can be ignored relative to electric capacity capacitive reactance.Therefore, according to the principle of electric capacity, zinc-silver oxide cell dry state pole plate group can be similar to regards plane-parallel capacitor as, and AC impedance is electric capacity capacitor value.The capacitor value of capacitor amasss with the right opposite at capacitor the two poles of the earth, insulating medium between two die openings and pole plate is relevant.Zinc-silver oxide cell is with longer storage duration, and positive/negative plate and barrier film composition all can change a lot, and therefore between pole plate, insulating medium there occurs change, and therefore capacitor value also can change thereupon, thus cause AC impedance to change.Therefore by ac impedance measurement, can qualitative reflection battery with longer storage duration, the situation of change of electrical property.
For checking the method validity, select certain zinc-silver oxide cell monomers some, store 2 years, 4 years, 6 years, 8 years and 10 years respectively and carry out AC impedance test and the test of monomer discharge capacity, test result as shown in Figure 2.As can be seen from the figure, this zinc-silver oxide cell monomer discharge capacity constantly reduce with period of storage and AC impedance then constantly increase, thus zinc-silver oxide cell monomer electrical property situation can be inferred by ac impedance measurement value.
Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
