Description
The utility model relates to a chargeable basicity zinc-manganese cell, especially a chargeable basicity zinc-manganese cell of series connection combination with partial pressure control function.
The chargeable alkaline zinc-manganese battery in the market has the advantages of high energy, low cost, good storage performance, no need of charging for the first use, small self-discharge and moderate charging and discharging service life, and is especially used as a power supply for military communicationCan be used as a primary battery, can be used as a rechargeable battery during normal training, and has lower price than a cadmium-nickel battery. However, the rechargeable alkaline zinc-manganese dioxide battery has poor overcharge resistance, the battery is required to be charged under the condition of constant voltage, the charging voltage of each single battery cannot be more than 1.80V, and when the charging voltage of the single battery is more than 1.80V, the reversibility of electrode reaction is lost due to the fact that manganese dioxide on the positive electrode of the battery is further oxidized into high-price soluble manganate, and the service life of the whole battery is ended. When the battery is used as a single battery, the overcharge can be effectively avoided due to the adoption of constant voltage charging, but when the battery is used as a series combined battery, the total constant voltage charging voltage is multiple times of the charging voltage of the single battery, but due to the slight difference of the performances of the single batteries, the charging voltage distribution of the single batteries is different during charging, the voltage of some single batteries is higher, the voltage of some single batteries is lower, the discreteness is further intensified along with the increase of the cycle times, once the voltage of a certain single battery exceeds 1.76V, hydrogen is generated at a negative electrode, zinc dendrite is generated along with the generation of the zinc dendrite, and if the voltage exceeds 1.80V, the positive electrode is further oxidized, the service life of the single battery is rapidly terminated, and the service life of the whole combined battery is attenuated. Because the problem of overcharge resistance cannot be solved, rechargeable alkaline zinc-manganese dioxide batteries are difficult to apply and popularize to combined batteries, and in order to improve the overcharge resistance, the overcharge resistance protection capability of positive electrode manganese dioxide needs to be improved. Previous work has focused on formulation modifications of the positive electrode manganese dioxideReport the addition of V to manganese dioxide for positive electrodes 2 O 5 、NiO、Co 2 O 3 And the like, which can reduce the overpotential of oxygen on the surface thereof, and desirably convert the overcharged electric energy into oxygen to prevent the positive electrode from further oxidation, thereby improving the overcharge capability. However, the problem of overcharge solved by this method is far from reaching practical level because it is difficult to ensure 100% conversion of overcharge electric energy into oxygen, and there is always some further oxidation of manganese dioxide, and in addition, the oxidation speed of the cathode absorbing the anode is slow, and the oxygen generated by the anode can not be absorbed by the cathode in time, and the battery can also swellAnd the problem of positive electrode oxidation caused by overcharge of the combined rechargeable alkaline zinc-manganese dioxide battery is solved.
The invention aims to solve the problem that the reversibility of the battery is lost due to electrode reaction caused by oxidation of the anode of partial single batteries due to uneven distribution of charging voltage of each single battery; thereby providing a combined rechargeable alkaline zinc-manganese battery with simple structure, convenient use and partial pressure control function.
The utility model discloses a realize like this: the device is formed by connecting rechargeable alkaline zinc-manganese batteries in series, and a shunt control circuit capable of being automatically switched on and off is connected between each rechargeable alkaline zinc-manganese battery in parallel and consists of two silicon diodes, a resistor and a synchronous switch. This circuit is in the off state when the battery is left open or discharged, and only works during constant voltage charging. The shunting capacity of each single battery shunting control circuit depends on the charging voltage of the single battery, if the charging voltage is high, the current flowing through the shunting control circuit is large, namely the charging current flowing through the single battery is small, so that the uniform distribution of the charging voltage of each single battery is effectively ensured, the overcharge is avoided, and the service life of the combined rechargeable alkaline zinc-manganese battery can be greatly prolonged.
The utility model discloses simple structure, with low costs, the shunt control electric current can be adorned inside the battery, also can adorn in the charger, both had been applicable to the cylindrical monomer series battery, also was applicable to square battery.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is a schematic circuit diagram of a 13.5 v combined rechargeable alkaline zn-mn battery according to an embodiment of the present invention.
Referring to fig. 1,W is a single battery, D is a silicon diode, R is a resistor, and J is a normally open contact independent of each other of the same relay, which functions as a synchronous switch. It can be seen from fig. 1 that J, two silicon diodes D and a resistor R form a shunt control circuit, the shunt control circuit is connected in parallel at two ends of each single battery W, J is a normally open contact of a relay, and when the battery is open or discharged, a coil of the relay is in an off state because the coil of the relay is not energized; when the battery is charged, the coil of the relay is simultaneously applied with voltage, only at this time, the shunt control circuit is conducted to work, the two silicon diodes D connected in series have forward conduction voltage of about 1.4 volts, when the charging voltage is less than the conduction voltage of 1.4 volts, the current flowing through the two silicon diodes D is very small, when the charging voltage is greater than the conduction voltage of 1.4 volts, the current flowing through the two silicon diodes D is remarkably increased, so that the current flowing through the shunt control circuit is very small when the charging voltage is less than 1.4 volts, when the charging voltage is greater than 1.4 volts, particularly 1.7 volts, the current flowing through the shunt control circuit is remarkably increased, the charging current flowing through the single battery W is relatively small, the resistor R has the function of adjusting the optimal shunt effect according to the capacity of the single battery W, namely, the single battery W is ensured not to be overcharged, and high charging efficiency is kept. The charging voltage division control process is completed as follows: the charger adopts a constant voltage 15.3V power supply (charger), the charger is attached with a power supply which can supply power for the relay, a combined rechargeable alkaline zinc-manganese battery to be charged is connected to the charger, the charger charges the battery and provides a working power supply for a relay coil, a normally open contact J of the relay is simultaneously attracted, the shunt control circuit works, when the charging voltage of a single battery W is lower than 1.4V, two silicon diodes D are in a micro-conduction state, the current flowing through the shunt control circuit is very small, and thus, the higher charging efficiency can be ensured. Along with the charging, the charging voltage of the battery is increased, when the charging voltage exceeds the forward conducting voltage of the two silicon diodes D by 1.4V, the two silicon diodes D are conducted, the current flowing through the shunt control circuit is obviously increased, the charging current flowing through the single battery W is greatly reduced, namely the higher the charging voltage of the single battery W is, the larger the shunt of the shunt control circuit is, the lower the charging current of the single battery W is; therefore, the charging voltage of each single battery W of the combined rechargeable alkaline zinc-manganese dioxide battery can be leveled, the charging voltage of each single battery W is ensured not to exceed 1.8V, and the overcharge of the single batteries W is avoided. Table 1 shows a voltage distribution comparison table for a combined rechargeable alkaline zn-mn battery without a partial pressure control function and a combined rechargeable alkaline zn-mn battery with a partial pressure control function.
Table 1:
| electricity without voltage division control function Circulation 5 of the cell (constant pressure) 15.3 volt charging) | |
1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
| Voltage (volt) | 1.85 | 1.61 | 1.90 | 1.84 | 1.53 | 1.46 | 1.75 | 1.73 | 1.63 | |
| With voltage-dividing control function Circulation of the pond for 20 th time (constant Voltage 15.3 volt charging) | |

| Voltage (volt) | 1.68 | 1.70 | 1.72 | 1.68 | 1.69 | 1.71 | 1.76 | 1.67 | 1.69 |
It can be seen from table 1 that after 20 times of cyclic discharge, the voltage of each single battery W is still distributed between 1.67 v and 1.76 v, and no single battery W exceeds 1.80 v; although the batteries without the partial pressure control function only pass 5 times of circulation, the voltage distribution of each single battery W is extremely uneven, the voltage of some single batteries W exceeds 1.80V, the single battery W with the overhigh charging voltage is quickly out of work, and the service life of the series combination rechargeable alkaline zinc-manganese battery is seriously influenced.
