Technical Field
[0001] The utility model relates to the technical field of batteries, in particular to a nickel-hydrogen battery with a long cycle life. Background Art
[0002] Nickel-metal hydride battery is a secondary battery with nickel and hydrogen as main raw materials. It combines the chemical activity of nickel and the energy storage characteristics of hydrogen, and has high energy density and environmental protection characteristics. Due to its excellent charging and discharging performance, nickel-metal hydride battery is widely used in many fields, such as mobile power, electric vehicles, household appliances, etc. When we compare nickel-metal hydride battery with other types of batteries, we can see its unique advantages in environmental protection, energy density and life. However, higher production cost and self-discharge rate are its main disadvantages. Compared with lithium-ion battery, nickel-metal hydride battery has lower energy density, but its safety performance is generally better and the cost is lower. When choosing a battery, you need to decide the most suitable battery type according to the specific application scenario and requirements.
[0003] After searching, the patent number "CN220544020U" mentioned in the text that "the utility model discloses a nickel-hydrogen battery with directional heat dissipation, including a directional heat conduction mechanism sleeved on the outside of the electrode core, the directional heat conduction mechanism includes a plurality of core-wrapped tubes, the core-wrapped tubes are connected to the cover plates at both ends of the battery through heat-conducting wires, and a pair of heat-conducting paddle mechanisms are arranged on the cover plates. An annular cavity is arranged in the core-wrapped tube, and the annular cavity is filled with a heat-conducting solvent. One side of the arc-shaped protrusion of the core-wrapped tube is made of heat-insulating material. The heat-conducting paddle mechanism includes a pair of heat-conducting paddles, and a gasket for clamping a heat-conducting rod is arranged at the end of the heat-conducting paddle, and the heat-conducting rod is arranged on the battery pack frame." When in use, the utility model uses a shell with a directional heat conduction structure to wrap the electrode core, and transmits heat mainly from the upper and lower cover plates through the heat conducting wire, wherein the heat of the upper end cover is transmitted to the heat conducting rod on the battery pack mounting frame through the heat conducting paddle mechanism to achieve directional heat dissipation, and at the same time, the heat conducting paddle mechanism secures the installation of the battery by clamping the heat conducting rod. However, during the use of the nickel-hydrogen battery, due to the discharge property of the battery itself, when it is idle for a long time, the electrode liquid in the battery will remain static for a long time, and the long-term static state is likely to cause electrode loss inside the battery, thereby reducing the service life of the nickel-hydrogen battery, which is not conducive to long-term use.

The nickel-metal hydride battery protection component 21 is disposed on the inner side of the battery compartment 1 , and the overcurrent protection component 22 is disposed on the front side of the battery compartment 1 .
[0025] Furthermore, the nickel-hydrogen battery protection component 21 includes a nickel-hydrogen battery pack 211, a hydrogen storage alloy electrode 212, a fluoroplastic film 213 and a battery top cover 214. The inner side of the battery compartment 1 is connected to the nickel-hydrogen battery pack 211 by a slot, the top of the nickel-hydrogen battery pack 211 is welded with a hydrogen storage alloy electrode 212, the inner wall of the battery compartment 1 is provided with a fluoroplastic film 213, and the top of the battery compartment 1 is provided with a battery top cover 214. When needed, more electricity can be stored through the two groups of nickel-hydrogen battery packs 211, and during use, since the two groups of nickel-hydrogen battery packs 211 are independently connected to the voltage transformer 221, when one of the nickel-hydrogen battery packs 211 fails, the other group of nickel-hydrogen battery packs 211 can continue to work, thereby extending the working time and service life.
[0026] Furthermore, the hydrogen storage alloy electrode 212 is welded to the nickel-hydrogen battery pack 211. The hydrogen storage alloy electrode 212 is made of hydrogen storage alloy. When needed, the hydrogen storage alloy electrode 212 uses hydrogen storage alloy, and hydrogen storage alloy can absorb a large amount of hydrogen, which makes them ideal electrode materials, reduces voltage loss, and prolongs service life.
[0027] Furthermore, the fluoroplastic film 213 and the battery compartment 1 are adhesively connected, and the fluoroplastic film 213 fits tightly to the battery compartment 1. When needed, the fluoroplastic film 213 can protect the nickel-metal hydride battery pack 211 to prevent moisture from entering the battery compartment 1.

[0028] Furthermore, the overcurrent protection component 22 includes a voltage transformer 221, a voltage touch screen 222, a power consumption lamp 223 and a power connection port 224. The voltage transformer 221 is installed on the front side of the battery compartment 1, and the voltage touch screen 222 is installed on the front side of the voltage transformer 221.

When left idle for a long time, the power-consuming lamp stand 223 will automatically light up after a certain period of time, thereby consuming the power in the nickel-metal hydride battery pack 211, so that the electrode liquid in the nickel-metal hydride battery pack 211 is always kept in a moving state, thereby extending the service life of the nickel-metal hydride battery pack 211.
[0031] Working principle: A nickel-hydrogen battery with a long cycle life is moved to the working position.

After the connection is completed, the battery top cover 214 is covered on the upper side of the battery compartment 1. The second step is to connect the external equipment that needs to use electricity to the power connection port 224 using an external wire according to the needs of the user, and then adjust the voltage required by the voltage transformer 221 through the voltage touch screen 222 according to the required voltage and other requirements. During a long period of idleness, the power-consuming lamp 223 will light up regularly to consume the power of the nickel-hydrogen battery pack 211 to achieve the purpose of circulating electricity. In this way, the use process of a nickel-hydrogen battery with a long cycle life is completed.
