Embodiment 1

[0068] Production of battery A and battery B:

[0069] When hydrogen is charged in the negative electrode 53 of the battery, 2M+H 2 = 2MH;

[0070] When adding an oxidant to the positive electrode 55 of the battery, 2Ni(OH) 2 +H 2 o 2 =2NiOOH+2H 2 O;

[0071] The response to external discharge is:

[0072] Battery negative 53, MH+OH － =H 2 O+M+e;

[0073] Battery positive electrode 55, NiOOH+H 2 O=Ni(OH) 2 +OH — e.

[0074] During the charging and discharging process of the battery, the hydroxide ions in the alkaline electrolyte always maintain the original amount. The essence is that the added hydrogen reacts with the added oxidant to produce water.

[0075] When the battery is made, the negative electrode 53 of the battery adopts AB 5 Type hydrogen storage alloy as the active material, fill 12 grams of hydrogen storage alloy powder (D50 = 49 microns) into the copper grid, and compact it with a pressure of 20Mpa to make a negative electrode sheet with a size of ...

Embodiment 2

[0083] Production of battery A and battery B:

[0084] The negative electrode 53 of the battery uses carbon nanometers as the active material, fills 12 grams of carbon nanometers into the copper mesh, and compacts it with a pressure of 20 MPa to make a negative electrode sheet with a size of 50mm*200mm*0.55mm.

[0085] Battery positive electrode 55 uses 10 grams of spherical nickel hydroxide as the active material, adds 5% cobaltous oxide as the conductive agent, fills it into foamed nickel, and compacts it with a pressure of 20Mpa to make a positive electrode sheet with a size of 50mm* 200mm*0.6mm.

[0086] The separator 54 between the battery positive electrode 55 and the battery negative electrode 53 is made of PP material, and the cutting size of the separator 54 is 52mm*205mm. The soaking membrane 56 is made of PP material, and the cutting size is 52mm*205mm.

[0087] Battery Assembly:

[0088] The above materials are stacked into the battery casing 51 in the order of ...

Embodiment 5

[0092] Production of battery A and battery B:

[0093] The battery negative electrode 53 uses La-Y-Ni type hydrogen storage alloy as the active material, fills 12 grams of hydrogen storage alloy powder (D50=49 microns) into the copper mesh, and compacts it with a pressure of 20Mpa to make a negative electrode sheet , the size is 50mm*200mm*0.55mm.

[0094] Battery positive electrode 55 uses 10 grams of spherical nickel hydroxide as the active material, adds 5% cobaltous oxide as the conductive agent, fills it into foamed nickel, and compacts it with a pressure of 20Mpa to make a positive electrode sheet with a size of 50mm* 200mm*0.6mm.

[0095] The separator 54 between the battery positive electrode 55 and the battery negative electrode 53 is made of PP material, and the cutting size is 52mm*205mm. The soaking membrane 56 is made of PP material, and the cutting size is 52mm*205mm.

Abstract

The invention relates to the technical field of batteries, and discloses a hydrogen power battery system which comprises a battery body, a hydrogen storage tank, an oxidizing agent storage tank, an output conversion module and a control system, an output positive electrode and an output negative electrode are arranged on the output conversion module, and the battery body comprises a battery shell, a battery positive electrode and a battery negative electrode. The battery cathode comprises a cathode base band and a hydrogen storage material, the battery anode comprises an anode base band and a conducting strip, the battery shell is filled with alkaline electrolyte, the hydrogen storage tank is communicated with the battery cathode through a pipeline, and the oxidant storage tank is communicated with the battery anode through a pipeline. The hydrogen storage tank and the oxidant storage tank are controlled by the control system to convey hydrogen and an oxidant into the battery body, so that the battery is in a charged state and can continuously supply power to the outside, the battery continuously supplies power by adopting a fuel adding mode, the charging time is saved, and meanwhile, precious metal does not need to serve as a catalyst on the battery; and the application cost of the battery on a new energy vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a hydrogen power battery system. Background technique [0002] With the popularization of the concept of environmental protection, people's demand for clean new energy is gradually increasing. The development of new energy vehicles to reduce carbon emissions is one of the important measures for environmental protection. Most of the existing new energy vehicles use lithium-ion batteries. Lithium-ion batteries have the advantages of high energy density and high power. However, lithium-ion batteries have the following problems when used in new energy vehicles: (1) The battery life of the vehicle is weak, It needs to be charged at any time; (2) The charging time is long, and it takes at least 3 hours to fully charge once; (3) The cruising range shrinks seriously in low-temperature environments. Based on the above points, the promotion and popularization of lithium-ion batteries wil...
