Ni-MH Cell Performance Positive electrode: Ni(OH)2+OH-=NiOOH+H2O+e- Negative electrode: M+H2O+e-=MHab+OH- Total reaction: Ni(OH)2+M=NiOOH+MH Note: M: hydrogen alloy; Hab: adsorbed hydrogen; the process from left to right of the reaction formula is a charging process; the process from right to left of the reaction formula is a discharge process. When charging, the positive electrode's Ni(OH)2 reacts with OH- to generate NiOOH and H2O, and at the same time releases e- to generate MH and OH- together. The total reaction is Ni(OH)2 and M to generate NiOOH, and the hydrogen storage alloy stores hydrogen; In contrast, MHab releases H+, H+ and OH- generate H2O and e-, and NiOOH, H2O and e- regenerate Ni(OH)2 and OH-. The standard electromotive force of the battery is 1.319V. Our company also has  Ni-MH Cell Performance  on sale, welcome to contact us.

  As a   Ni-MH Battery Pack Supplier , share it with you. The positive electrode active material of the nickel-hydrogen battery is Ni(OH)2 (called NiO electrode), the negative electrode active material is metal hydride, also called hydrogen storage alloy (the electrode is called hydrogen storage electrode), and the electrolyte is 6mol/L potassium hydroxide solution. The process methods for the active material to form the electrode pads mainly include sintering, slurrying, foaming nickel, fiber nickel and infiltrating, etc. Electrodes prepared by different processes have large differences in capacity and large current discharge performance. The battery is produced in different processes according to the conditions of use. Most of the civilian batteries for communications, etc., use drawn-out type negative electrodes and foamed nickel type positive electrodes to form batteries. The charge and discharge chemical reaction are as follows: Ni-MH Cell Performance Positive electrode: ...

Several key factors affect the cycle characteristics of   Solar Lighting Battery Lithium : First, the environmental humidity. Too much water can cause adverse reactions of positive and negative active substances, destroy their structure, and harm the circulatory system. In addition, too much water is not good for the production of SEI film, but despite the trace elements of water It is difficult to remove, but trace element water can ensure the characteristics of lithium batteries to a certain level. Solar Lighting Battery Lithium Second, positive and negative stage compaction. The positive and negative density is too high, although it can increase the specific energy of the lithium battery cell, it will also reduce the cyclic system characteristics of the raw material to a certain level. The analysis of the basic theory believes that the higher the density, the destruction of the raw material structure The larger, and the structure of the raw materials is also the basis to ensure ...
