7.2V 3000mAh Battery Yogwirizana ndi Euro Pro Shark XB1918, V1917, V1950, VX3

Q: Kodi betri ya NiMH ndi chiyani?

A: Zinthu za anode za batire ya nickel-metal hydride ndi Ni (OH) 2 (yotchedwa NiO electrode), chogwiritsira ntchito cha electrode negative ndi metal hydride, yomwe imadziwikanso kuti hydrogen storage alloy (electrode imatchedwa hydrogen storage electrode), ndi electrolyte ndi 6mol / L potassium hydroxide solution. The ndondomeko akafuna zinthu yogwira kupanga elekitirodi elekitirodi chidutswa makamaka zikuphatikizapo sintering mtundu, slurry mtundu, faifi tambala thovu mtundu, CHIKWANGWANI faifi tambala mtundu ndi ophatikizidwa mtundu, etc., ndi maelekitirodi okonzedwa ndi njira zosiyanasiyana ndi kusiyana kwakukulu mu mphamvu ndi mkulu-pano kumaliseche ntchito, ndi mabatire zambiri amapangidwa malinga ndi njira zosiyanasiyana pamikhalidwe yosiyanasiyana. Mabatire ambiri aboma monga kulumikizana amagwiritsa ntchito anode yamtundu wa slurry ndi foam nickel type cathode kupanga mabatire. Chemical reaction of charge and discharge ndi motere:

Cathode: Ni(OH)2+OH-=NiOOH+H2O+e-

Elekitirodi yolakwika: M+H2O+e-=MHab+OH-

Zotsatira zonse: Ni(OH)2+M=NiOOH+MH

Zindikirani: M: Aloyi ya haidrojeni; Hab: adsorption wa haidrojeni; Njira yopita kumanzere kupita kumanja ya fomula yokhazikika ndiyo kulipiritsa; Njira yochokera kumanja kupita kumanzere ndi njira yotulutsira.

Panthawi yolipiritsa, Ni (OH) 2 ndi OH- ya cathode imachita kupanga NiOOH ndi H2O, ndipo e- imatulutsidwa nthawi imodzi kuti ipange MH ndi OH-, ndipo zotsatira zake zonse ndi Ni (OH) 2 ndi M kupanga NiOOH, ndi hydrogen storage alloy store hydrogen. Mosiyana ndi kutulutsa, MH ab imatulutsa H +, H + ndi OH- kupanga H2O ndi e-, ndi NiOOH, H2O ndi e- regenerate Ni(OH)2 ndi OH-. Mphamvu yamagetsi yamagetsi ya batri ndi 1.319V.
