7.2V 3000mAh Batteri Ihuza na Euro Pro Shark XB1918, V1917, V1950, VX3

Ikibazo: Bateri ya NiMH ni iki?

Igisubizo: Ibikoresho bya anode ya batiri ya hydride ya nikel ni Ni (OH) 2 (bita NiO electrode), ibikoresho bikora bya electrode mbi ni hydride yicyuma, bizwi kandi ko bita hydrogène ububiko bwa electrode (electrode yitwa hydrogène ububiko bwa electrode), naho electrolyte ni 6mol / L potassium hydroxide. Uburyo bwimikorere yibikoresho bikora kugirango bigizwe na electrode electrode igizwe ahanini nubwoko bwo gucumura, ubwoko bwa slurry, ubwoko bwa nikel ifuro, ubwoko bwa fibre nikel nubwoko bwashyizwemo, nibindi, nibindi, kandi electrode yateguwe nuburyo butandukanye ifite itandukaniro rinini mubushobozi no mumikorere yo gusohora cyane, kandi bateri muri rusange zikorwa ukurikije inzira zitandukanye mubihe bitandukanye. Byinshi muri bateri za gisivili nkitumanaho zikoresha ubwoko bwa anode hamwe na cathode ya nikel ya kopi kugirango ikore bateri. Imiti yimiti yishyurwa nogusohora nuburyo bukurikira:

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

Electrode mbi: M + H2O + e- = MHab + OH-

Igisubizo cyose: Ni (OH) 2 + M = NiOOH + MH

Icyitonderwa: M: Amavuta ya hydrogen; Hab: adsorption ya hydrogen; Ibumoso-iburyo iburyo bwa formulaire reaction nuburyo bwo kwishyuza; Iburyo-ibumoso inzira ya reaction ni inzira yo gusohora.

Mugihe cyo kwishyuza, Ni (OH) 2 na OH- ya cathode yitwara kugirango ibe NiOOH na H2O, kandi e- irekurwa icyarimwe kugirango itange MH na OH-, kandi ibisubizo byose ni Ni (OH) 2 na M kugirango bibe NiOOH, kandi hydrogène ibika hydrogene ibika hydrogene. Bitandukanye no gusohora, MH ab irekura H +, H + na OH- kubyara H2O na e-, na NiOOH, H2O na e- kuvugurura Ni (OH) 2 na OH-. Imbaraga zisanzwe za electronique ya bateri ni 1.319V.
