Nīnau: He aha ka NiMH pila?

A: ʻO ka mea anode o ka nickel-metal hydride battery ʻo Ni (OH) 2 (i kapa ʻia ʻo NiO electrode), ʻo ka mea hana o ka electrode maikaʻi ʻole he hydride metala, ʻike ʻia hoʻi ʻo hydrogen storage alloy (ua kapa ʻia ka electrode hydrogen storage electrode), a ʻo ka electrolyte he 6mol/L potassium hydroxide solution. ʻO ke ʻano kaʻina hana o ka mea ikaika e hana i ka ʻāpana electrode electrode ka nui o ka sintering type, slurry type, nickel foam type, fiber nickel type and embedded type, etc. ʻO ka hapa nui o nā pila kīwila e like me ke kamaʻilio e hoʻohana ana i ka anode ʻano slurry a me ka cathode ʻano nickel foam e hana i nā pihi. ʻO ka hopena kemika o ka uku a me ka hoʻokuʻu ʻana penei:

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

ʻO ka electrode ʻino: M+H2O+e-=MHab+OH-

huina pau: Ni(OH)2+M=NiOOH+MH

Nānā: M: Hydrogen alloy; Hab: adsorption o ka hydrogen; ʻO ke kaʻina hana hema a ʻākau o ke ʻano reactive ke kaʻina hoʻouka; ʻO ke kaʻina hana ʻākau-a-hema o ka hopena ʻo ke kaʻina hoʻokuʻu.

I ka wā o ka hoʻouka ʻana, hana ka Ni(OH)2 a me OH- o ka cathode e hana i ka NiOOH a me H2O, a hoʻokuʻu ʻia ka e- i ka manawa like e hoʻohua ai i ka MH a me OH-, a ʻo ka hopena holoʻokoʻa ʻo Ni(OH)2 a me M e hana ai i ka NiOOH, a ʻo ka hale waihona hydrogen e mālama i ka hydrogen. I ka hoʻokaʻawale ʻana i ka hoʻokuʻu ʻana, hoʻokuʻu ʻo MH ab iā H+, H+ a me OH- e hoʻohua i ka H2O a me ka e-, a me NiOOH, H2O a me e- hoʻoulu hou iā Ni(OH)2 a me OH-. ʻO ka ikaika electromotive maʻamau o ka pākaukau ʻo 1.319V.
