Batrị 7.2V 3000mAh dakọtara maka Euro Pro Shark XB1918, V1917, V1950, VX3

Ajụjụ: Gịnị bụ batrị NiMH?

A: The anode ihe nke nickel-metal hydride batrị bụ Ni (OH) 2 (a na-akpọ NiO electrode), na-arụ ọrụ ihe onwunwe nke na-adịghị mma electrode bụ metal hydride, makwaara dị ka hydrogen nchekwa alloy (na electrode na-akpọ hydrogen nchekwa electrode), na electrolyte bụ 6mol / L potassium hydroxide ngwọta. Usoro mode nke nọ n'ọrụ ihe na-etolite electrode mpempe akwụkwọ tumadi na-agụnye sintering ụdị, slurry ụdị, nickel ụfụfụ ụdị, eriri nickel ụdị na agbakwunyere ụdị, wdg, na electrodes kwadebere site dị iche iche Filiks nwere oké ọdịiche na ikike na elu-ugbu a ihapu arụmọrụ, na batrị na-n'ozuzu na-emepụta dị ka usoro dị iche iche n'okpuru ọnọdụ dị iche iche. Ọtụtụ n'ime batrị obodo dị ka nkwukọrịta na-eji ụdị anode slurry na ụdị foam nickel cathode na-emepụta batrị. Mmeghachi omume kemịkalụ nke ụgwọ na mwepu bụ nke a:

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

Eletrọd na-adịghị mma: M+H2O+e-=MHab+OH-

Ngụkọta mmeghachi omume: Ni(OH)2+M=NiOOH+MH

Mara: M: Mmiri mmiri; Hab: adsorption nke hydrogen; Usoro aka ekpe gaa n'aka nri nke usoro mmeghachi omume bụ usoro ịchaji; Usoro aka nri gaa n'aka ekpe nke mmeghachi omume bụ usoro nkwụsị.

N'oge ịchaji, Ni (OH) 2 na OH- nke cathode na-emeghachi omume iji mepụta NiOOH na H2O, na e- wepụtara n'otu oge iji mepụta MH na OH-, na ngụkọta mmeghachi omume bụ Ni (OH) 2 na M iji mepụta NiOOH, na hydrogen nchekwa alloy na-echekwa hydrogen. N'adịghị ka mwepụta ahụ, MH ab na-ewepụta H+, H+ na OH- iji mepụta H2O na e-, na NiOOH, H2O na e-regenerate Ni(OH)2 na OH-. Ọkọlọtọ electromotive ike nke batrị bụ 1.319V.
