Betri ea nickel-cadmium (betri ea NiCd kapa betri ea NiCad) ke mofuta oa betri e ka tjhajoang hape e sebelisang nickel oxide hydroxide le metallic cadmium joalo ka li-electrode.
Kgutsufatso ya Ni-Cd e nkiloe ho matshwao a dikhemikhale a nickel (Ni) le cadmium (Cd): khutsufatso ya NiCad ke letshwao la kgwebo le ngodisitsweng la SAFT Corporation, leha lebitso lena la letswai le sebediswa hangata ho hlalosa dibetri tsohle tsa Ni–Cd.
Libetri tsa nickel-cadmium tsa Wet-cell li qapiloe ka 1898. Har'a litheknoloji tsa betri tse khonang ho nchafatsoa, NiCd e ile ea lahleheloa ke karolo ea 'maraka ka potlako lilemong tsa bo-1990, ho ea ho libeteri tsa NiMH le Li-ion; karolo ea 'maraka e theohile ka 80%.
Betri ea Ni-Cd e na le motlakase oa ho qetela nakong ea ho tsoa hoo e ka bang 1.2 volts e fokotsehang hanyane ho fihlela qetellong ea ho tsoa. Libetri tsa Ni-Cd li entsoe ka mefuta e mengata ea boholo le bokhoni, ho tloha mefuteng e koetsoeng e tiisitsoeng e ka fapanyetsanoang le lisele tse omeletseng tsa carbon-zinc, ho ea ho lisele tse kholo tse nang le moea o motlakase tse sebelisetsoang matla a standby le matla a sepheo.
Ha ho bapisoa le mefuta e meng ea lisele tse nchafalitsoeng li fana ka bophelo bo botle ba potoloho le ts'ebetso ka mocheso o tlase o nang le matla a lekaneng empa molemo oa eona o moholo ke bokhoni ba ho fana ka hoo e batlang e le matla a eona a feletseng ka litekanyetso tse phahameng tsa ho ntša (ho lokolloa ka hora e le 'ngoe kapa ka tlase).
Leha ho le joalo, lisebelisoa li bitsa chelete e ngata ho feta betri ea acid e loto, 'me lisele li na le litekanyetso tse phahameng tsa ho itšehla thajana.
Lisele tsa Ni-Cd tse tiisitsoeng ka nako e 'ngoe li ne li sebelisoa haholo lisebelisoa tsa motlakase tse nkehang habonolo, lisebelisoa tsa ho nka lifoto, mabone, mabone a tšohanyetso, ho itlosa bolutu ka R/C, le lisebelisoa tsa elektronike tse nkehang habonolo.
Bokhoni bo phahameng ba libeteri tsa Nickel-metal hydride, le morao tjena theko ea tsona e tlase, e nketse tšebeliso ea tsona sebaka.
Ho feta moo, tšusumetso ea tikoloho ea ho lahloa ha heavy metal cadmium e kentse letsoho haholo phokotsong ea tšebeliso ea tsona.
Ka hare ho European Union, joale li ka fanoa feela bakeng sa merero e meng kapa bakeng sa mefuta e meng ea lisebelisoa tse ncha joalo ka lisebelisoa tsa bongaka.
Libetri tse kholoanyane tsa NiCd tse nang le moea o pholileng li sebelisoa maboneng a tšohanyetso, matla a standby, le lisebelisoa tsa motlakase tse ke keng tsa senyeha le lits'ebetso tse ling.
Ke Joost Nusselder, mothehi oa Tools Doctor, content marketer, le ntate. Ke rata ho leka lisebelisoa tse ncha, 'me hammoho le sehlopha sa ka esale ke theha lingoloa tse tebileng tsa blog ho tloha 2016 ho thusa babali ba tšepahalang ka lisebelisoa le malebela a ho qapa.
