Ibhethri le-nickel-cadmium (ibhethri le-NiCd noma ibhethri le-NiCad) liwuhlobo lwebhethri elishajekayo lisebenzisa i-nickel oxide hydroxide ne-metallic cadmium njengama-electrode.
Isifinyezo esithi Ni-Cd sisuselwa kuzimpawu zamakhemikhali ze-nickel (Ni) ne-cadmium (Cd): isifinyezo esithi NiCad wuphawu lokuthengisa olubhalisiwe lwe-SAFT Corporation, nakuba leli gama lomkhiqizo livame ukusetshenziswa ukuchaza wonke amabhethri e-Ni-Cd.
Amabhethri e-nickel-cadmium e-Wet-cell asungulwa ngo-1898. Phakathi kobuchwepheshe bebhethri obushajekayo, i-NiCd yalahlekelwa ngokushesha isabelo semakethe ngawo-1990, kumabhethri e-NiMH kanye ne-Li-ion; isabelo semakethe sehle ngo-80%.
Ibhethri le-Ni-Cd line-voltage yetheminali phakathi nokukhipha cishe ama-volts angu-1.2 eyehla kancane kuze kube sekugcineni kokuphuma. Amabhethri e-Ni-Cd enziwa ngezinhlobonhlobo zosayizi nekhono, kusukela ezinhlotsheni eziphathwayo ezivaliwe ezishintshwayo namaseli omile we-carbon-zinc, kuya kumaseli amakhulu angena umoya asetshenziselwa amandla okulinda namandla ashukumisayo.
Uma kuqhathaniswa nezinye izinhlobo zamaseli aphinde ashajwe anikeza ukuphila komjikelezo omuhle nokusebenza emazingeni okushisa aphansi anomthamo ofanelekile kodwa inzuzo yawo ebalulekile ikhono lokuletha umthamo wawo olinganiselwe ophelele ngamanani aphezulu okukhipha (ukuphuma ngehora elilodwa noma ngaphansi).
Nokho, izinto zokwakha zibiza kakhulu kunebhethri le-asidi yomthofu, futhi amangqamuzana anezinga eliphezulu lokuzikhipha.
Amaseli e-Ni-Cd avaliwe ngesinye isikhathi ayesetshenziswa kakhulu kumathuluzi kagesi aphathwayo, okokusebenza kwezithombe, amathoshi, izibani eziphuthumayo, i-R/C yokuzilibazisa, kanye nezinto zikagesi eziphathwayo.
Amandla aphezulu amabhethri e-Nickel-metal hydride, kanye nezindleko zawo eziphansi kamuva nje, athathele indawo ukusetshenziswa kwawo.
Ngaphezu kwalokho, umthelela wemvelo wokulahlwa kwe-cadmium yensimbi esindayo ube negalelo elikhulu ekwehliseni ukusetshenziswa kwayo.
Ngaphakathi kwe-European Union, manje anganikezwa kuphela ngezinjongo zokushintshwa noma ngezinhlobo ezithile zezisetshenziswa ezintsha ezifana nemishini yezokwelapha.
Amabhethri e-NiCd amakhulu anomoya ongenisa umoya asetshenziswa ekukhanyisweni kwesimo esiphuthumayo, emandleni abekwe eceleni, namandla kagesi angaphazamiseki nezinye izinhlelo zokusebenza.
Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
