Ibhetri yenickel-cadmium (ibhetri yeNiCd okanye ibhetri yeNiCad) luhlobo lwebhetri egcwalisekayo kusetyenziswa nickel oxide hydroxide kunye nemetallic cadmium njengee-electrode.
Isishunqulelo esithi Ni-Cd sithatyathwe kwiisimboli zekhemikhali zenikeli (Ni) kunye ne-cadmium (Cd): isishunqulelo esithi NiCad luphawu lokuthengisa olubhalisiweyo lwe-SAFT Corporation, nangona eli gama lohlobo lidla ngokusetyenziswa ukuchaza zonke iibhetri ze-Ni-Cd.
Iibhetri ze-nickel-cadmium ezimanzi zaqanjwa ngo-1898. Phakathi kobuchwepheshe bebhetri obuhlawulelwayo, i-NiCd yalahlekelwa ngokukhawuleza isabelo semarike kwiminyaka yee-1990, kwiibhetri ze-NiMH kunye ne-Li-ion; isabelo semarike sehle ngama-80%.
Ibhetri ye-Ni-Cd ine-terminal voltage xa ikhutshwa malunga ne-1.2 volts ehla kancinci de iphantse yaphela. Iibhetri ze-Ni-Cd zenziwe kuluhlu olubanzi lobukhulu kunye nobuchule, ukusuka kwiintlobo eziphathwayo ezitywiniweyo ezinokutshintsheka kunye neeseli ezomileyo ze-carbon-zinc, ukuya kwiiseli ezinkulu ezisetyenziselwa ukulinda amandla kunye namandla ashukumisayo.
Xa kuthelekiswa nezinye iindidi zeeseli ezitshajwayo zinika ubomi bomjikelo olungileyo kunye nokusebenza kumaqondo obushushu aphantsi kunye nomthamo ofanelekileyo kodwa inzuzo yayo ebalulekileyo kukukwazi ukuhambisa ngokufanelekileyo umthamo wayo olinganisiweyo opheleleyo kumazinga aphezulu okukhutshwa (ukukhupha ngeyure enye okanye ngaphantsi).
Nangona kunjalo, izixhobo zibiza kakhulu kunebhetri ye-asidi ye-lead, kwaye iiseli zinezinga eliphezulu lokuzikhupha.
Iiseli ze-Ni-Cd ezitywiniweyo zazisetyenziswa kakhulu ngaxeshanye kwizixhobo zombane eziphathwayo, izixhobo zokufota, iithotshi, ukukhanya okungxamisekileyo, ukuzonwabisa kwe-R/C, kunye nezixhobo zombane eziphathwayo.
Umthamo ophakamileyo weebhetri ze-Nickel-metal hydride, kwaye kutshanje iindleko zazo eziphantsi, ubukhulu becala ziye zathatha indawo yokusetyenziswa kwazo.
Ngaphaya koko, impembelelo yokusingqongileyo yokulahlwa kwecadmium yentsimbi enzima ibe negalelo elikhulu ekunciphiseni ukusetyenziswa kwazo.
Ngaphakathi kwiManyano yaseYurophu, ngoku zinokubonelelwa kuphela ngeenjongo zokutshintsha okanye iintlobo ezithile zezixhobo ezitsha ezifana nezixhobo zonyango.
Iibhetri ezinkulu zeNiCd ezingenisa umoya ezimanzi zisetyenziswa kwizibane ezingxamisekileyo, amandla alindileyo, kunye nonikezelo lwamandla olungaphazamisekiyo kunye nezinye iinkqubo.
NdinguJoost Nusselder, umseki weZixhobo zeGqirha, umthengisi womxholo, kunye notata. Ndiyathanda ukuzama izixhobo ezitsha, kwaye kunye neqela lam ndiye ndenza amanqaku ebhlog anzulu ukusukela ngo-2016 ukunceda abafundi abathembekileyo ngezixhobo kunye neengcebiso zokwenza.
