Batire ya nickel-cadmium (batire ya NiCd kapena batire ya NiCad) ndi mtundu wa batire yomwe imatha kuchangidwanso pogwiritsa ntchito nickel oxide hydroxide ndi metallic cadmium ngati ma electrode.
Chidule cha Ni-Cd chimachokera ku zilembo za nickel (Ni) ndi cadmium (Cd): chidule cha NiCad ndi chizindikiro cholembetsedwa cha SAFT Corporation, ngakhale dzina lamtunduwu nthawi zambiri limagwiritsidwa ntchito pofotokoza mabatire onse a Ni-Cd.
Mabatire a wet-cell nickel-cadmium anapangidwa mu 1898. Pakati pa matekinoloje a batri omwe amatha kuwonjezeredwa, NiCd inatayika mofulumira gawo la msika mu 1990s, ku mabatire a NiMH ndi Li-ion; msika watsika ndi 80%.
Batire ya Ni-Cd imakhala ndi mphamvu yotha mphamvu ikatulutsa pafupifupi 1.2 volts yomwe imatsika pang'ono mpaka kumapeto kwa kutulutsa. Mabatire a Ni-Cd amapangidwa mosiyanasiyana makulidwe ndi kuthekera, kuchokera kumitundu yosindikizidwa yosinthika yosinthika ndi ma cell owuma a carbon-zinc, kupita ku ma cell akulu otulutsa mpweya omwe amagwiritsidwa ntchito ngati mphamvu yoyimilira ndi mphamvu zopangira.
Poyerekeza ndi mitundu ina ya ma cell omwe amatha kuchangidwanso amapereka moyo wabwino wozungulira komanso magwiridwe antchito pa kutentha kocheperako koma phindu lake lalikulu ndikutha kupereka pafupifupi mphamvu zake zonse zoyezera pamitengo yayikulu yotulutsa (kutulutsa mu ola limodzi kapena kuchepera).
Komabe, zidazo ndi zokwera mtengo kuposa batire ya asidi wotsogolera, ndipo ma cell amakhala ndi ziwopsezo zodzitulutsa okha.
Ma cell a Ni-Cd osindikizidwa nthawi ina ankagwiritsidwa ntchito kwambiri pazida zonyamulika, zida zojambulira zithunzi, tochi, kuyatsa kwadzidzidzi, R/C, ndi zida zamagetsi zonyamulika.
Kuchuluka kwa mabatire a Nickel-metal hydride, komanso kutsika mtengo kwawo posachedwa, kwasintha kwambiri kugwiritsa ntchito kwawo.
Kupitilira apo, kukhudzidwa kwa chilengedwe pakutayidwa kwa heavy metal cadmium kwathandizira kwambiri kuchepa kwa kagwiritsidwe ntchito kake.
Mkati mwa European Union, atha kuperekedwa kokha kuti agwiritse ntchito zina kapena mitundu ina ya zida zatsopano monga zida zamankhwala.
Mabatire akulu akulu otuluka ndi mpweya wonyowa wa ma cell a NiCd amagwiritsidwa ntchito powunikira mwadzidzidzi, magetsi oyimilira, ndi magetsi osadutsika ndi ntchito zina.
Ndine Joost Nusselder, woyambitsa Tools Doctor, content marketer, and dad. Ndimakonda kuyesa zida zatsopano, ndipo pamodzi ndi gulu langa ndakhala ndikupanga zolemba zakuya zamabulogu kuyambira 2016 kuthandiza owerenga okhulupirika ndi zida & malangizo opangira.
