Kwihlabathi lobuchwepheshe bebhetri,iibhetri ze-nickel-metal hydride (NiMH)kunye neebhetri ze-lithium-ion (Li-ion) ziindlela ezimbini ezidumileyo. Uhlobo ngalunye lubonelela ngeenzuzo ezizodwa, okwenza ukhetho phakathi kwazo lube lubalulekile kwiintlobo ngeentlobo zezicelo. Eli nqaku libonelela ngothelekiso olupheleleyo lweenzuzo zeebhetri ze-NiMH ngokuchasene neebhetri ze-Li-ion, ngelixa likwaqwalasela imfuno yemarike yehlabathi kunye neendlela ezisetyenziswayo.
Iibhetri zeNiMH zinamandla amaninzi, oko kuthetha ukuba zinokugcina amandla angakumbi. Ukongeza, zitshaja ngokukhawuleza kwaye zihlala ixesha elide xa kuthelekiswa nezinye iintlobo zeebhetri. Oku kuthetha ukuba zichitha ixesha elincinci zitshaja kwaye zisebenza ixesha elide. Ngaphezu koko, iibhetri zeNiMH zinempembelelo encinci kwindalo esingqongileyo ngenxa yokungabikho kwezinto ezinobungozi ezifana ne-cadmium.
Kwelinye icala, iibhetri zeLi-ion zineengenelo ezininzi. Okokuqala, zinamandla aphezulu, nto leyo evumela amandla amaninzi kwiphakheji encinci. Oku kuzenza zilungele izixhobo ezincinci ezifuna ixesha elide lokusebenza. Okwesibini, ii-electrode kunye nekhemistri yazo zibonelela ngobomi obude xa kuthelekiswa neebhetri zeNiMH. Ngaphezu koko, ubungakanani bazo obuncinci buvumela izixhobo ezithambileyo neziphathekayo.
Xa kufikwa kukhuseleko, zombini ezi ntlobo zeebhetri zinento ezicinga ngayo.Iibhetri zeNiMHinokubangela umngcipheko womlilo phantsi kweemeko ezinzima kakhulu, iibhetri zeLi-ion zinotyekelo lokutshisa kakhulu kwaye zibambe umlilo ukuba zitshajwe ngendlela engafanelekanga okanye ngenxa yomonakalo. Ke ngoko, amanyathelo afanelekileyo okhathalelo kunye nokhuseleko ayimfuneko xa usebenzisa zombini ezi ntlobo zeebhetri.
Xa kufikwa kwimfuno yehlabathi, imeko iyahluka ngokuxhomekeke kummandla. Amazwe aphuhlileyo afana ne-US neYurophu athanda ukukhetha iibhetri ze-Li-ion kwii-elektroniki zawo eziphezulu ezifana nee-smartphone, iitablet, kunye neelaptop. Ukongeza, ngeziseko zokutshaja ezisele zikho kwezi ndawo, iibhetri ze-Li-ion zikwasetyenziswa kwizithuthi zombane (ii-EV) kunye nee-hybrids.
Kwelinye icala, amazwe aseAsia afana neTshayina neIndiya akhetha iibhetri zeNiMH ngenxa yokuba zisebenza kakuhle kwaye kulula ukutshaja. Ezi bhetri zisetyenziswa kakhulu kwiibhayisekile zombane, izixhobo zamandla, kunye nezixhobo zasekhaya. Ukongeza, njengoko iziseko zokutshaja eAsia ziqhubeka nophuhliso, iibhetri zeNiMH nazo ziyasetyenziswa kwii-EV.
Lilonke, iibhetri zeNiMH kunye neLi-ion nganye zibonelela ngeenzuzo ezizodwa ngokuxhomekeke kwisicelo kunye nommandla. Njengoko imakethi ye-EV isanda kwihlabathi liphela kwaye i-elektroniki yabathengi itshintsha, imfuno yeebhetri zeLi-ion kulindeleke ukuba ikhule. Okwangoku, njengoko itekhnoloji iphucuka kwaye iindleko ziyancipha,Iibhetri zeNiMHzisenokugcina ukuthandwa kwazo kwiindawo ezithile.
Ukuqukumbela, xa ukhetha phakathi kweebhetri zeNiMH kunye neLi-ion, kubalulekile ukuqwalasela iimfuno zakho ezithile: uxinano lwamandla, ubomi bokuphila, imida yobukhulu, kunye neemfuno zebhajethi. Ukongeza, ukuqonda izinto ozikhethayo zengingqi kunye neendlela zemarike kunokukunceda wenze isigqibo sakho. Njengoko itekhnoloji yebhetri iqhubeka nokutshintsha, kusenokwenzeka ukuba zombini iibhetri zeNiMH kunye neLi-ion ziya kuhlala zikhetho ezibalulekileyo kwizicelo ezahlukeneyo kwixesha elizayo.
