Iibhetri ziza kwiikhemistri ezininzi ezahlukeneyo kunye neentlobo, kunye neendlela ezimbini ezithandwayo ezinokutshajwa kwakhona yi-Li-ion (lithium-ion) ibhetri kunye ne-NiMH (i-nickel-metal hydride) ibhetri.Ngelixa babelana ngeempawu ezifanayo, ibhetri ye-Li-ion kunye nebhetri ye-NiMH inenani leeyantlukwano eziphambili ezenza ukuba zilungele izicelo ezahlukeneyo.Ukuqonda lo mahluko kunokukunceda ukhethe iteknoloji efanelekileyo yebhetri.
Ukuxinana kwamandla: Into ephambili ekukhethweni kwebhetri kukuxinana kwamandla, kulinganiswa kwiiyure ze-watt ngekhilogram (Wh / kg).Iibhetri zeLithium zinika amandla amaninzi aphezulu kuneebhetri zeNiMH.Umzekelo, ibhetri ye-lithium-ion eqhelekileyo ibonelela malunga ne-150-250 Wh / kg, xa kuthelekiswa ne-60-120 Wh / kg ye-NiMH.Oku kuthetha ukuba iibhetri ze-lithium zinokupakisha amandla amaninzi kwindawo elula kunye nencinci.Oku kwenza ukuba iibhetri ze-lithium zilungele ukunika amandla izixhobo zombane ezidibeneyo okanye izithuthi zombane.Iibhetri zeNiMH zininzi kodwa zisaluncedo kwizicelo apho ubungakanani obuncinci bungabalulekanga.
UkuCharge Umthamo: Ukongeza kwi-eneji ephezulu yamandla, iibhetri ze-lithium-ion zikwabonelela ngomthamo omkhulu wentlawulo kuneebhetri ze-NiMH, ngokuqhelekileyo zilinganiswe kwi-1500-3000 mAh ye-lithium vs. 1000-3000 mAh ye-NiMH.Umthamo wentlawulo ephezulu uthetha ukuba iibhetri ze-lithium zinokwenza izixhobo zombane ixesha elide kwintlawulo enye xa kuthelekiswa ne-NiMH.Nangona kunjalo, iibhetri ze-NiMH zisabonelela ngamaxesha amade awoneleyo okusebenza kuninzi lwabathengi be-elektroniki kunye nezixhobo zamandla.
Iindleko: Ngokwexabiso langaphambili, iibhetri ze-NiMH zihlala zitshiphu kuneebhetri ze-lithium-ion.Nangona kunjalo, iibhetri ze-lithium zinobuninzi obuphezulu bamandla, ngoko ufuna iiseli ze-lithium ezimbalwa ukunika amandla isixhobo, esinciphisa iindleko.Iibhetri zeLithium nazo zinobomi obude, ezinye zigcina ukuya kuthi ga kwi-80% yomthamo wazo emva kwe-500 yeejiyile zokutshaja.Iibhetri ze-NiMH zihlala zihlala kuphela kwimijikelezo ye-200-300 ngaphambi kokuhla kwi-70% umthamo.Ngoko ke, ngelixa i-NiMH inokuba neendleko zokuqala eziphantsi, i-lithium inokuba neendleko eziphezulu kwixesha elide.
Ukutshaja: Umahluko obalulekileyo ekutshajweni kwezi ntlobo zimbini zebhetri kukuba iibhetri ze-lithium-ion zineempembelelo zememori encinci, ngokungafaniyo neebhetri ze-NiMH.Oku kuthetha ukuba iibhetri ze-lithium zinokukhutshwa kwaye zitshajwe kwakhona amaxesha amaninzi ngaphandle kokuchaphazela ukusebenza okanye ubomi bebhetri.Nge-NiMH, kungcono ukukhupha ngokupheleleyo kunye nokutshaja ibhetri ukunqanda ukushaja imemori, enokunciphisa umthamo ngokuhamba kwexesha.Iibhetri zeLithium zidla ngokutshaja ngokukhawuleza, ngokwesiqhelo kwiiyure ezi-2 ukuya kwezi-5, xa kuthelekiswa ne-3 ukuya kwiiyure ezi-7 kwiibhetri ezininzi ze-NiMH.
Impembelelo yokusingqongileyo: Ngokuphathelele ubuhlobo bendalo, i-NiMH ineenzuzo ezithile ngaphezu kwe-lithium.Iibhetri ze-NiMH ziqulethe kuphela izinto ezinetyhefu kwaye azinazinyithi ezinzima, ezizenza zingabi yingozi kwindalo esingqongileyo.Zikwanokurisayikilishwa ngokupheleleyo.Iibhetri zeLithium, kwelinye icala, zinetyhefu enzima njengesinyithi se-lithium, i-cobalt, kunye ne-nickel compounds, zibeka umngcipheko wokudubula ukuba zigqithise kakhulu, kwaye okwangoku zineendlela ezimbalwa zokuphinda zisetyenziswe.Nangona kunjalo, iibhetri ze-lithium zigcinakala ngakumbi njengoko kuvela itekhnoloji entsha yebhetri.
