Intshayelelo:
Iibhetri zeLithiumibe yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla, ukunika amandla yonke into ukusuka kwii-smartphones kunye neelaptops ukuya kwizithuthi zombane kunye neenkqubo zokugcina amandla. Ubuninzi bamandla abo aphezulu, ubomi obude, kunye nendalo ekhaphukhaphu ibenza ukuba babe lukhetho oludumileyo lwezixhobo zombane eziphathwayo kunye nokusetyenziswa kwamandla avuselelekayo. Nangona kunjalo, enye inkalo ebalulekileyo yokusebenzisa iibhetri ze-lithium sisidingo setshaja eyahlukileyo xa kuthelekiswa nezinye iintlobo zeebhetri. Kweli nqaku, siza kuphonononga izizathu ezibangela le mfuneko kunye nokubaluleka kokusebenzisa itshaja ethile kwiibhetri ze-lithium.
Izizathu:
Iibhetri zeLithiumluhlobo lwebhetri ehlaziywayo esebenzisa i-lithium ion njengenxalenye ephambili ye-electrochemical reaction. Ngokungafaniyo neebhetri ze-lead-acid okanye i-nickel-cadmium, iibhetri ze-lithium zisebenza kumbane ophezulu kwaye zineempawu ezithile zokutshaja kunye nokukhupha. Ngenxa yoko, ukusebenzisa itshaja yegeneric eyenzelwe ezinye iindidi zeebhetri kunokukhokelela kwimiba emininzi kunye neengozi zokhuseleko ezinokubakho.
Esinye sezizathu eziphambili zokuba kutheni iibhetri ze-lithium zifuna itshaja eyahlukileyo luvakalelo lwazo lokutshaja kakhulu. Ngokungafaniyo nezinye iintlobo zeebhetri,iibhetri ze-lithiumzinokonakala okanye zibeke umngcipheko wokhuseleko ukuba zihlawuliswe kakhulu. Oku kungenxa yokwakheka kweekhemikhali zeeseli ze-lithium-ion, ezinokungazinzi kwaye ezinokukhokelela ekubalekeni kwe-thermal xa ziphantsi kombane wokutshaja ngokugqithisileyo.
Ngoko ke, ishaja yebhetri ye-lithium ezinikeleyo yenzelwe ukubeka iliso kunye nokulawula inkqubo yokutshaja ukuthintela ukugqithisa kunye nokuqinisekisa ukhuseleko lwebhetri.
Ngaphaya koko, iibhetri ze-lithium zinombane okhethekileyo kunye neemfuno zangoku zokutshaja, ezahlukileyo kwezo zezinye iikhemistri zebhetri. Ukusebenzisa itshaja engazifikeleliyo ezi mfuno kunokubangela ukutshaja okungafanelekanga, ukuncipha kobomi bebhetri, kunye nomonakalo onokwenzeka kwiiseli zebhetri. Itshaja yebhethri ye-lithium ezinikeleyo yenzelwe ukuhambisa amandla ombane achanekileyo kunye namanqanaba akhoyo afunekayo ukutshaja ngokufanelekileyo, ukuqinisekisa ukuba ibhetri ihlawuliswe ngokufanelekileyo nangokukhuselekileyo.
Omnye umba obalulekileyo wokutshaja ibhetri ye-lithium sisidingo sokulungelelanisa iiseli ezingaphakathi kwebhetri. Iipakethi zebhetri yeLithium zineeseli ezininzi eziqhagamshelwe kuthotho kunye nolungelelwaniso oluhambelanayo ukufezekisa umbane ofunekayo kunye nomthamo. Ngexesha lenkqubo yokutshaja, kubalulekile ukulinganisa amandla ombane kunye nemeko yentlawulo yeseli nganye ukuthintela ukutshaja okanye ukutshaja ngaphantsi kweeseli ezithile, nto leyo enokukhokelela ekuthotyweni kokusebenza kunye nemingcipheko yokhuseleko. Itshaja yebhetri ye-lithium ezinikeleyo idibanisa i-bancing circuitry ukuqinisekisa ukuba iseli nganye engaphakathi kwebhetri epakethi ihlawuliswa kwaye ikhutshwe ngokulinganayo, ukwandisa ukusebenza ngokubanzi kunye nobomi bebhetri.
Ukongeza kwiingcamango zobugcisa, i-chemistry yeebhetri ze-lithium nayo idlala indima ebalulekileyo kwimfuno yeshaja eyahlukileyo. Iiseli zeLithium-ion zinejiko elahlukileyo lokukhupha intlawulo xa kuthelekiswa nezinye iikhemistri zebhetri, ezifuna i-algorithm yokutshaja ephucukileyo ukuze kunyuswe inkqubo yokutshaja. Ozinikeleyoibhetri ye-lithiumitshaja ixhotyiswe nge-algorithms yokutshaja ephezulu kunye neenkqubo zokubeka iliso ukulungelelanisa neempawu ezithile zeeseli ze-lithium-ion, ukuqinisekisa ukuba ibhetri ihlawuliswa ngendlela eyandisa ukusebenza kwayo kunye nokuphila ixesha elide.
Ukhuseleko lokutshaja kwebhetri ye-lithium alukwazi ukugqithiswa. Iibhetri zeLithium zinoxinano oluphezulu lwamandla kwaye ziqhelene kakhulu ne-thermal runyiway kunye neminye imiba yokhuseleko ukuba ayihlawuliswanga kakuhle. Ishaja yebhethri ye-lithium ezinikeleyo ibandakanya iimpawu zokhuseleko ezifana nokukhuselwa kwe-overvoltage, ukukhuselwa ngokugqithisileyo, kunye nokubeka iliso lobushushu ukukhusela iingozi ezinokuthi zibekho ngexesha lokutshaja. Ezi ndlela zokhuseleko zibalulekile ekudambiseni imingcipheko ehambelana nokutshaja ibhetri ye-lithium kunye nokuqinisekisa ukhuseleko olupheleleyo lwenkqubo yokutshaja.
Ukuqukumbela
Ukuqukumbela, iimpawu ezizodwa kunye nekhemikhali yeebhetri ze-lithium zifuna ukusetyenziswa kweshaja eyahlukileyo xa kuthelekiswa nezinye iintlobo zeebhetri. Itshaja yebhethri ye-lithium ezinikeleyo yenzelwe ukujongana neemfuno ezithile zokutshaja, ukuqwalaselwa kokhuseleko, kunye neemfuno zokuphucula ukusebenza kweeseli ze-lithium-ion. Ngokusebenzisa itshaja ethile eyenzelwe yonaiibhetri ze-lithium, abasebenzisi banokuqinisekisa ukutshaja okusebenzayo nokukhuselekileyo kweebhetri zabo, ekugqibeleni bakhulise ubomi babo kunye nokusebenza. Njengoko imfuno yeebhetri ze-lithium iqhubeka nokukhula kuwo wonke amashishini ahlukeneyo, ukuqonda ukubaluleka kokusebenzisa itshaja eyahlukileyo kwiibhetri ze-lithium kubalulekile ekukhuthazeni ukusetyenziswa kwebhetri okukhuselekileyo nokusebenzayo.
