Iibhetri zeLithiumziye zaba yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla, zinika amandla yonke into ukusuka kwiifowuni eziphathwayo kunye neelaptops ukuya kwizithuthi zombane kunye neenkqubo zokugcina amandla. Ubuninzi bazo bamandla aphezulu, ubomi obude, kunye nokukhanya kwazo kuzenza zibe lukhetho oludumileyo lwezixhobo ze-elektroniki eziphathwayo kunye nokusetyenziswa kwamandla avuselelekayo. Nangona kunjalo, enye into ebalulekileyo yokusebenzisa iibhetri ze-lithium kukufuneka kwetshaja eyahlukileyo xa kuthelekiswa nezinye iintlobo zeebhetri. Kweli nqaku, siza kuhlola izizathu zale mfuneko kunye nokubaluleka kokusebenzisa itshaja ethile kwiibhetri ze-lithium.
Izizathu:
Iibhetri zeLithiumluhlobo lwebhetri etshajwayo esebenzisa ii-ion ze-lithium njengenxalenye ephambili yempendulo yayo ye-electrochemical. Ngokungafaniyo neebhetri zemveli ze-lead-acid okanye ze-nickel-cadmium, iibhetri ze-lithium zisebenza kwiivolthi eziphezulu kwaye zineempawu ezithile zokutshaja nokukhupha. Ngenxa yoko, ukusebenzisa itshaja eqhelekileyo eyenzelwe ezinye iintlobo zeebhetri kunokukhokelela kwiingxaki ezininzi kunye neengozi ezinokubakho zokhuseleko.
Esinye sezizathu eziphambili zokuba iibhetri ze-lithium zifuna itshaja eyahlukileyo kukuba zinobuthathaka ekutshajeni kakhulu. Ngokungafaniyo nezinye iintlobo zeebhetri,iibhetri ze-lithiumzingonakala okanye zibe nomngcipheko wokhuseleko ukuba zitshajiswa kakhulu. Oku kungenxa yokwakheka kweekhemikhali zeeseli ze-lithium-ion, ezinokuthi zingazinzi kwaye zikhokelele ekubalekeni kobushushu ukuba ziphantsi kwe-voltages yokutshaja egqithisileyo.
Ngoko ke, itshaja yebhetri ye-lithium eyenzelwe ngokukodwa yenzelwe ukujonga nokulawula inkqubo yokutshaja ukuthintela ukutshaja kakhulu nokuqinisekisa ukhuseleko lwebhetri.
Ngaphezu koko, iibhetri ze-lithium zineemfuno ezithile ze-voltage kunye ne-current zokutshaja, ezahlukileyo kwezo zezinye iikhemikhali zebhetri. Ukusebenzisa itshaja engahlangabezani nezi mfuno kunokubangela ukutshaja okungasebenzi kakuhle, ukunciphisa ixesha lebhetri, kunye nomonakalo onokubakho kwiiseli zebhetri. Itshaja yebhetri ye-lithium eyenzelwe ukubonelela nge-voltage echanekileyo kunye namanqanaba afunekayo ukuze kutshajwe ngokufanelekileyo, ukuqinisekisa ukuba ibhetri itshajwa ngokufanelekileyo nangokukhuselekileyo.
Enye into ebalulekileyo yokutshaja ibhetri ye-lithium yimfuneko yokulinganisela iiseli nganye nganye ngaphakathi kwepakethi yebhetri. Iipakethi zebhetri ye-lithium ziqulathe iiseli ezininzi ezidityaniswe ngochungechunge kunye nolungelelwaniso oluhambelanayo ukuze kufezekiswe i-voltage kunye nomthamo ofunekayo. Ngexesha lenkqubo yokutshaja, kubalulekile ukulinganisela i-voltage kunye nemeko yetshaja yeseli nganye nganye ukuthintela ukutshaja kakhulu okanye ukutshaja ngaphantsi kweeseli ezithile, okunokukhokelela ekuwohlokeni kokusebenza kunye nemingcipheko yokhuseleko. Itshaja yebhetri ye-lithium ezinikeleyo ibandakanya i-balance circuitry ukuqinisekisa ukuba iseli nganye ngaphakathi kwepakethi yebhetri itshaja kwaye ikhutshwa ngokulinganayo, nto leyo ekhulisa ukusebenza kunye nobomi bebhetri iyonke.
Ukongeza kwizinto zobugcisa, ikhemistri yeebhetri ze-lithium ikwadlala indima ebalulekileyo ekufuneni itshaja eyahlukileyo. Iiseli ze-lithium-ion zine-curve eyahlukileyo yokukhupha itshaja xa kuthelekiswa nezinye iikhemistri zebhetri, zifuna i-algorithm yokutshaja ephucukileyo ukuze kuphuculwe inkqubo yokutshaja.ibhetri ye-lithiumItshaja ixhotyiswe nge-algorithms zokutshaja eziphambili kunye neenkqubo zokubeka esweni ukuze zihambelane neempawu ezithile zeeseli ze-lithium-ion, ukuqinisekisa ukuba ibhetri itshajwa ngendlela eyandisa ukusebenza kwayo kunye nobude bayo.
Ukhuseleko lokutshaja kwebhetri ye-lithium alunakubalwa. Iibhetri ze-lithium zinamandla aphezulu kwaye zisengozini yokubaleka kobushushu kunye neminye imiba yokhuseleko ukuba azitshajwanga ngokufanelekileyo. Itshaja yebhetri ye-lithium ezinikeleyo ibandakanya iimpawu zokhuseleko ezifana nokukhusela i-overvoltage, ukhuseleko lwe-overcurrent, kunye nokubeka iliso kubushushu ukuthintela iingozi ezinokubakho ngexesha lenkqubo yokutshaja. Ezi ndlela zokhuseleko zibalulekile ekunciphiseni iingozi ezinxulumene nokutshaja kwebhetri ye-lithium kunye nokuqinisekisa ukhuseleko olupheleleyo lwenkqubo yokutshaja.
Isiphelo
Ukuqukumbela, iimpawu ezizodwa kunye nekhemistri yeebhetri ze-lithium zifuna ukusetyenziswa kwetshaja eyahlukileyo xa kuthelekiswa nezinye iintlobo zeebhetri. Itshaja yebhetri ye-lithium eyenzelwe ukujongana neemfuno ezithile zokutshaja, izinto eziqwalaselweyo zokhuseleko, kunye neemfuno zokuphucula ukusebenza kweeseli ze-lithium-ion. Ngokusebenzisa itshaja ethile eyenzelweiibhetri ze-lithium, abasebenzisi banokuqinisekisa ukuba iibhetri zabo ziyatshajwa ngokufanelekileyo nangokukhuselekileyo, ekugqibeleni ziphucule ubomi bazo kunye nokusebenza kwazo. Njengoko imfuno yeebhetri ze-lithium iqhubeka ikhula kumashishini ahlukeneyo, ukuqonda ukubaluleka kokusebenzisa itshaja eyahlukileyo yeebhetri ze-lithium kubalulekile ekukhuthazeni ukusetyenziswa kwebhetri ngokukhuselekileyo nangokusebenzayo.
