Ukuziqonda Kwezinkilinga Ezikhubazekayo Kwi-Chemistry ye-Battery Efanayo
Ubuthi obuncedisiwe ngamphopho intekhnoloji yashintsha izinqumo zokugcina amandla kwiindustri ezininzi, kusukwa kumakhina athinta amandla kuze kube ngumathuba wokuphila kwamandla. Kuyisiseko sokusebenza kwezibhamu eziphucileyo phakathi kweempawu ezahlukeneyo zokuchitha kuyimfihlelo ekhethekileyo kulayini nesimilo sangaphambili. Xa sifaka ngapha kweengcinga zokuchitha zezibhamu ze-lithium phosphate, sizakuhlola njani le mali ibeke inyaniso nokulungiswa kwiimpawu ezahlukeneyo zokuchitha.
Ukunikezela Kwemfihlelo Yempawu Yokuchitha
Ukusebenza Kwizulu Elibusha
Ukuziphatha kwebhamu ye-lithium phosphate emva kwezulu elibusha kubonisa ububele obuhle kunye nabhamu eziphucileyo. Xa iimpawu zokuchitha ziphumaza phantsi kwezinga lokuchitha, le bhamu ziqinisekisa inyaniso eyinkimbinkimbi yesimo, zisebenzisa ngokwaneleyo kwi-80% kwi-0°C (32°F). Umfanekiso ovela kwi-phosphate uphinde ufake ubunzima, ukwenzela ukusebenza okuthembekileyo nakaphakade kwezulu elibusha.
Abasebenzi basebenzini baphindiswe izinhlelo zokuphatha ubuchwepheshe ukuze kugcinwe imizwa yezulu. Lezi zinhlelo zasiza ukugcina ubuchwepheshe besimilo sangaphakathi kwemitholampofu, ukuqinisekisa ukulethwa kwezindleko ngokuvamile nokukhuthaza ukungabi khona kwezimali. Ukubalwa kwegesi yesilikonphosphate kusiza futhi ekulondolozeni kwayo emva kokushisa, ngaphansi kwebuciko obuncane bezibhamu zelithiyamu ezikwenzela ukuba kube nengqondo.
Iinkenkelo Zokushisa Kakhulu
Emva kokushisa okuphakade, i-inthanethi yezimbili zelithiyam-phosphate zibonisa ubunzima obukhulu. Isilinganiso sokushisa kwezi zimbili zihlala siyafika ku-60°C (140°F), okukhulu kunesikhathi eside kunazo zonke izinhlelo zokubalwa kwezimbili. Lokhu kumele kubakhazimula kakhulu kususelwa kumthelela wokuzinziswa kwe-cathode yokubalwa kwe-phosphate, eyayishisa ngaphezu kwezinye izinhlelo zelithiyam-ion.
Ngemva yokusebenza kweminyaka engcwele, le minyakathyela ihlala isebenza ngokuthi ngekho ukungabi nomdla. I-chemistry yephosphate isivikela ukungavaleki kwe-oksijini ema-temperatshini aphezulu, okuyisithuba esibalulekile sokhuseleko esihlenza le minyakathyela sibe yisiko sezigaba eziphilayo emaqeni amandla. Izinkundla zokulahlaza ezimiswe kakhulu zazinzisa izici zabo ze-temperature, ihlinzekisa ukusebenza kahle emazingeni aphikisanayo.
Izici Zokhuseleko Nokuphatha Umthwalo Wokugcwalisa
Izinqumo Ezifakelwe Ngaphakathi Sokukhuseleka
Izinhlelo zakamuva zeminjakathela ye-lithium phosphate zifaka izigaba eziningi zezici zokhuseleko ukuze ziphathe izimo ezihlukene zempihla. Kuzo kufaka izinhlelo ezihlelekile zokuphatha iminyakathyela (BMS) ebalwa ngcono izindlela zeminyakathyela futhi zilungise izilinganiso zokulayisha nokunqamula ngendlela efanele. Ubunzima bokushisa obubonakalayo be-phosphate chemistry bufa okuthile kokhuseleko, kuhlenza le minyakathyela ibe nemiphumela eyinhambili kakhulu kumathuba wokugcwalisa.
Abakhi baphatha indlela yokubeka i-coating nezimboni zokuhlukanisa ezingcolile ukuthi zilindele kakhulu emva kwezilingo ezininzi. Lezi zinto zihlanza ngokuhlanganisa ukuze kugwenselwe izikhathi ezifushane phakathi futhi zilondolozo kakhulu noma kuzo zonke izimo eziphathelene nomthubi. Ubunzima bezigaba le-lithium phosphate bezifaka izindlela zokulahlela ingcindezi nezinceku zomthubi njengemisebenzi eyengeziwe yokuphepha.
Izinhlelo Zokukhangelwa Kwegunya Lokumiswa
Izinhlelo ezihlelekile yokuphatha umthubi ziduma indima ekhethekile ekulondolozeni iqiniso elihle le-battery. Izinhlelo zokulahla umthubi, ikakhulu kuzo zonke izinhlelo zezinhlu eziphathekayo, zisiza ekulahliseni umthubi ngendlela efanele futhi ukuze kugwenselwe izindawo ezine-heat ephakeme. Lezi zinhlelo zihlola ubomi bomthubi, zibangela ukuba kube namandla amandla futhi zilondolozo iqiniso elihle kuzo zonke izimo zomhlaba.
Amathithimba efanekiso lokuphatha umthwalo kahle ayisohlisa izivumelwano zokulayisha ngokulinganisa nokufunda kwezinkelingo, ukuqinisekisa ukusebenza kahle nokuhlelekile. Ngemikhathi yezulu ezihlukile, le minyango ingakhiqizeli iphakheji le-battery, ibaphilise kakhulu emkhumbini noma ibashishilise kakhulu emva kokugcina phambi kokusetshenziswa. Lokhu kusikwa okuqhubekayo kunciphisa ubude bebuso baka-battery bese kubuyisela ukusebenza kahle nguye yoni.
Ukuphila kude kanye nokusebenza okuhle
Ukungcoliswa Kokucazwa
Ukutholakala kwesinkelingo kubangelisa kakhulu ubude bebuso becycle ye-battery ye-lithium phosphate. Uma isetshenziswa ngaphandle kwezinkinga ezivumelekile, lezi battery zingafinyelela izilinganiso ezinhle zokugeza futhi ukulaya kancane kancane ezintweni ezingaphezu kuka-2000 bese zibambe inkinga eyi-80% yesilinganiso. Isakhiwo esiqinephisiwe sakhe se-crystal se-phosphate cathode sinesizo esikhulu kulelo ubude bebuso obunempilo.
Ukuthi kuthakathelwa kakhulu kusigaba esiphazanyayo kungahlukana ngokuphindaphindiwe kwezinsimbi, kodwa izinhlelo zokuphatha ubomi bezici zisenza ukuthi kuhlukane kancane. Izinkolelo zange zibonise ukuthi izibhubhu zelithiyamu fosfethi zilondoloza ikhayiphasithi ngempela kunazo ezinye izinhlelo zelithiyamu-ayoni, kudinga kuthi kubekwe phansi imizwa yosigaba sezulu.
Izinkcazo Zokwesabala
Umehluko wezibhubhu zelithiyamu fosfethi uphendula kakhulu kumculo wabo wesigaba sezulu. Ukuphatha isigaba sezulu ngempela ngexesha lokusebenza nokugcina kwenza umthelela mkhulu kumsebenzi wawo emuva kweminyaka. Lezi zibhubhu zibonisa ukuthi kuncane kakhulu ukwesabala ngexesha uma kugcinwa emsigabaneni ophelele, noma kunye nezinhlelo ebonisa ukuthi kukhula okuncane kune-3% ngonyaka.
Imithombo emiswe ngokuphelele ihlinza ububi bwebhatereyi futhi iyisimise amatholi okusebenza ukuze kugcinwe ubude bezinhlalo. Le ndlela eyisandulayo isiza ekugcineni imisebenzi engafanelekile noma kusheshi kwebhatereyi, ihlinza ukusebenza kahle kuqophela inhlalo yalo. Ukulungiswa okuqhubekayo nokulungiswa kwemali yesilinganiso kusiza ekunikelweni webhatereyi inhlalo ephakeme kunazo ezinye izinkomba.
Imibuzo Evame Ukubuzwa
Yini indawo yokusebenza kahle kwebhatereyi ye-lithium phosphate?
Indawo eqondene yokusebenza kwebhatereyi ye-lithium phosphate iphakathi kwe-20°C kuya ku-45°C (68°F kuya ku-113°F). Phakathi kalesi sikhala, webhatereyi ihlinza imisebenzi, ukusebenza kahle, nezinhloso zange kude. Kodwa, lezi zibhatereyi zingasebenza phakathi kwezigaba eziningi zezinkamba ngokulungiswa kwezinhlelo zokulungiswa.
Kanjani okushisa okukhulu kubangelisa ububi bwebhatereyi?
Emehluko ephelele kakhulu, amabhethri yesilithiyam phasphethi ayathola ubuncinane bokuthile kwezimali, ngokuvamile kubuyisela izimali ezingu-70-80% zezimali zakhe ezenzulwini nge-0°C (32°F). Lomdalo unembile, futhi izimali zonke zibuyela uma ibhethri ivuselela emoyeni wemisebenzi yayo. Izinhlelo zokuvuselela kuqala zingasiza ekulungiseni imiphimpi yokusebenza kwemvula embi.
Ukuthempirichaa okuphelele kungayihlukanisa ngokudala ibhethri?
Nakuba amabhethri ase-silithiyam asenziwa phasphethi anesandla esikhulu ekukhathazekeni kwezimali, ukubanikwa kusetempirichaa okuphakathi kusuka phezu kwe-60°C (140°F) kungaholela ekushisheni kwezinsuku zabo nokuthi kungabeka isilingo emsulwa wabhethri. Kodwa, ubunzima bawo besandla nobunikazi obufakiwe ngaphakathi bakhunguza ukuthi kuhlahleke kube lula kakhulu noma kumele kumele kakhulu.
