Ukushaja ibhethri ye-lithium kulula ukuqhuma kunebhethri? Iqiniso

Awdur: Iflowpower - Mofani oa Seteishene sa Motlakase se nkehang

Nonke nihamba ngezinyawo, futhi umfowethu omncane uzonginika i-lithium embalwa eyengeziwe. Umqambimanga. Ibhethri ye-lithium-ion ibiza kakhulu.

Ngisathanda ukuqhuma. Akumele uphile! Esikhathini esingeside esidlule, ngixoxe nomphathi emnyango wemoto kagesi, futhi ngathola ikhasimende "elimangalisayo". Lo malume ubheka kuze kufike ku-60 ekhanda lakhe.

Nakuba ingeyinhle kakhulu, ibuye ibe ngumnikazi wayo. Umfowethu omncane ngeke adebeselele ngokwemvelo. Imoto yakamuva imoto encane kagesi ye-turtle king, thenga imoto futhi ishintshiwe, ngaphambi nangemuva, kunezinkulungwane ezinkulu zamadola esitolo.

Umkhulu uthanda ukugibela imoto yebhethri ukuze aphume, futhi agibele ibanga elide ukusuka ePuhuanggu ukuya eTanji Temple. Ukubuya kuzophonsa amakhilomitha ayikhulu amancane, futhi abantu abasha banencane kakhulu. U-Caoyai ufike ngalesi sikhathi eze esitolo ezoshintsha ibhethri elikhulu, ibhethri langaphambilini selisetshenziswe iminyaka engaphezu kwemibili, futhi linamandla kakhulu.

Umabhalane naye uyaxaka, kuyanconywa ukuthi ibhethri ye-lithium-ion yakamuva kamalume, phela i-lithium-ion battery pack yinhle kakhulu, ikhehla lilula kakhulu. Nokho, indoda endala akubonakali uthando, kodwa uqale "imfundo" umabhalane: "Lithium-ion ibhethri kuyingozi kakhulu, ingabe uyaqonda noma ngiyaqonda? Ubheka leyo mililo, wonke amabhethri lithium-ion. Nakuba ibhethri le-lead-acid liyacwila, kodwa selikhululekile.

Ngihamba ngemoto kagesi iminyaka eyishumi. Ibhethri le-lead-acid elifakwe esikhundleni somthofu akuwona amaqembu angu-5. Angikaze ngiye lapho.

Kufanele ngiyishintshe. 7250 lead acid, leyo yi-graphene emnyama, Maji. "Ingozi ye-lead ye-lead ye-lithium-electric inombono walo mbono.

Abaningi bababhali bazoxoxa nomnikazi wesitolo. Umphathi uphinde wathi basebaningi abantu asebeyivezile le nkinga uma bethenga imoto. Kukhona futhi abasebenzisi abathile.

Ngomalume ofanayo, igama lebhethri le-lead-acid alishibhile, futhi owesibili ukhathazekile ngokuthi ibhethri ye-lithium-ion ivutha umlilo. “Kodwa nami ngihamba nemoto encane esebenza ngogesi yeminyaka eyishumi, kanti nemoto eyi-lithium ayidayisi, kodwa-ke mangisho nje ukuthi kukhona okumbalwa engikuzwile, kodwa lowo ngumuntu oshintshe ukushisela. Mntwana, ibhethri langempela linayo ngempela, angikaze ngizwe ngalo.

"Ingabe amabhethri e-lead-acid anokuqhuma komlilo?" “Umbhali wabuza umusho. "Kunento okumele ngiyenze esitolo sethu!" Ubasi uhlabeke umxhwele ngalolu daba. "Ibhethri liyashaja endlini, futhi sekuzophela, ngenhlanhla, akukho nto enkulu.

". “Kodwa-ke, imoto nebhethri esilidayisayo kuyimikhiqizo emikhulu. Ngimbalwa engizwile ukuthi kukhona izinto, kodwa zingamabhethri amadala agaywe kabusha.

Banezingozi eziningi." Umphathi wengeze umusho. Ngemuva kwalokho, umbhali unohlu lwemibuzo lokuphepha kwamabhethri e-lead-acid namabhethri e-lithium-ion.

Imiphumela ibonisa ukuthi abasebenzisi abangu-30% bacabanga ukuthi amabhethri e-lithium-specific lead-acid ayingozi kakhulu, futhi abasebenzisi abacishe babe uhhafu abakwazi ukuqonda okucacile kokuvikeleka kwamabhethri amabili. Ibhethri ye-lithium-ion iyingozi, ingabe kuyiqiniso? Ake sichaze elinye lamabhethri aqhuma? Ukuqhuma kusho ukuphuma kwengcindezi ngokushesha. Ibhethri alivalwa ezimweni eziningi, kungakhathaliseki ukuthi ibhethri ye-lithium ion noma ibhethri le-lead-acid yakhelwe ukwandisa ukungavamile kokucindezela kwangaphakathi, ngisho noma kunomjikelezo omfushane ebhethrini, ingcindezi yangaphakathi izodedelwa ngokushesha, ngeke ibangele izingozi ezinkulu.

Ngakho-ke njengoba ibhethri licabangele ubungozi obungaba khona ekuqaleni kwedizayini, kungani ngokuvamile ubona icala lokuqhuma kwebhethri embikweni wezindaba? Okokuqala, amacala amaningi okuthiwa "ukuqhuma kwebhethri" empeleni akukona ukuqhuma kwebhethri, kodwa izifunda ezimfushane noma ukwehluleka kusilawuli noma ohlelweni lukagesi okubangelwa, lokhu kuqhuma kuncane kakhulu, kukhona imisindo nezinhlansi ezithile kuphela, lokhu umlilo Ungumthombo omkhulu wengozi. Okwesibili, lapho ibhethri noma ezinye izingxenye zemoto zishiswa, abantu abaningi basazoqhunyiswa umzimba wamapulasitiki. Isimo esibucayi kakhulu, ibhethri liqhume ngempela.

Icala elilodwa ukuthi ibhethri elingaphansi ngokwalo aliklami i-valve yokuphepha noma i-valve yokuphepha ilimele, futhi ayikwazi ukusetshenziswa. Lapho umfutho wangaphakathi webhethri ungaphezu kwamandla, ukuqhuma. Esinye isimo ukuthi iphutha leshaja yebhethri lishajwe ngokweqile, futhi i-hydrogen ingena ngaphakathi ebhethrini.

Lapho i-hydrogen nomoya-mpilo kuxutshwa ngemva kokuhlangana kwengxenye ethile. Ibhethri ye-lithium-ion iyingozi ngempela kunamabhethri e-lead-acid? Iqiniso alinjalo njengoba ukuqonda kwebhethri kuzoqhuma, okuyinto ephephile ebhethri ye-lithium-ion kanye nebhethri le-lead-acid? Kusukela esakhiweni sebhethri, iphakethe lebhethri le-lithium-ion lamanje liyapakishwa ngokuyisisekelo, futhi ibhethri le-asidi yomthofu empeleni liyibhethri le-asidi eholayo elingalondolozi, uma ukucindezela kwalo kwangaphakathi kukhulu kakhulu, kanye nevalvu yokuphepha ingavamile. Uma i-coefficient yengozi kokubili ngokuyisisekelo.

Uma ibhethri lishajwe ngokweqile, okuqukethwe kwe-electrolyte ebhethrini lika-18650 kulinganiselwe, futhi inani lemvula ye-hydrogen nalo lilinganiselwe kakhulu, kodwa mayelana nebhethri le-lead-acid ku-electrolyte ye-dilute sulfuric acid, uma kwenzeka, i-hydrogenation yangaphakathi yebhethri iyenzeka. Lesi simo sibucayi, namathuba okungqongqoza nawo ande kakhulu. Ngokombono wephoyinti lokuvikela ukuphepha kwebhethri, i-valve yokuphepha yakhelwe ebhethrini elingu-18650, elingakwazi kuphela ukukhulula ukucindezela okukhulu kwangaphakathi, kodwa futhi nokunqamula ngokomzimba ibhethri noxhumo lwesekethe yangaphandle, okulingana nokuhlukanisa ibhethri ngokomzimba ukuze kuqinisekiswe ukuphepha kwephakheji yebhethri.

Ngaphezu kwalokho, iphakethe lebhethri le-lithium-ion ngokuvamile lifakwe isivikeli se-BMS. Ingakwazi ukulawula ngokunembile isimo sebhethri ngalinye, ixazulule ngokuqondile inkinga yokukhishwa ngokweqile. Ngokuphambene nalokho, amabhethri e-lead-acid abonakala efakazelwa ukuvikelwa kokuphepha ngaphezu kwe-valve yokuphepha, ukuvikelwa kwe-BMS kunokuncane, futhi amashaja amaningi aphansi angagcwaliswa ngisho nokuhluleka kwamandla, iziqinisekiso eziphephile namabhethri e-lithium-ion.

Yiqiniso, uma usebenzisa ibhethri ye-lithium-ion cishe inani namabhethri e-lead-acid, lesi simo asikwazi ukukusindisa. Ekugcineni, kukhona okuncane, uma kungenxa yokuthi ukungqubuzana okungalindelekile kubangela ukubhujiswa kwesakhiwo sebhethri, ibhethri ye-lead-acid ibonakala ivikeleke kakhulu kunebhethri ye-lithium-ion. Kodwa-ke, kuleli zinga lezingozi, izinto zebhethri sekuyisikhathi eside zivezwe ezindaweni ezivulekile, futhi azizange zikhulume ngokuqhuma.

Isifinyezo: Ibhethri alikona ukuqhuma kwebhomu, okwenza imikhiqizo esezingeni eliphansi ibone idizayini yokuphinda ingasebenzi ebhethrini. Ibhethri le-lithium-ion elifanelekayo nebhethri le-lead-acid lingaqinisekisa ngokugcwele ukuphepha komsebenzisi, futhi awukho umehluko obalulekile wokuphepha. Kodwa-ke, ngenxa yenani elikhulu lezimoto zikagesi ezincane ezisezingeni eliphansi kanye nama-skateboards emakethe, iningi lazo lisebenzisa ibhethri ye-lithium-ion enekhwalithi ephansi, elula kakhulu, lokhu kubuye kushiye ibhethri ye-lithium-ion ingavikelekile kubathengi.
