Ukubuka konke kwamabhethri we-nickel-hydrogen: Ukuhlaziywa kokuqhathanisa ngamabhethri e-lithium-ion

Ukuqalisa

Njengoba ukufunwa kwezixazululo zokugcina amandla kuyaqhubeka ukukhuphuka, ubuchwepheshe obuhlukahlukene bebhethri buhlolwa ukusebenza kwabo, isikhathi eside, kanye nomthelela wezemvelo. Phakathi kwalokhu, amabhethri we-nickel-hydrogen (NI-H2) anaka njengendlela esebenzayo ebhethri elisetshenziswa kakhulu le-lithium-ion (li-ion). Lo mbhalo uhlose ukuhlinzeka ngokuhlaziywa okuphelele kwamabhethri we-NI-H2, uqhathanisa nezinzuzo nezinzuzo zawo kanye namabhethri e-Li-Ion.

Amabhethri we-nickel-hydrogen: Ukubuka konke

Amabhethri we-nickel-hydrogen asetshenziswe ngokuyinhloko kwizicelo ze-aerospace selokhu zaqalwa ngawo-1970. Ziqukethe i-nickel oxide hydroxide electrode emihle, i-electrode ye-hydrogen neclector, ne-electrolyte ye-alkaline. Lawa mabhethri ayaziwa ngamandla abo aphezulu amandla aphezulu kanye namandla okusebenza ngaphansi kwezimo ezimbi kakhulu.

Izinzuzo zamabhethri we-nickel-hydrogen

1. Impilo ende kanye nomjikelezo impilo: Amabhethri we-NI-H2 abonisa impilo yomjikelezo ophakeme ngokuqhathaniswa namabhethri e-Li-Ion. Bangakwazi ukubekezelela izinkulungwane zemijikelezo yokukhipha umsubathi, okwenza balungele izinhlelo zokusebenza ezidinga ukuthembeka kwesikhathi eside.
2. Ukuqina kokushisa: Lawa mabhethri enza kahle ebangeni lokushisa elibanzi, ukusuka ku-40 ° C kuya ku-60 ° C, elizuzisa izinhlelo ze-aerospace kanye nezempi.
3. Ukuphepha: Amabhethri we-NI-H2 athambekele kangako ekubalekeni okushisayo okuqhathaniswa namabhethri e-Li-Ion. Ukungabikho kwama-electrolyte avuthayo kunciphisa ubungozi bomlilo noma ukuqhuma, okwenza ngcono ukuphepha kwabo.
4. Umthelela wezemvelo: I-nickel ne-hydrogen kuningi futhi kuyingozi enkulu kune-lithium, cobalt, nezinye izinto ezisetshenziswa kumabhethri e-li-ion. Lesi sici sinomthelela onyaweni oluphansi lwezemvelo.

Okubi kwamabhethri we-nickel-hydrogen

1. Ubuningi bamandla: Ngenkathi amabhethri we-NI-H2 anobunzima obuhle bamandla, ngokuvamile awela nje amandla obuningi anikezwe amabhethri e-li-ion, anciphisa ukusetshenziswa kwawo kuhlelo lokusebenza lapho isisindo nobukhulu kubalulekile.
2. Khokhisa: Ukukhiqizwa kwamabhethri we-NI-H2 kuvame ukubiza kakhulu ngenxa yezinqubo eziyinkimbinkimbi zokukhiqiza ezithintekayo. Lezi zindleko eziphakeme zingaba isithiyo esikhulu ekutholweni okuphezulu kakhulu.
3. Izinga lokuzikhulula: Amabhethri we-NI-H2 anezilinganiso eziphakeme zokuzikhulula uma kuqhathaniswa namabhethri e-Li-Ion, okungaholela ekulahlekelweni kwamandla okusheshayo lapho kungasebenzi.

Amabhethri e-Lithium-Ion: Ukubuka konke

Amabhethri e-Lithium-ion asephenduke ubuchwepheshe obuqavile be-elekthronikhi ephathekayo, izimoto zikagesi, nokugcinwa kwamandla okuvuselelekayo. Ukwakheka kwabo kufaka phakathi izinto ze-cathode ehlukahlukene, nge-lithium cobalt oxide kanye ne-lithium iron phosphate ibe yiyona evame kakhulu.

Izinzuzo zamabhethri e-lithium-ion

1. Ubuningi Bamandla Abaphezulu: Amabhethri e-Li-Ion ahlinzeka ngomunye wemisebenzi yamandla ephezulu kakhulu kubuchwepheshe bebhethri yamanje, okwenza balungele izinhlelo zokusebenza lapho isikhala nesisindo sibucayi.
2. Ukutholwa okubanzi kanye nengqalasizinda: Ukusetshenziswa okubanzi kwamabhethri e-Li-Ion kuholele ekunikezelweni kwamaketanga okunikeza kanye nezomnotho zesilinganiso, ukunciphisa izindleko kanye nokwenza ngcono ubuchwepheshe ngokuqamba okuqhubekayo.
3. Izinga lokuzikhulula eliphansi: Amabhethri e-Li-Ion ngokuvamile anezinga eliphansi lokuzikhulula, okuvumela ukuthi agcine imali ekhokhwayo isikhathi eside uma ingasebenzi.

Okubi kwamabhethri e-lithium-ion

1. Ukukhathazeka Ngokuphepha: Amabhethri e-Li-Ion atholakala ekubalekeni okushisayo, okuholela ekutheni kube nokushisa ngokweqile nangomlilo ongaba khona. Ukuba khona kwama-electrolyte avuthayo kuphakamisa ukukhathazeka ngokuphepha, ikakhulukazi kuzinhlelo zokusebenza ezinamandla kakhulu.
2. Impilo yomjikelezo ekhawulelwe: Ngenkathi uthuthuka, impilo yomjikelezo yamabhethri e-li-ion ngokuvamile imfushane kunaleyo yamabhethri we-NI-H2, adinga ukushintshwa njalo.
3. Izinkinga Zemvelo: Ukukhishwa nokucutshungulwa kwe-lithium ne-cobalt kuphakamisa ukukhathazeka okukhulu kwemvelo nokuziphatha okuhle, okubandakanya ukubhujiswa kwendawo kanye nokwephulwa kwamalungelo abantu ekusebenzeni kwezimayini.

Ukugcina

Kokubili amabhethri we-nickel-hydrogen kanye nama-lithium-ion aveza izinzuzo ezihlukile nobubi okumele kubhekwe lapho kuhlaziywa ukufaneleka kwabo kwezicelo ezahlukahlukene. Amabhethri we-nickel-hydrogen anikeza isikhathi eside, ukuphepha, kanye nezinzuzo zemvelo, ukuzenza elungele ukusetshenziswa okukhethekile, ikakhulukazi e-aerospace. Ngokuphambene, amabhethri e-lithium-ion agqamile ku-energy density kanye nesicelo esisakazekile, ukuzenza ukukhetha okuthandwayo kwe-elekthronikhi yabathengi nezimoto zikagesi.

Njengoba isimo samandla semvelo siyaqhubeka nokuvela, ukucwaninga okuqhubekayo kanye nentuthuko kungaholela kubuchwepheshe bebhethri obuthuthukisiwe obuhlanganisa amakhono womabili amasistimu ngenkathi egqugquzela ubuthakathaka babo. Ikusasa lesitoreji samandla cishe lizongena ngendlela ehlukahlukene, lifaka izici ezihlukile zobuchwepheshe bebhethri ngalinye ukuze bahlangabezane nezidingo zohlelo lwamandla esimeme.
