Umlando wamabhethri e-lithium-particle ka-18650 waqala ngawo-1970 lapho owokuqala ngqa.18650 ibhethriyakhiwe umhlaziyi we-Exxon ogama lakhe linguMichael Stanley Whittingham. Umsebenzi wakhe wokwenza ukuguqulwa okuyinhloko kwe-ibhethri ye-lithium ionfaka egiyeni eliphezulu iminyaka eminingi ukuhlolwa okwengeziwe ukuze kucolise ibhethri ukuze isebenze kahle futhi ivikeleke ngendlela obekungalindeleka ngayo. Khona-ke, ngaleso sikhathi, ngo-1991, iqembu lochwepheshe nabacwaningi okuthiwa u-John Goodenough, u-Rachid Yazami, no-Akira Yoshino babambisana ukuze bakhe futhi balethe ukuze kuboniswe i-lithium particle cell. Amaseli ebhethri ezinhlayiyana ze-lithium okuqala akhiqizwa kahle futhi athengiswa ngabakwaSony. (Neverman et al., 2020) Kusukela lapho, izinguquko kanye nokuthuthukiswa kwenziwe ukuze kwandiswe umphumela neminyaka yokuphila yebhethri le-18650. Konke kwalokhu kuqhubekela phambili kuletha ibhethri elisebenza kangcono futhi ngaleyo ndlela, ukuduma okwengeziwe kokusetshenziswa kwazo kanye nezinhlelo zokusebenza lapho ubheka. Namuhla, amabhethri e-lithium-particle abusa ibhizinisi lebhethri futhi atholakala yonke indawo ezintweni eziningi zomndeni esizisebenzisa njalo. Kunethuba elihle lokuba ngumnikazi wezinto eziningi ezilawulwa yi18650 amabhethri, kungakhathaliseki ukuthi uyakuqonda yini. Kusukela ngo-2011, amabhethri e-lithium-particle amelela u-66% wawo wonke amadili ebhethri asebenza ngebhethri alungile.
Ibhethri le-18650 ibhethri le-lithium-particle. Igama livela ezilinganisweni ezithile zebhethri: 18mm x 65mm. Ibhethri ye-18650 ine-voltage engu-3.6v futhi inendawo ethile ku-2600mAh kanye ne-3500mAh (mili-amp-amahora). (Osborne, 2019) Lawa mabhethri asetshenziswa ekukhanyeni, ezindaweni zokusebenza, ezingxenyeni zehadiwe futhi, ngokumangazayo, izimoto zikagesi ezimbalwa ngenxa yokwethembeka kwazo, isikhathi eside, namandla azophinda anikezwe amandla izikhathi eziningi. Amabhethri angu-18650 azobhekwa “njengebhethri yesiteshi esiphezulu.” Lokhu kusho ukuthi ibhethri ihloselwe ukukhiqiza amandla aphezulu we-voltage kanye nesimanje ukufeza izidingo zamandla zegajethi ehlangene esetshenziswa kuyo. Ngakho-ke kungani lawa mabhethri amancane aqinile esetshenziswa ezintweni eziyinkimbinkimbi, ezilangazelele ihadiwe yamandla edinga izinga eliqinile, elibalulekile lamandla okusebenza. Ngaphezu kwalokho, inobukhulu obuphezulu bokukhishwa, okusho ukuthi ibhethri lingancipha kuze kufike ku-0% ngaphandle kokuthi yonke into inamandla okunika amandla ibhethri ngokuphelele. Noma kunjalo, lokhu akuwona umkhuba ophakanyisiwe, njengoba isikhathi esengeziwe sizokwenza ukudonsa isikhathi eside kulimaza ibhethri futhi kuthinte ukwethulwa kwayo okuvamile.
Izindleko zebhethri le-18650 zingasebenza kabanzi ngokuya ngohlobo, usayizi wenqwaba kanye nokuthi ibhethri elivikelwe noma elingavikelekile. Isibonelo, ibhethri le-Fenix 18650 lingahamba ngenani lisuka ku-$9.95 liye ku-$22.95 (lawa mabhethri abiza kancane kunemikhiqizo eminingi ehlukene kuyilapho ucabangela imikhawulo), kuya ezinhlobonhlobo zebhethri ozifunayo. Lawa mabhethri anembobo yokushaja ye-USB khona kanye ebhethrini langempela, okwenza ukunika amandla kabusha kube lula. Zisezingeni lezindleko ezinkulu kunabanye njengoba zisetshenzwa ngempilo kahle njengento yokuqala ekhathazayo, ziqhayisa ngamasethi amathathu esiqinisekiso sokushisa ngokweqile ukuze ugweme ukujikeleza okufushane ukuze ukwazi ukuthola imijikelezo yokushaja efika ku-500 ebhethrini eliwudwa ngaphandle kwesizathu sokucindezeleka phezu kokuqhuma. noma ukukhishwa ngokweqile. Amabhethri ambalwa angavikelekile atholakalayo angatholakala ngezindleko ezingabizi kakhulu, kodwa ngokufanayo nanoma yini oyithengayo kuwebhu, kubalulekile ukufakazela okwengeziwe ekukhetheni kwakho ukuthenga kunezindleko nje.
Kusetshenziswe amabhethri e-Lithium Particle angu-18650
Amabhethri ezinhlayiyana ze-Lithium angu-18650 asetshenziswa ngendlela emangalisayo asetshenziswa njengezindawo ezishisayo zamagajethi alula ngenxa yomklamo ojwayelekile kanye nezindleko zokuhlanganisa ezisebenzayo. IBusiness 18650 cell iza ngezinhlelo ezihlukene ngenxa yokwenziwa kwamagajethi ezokuphepha ahlukahlukene. Ukungena kwamanje kugajethi kanye ne-top vent kuyadingeka amagajethi omshwalense wawo wonke amabhethri e-Li-particle 18650 ebhizinisi. Ngokuphambene, i-coefficient thermistor ephozithivu yezinga lokushisa, i-base vent, kanye nesekethe yokuvikela amagajethi omshwalense okuzikhethela angethulwa, ethulwe ngokuzimela, noma ahlanganiswe kumabhethri ebhizinisi angu-18650. Ibhizinisi lama-ejenti amane amabhethri e-Li-particle angu-18650 ahlakazwa futhi abhekwa ngokufana nokungafani kwamagajethi wokuqinisekisa.
Umthombo Omuhle Wamabhethri Asetshenzisiwe angu-18650 Lithium Particle
Ukuze ube nomthombo ohloniphekile wamabhethri akho ezinhlayiyana ze-18650 ze-lithium kufanele ulande umkhiqizo we-IMAX B6 yeshaja yebhethri/isihlazi sokushaja. Izokuvumela ukuthi ushaje futhi uhlole amabhethri ngaphambi kokufudumala ucabange ukuthi uwashaja ngaphezu kuka-4.0. Okubi okuyinhloko kwalo mthombo ukuthi awukwazi ukushintsha i-voltage yephethini ekhawulela ngendlela engavamile, nokho enakho isikrini senzwa yezinga lokushisa esimisa ishaja kucatshangwa ukuthi izinga lokushisa lidlula izinga lokushisa olisethile.
Ungawathola kanjani amabhethri ashibhile angu-18650?
Amaseli asekelwe ku-lithium yiwona athambekele kakhulu ekuphoxekeni kwangaphakathi okushaqisayo. Akuphakanyiswa ukuthi ubheke imithombo eshibhile, ngaphandle uma udinga nje umbhangqwana ekukhanyeni. Ukuthembela esihlokweni kwelinye ibhizinisi kuwukucela nje ukuphazamiseka. I-Panasonic inesikhathi esingcono kakhulu sokuphila kanye nerekhodi lokuphepha lalolu hlobo lweseli. Chitha okwengeziwe. Kubiza kancane kunokushisa ikhaya lakho noma imoto yakho. Uma ucabanga ukuthi ufuna ukwakha uchungechunge lwamaseli, ungalokothi usebenzise i-weld. Amaseli agxilile embonini ane-welded ngamabala ngakho ukushisa kukhawulelwe kakhulu futhi kusatshalaliswa ngokushesha. Kukhona okwamanje izibambi zepulasitiki ezitholakalayo, ngakho-ke ungakwazi ukuhlela lezo njengoba kudingekile futhi ngemva kwalokho ushumeke amaseli. Uma kwenzeka lezi zibambi zingenakwenzeka njengoba udinga ukuphinda ugcwalise iphakethe langaphambilini, usesimweni esihle kakhulu sokulithumela kuchwepheshe oqeqeshwe ngebhethri. Njengoba ngisho ne-NiCd ne-Ni-MH ziza kusici sesakhiwo esingu-16840, ukuthola uhlobo oluthile olungamukeleki ohlelweni lwakho kungaba inhlekelele.
Isiphetho
Amabhethri amaningi angu-18650 anephethini yokuba khona kwansuku zonke cishe kwemijikelezo yokushaja engu-300-500. Isibonelo, amabhethri ajwayelekile ahlolwa emijikelezweni engama-500. Lokhu kusho ukuthi ibhethri empeleni lizofuna ukushaja ngokuphelele into efana no-80% womkhawulo walo oyisisekelo. Uma ifika kulowo mkhawulo, “umjikelezo wempilo” yebhethri ubhekwa njengophelile. Kodwa-ke, kunoma yikuphi, ungathola amashaji amaningi ebhethri, ikhono layo lizokwehla kancane kancane ngokuhamba kwesikhathi.
