Ngesidingo somhlaba samandla amasha, amandla amasha asephenduke amandla ajwayelekile esikhathi esizayo kancane kancane, kanye namandla ajwayelekile aseChina esikhathini esizayo.Ngokuthuthukiswa kwesayensi nobuchwepheshe e-China, ibhethri ye-lithium, njengamandla amasha, isondele ekuphileni kwansuku zonke kwabantu kancane kancane futhi isetshenziswe kabanzi futhi kabanzi.Ngokuzayo, izothatha indawo kawoyela futhi ibe negalelo elikhulu ekuthuthukisweni okusimeme nokuvikelwa kwemvelo komhlaba.Okulandelayo, senza isingeniso mayelana nomkhiqizo wethu— ibhethri le-lithium ongakwazi okwengeziwe ngemikhiqizo yethu.
Amaseli ethu ahlinzekwa ikakhulukazi ngabakwa-SAMSUNG, LG, LISHEN nezinye izinhlobo zemikhiqizo eyaziwa kakhulu, ngakho-ke, imikhiqizo yethu enekhwalithi ephezulu futhi ephephile.Amaseli ethu ikakhulukazi ahlanganisa i-3.85V high pressure lithium cobalt cell, 3.7V lithium cobalt cell, 3.63V ternary lithium cell, 3.2V lithium iron phosphate cell.Izimo zabo ziyi-cylindrical, isikwele kanye nezinga lokushisa elingavamile futhi elisebenzayo ekushiseni okujwayelekile -20 ~ 65 ℃, izinga lokushisa eliphezulu -20 ~ 80 ℃, izinga lokushisa eliphansi -40 ~ 65 ℃ kanye nezinga lokushisa elibanzi -40 ~ 80 ℃.
Kukhona ukusetshenziswa okuthathu kwebhethri ye-lithium: izimoto zamandla amasha, ukugcinwa kwamandla kanye nogesi wabathengi.Inkampani yethu ayikhiqizi ibhethri ye-lithium yemoto entsha yamandla, kodwa singakhiqiza ibhethri ye-lithium ukuze isetshenziswe okunye.Ngaphezu kwemikhiqizo yethu yebhethri ye-lithium ekhona, onjiniyela bethu bangaklama ibhethri ngokuya ngezidingo noma izidingo zamakhasimende ethu.Kukhona umehluko phakathi kwebhethri ye-lithium.Okulandelayo ukuhlukaniswa okuningiliziwe.

I-Lithium cobaltate iyisizukulwane sokuqala sezinto ezithengiswayo ze-cathode, eziye zashintshwa kancane kancane futhi zathuthukiswa emashumini eminyaka entuthuko.Kungabhekwa njengento evuthiwe kakhulu ye-cathode yebhethri ye-lithium ion.I-Lithium cobalt oxide inezinzuzo zesikhulumi sokukhipha okuphezulu, umthamo othize ophezulu, ukusebenza kahle kwamabhayisikili, inqubo elula yokuhlanganisa nokunye.I-lithium cobalt oxide inendawo ebhethrini elincane, lapho ukuminyana ngobuningi kubaluleke kakhulu.I-Lithium cobaltate iseyisinqumo esingcono kakhulu sebhethri elincane le-lithium.
I-Lithium iron phosphate ingenye yezinto ze-cathode eziheha ukunaka okubanzi njengamanje.Izici zayo eziyinhloko azinazo izinto eziyingozi, izindleko eziphansi, ukuphepha okuhle, nempilo yomjikelezo kufika izikhathi ezingu-10,000.Lezi zici zenza izinto ze-lithium iron phosphate ngokushesha zibe indawo yokucwaninga, futhi ibhethri ye-lithium iron phosphate isetshenziswe kabanzi emkhakheni wezimoto zikagesi.
I-Ternary impahla yigama elivamile le-lithium nickel cobalt manganese oxide enesakhiwo esifana kakhulu ne-lithium cobalt acid.Lokhu kwaziswa kungalinganiswa futhi kulawulwe ngokwamandla athile, ukugaywa kabusha, ukuphepha kanye nezindleko.Ukwenyuka kokuqukethwe kwe-nickel kuzokhuphula umthamo wezinto ezibonakalayo, kodwa kuzokwenza ukusebenza komjikelezo kube kubi kakhulu.Ukuba khona kwe-cobalt kungenza isakhiwo sezinto sizinze, kodwa okuqukethwe okuphezulu kuzonciphisa umthamo.Ukuba khona kwe-manganese kunganciphisa izindleko futhi kuthuthukise ukusebenza kokuphepha, kodwa okuqukethwe okuphezulu kuzobhubhisa isakhiwo esinengqimba sento.Ngakho-ke, kuwukugxilwa kocwaningo lwe-ternary material kanye nokuthuthukiswa ukuthola ubudlelwano obulinganayo phakathi kwezinto ezintathu ukuze kuthuthukiswe ukusebenza okuphelele.
Ngokuvamile, i-lithium cobalt acid ifanele ibhethri elincane le-lithium, ibhethri ye-lithium iron phosphate iphephile, impilo ende, ukumelana nokushisa okuphezulu.Ibhethri ye-Ternary lithium inesisindo esincane, iphezulu ekusebenzeni kahle kokushaja, ukumelana nokushisa okuphansi, ngakho-ke bonke banezici zabo.
Imikhiqizo yethu ihlukaniswe yaba izindawo zokusebenza: ibhethri yokugcina amandla, ibhethri lamandla kanye nebhethri yomthengi.
Isakhiwo sonke sebhethri ye-lithium siyefana, njengoba kuboniswe esithombeni esingezansi.Yakhiwe izingxenye ezine: izinto ezibonakalayo ze-electrode, impahla ye-electrode engalungile, i-diaphragm ne-electrolyte.Umehluko ubonakala ikakhulukazi ekusebenzeni.
Amabhethri e-lithium-ion asetshenziswa kakhulu kumaselula, amakhompyutha aphathwayo, amakhamera edijithali, amakhamera edijithali, izinsiza zamandla eselula, amathoyizi kagesi neminye imikhiqizo kagesi yabathengi, okuyilokho okubizwa ngokuthi "imikhiqizo ye-3C" amaseli ebhethri e-lithium namamojula, okuyinhloko. ifomu ihlukaniswe cylindrical, isikwele kanye soft pack ibhethri.Ngenxa yesidingo sevolumu ephezulu yebhethri ye-lithium yabathengi, ukuminyana kwamandla kuphezulu, i-lithium cobalt oxide nezinto ze-ternary njenge-electrode eqondile.
Ibhethri lamandla nebhethri yokulondoloza amandla nakho kunezidingo ezihlukene zokuminyana kwamandla nezinye izici.Njengamanje, i-lithium iron phosphate ne-ternary lithium ibhethri isetshenziswa kubhethri lamandla nebhethri yokugcina amandla.

Imikhiqizo yethu ihlukaniswe yaba ibhethri ye-aluminium igobolondo le-lithium, ibhethri ye-lithium yensimbi kanye nebhethri ye-lithium ethambile ngezinto zokupakisha zangaphandle.
Njengoba ibhethri ye-lithium yephakethe elithambile lisebenzisa ukupakishwa kwefilimu ye-aluminium-plastic, ibhethri ye-lithium yephekhi elithambile ngokuvamile ngeke liqhume ezimeni zezingozi zokuphepha, kuphela amaqhuqhuva noma ukuqhekeka.Cishe u-20% ulula kunebhethri yegobolondo le-aluminium, futhi cishe u-5 ~ 10% umthamo ophakeme kunebhethri yegobolondo le-aluminium.Ngaphezu kwalokho, ibhethri ye-lithium yepakethe ethambile inokumelana okuphansi kwangaphakathi nempilo yomjikelezo omude, ifaneleka kakhulu ukuphatheka, idinga indawo ephezulu noma izinhlelo zokusebenza eziwugqinsi, njenge-3C umthengi kagesi.
Ibhethri ye-Aluminium shell lithium inamandla athile aphezulu, i-modulus ethize, ukuqina kokuphuka, amandla okukhathala kanye nokuzinza kokumelana nokugqwala.I-aluminium ingxubevange izici eziphansi zokuminyana, okungezona uzibuthe, ingxubevange ezinzile ekushiseni okuphansi kunokumelana nozibuthe kuncane, ukuminyana komoya okuhle kanye nemisebe eyenziwe ibola ngokushesha, ngakho-ke isetshenziswe kabanzi kwezokundiza, i-aerospace, izitimela ezinesivinini esikhulu, ukukhiqiza imishini, ezokuthutha kanye nemboni yamakhemikhali.
Ukuzinza komzimba nokumelana nokucindezela kwebhethri ye-lithium yensimbi kuphakeme kakhulu kunebhethri le-aluminium shell material.Ngemuva kokuthi abaklami benkampani yethu baklame isakhiwo esilungiselelwe, idivayisi yokuphepha ibekwe ngaphakathi kwebhethri yangaphakathi, futhi ukuphepha kwebhethri yekholomu yensimbi ye-lithium sekufinyelele ukuphakama okusha.
Ngemuva kwesingeniso esingenhla, kufanele ube nokuqonda okujulile kwebhethri yethu ye-lithium.Lindela ukuthi usithinte ngokushesha ngangokunokwenzeka, sisebenzisa amandla nesenzo ukukutshela ukuthi sithembekile, imikhiqizo yethu namasevisi azokwenza waneliseke kakhulu.Bheka phambili ukubambisana nawe, ngiyabonga!
