I- "Lithium Battery" uhlobo lwebhethri elenziwe nge-lithium Metal noma i-Lithium Alloy njengezinto ezingezinhle ze-elektrodi futhi isebenzisa isixazululo se-electrodete esingalungile. Amabhethri e-Lithium Metal ahlongozwa okokuqala futhi afundwe nguGilbertn.lewis ngo-1912. Ngawo-1970, i-ntswittham ihlongoze futhi yaqala ukutadisha amabhethri e-lithium-ion. Ngenxa yezakhiwo zamakhemikhali ezisebenzayo ze-lithium Metal, ukucubungula, ukulondolozwa kanye nokusetshenziswa kwe-lithium Metal kudinga izidingo eziphakeme kakhulu zemvelo. Ngakho-ke, ibhethri le-lithium alisetshenziswanga isikhathi eside. Ngokuthuthukiswa kwesayensi nobuchwepheshe, ibhethri le-lithium liye laba yimigwaqo.
Amabhethri e-Lithium angahlukaniswa ngezigaba ezimbili: amabhethri e-lithium Metal nama-Lithium Ion. Amabhethri e-Lithium-Ion awaqukethe i-lithium yensimbi futhi ayaphindeka. I-Lithium Metal Battery, isizukulwane sesihlanu sebhethri elivuselelwa kabusha, lazalwa ngo-1996. Ukuphepha kwalo, umthamo othize, izinga lokuzikhandla kanye nesilinganiso sentengo yokusebenza kungcono kunebhethri le-lithium-ion. Ngenxa yezidingo zabo zobuchwepheshe obuphakeme, izinkampani ezimbalwa kuphela emazweni ambalwa manje ezikhiqiza ibhethri lensimbi ye-lithium-yensimbi.
Impilo yebhethri
Amabhethri e-Lithium Ion angakhokhiswa kuphela futhi akhiphe izikhathi ezingama-500?
Ngikholwa ukuthi iningi labathengi lizwile ukuthi impilo yamabhethri e-lithium "izikhathi ezingama-500", izikhathi ezingama-500 zokukhokhiswa nokukhipha, ibhethri lizokufa ". Ukuze wembule impilo yebhethri, abangane abaningi bashaja isikhathi ngasinye lapho ibhethri likhathele ngokuphelele. Ingabe lokhu kwandise ngempela impilo yebhethri? Impendulo ithi cha. Impilo yebhethri le-lithium "izikhathi ezingama-500", ezibhekise kwinani lamacala, kodwa kumjikelezo wokushaja.
Umjikelezo wokushaja usho ukuthi inqubo yokukhokhisa yonke ibhethri kusuka ngokugcwele ngaphandle kokungenalutho bese kuthi ngaphandle kokungenalutho kugcwele akufani nokushaja kanye. Isibonelo, ucezu lukagesi we-lithium lusebenzisa uhhafu wogesi ngosuku lokuqala, bese ulugcwalisa ngogesi. Uma lokhu kunjalo ngosuku olulandelayo, luzokhokhiswa ngesigamu futhi lukhokhiswa kabili kukho konke, olungabalwa kuphela njengomjikelezo owodwa wokushaja, hhayi amabili. Ngenxa yalokho, kungavame ukuthatha amacala ambalwa ukuqedela umjikelezo. Ngomjikelezo ngamunye wokushaja, umthamo webhethri uncishisiwe kancane. Kodwa-ke, lokhu kuncishiswa kwamandla kuncane kakhulu, amabhethri asezingeni eliphakeme ngemuva kwemijikelezo eminingi, asazogcina ama-80% omandla okuqala, imikhiqizo eminingi ye-lithium-aniwe asazosetshenziswa njengenjwayelo ngemuva kweminyaka emibili noma emithathu. Kuyiqiniso, impilo ye-lithium isadinga ukushintshwa ngemuva kokuphela kwempilo.
Futhi okubizwa ngokuthi amahlandla angama-500, kubhekiselwa kumenzi ekujuleni kokufihla okungapheli (okufana nama-80%) ukufezekisa izikhathi ezingama-625 eziguqukayo, kuze kufike ku-500 imijikelezo yokushaja.
(80% ≤ 625 ≤ 500) (Ukunganaki izinto ezinjengamandla ancishisiwe amabhethri e-lithium)
Kodwa-ke, ngenxa yemiphumela ehlukahlukene yempilo yangempela, ikakhulukazi ukujula kokukhishwa akuhlangene, ngakho-ke "umjikelezo wokushaja we-500" ungasetshenziswa kuphela njengempilo yebhethri ebhekisisa.
Kulungile ukusho ukuthi impilo ye-lithium ihlobene nenani lezikhathi zokukhokhisa, kepha hhayi ngokuqondile nenani lamacala.
Mane nje uqonde, ngokwesibonelo, ukuthi ucezu lukagesi we-lithium lusebenzisa uhhafu kagesi ngosuku lokuqala, bese ulugcwalisa ngogesi. Uma lokhu kunjalo ngosuku olulandelayo, luzokhokhiswa ngesigamu futhi lukhokhiswa kabili kukho konke, olungabalwa kuphela njengomjikelezo owodwa wokushaja, hhayi amabili. Ngenxa yalokho, kungavame ukuthatha amacala ambalwa ukuqedela umjikelezo. Ngomjikelezo ngamunye wokushaja, inani likagesi lincishiswa kancane. Kodwa-ke, ukuncishiswa kuncane kakhulu. Amabhethri asezingeni eliphakeme asazogcina ama-80% kagesi wawo wokuqala ngemuva kwemijikelezo eminingi. Kungakho mikhiqizo eminingi enamandla ye-lithium-avered isazosetshenziswa njengenjwayelo ngemuva kweminyaka emibili noma emithathu. Kuyiqiniso, impilo ye-lithium idinga ukushintshwa ekugcineni kosuku.
Impilo yempilo kagesi we-lithium ngokuvamile i-300 × 500 ishaja imijikelezo. Ukucabanga ukuthi inani likagesi elinikezwe yi-stud ephelele ngu-q, uma ukuncishiswa kukagesi ngemuva kokuthi umjikelezo ngamunye wokushaja awunakwa, ugesi we-lithium unganikeza noma ungeze amandla angu-300Q-500Q ngenani lempilo yawo. Kulokhu, siyazi ukuthi uma usebenzisa i-1/2 ngasikhathi, ungashaja izikhathi ezingama-600-1000; Uma usebenzisa i-1/3 ngasikhathi, ungashaja izikhathi ezingama-900. Futhi njalo, uma ukhokha ngokungahleliwe, inani lezikhathi aliqinisekile. Ngamafuphi, akunandaba ukuthi kukhishwe malini, inani eliphelele likagesi elingezwe ku-300Q ~ 500Q lihlala likhona. Ngakho-ke, futhi singaqonda ukuthi impilo yebhethri le-lithium ihlobene nemali ekhokhwayo yebhethri, kepha hhayi inani lamacala. Awukho umehluko obalulekile phakathi kokukhipha okujulile nokungeniswa okungajulile empilweni ye-lithium.
Eqinisweni, ukushaja okungajulile kuzuzisa kakhulu kugesi we-lithium, kuphela lapho imodyuli yamandla yomkhiqizo isesikhathini sikagesi we-lithium, kunesidingo sokushaja okujulile. Ngakho-ke, ukusetshenziswa kwemikhiqizo yamandla e-lithium amandla okunikelwa akudingeki ukuthi anamathele kwinqubo, konke ukwenza lula kuqala, ukushaja nganoma yisiphi isikhathi, akudingeki ukhathazeke ngokungathinta izinga lokushisa elicacisiwe, okungukuthi , Bangaphezu kwama-35 ° C, Ibhethri lizoqhubeka nokunciphisa amandla alo okunikezwa amandla, okungukuthi, ibhethri ngeke linikezwe isikhathi eside njengenjwayelo. Uma idivaysi ikhokhiswa kulokhu kushisa, ukulimala kwebhethri kuzoba kukhulu kakhulu. Noma ibhethri ligcinwa endaweni eshisayo, lizodala ukulimala okuhambisanayo kwekhwalithi yebhethri. Ngakho-ke, kuyindlela enhle yokwelula impilo ye-lithium ngangokunokwenzeka ukuyigcina ekushiseni okusebenzayo okuzuzisayo.
Uma ugesi we-lithium usetshenziswa endaweni yokushisa ephansi, okungukuthi, ngaphansi kwe-4 ° C, kuzotholakala nokuthi impilo yebhethri incishisiwe, futhi ugesi wokuqala we-lithium wezingcingo ezithile eziphathwayo angeke akhokhiswe ngamazinga okushisa aphansi. Kepha ungakhathazeki kakhulu, lesi yisimo sesikhashana kuphela, ngokungafani nokusetshenziswa kwendawo yokushisa ephezulu, uma izinga lokushisa likhuphuka, ama-molecule ebhethri ayavutha, abuyele kugesi owedlule.
Ukwandisa ukusebenza kahle kwamabhethri e-lithium-ion, kudinga ukusetshenziselwa njalo ukuvikela ama-elektroni kumabhethri e-lithium ageleza ngaso sonke isikhathi. Uma ugesi we-lithium awusetshenziswa kaningi, sicela ukhumbule ukuqeda umjikelezo wokushaja ngogesi we-lithium njalo ngenyanga, futhi wenze ukulinganiswa kukagesi kanye, okungukukhipha okujulile.
Ukuhunyushwa kwezinhlinzeko zeZinga Likazwelonke:
a. Le ncazelo icacisa ukuthi ukuhlolwa kwempilo yomjikelezo kwenziwa ngendlela ejulile nejulile.
b. Ngokusho kwale modeli, impilo yomjikelezo ye-Lithium Battery isengaphezu kwama-60% ngemuva kwemijikelezo engu-300.
Kodwa-ke, inani lemijikelezo etholwe yizinhlelo ezihlukile zomjikelezo ihluke kakhulu, ngokwesibonelo, lezinye izimo ezingenhla zihlala zingashintshiwe, kuguqula kuphela i-voltage voltage ye-voltage ye-voltage ye-4.1 volt ye-voltage yempilo efanayo Uhlobo lwebhethri, ukuze ibhethri aluseyona imodi yokushaja ejulile, futhi inani lempilo yomjikelezo lingandiswa cishe ngo-60%. Ngemuva kwalokho uma i-cutoff voltage inyuke ibe ngu-3.9v ukuze ihlolwe, inani lemijikelezo kufanele lenyuswe amahlandla ambalwa.
Lesi sitatimende sokushaja kwe-cyclic kanye nokukhishwa singaphansi kwempilo eyodwa, kufanele siqaphele ukuthi incazelo ye-lithium yebhethri yokushaja umjikelezo: Umjikelezo wokushaja ubhekisa ebhethri le-lithium kusuka ku-angeli lutho, bese kuthi kusuka kungenalutho kwinqubo ephelele. Futhi lokho akufani nokushaja kanye. Ngaphezu kwalokho, lapho ukhuluma ngenombolo yemijikelezo, awukwazi ukungazinaki imibandela yomjikelezo. Akukwenzi mqondo ukubeka eceleni imithetho yokukhuluma ngenombolo yemijikelezo, ngoba inani lemijikelezo liyindlela yokuhlola impilo yebhethri, hhayi isiphetho!
