Ukusasazeka okuqhubekayo kweemeko zesicelo kukhuthaze uphuhliso olukhawulezayo lweshishini lebhetri.Nokuba lishishini elitsha elikhulayo lezithuthi zamandla okanye ishishini lokugcina amandla elinyukayo,izixhobo zokugcina amandlalelona khonkco libalulekileyo.Umthombo wamandla ekhemikhali osekelwe kwi-electrochemical oxidation-reduction reaction can avoiding limitation of the Carnot cycle and has an energyconversion effective performance to 80%.Yeyona mveliso yesixhobo ifanelekileyo kwishishini elikhulu lokugcina amandla.Okwangoku, imfuno yokuphucula ukusebenza kwebhetri iyonke iyanda ngokuqhubekayo, kodwa ikwafumana ubunzima obufana nokunciphisa ukusebenza komzimba kunye neekhemikhali, inkqubo kunye nokulungiswa kweendleko.
Amandla emichiza aye afumana inkulungwane yokuqokelela, kwaye inkqubo egqibeleleyo iye yenziwa phantsi kokhokelo lweethiyori zenzululwazi ezisenokuphononongwa.Le nkqubo ibandakanya iindawo ezahlukeneyo zezinto kunye nokuxhasa iinkqubo zokuvelisa ezenza ibhetri.Kwixesha elizayo, kuya kuhlala kukho imeko apho ubugcisa bebhetri obuninzi buqhubeka buhlala kunye, kodwa kuya kubakho okuqhelekileyo kunye nokungaqhelekanga.Ngexesha elifanayo, kuya kubakho iindidi zeemveliso kwinkqubo enye ukuhlangabezana neemfuno ezahlukeneyo ezisezantsi.
Kunzima ukufezekisa ukulungelelaniswa kwemisebenzi emininzi phantsi kwenkqubo yamandla ekhemikhali, kwaye ukuphuculwa komsebenzi omnye kudla ngokufuna umbingelelo womnye umsebenzi.Ke ngoko, ngokusekwe kwimiba etyebileyo yesicelo esezantsi, kugqitywe ekubeni iinkqubo ezahlukeneyo zebhetri ziya kuhlala ixesha elide.Kodwa kufuneka kuqondwe ukuba ukuhlalisana akuthethi ukuba isabelo semarike esiphakathi.
Utshintsho lwentsebenzo luchatshazelwa yimiba emininzi, kwaye ulwalathiso lwempembelelo lunokwahluka.Kubandakanya uhlobo kunye nomlinganiselo wezinto ezintle kunye nezibi, kunye noyilo kunye nenkqubo yokuvelisa, kuya kuchaphazela amandla ombane kunye nokusebenza kwezinga lebhetri, oku kuthetha ukuba ukuba ulwalathiso lwempembelelo luhluke, ukusebenza akuyi kuhambelana.Umzekelo, kwiiibhetri ze-lithium-ion, ifilimu ye-SEI eyenziwe phakathi kwezinto ze-electrode kunye ne-electrolyte kwi-interface e-slid-liquid interface inokuqinisekisa ukufakwa kunye nokukhutshwa kwe-Li + kwaye ngexesha elifanayo i-electron insulate.Nangona kunjalo, njengefilimu ye-passivation, ukusasazwa kwe-Li + kuya kunqunyulwa, kwaye ifilimu ye-SEI iya kuhlaziywa.Iza kubangela ilahleko eqhubekayo ye-Li+ kunye ne-electrolyte, kwaye emva koko inciphise umthamo webhetri.
Imfazwe yezobuchwepheshe kwintsimi yomthamo ophezulu inquma isalathiso sepateni.Imarike yomthamo omkhulu ithetha isabelo esikhulu.Ngoko ke, ukuba uhlobo oluthile lwenkqubo luhlangabezana kangcono neemfuno zemarike yomthamo omkhulu, ukuqaliswa kweemveliso kuya kwandisa kakhulu isabelo senkqubo.Iimfuno ezingqongqo zoxinaniso lwamandla kwiindawo yamandla emotobenze iisistim zebhetri ezinamandla athile aphezulu ukuba zigqame kwaye zibuyisele ezinye iinkqubo.
