Njengenxalenye ebalulekileyo yezithuthi zombane, iibhetri ze-lithium-ion ziya kuba nefuthe elithile lokusingqongileyo ngexesha lesigaba sokusetyenziswa.Uhlalutyo olubanzi lwempembelelo yendalo esingqongileyo, iipakethe zebhetri ze-lithium-ion, ezibandakanya izinto ezi-11 ezahlukeneyo, zikhethwe njengento yokufunda.Ngokuphumeza indlela yokuhlola umjikelezo wobomi kunye nendlela yobunzima be-entropy ukulinganisa umthwalo wokusingqongileyo, inkqubo yokuvavanya isalathisi esinemigangatho emininzi esekelwe kwiimpawu zebhetri yokusingqongileyo iyadalwa.
Uphuhliso olukhawulezayo loshishino lwezothutho1 ludlala indima ebalulekileyo kuphuhliso loqoqosho nentlalo.Kwangaxeshanye, ikwatya isixa esikhulu samafutha efosili, nto leyo ebangela ungcoliseko olukhulu lokusingqongileyo.Ngokutsho kwe-IEA (2019), malunga nesithathu sezinto ezikhutshwayo zeCO2 zehlabathi ziphuma kwicandelo lezothutho.Ukuze kuncitshiswe imfuno enkulu yamandla kunye nomthwalo wokusingqongileyo kushishino lwezothutho lwehlabathi, ukufakelwa kombane kwishishini lezothutho kuthathwa njengelinye lamanyathelo aphambili okunciphisa ukukhutshwa kongcoliseko.Ngaloo ndlela, ukuphuhliswa kwezithuthi ezihambelana nokusingqongileyo kunye nezizinzileyo, ngakumbi izithuthi zombane (EVs), ziye zaba yinto ethembisayo yoshishino lweemoto.
Ukususela kwiSicwangciso seMinyaka emiHlanu ye-12 (2010-2015), urhulumente waseTshayina uthathe isigqibo sokukhuthaza ukusetyenziswa kwezithuthi zombane ukwenza uhambo lucoceke.Nangona kunjalo, ingxaki enkulu yezoqoqosho inyanzelise amazwe ukuba ajongane neengxaki ezifana nengxaki yamandla, ukunyuka kwamaxabiso amafutha e-fossil, ukungabikho kwemisebenzi ephezulu, ukunyuka kwamaxabiso, njl., eziye zachaphazela ingqondo yentlalo, amandla omthengi wabantu kunye nokwenza izigqibo zikarhulumente.Ke, ukwamkelwa okuphantsi kunye nokwamkelwa kwezithuthi zombane kuthintela ukwamkelwa kwangoko kwezithuthi zombane kwimarike.
Ngokuchasene noko, ukuthengiswa kweemoto ezisebenza ngamafutha kwaqhubeka ukuhla, kwaye ukukhula kwenani labanini kwehla.Ngamanye amazwi, ngokunyanzeliswa kwemimiselo kunye nokuvuswa kokuqaphela indalo, ukuthengiswa kweemoto eziqhelekileyo ze-fuel zitshintshile ngokuchasene nokuthengiswa kwezithuthi zombane, kwaye izinga lokungena kwezithuthi zombane likhula ngokukhawuleza.Okwangoku, iibhetri ze-lithium-ion (LIB) yiyona nto ikhethekileyo kwintsimi yezithuthi zombane ngenxa yobunzima bokukhanya, ukusebenza kakuhle, ubuninzi bamandla kunye nokuphuma kwamandla aphezulu.Ukongezelela, iibhetri ze-lithium-ion, njengeteknoloji ephambili yeenkqubo zokugcina ibhetri, nazo zinamandla amakhulu ngokubhekiselele kuphuhliso lwamandla oluzinzileyo kunye nokunciphisa kakhulu ukukhutshwa kwekhabhoni.
Kwinkqubo yokukhuthaza, izithuthi zombane ngamanye amaxesha zijongwa njengezithuthi zero-emission, kodwa ukuveliswa kunye nokusetyenziswa kweebhetri zabo kunempembelelo enkulu kwindalo.Ngenxa yoko, uphando olutshanje lujolise ngakumbi kwiinzuzo zokusingqongileyo zezithuthi zombane.Kukho uphando oluninzi kwizigaba ezithathu zemveliso, ukusetyenziswa kunye nokulahlwa kwezithuthi zombane, kwathatha ezintathu zezona zisetyenziswa kakhulu i-lithium nickel cobalt manganese oxide (NCM) kunye neebhetri ze-lithium iron phosphate (LFP) kwimarike yemoto yombane yaseTshayina njengoko isifundo kwaye wenze uhlalutyo olukhethekileyo.kwezi bhetri zintathu zisekwe kuvavanyo lomjikelo wobomi (LCA) wezigaba zemveliso, ukusetyenziswa kunye nokuhlaziywa kweebhetri zokutsalela.Iziphumo zibonisa ukuba ibhetri ye-lithium iron phosphate inomsebenzi ongcono wokusingqongileyo kunebhetri kathathu kwiimeko eziqhelekileyo, kodwa ukusebenza kakuhle kwamandla kwisigaba sokusetyenziswa akulungile njengebhetri kathathu, kwaye kunexabiso elingaphezulu lokuphinda lisetyenziswe.
