Njengenxalenye ebalulekileyo yezithuthi zombane, i-lithium-i-IIIum-ion iya kuba nefuthe lemo lokusingqongileyo ngexesha lesigaba sokusetyenziswa. Ngohlalutyo lwempembelelo okusingqongileyo engqongileyo, iipakethi zebhetri ze-lithium-ion, eziqulathe izixhobo ezahlukeneyo ezili-11, zazikhethwe njengento yokufunda. Ngokuphumeza indlela yovavanyo lomjikelo wobomi kunye nendlela yokungena kwi-Engdopy yokulinganisa umthwalo wokusingqongileyo, inkqubo yovavanyo lwamanqanaba amanqanaba amaninzi esekwe kwiimpawu zebhetri yendalo esingqongileyo.
Uphuhliso olukhawulezileyo lweshishini lezothutho1 ludlala indima ebaluleke kakhulu kuphuhliso lwezoqoqosho kunye noluntu. Kwangelo xesha, ikwasebenzisa inani elikhulu le-fossil fuels, ebangela ukungcoliseka kwendalo esingqongileyo. Ngokwe-IEA (ka-2019), malunga nesithathu sokukhutshwa kwe-CO2 ye-CO2 kwicandelo lezothutho. Ukwenzela ukunciphisa imfuno yamandla amakhulu kunye nomthwalo omkhulu wokusingqongileyo kumzi mveliso wezothutho lwehlabathi, uphawu lokufakelwa kweshishini luthathwa njengenye yamanyathelo aphambili ukunciphisa ukukhutshwa okungcolileyo. Ngenxa yoko, ukuphuculwa kwezithuthi ezinobuhlobo kunye nokusindisa, ngakumbi izithuthi zombane (ii-EVs), kuye kwakho ukhetho oluthembisayo kwishishini lemoto.
Ukuqala ukusuka kwisicwangciso seminyaka emihlanu yeminyaka emihlanu (2010 ukuya ku-2000), urhulumente waseTshayina uthathe isigqibo sokukhuthaza ukusetyenziswa kwezithuthi zombane ukuze enze isicoci sokuhamba. Nangona kunjalo, ingxaki eqatha yezoqoqosho inamazwe anyanzelekileyo ukuba ajamelane neengxaki ezinjengeentlekele zamandla, ukunyuka kwamaxabiso e-fossil, ukungasebenzi kakuhle, ubuchule bobuchule bokwenzela abantu kunye nokwenza izigqibo kubathengi. Yiyo loo nto, ukwamkelwa okuphantsi kunye nokwamkelwa kwezithuthi zombane nokuthintela ukwamkelwa kwangoko kwezithuthi zombane kwintengiso.
Ngokuchasene noko, ukuthengisa izithuthi eziqhutywa ngamafutha aqhubekayo ukwehla, kunye nenqanaba lokukhula kwinani labanini bancipha. Ngamanye amagama, ngokunyanzeliswa kwemigaqo kunye nokuvuswa kokuqonda kwendalo, ukuthengisa kwezithuthi zepetroli kutshintshile ngokubhekisele kwintengiso yezithuthi zombane, kwaye izinga lokungena liyanda ngokukhawuleza. Okwangoku, iibhetri ze-lithium-ion) lolona khetho lubalaseleyo kwicandelo lezithuthi zombane ngenxa yobunzima bendlela yabo, ukusebenza kakuhle, ukungcungcutheka kwamandla aphezulu kunye nemveliso ephezulu yamandla. Ukongeza, iibhetri ze-lithium-ion, njengetekhnoloji ephambili kwiinkqubo zokugcina ibhetri, zikwanokuba namandla amakhulu ophuhliso lwamandla kunye nokuncitshiswa kwekhabhoni.
Kwinkqubo yokukhuthaza, iimoto zombane zijongwa njengezithuthi ezikhutshwayo zeZero, kodwa ukuvelisa kunye nokusetyenziswa kweebhetri zabo kunefuthe elikhulu kwindalo esingqongileyo. Ngenxa yoko, uphando lwakutshanje lujolise ngaphezulu kwezibonelelo zendalo esingqongileyo. Kukho uphando oluninzi malunga namanqanaba amathathu emveliso, ukusetyenziswa nokulahlwa kwezithuthi zombane, kuthathe isithathu seyona ndawo isetyenziswayo ye-lithim ye-phosphate ye-phosphate ye-phosphate (i-LFP) yemakethi yemoto yaseTshayina njengesifundo esikhethekileyo. Kwezi Beterries ezintathu ezisekwe kuvavanyo lomjikelo wobomi (i-LCA) yamanqanaba emveliso, ukusetyenziswa kunye nokurisayikilisha iibhetri. Iziphumo zibonisa ukuba ibhetri ye-litlium ye-phosphate inentsebenzo engcono yokusingqongileyo kunebhetri kathathu kwiimeko eziqhelekileyo, kodwa ukusebenza kwamandla kwiSigaba sokuSebenzisa akulunganga njengexabiso lokuphinda lisebenze.
