Kutshanje, isikhululo samandla sokugcina amandla ebhetri yesodium-ion yokuqala yaseTshayina – iVolin sodium-ion ibhetri yokugcina amandla ebhetri ibekwe eNanning, eGuangxi. Le yinkqubo yesizwe ephambili yophando kunye nenkqubo yophuhliso "i-100 megawatt-yure ye-sodium-ion iteknoloji yokugcina amandla ebhetri ye-sodium-ion" iprojekthi yokubonisa iprojekthi yesigaba sokuqala seprojekthi, ubungakanani obufakelweyo be-2.5 megawatts / 10 megawatt-yure.
Isikhululo sombane sityalwe saza sakhiwa yiNkampani yeGuangxi Power Grid yeSouthern Power Grid, kwaye umlinganiselo wesi sigaba yi-10 MWh. Umlinganiselo opheleleyo weprojekthi uza kufikelela kwi-100 MWh, enokuvelisa i-73 yezigidi zeedigri zombane ococekileyo ngonyaka, Iziko lombane lityalwe kwaye lakhiwe yiNkampani ye-Guangxi Power Grid ye-Southern Power Grid, kwaye isikali sesi sigaba yi-10 MWh. Isikali esipheleleyo seprojekthi siza kufikelela kwi-100 MWh, enokuvelisa i-73 yezigidi zeedigri zombane ococekileyo ngonyaka, ngokuhambelanayo inciphise ukukhutshwa kwekharbon diokside ngeetoni ezingama-50,000, kwaye ihlangabezane neemfuno zombane zabasebenzisi beendawo zokuhlala ezingama-35,000.
Xa kuthelekiswa nokugcinwa kwamandla ebhetri ye-lithium-ion, "abazalwana" ibhetri ye-sodium-ion yokugcina amandla ebhetri egciniweyo, kulula ukuyikhupha, indleko ephantsi, ukusebenza okungcono kumaqondo okushisa aphantsi, kwindawo yokugcina amandla amakhulu kuneenzuzo ezicacileyo. "I-sodium-ion ukugcinwa kwamandla ebhetri kwisikali senqanaba lophuhliso, iindleko zeendleko zingancitshiswa nge-20% ukuya kwi-30%, phantsi kwesiseko sokuphucula ngokupheleleyo ubume bebhetri kunye nenkqubo, ukuphucula izinga lokusetyenziswa kwezinto kunye nobomi bomjikelo, iindleko zombane zinokuphononongwa ukuya kwi-0.2 yuan / kWh, kukukhuthaza ukusetyenziswa koqoqosho kohlobo olutsha logcino," unobhala obalulekileyo we-Chetyn amandla okugcina amandla, isikhokelo sokugcina amandla we-Chetyn kazwelonke. iKomiti yezoBugcisa yoGcino lwaMandla oMbane weSizwe kunye nengcali yesicwangciso-qhinga sobuchwephesha beGridi yaMandla yaseMzantsi, yathi.
Nangona umsebenzi waseTshayina kuphando kunye nophuhliso, ukuveliswa, ukulinganisa, ukukhuthazwa kweemarike kunye nokusetyenziswa kweemveliso zebhetri ye-sodium-ion uguquguquka ngokupheleleyo, akukho mzekelo wamazwe ngamazwe wokusetyenziswa kobuchwepheshe bebhetri ye-sodium-ion kwizikhululo zamandla zokugcina amandla amakhulu.
NgoNovemba ka-2022, i-Guangxi Power Grid Company, ngokubambisana neSouth Grid Energy Storage Company, i-Institute of Physics ye-Chinese Academy of Sciences, i-Zhongkehai Sodium Technology Co., Ltd. kunye nezinye iiyunithi zeqela leprojekthi, isungule ngokusemthethweni iprojekthi yesizwe engundoqo kunye nenkqubo yophuhliso lweprojekthi ephantsi kwesihloko esithi "i-100 megawatt-iyure yesicelo sokudibanisa i-sodium inkqubo yokudibanisa ibhetri kunye nenkqubo yophando lwe-sodium inkqubo yokudibanisa ibhetri. "Sigxininise ekusebenzeni okuphezulu kombane wokulungiswa kwesikali sombane, ukuhlanganiswa kwenkqubo kunye nokukhusela ukhuseleko kunye nolawulo kunye nobunye ubugcisa obuphambili bokuqhuba uphando, oluyilwe ngamalungelo azimeleyo epropathi yengqondo yokulungiselela ibhetri ye-sodium-ion kunye nobuchwepheshe bokuhlanganiswa kwenkqubo," inkokeli yeprojekthi, iSouth China Grid Guangxi Grid Company, usekela-mlawuli weSebe le-Innovation Gao Lik waziswa.
I-cell-capacity battery cell iyona yunithi esisiseko yenkqubo yonke yokugcina amandla ebhetri ye-sodium-ion. Emva konyaka onesiqingatha wophando, iqela leprojekthi liphuhlise ubomi obude behlabathi, indawo yobushushu ebanzi, ukhuseleko oluphezulu lwe-210Ah ibhetri ye-sodium-ion yokugcina amandla. "Ngokwembono yokusebenza, uhlobo lwethu lwebhetri ye-sodium-ion lunenzuzo yendawo yokushisa ebanzi yokusebenza, ukutshaja ngokukhawuleza kunye nokuphindaphinda okulungileyo, kwaye inokuhlawuliswa kwi-90% kwimizuzu eyi-12," watsho u-Hu Yongsheng, umphandi kwiZiko leFiziksi, i-Chinese Academy of Sciences.
Njengabathathi-nxaxheba abaphambili bezobugcisa kwiprojekthi, i-SouthGrid Energy Storage Company Energy Storage Research Institute kwi-lithium yebhetri yokugcina amandla ukuhlanganiswa kunye nokukhusela ukhuseleko kunye nokulawula kwintsimi inobutyebi bamava ophando, yenza uphando oluphambili lwesizwe kunye nenkqubo yophuhliso "i-lithium-ion ibhetri yokugcina amandla enkqubo yokusetyenziswa komjikelo wobomi bokusetyenziswa kobuchwephesha bokhuseleko". "Nangona imigaqo yokusabela kweebhetri ze-sodium kunye ne-lithium zifana, ukuphuhliswa kwenkqubo yokugcina amandla epheleleyo edibanisa ukutshaja kunye nokukhupha iimpawu zeebhetri ze-sodium zifuna ukoyisa imingeni emitsha," utshilo uLi Yongqi, ingcali yezobuchwepheshe evela kwi-SouthGrid Energy Storage Company, ngemvakalelo.
Ukuthatha ukuhlanganiswa kwenkqubo njengomzekelo, iqela leprojekthi lithatha ngokutsha i-architecture yokugcina amandla esasazwayo esekelwe kumbane ophezulu weebhetri ze-sodium-ion, kwaye yonke inkqubo idibanisa i-88 modular converters, iqonda "imbalelwano enye ukuya kwelinye" kunye namaqela ebhetri, ngelixa i-architecture esasazwayo yendabuko ye-lithium-ion yokuguqula inkqubo yokudibanisa amandla ngaphezu kweemfuno ze-40 kuphela. Injongo ekhawulezileyo yokuphinda kabini inani labaguquleli kukwandisa ukufumaneka kwamandla kunye nokusebenza kakuhle kokuguqulwa kwamandla. Ukuguqulwa kwamandla okusebenza ngokubanzi kwale nkqubo yokugcinwa kwamandla ebhetri ye-sodium ingaphezulu kwe-92%, ngelixa iibhetri ze-lithium ngokuqhelekileyo zingaphantsi kwe-90%, ekulindeleke ukuba zincedise kwaye zithathe indawo ngokufanelekileyo iibhetri ze-lithium, kwaye zisetyenziswe kwindawo enkulu yokugcina amandla e-electrochemical, izithuthi zombane, oomatshini bokwakha kunye nezinye iindawo.
Ngokubhekiselele kukhuseleko lokukhusela kunye nokulawula ukhuseleko, iqela liye laqulunqa isicwangciso solawulo lwe-thermal yenkqubo yokupholisa ulwelo kunye nesethi epheleleyo yokukhusela umlilo kunye nokulawula iteknoloji yenkqubo yokugcina amandla ebhetri ye-sodium-ion, njengesithintelo se-module-level thermal kunye nokucima umlilo ophezulu.
Umahluko weqondo lokushisa phakathi kweeseli zebhetri ze-sodium ezingaphezu kwe-22,000 kwinkqubo yonke ilawulwa ngaphakathi kwe-3 degrees Celsius. Ukusetyenziswa kokubini ukutshatyalaliswa kobushushu kunye nomqobo wokubaleka kwe-thermalglass fiber airgel blanketnjengento yokuthintela i-thermal phakathi kwe-core yombane, i-battery monomer i-thermal runaway yokusabalalisa ixesha lokusasazeka ukusuka kwimizuzu ye-30 ukuya kwiiyure ze-2, yandiswe ngamaxesha e-4, iphucula kakhulu ukhuseleko lwemodyuli yebhetri.
Iqela liphuhlise i-nitrogen eyi-liquid esebenzayo yokucima umlilo, ukupholisa, iteknoloji yokuchasana nokulawula, ekwazi ukucima umlilo wokuqala webhetri ngaphakathi kwemizuzwana ye-5, ukwenza iiyure ze-24 ngaphandle kokuvutha kwakhona kunye nokuqhuma. "I-lithium yangoku kunye neteknoloji yokugcina amandla e-sodium ukukhuthaza ukuphuculwa kweempawu zomnye nomnye ezicacileyo, le seti ye-sodium-ion yenkqubo yokugcina amandla ebhetri yophando kunye nolwelo olusebenzayo lwenitrogen yokucima umlilo, ukupholisa, iteknoloji echasene nolawulo ngokusebenzisa inkqubo yokugcina amandla ebhetri ye-lithium-ion inkqubo yokusetyenziswa komjikelo wobomi besicelo sokuguqulwa kweteknoloji yokhuseleko kwi-lithium, inkqubo yokugcina amandla e-sodium ungqamaniso okokuqala kwisicelo sobunjineli," watsho uLiYongQ kwisicelo sobunjineli.
EyoMqungu 28, 2024, yi Chinese Academy of Engineering Jiang Jianchun academician, Chinese Academy of Sciences, Cheng Shijie academician, Zhang Yue academician, i European Union Academy of Sciences Sun Jinhua academician kunye nezinye iingcali China Machinery Industry Federation IKomiti yoVandlakanyo kwiziphumo zeprojekthi ukwenza uphononongo lovavanyo: inkqubo ye-MWh yogcino lwebhetri ye-electric jikelele kwisikhululo samandla se-10 sokugcina amandla e-MW iphuhliswe liqela leprojekthi ikwinqanaba eliphambili lamazwe ngamazwe.
