Kutshanje, isikhululo samandla sokugcina amandla sebhetri ye-sodium-ion esikhulu saseTshayina – isikhululo samandla sokugcina amandla sebhetri ye-Volin sodium-ion siqalise ukusebenza eNanning, eGuangxi. Le yinkqubo ephambili yophando nophuhliso lwesizwe ethi “iteknoloji yokugcina amandla yebhetri ye-sodium-ion yeyure ezili-100 megawatt” yeprojekthi yokubonisa iprojekthi yesigaba sokuqala seprojekthi, ubungakanani obufakiweyo be-2.5 megawatts/10 megawatts-hours.
Isikhululo samandla sityalwe kwaye sakhiwe yiGuangxi Power Grid Company yeSouthern Power Grid, kwaye isikali sale nqanaba yi-10 MWh. Isikali sisonke seprojekthi siya kufikelela kwi-100 MWh, enokuvelisa iidigri ezingama-73 ezigidi zombane ococekileyo ngonyaka.

Isikali sisonke seprojekthi siya kufikelela kwi-100 MWh, enokuvelisa iidigri ezingama-73 ezigidi zombane ococekileyo ngonyaka, ngokulinganayo kunciphisa ukukhutshwa kwekhabhoni diokside ngeetoni ezingama-50,000, kwaye kuhlangatyezwane neemfuno zombane zabasebenzisi bezindlu abangama-35,000.
Xa kuthelekiswa nokugcinwa kwamandla ebhetri ye-lithium-ion, "abazalwana" bagcina amandla ebhetri ye-sodium-ion, kulula ukuyikhupha, ixabiso eliphantsi, ukusebenza ngcono kumaqondo obushushu aphantsi, kwindawo yokugcina amandla enkulu ineengenelo ezicacileyo. "Ukugcinwa kwamandla ebhetri ye-sodium-ion kwinqanaba lophuhliso, ixabiso leendleko lingancitshiswa ngama-20% ukuya kuma-30%, phantsi kwengcamango yokuphucula ngokupheleleyo isakhiwo sebhetri kunye nenkqubo, ukuphucula izinga lokusetyenziswa kwezixhobo kunye nobomi bomjikelo, ixabiso lombane lingahlolwa ukuya kwi-0.2 yuan / kWh, kukukhuthaza ukusetyenziswa koqoqosho kohlobo olutsha lokugcina lwendlela ebalulekileyo yetekhnoloji," utshilo umgcini wamandla kazwelonke uChen Man, usekela-nobhala-jikelele weKomiti yoBugcisa boMbane yeSizwe kunye nengcali yobugcisa kwinqanaba leqhinga leGridi yoMbane yaseMzantsi.
Nangona umsebenzi waseTshayina kuphando nophuhliso, imveliso, ukubekwa emgangathweni, ukukhuthazwa kwemarike kunye nokusetyenziswa kweemveliso zebhetri ye-sodium-ion uqhubeka ngokupheleleyo, akukho mzekelo wamazwe ngamazwe wokusetyenziswa kwetekhnoloji yebhetri ye-sodium-ion kwizikhululo zamandla zokugcina amandla ezinkulu.
NgoNovemba ka-2022, iGuangxi Power Grid Company, ngokubambisana neSouth Grid Energy Storage Company, i-Institute of Physics of the Chinese Academy of Sciences, iZhongkehai Sodium Technology Co., Ltd. kunye nezinye iiyunithi zeqela leprojekthi, baqalise ngokusesikweni iprojekthi yenkqubo yophando nophuhliso lwesizwe eyintloko, umxholo ophantsi wesihloko esithi “iteknoloji yokudibanisa inkqubo yokugcina amandla yebhetri ye-sodium-ion yeyure ezili-100 megawatt kunye nomboniso wesicelo”, uphando olujolise ekulungiseni umsebenzi. “Sigxila ekulungiseleleni isikali sombane esisebenza kakuhle, ukuhlanganiswa kwenkqubo kunye nokuthintela ukhuseleko kunye nolawulo kunye nezinye iiteknoloji eziphambili zokwenza uphando, ezenziwe ngamalungelo epropathi yengqondo azimeleyo okulungiselela ibhetri ye-sodium-ion kunye netekhnoloji yokudibanisa inkqubo,” inkokeli yeprojekthi, iSouth China Grid Guangxi Grid Company, usekela-mlawuli weSebe leMicimbi yeNguqulelo uGao Lik wazisa.
Iseli yebhetri enomthamo ophezulu yiyunithi esisiseko yenkqubo yokugcina amandla yebhetri ye-sodium-ion. Emva konyaka onesiqingatha sophando, iqela leprojekthi lenze ibhetri yokuqala yehlabathi yokugcina amandla ehlala ixesha elide, ubushushu obubanzi, ukhuseleko oluphezulu lwe-210Ah sodium-ion. “Ngokombono wokusebenza, uhlobo lwethu lwebhetri ye-sodium-ion luneengenelo zobushushu obubanzi bokusebenza, ukutshaja ngokukhawuleza kunye nokuphindaphinda okuhle, kwaye inokutshajwa ukuya kuthi ga kwi-90% kwimizuzu eli-12,” utshilo uHu Yongsheng, umphandi kwi-Institute of Physics, i-Chinese Academy of Sciences.
Njengabathathi-nxaxheba abaphambili kwezobugcisa kule projekthi, iSouthGrid Energy Storage Company Energy Storage Research Institute kudibaniso lwenkqubo yokugcina amandla ebhetri ye-lithium kunye nokuthintela nokulawula ukhuseleko kweli candelo inamava amaninzi ophando, yenza inkqubo yophando nophuhliso lwesizwe "ukusetyenziswa komjikelo wobomi benkqubo yokugcina amandla ebhetri ye-lithium-ion ubuchwephesha bokhuseleko". "Nangona imigaqo yokusabela kweebhetri ze-sodium kunye ne-lithium ifana, uphuhliso lwenkqubo yokugcina amandla epheleleyo edibanisa iimpawu zokutshaja nokukhupha iibhetri ze-sodium kufuna ukoyisa imingeni emininzi emitsha," utshilo uLi Yongqi, ingcali yezobugcisa evela kwiSouthGrid Energy Storage Company, eneemvakalelo.
Ukuthatha ukuhlanganiswa kwenkqubo njengomzekelo, iqela leprojekthi lisebenzisa ubuchule bokwakha ulwakhiwo lwamandla asasazwayo olusekelwe kumbane ophezulu weebhetri ze-sodium-ion, kwaye yonke inkqubo idibanisa ii-converter zemodyuli ezingama-88, zenza "unxibelelwano lomntu omnye komnye" kunye namaqela ebhetri, ngelixa uyilo lwendabuko olusasazwayo lwenkqubo yokugcina amandla e-lithium-ion lufuna ukudibanisa ii-converter ezingaphezu kwama-40. Injongo ekhawulezileyo yokuphinda kabini inani lee-converter kukwandisa ukufumaneka komthamo kunye nokusebenza kakuhle kokuguqulwa kwamandla. Ukusebenza kakuhle kokuguqulwa kwamandla kwale nkqubo yokugcina amandla ebhetri ye-sodium kungaphezulu kwama-92%, ngelixa iibhetri ze-lithium ngokubanzi zingaphantsi kwama-90%, okulindeleke ukuba zizalise kwaye zithathe indawo yeebhetri ze-lithium ngokufanelekileyo, kwaye zisetyenziswe kwindawo yokugcina amandla e-electrochemical enkulu, izithuthi zombane, oomatshini bokwakha kunye nezinye iindawo.
Ngokuphathelele ukuthintela nokulawula ukhuseleko, iqela liphuhlise icebo lokulawula ubushushu kwinkqubo yokupholisa ulwelo kunye neseti epheleleyo yetekhnoloji yokuthintela nokulawula umlilo kwinkqubo yokugcina amandla ebhetri ye-sodium-ion, efana nomqobo wobushushu okwinqanaba lemodyuli kunye nokucima umlilo okusebenzayo kakhulu.
Umahluko kubushushu phakathi kweeseli zebhetri yesodiyam ezingaphezu kwama-22,000 kwinkqubo yonke ulawulwa ngaphakathi kwama-degrees Celsius ama-3. Ukusetyenziswa kobushushu obucothayo kunye nobushushu obubalekayo.ingubo yeglasi yefayibha ye-airgelNjengesixhobo sokuthintela ubushushu phakathi kombindi wombane, ixesha lokusasazeka kwe-monomer yebhetri ukusuka kwimizuzu engama-30 ukuya kwiiyure ezi-2, landiswa ukuya kumaxesha ama-4, nto leyo ephucula kakhulu ukhuseleko lwemodyuli yebhetri.
Iqela liphuhlise iteknoloji yokucima umlilo esebenza kakuhle nge-nitrogen engamanzi, ukupholisa, kunye nokuthintela ukutshisa, ekwaziyo ukucima umlilo wokuqala webhetri kwimizuzwana emi-5, ukuze ikwazi ukwenza iiyure ezingama-24 ngaphandle kokutshisa kwakhona nokuqhuma. “Iteknoloji yangoku yokugcina amandla e-lithium kunye ne-sodium ukukhuthaza ukuphuculwa kweempawu zomnye nomnye ngokucacileyo, olu seti yophando lwenkqubo yokugcina amandla ebhetri ye-sodium-ion kunye neteknoloji yokucima umlilo esebenza kakuhle nge-nitrogen engamanzi, ukupholisa, kunye nokuthintela ukutshisa ngokusebenzisa inkqubo yokugcina amandla ebhetri ye-lithium-ion umjikelo wobomi besicelo sokuguqulwa kweteknoloji yokhuseleko kwi-lithium, ukuvumelanisa inkqubo yokugcina amandla e-sodium okokuqala kwisicelo sobunjineli,” utshilo uLiYongQi.
Ngomhla wama-28 kuJanuwari 2024, yi-Chinese Academy of Engineering uJiang Jianchun academician, i-Chinese Academy of Sciences, i-Cheng Shijie academician, i-Zhang Yue academician, i-European Union Academy of Sciences Sun Jinhua academician kunye nezinye iingcali ze-China Machinery Industry Federation Appraisal Committee malunga neziphumo zeprojekthi ukuze benze uphononongo lovavanyo: itekhnoloji iyonke ye-"10 MWh sodium ion battery energy storage system for electric energy storage power stations" eyenziwe liqela leprojekthi ikwinqanaba eliphambili lamazwe ngamazwe.
