Amandla angamandla aqhuba ukuthuthukiswa komphakathi wesintu.Eminyakeni yamuva nje, njengemigomo yentuthuko yomhlaba wonke "ye-carbon peak, carbon neutral", ngokusekelwe ekusetshenzisweni kwamandla avuselelekayo okugcinwa kwamandla amaningi kanye nokuthandwa kwezimoto ezintsha zamandla sekuphenduke umkhuba ongenakugwemeka wentuthuko, abantu bezokuphepha, ukuvikelwa kwemvelo, amandla aphezulu. ukuminyana, izindleko eziphansi zebhethri zidinga okuphuthumayo, futhi ukuze ososayensi bahlole isizukulwane esisha sebhethri babeke phambili izidingo eziphezulu.Kulo mongo, amabhethri e-zinc ion okukhipha amanzi athathwa njengobunye bobuchwepheshe obunamandla bokugcina amandla esimeme ngenxa yokuphepha kwawo okuphezulu, izindleko eziphansi kanye nobungane bemvelo.Isiqondiso socwaningo sika-Li Xinliang, uprofesa eSikoleni seFiziksi saseZhengzhou University, sihlobene kakhulu nalo mkhakha.

Eminyakeni edlule, u-Li Xinliang uye wazinikela ocwaningweni lwesayensi, futhi wenza uchungechunge lwezimpumelelo zocwaningo lwesayensi olusha ocwaningweni nasekuthuthukisweni kwebhethri lokudonsa amanzi / uhlelo lokugcina amandla ebhethri le-halogen kanye nemishini yokuzivikela ye-electromagnetic wave.” Ngenhlanhla, ucwaningo lwami siqu. izithakazelo zihambisana nezidingo zamasu kazwelonke, ngakho ngibunqobile ubunzima ngafuna iqiniso nokuzibophezela.”

Phansi kuya emhlabeni, isinyathelo ngesinyathelo emgwaqeni wocwaningo lwesayensi

Konke kufanele kube phansi ukwenza, ngoba kulula, akunzima.Indlela yocwaningo lwesayensi ka-Li Xinliang ifana nokuvezwa kwabafundi abaningi abajwayelekile.Ngo-2011, wangeniswa e-Zhengzhou University of Light Technology, wenza izifundo ze-physics kanye ne-electronic Engineering.Ucwaningo lokugcinwa kwamandla lwalungadumile ngaleso sikhathi.Ekolishi, ngesikhathi ephupha, wazizwa edidekile.

Ngocwaningo olujulile locwaningo lokugcina amandla, u-Li Xinliang kancane kancane wathola ukuthi impumelelo yocwaningo lwesayensi kulo mkhakha ingasetshenziswa futhi iguqulwe ngempela.Ukuze aqhubeke nokufunda ucwaningo lwesayensi emikhakheni ehlobene, wafundela iziqu ze-master kanye nezodokotela eNorthwestern Polytechnical University naseCity University of Hong Kong ngemva kokuthweswa iziqu.Kwaba futhi esigabeni sakamuva lapho ahlangana khona noSolwazi Yin Xiaowei kanye noSolwazi Zhi Chunyan, owaba nomthelela obalulekile emsebenzini wakhe wocwaningo lwesayensi.

U-Li Xinliang washo ngokungananazi ukuthi waba nesikhathi sokudideka ngemuva kokuphothula iziqu.Kwakungaphansi kokuqondisa kukaSolwazi u-Yin Xiaowei, umfundisi wenkosi yakhe, owabeka isiqondiso sakhe socwaningo ezintweni zokumelana nemisebe futhi waqala umgwaqo wocwaningo lwesayensi isinyathelo nesinyathelo.Ngesikhathi ehlala e-City University yaseHong Kong, uLi Xinliang, ngaphansi kokuqondisa komqondisi wobudokotela uSolwazi Zhi Chunyan, uhlanganise ucwaningo ngezinto zokumelana nemisebe nezihloko zokugcina amandla, futhi wenza ucwaningo mayelana nokugcinwa kwamandla aphephile kanye nezinto zikagesi eziguquguqukayo ezigqokekayo, ngakho-ke. njengokufeza izidingo ezingaba khona zezwe emikhakheni yomphakathi kanye nebalulekile.Ngaphezu kwalokho, phakathi neziqu zakhe ze-masters, abafundisi ababili banikeze u-Li Xinliang indawo yocwaningo lwesayensi yamahhala, ukuze akwazi ukudlala ngokugcwele esimisweni sakhe esizimele futhi ahlole njalo futhi aqhubekele phambili eqhutshwa intshisekelo yakhe.” ukuhlela kanye nemigomo yesikhathi esizayo yocwaningo lwesayensi yayingacacile.Kwakungaphansi kwesiqondiso sabo sesinyathelo ngesinyathelo ukuthi ngakhula kakhulu.Ngaphandle kosizo lwabo, ngicabanga ukuthi anginalo ithuba lokungena kulo mgwaqo wocwaningo lwesayensi. ”kusho uLi Xinliang.

Ukuze enze ucwaningo lwakhe lwesayensi lusebenze ngokushesha ngangokunokwenzeka, ngemva kokuthweswa iziqu, u-Li Xinliang wajoyina i-City University yaseHong Kong-Hong Kong Big Zinc Energy Co., Ltd. wenza ucwaningo lwesayensi lokugcina amandla aphephile.U-Li Xinliang wazi kahle ukuthi kusenendlela ende okufanele ihambe ukusuka elabhorethri kuya ekusetshenzisweni kwebhizinisi, ikakhulukazi ohlelweni lwemiphumela yocwaningo lwaselabhorethri ekukhiqizeni imikhiqizo eminingi, kuzoba nezinkinga eziningi "ezinkulu" futhi ubunzima.Ngalesi sikhathi sokusebenza eHong Kong Big Zinc Energy Co., Ltd., uLi Xinliang uzame ukuguqula umsebenzi wakhe wocwaningo lwesayensi usuke osuselwe ezinkingeni uye ogxile ocwaningweni futhi ogxile ekusetshenzisweni, okwanikeza umbono obanzi wocwaningo lwakhe lwesayensi lwesikhathi esizayo. izihloko.

 Ngokusekelwe esimweni samanje, ukusungulwa kocwaningo lwebhethri lesistimu yamanzi

NgoSepthemba 2020, i-China yasho ngokucacile umgomo “we-carbon peak” ngo-2030 kanye “nokungathathi hlangothi kwekhabhoni” ngo-2060.

Njengoba amandla amasha eba umkhuba namuhla, amabhethri asetshenziswe kabanzi ezimotweni zamandla amasha, imishini kagesi yabathengi kanye nazo zonke izinhlobo zezinhlelo zamandla okugcina amandla.Kulesi sizinda senhlalo, uLi Xinliang uthwala umthwalo wabacwaningi besayensi futhi uzimisele ukwenza okuthile emikhakheni ehlobene.

Njengoba sonke sazi, amabhethri e-lithium-ion, asetshenziswa kabanzi ezimotweni zamandla amasha, anezinzuzo zokuminyana kwamandla aphezulu, umthamo omncane, isisindo esilula kanye nempilo ende yenkonzo.Kodwa-ke, amabhethri e-lithium adinga ukubekwa uphawu okuphezulu kakhulu, ikakhulukazi phakathi nesevisi ukuze ahlukanise amanzi nomoya-mpilo, uma ibhethri selihlangabezane njengokushayisana, i-extrusion nokunye ukupakishwa kwebhethri, ibhethri lingase liqalise uchungechunge lwe-chain exothermic reaction, ngisho nomlilo nokuqhuma... Kulo mongo, u-Li Xinliang ukholelwa ukuthi ukuthuthukiswa kwamabhethri amanzi aphephe kakhudlwana, aluhlaza, futhi azinzile ukuze ahlangabezane nezidingo zenkundla yokugcina amandla aphephile kunaka kakhulu izici zokuphepha kwebhethri, ikakhulukazi izinto zikagesi ezigqokekayo ngisho nemishini yezokwelapha efakwe ngaphakathi. ukuthintana ngqo nomzimba womuntu.

U-Li Xinliang uthe, ibhethri lokudonsa amanzi njengobuchwepheshe obusha bebhethri, ngokuphepha kwangaphakathi kanye nokushaja okusheshayo nekhono lokuphuma, linganweba impilo yesevisi yebhethri futhi ibhethri inamandla okubhekana nezinhlobonhlobo zokugcinwa kwamandla / isimo samandla esinamandla, esimweni esivuselelekayo. uhlelo lokugcina amandla, izimoto zikagesi kanye nemikhiqizo ye-elekthronikhi ephathekayo kanye neminye imikhakha inethuba elibanzi lokufaka isicelo.” Ngakho-ke, inkomba enkulu yocwaningo lwethu manje ukuthuthukisa amabhethri okukhipha amanzi ukuze kugcwaliswe igebe kuchungechunge lokuhlinzekwa kwempahla emakethe yamanje yokugcina amandla ephephile. amabhethri e-lithium-ion.Okwamanje, ocwaningweni oluzayo, siphinde sicabangele ukufaka nezindaba zemisebe ezizindeni eziyinkimbinkimbi zikamagnetic / infrared ekuhloleni okuguquguqukayo kokuphepha kwesevisi.” Wathi.

Kule nqubo, u-Li Xinliang nethimba lakhe labacwaningi baqale benza ukwakheka okuphelele kwebhethri lokudonsa amanzi ukuze kuqinisekiswe ukuguquguquka okuphezulu kwengxenye ngayinye yezingxenye zebhethri.Okwesibili, bethule izinhlelo zokuqapha izinga lokushisa kanye ne-voltage, kanye nemishini yokuvikela i-overcurrent kanye ne-overvoltage, ukuqapha ukusebenza kwebhethri ngesikhathi sangempela kanye nokulandelela ukwenzeka kwezimo ezingavamile.Ngaphezu kwalokho, basebenzisa i-electrode ne-electrolyte ukuguqulwa ukuze bathuthukise ukusebenza kwe-electrochemical of drainage amabhethri kuyilapho benciphisa ukusabela okungenzeka ohlangothini enqubweni yesevisi yamabhethri okudonsa amanzi, ukuze kuthuthukiswe ukuphepha nokuzinza kwamabhethri okudonsa amanzi.

Isithwali se-electrolyte —— amanzi ayincibilikisi enezindleko eziphansi, evuselelekayo futhi evumelana nemvelo.Uma kuqhathaniswa ne-solvent ephilayo kumabhethri endabuko emvelo, amanzi anokuphepha okungokwemvelo kanye nezindleko eziphansi, anomthelela omncane endaweni ezungezile.Ngaphezu kwalokho, amabhethri amanzi nawo ayavuseleleka.Amanzi nosawoti wensimbi yizinsiza ezivuselelekayo, ezinganciphisa ukusetshenziswa kwezinsiza futhi zinciphise isidingo sezinsimbi ezingavamile.Kodwa-ke, ukusebenzisa amanzi njenge-electrolyte, kunenkinga, okungukuthi, iwindi le-voltage elizinzile lamanzi lincane, futhi lingasabela nge-electrode, ikakhulukazi ukweqisa okungalungile kwensimbi, okuholela ekuncishisweni kwempilo yesevisi yebhethri.Ngokwesisekelo semiphumela yocwaningo efanele, u-Li Xinliang uzibophezele ekuthuthukiseni amabhethri e-halogen anamandla amakhulu.

Ngenxa yezinzuzo zamandla aphezulu e-redox, izindleko eziphansi kanye nezinsiza eziningi, i-halogen ibonisa amathuba amahle okusebenza ezintweni ze-electrode.Kulesi sizinda, ithimba le-Li Xinliang lenze isu eliphumelelayo lokuguquguquka kwe-electrolyte ukuze kutholakale i-halogen ohlelweni lokuguqula amandla okuguqulwa okuguquguqukayo okuguquguqukayo, futhi likhethe usawoti we-halide ophephe kakhulu njengomthombo we-halogen osebenzayo esikhundleni sento eyodwa ye-halogen njengobufakazi bomqondo, yakha i-halogen esebenza kakhulu engakaze ibonwe esekelwe kubhethri lamakhemikhali lokuguqulwa kwama-multielectron.Kuhle ukubalula ukuthi ngochungechunge locwaningo lwesayensi nokuhlola, bakhuphule ngempumelelo ukuminyana kwamandla amabhethri e-halogen angaphezu kuka-200% yenani lokuqala, bathuthukisa kakhulu amandla okugcina amandla amabhethri e-halogen.Ngaphezu kwalokho, indlela entsha ye-redox eyakhiwe ithimba lika-Li Xinliang ikhombisa ukuguquguquka okuhle kakhulu kwezinga lokushisa eliphansi, okunweba kakhulu izimo zokusetshenziswa kwamabhethri e-halogen.

 Yehlisa isimo sengqondo sethu futhi ukhuthaze ucwaningo lwesayensi

Ucwaningo lwesayensi, isikhathi eside.U-Li Xinliang uyazi ukuthi ukuthuthukiswa kokusebenza kwamabhethri okudonsa amanzi akutholakali ngobusuku obubodwa.Ngezinye izikhathi ukuhlolwa kokusebenza kungase kuthathe unyaka noma iminyaka ukuze kubonakale imiphumela, okuzobhekana nochungechunge lwezinkinga.” Lapho sibhekana nezinkinga, okokuqala, kumelwe sizifunde kabanzi izincwadi futhi sifunde kokuhlangenwe nakho nasezifundweni zabanye.Okwesibili, kumele sixoxisane nabeluleki bethu kanye nozakwethu futhi sibonisane, okuzohlala kunezithelo. ”kusho uLi Xinliang.

Unyaka ka-2023 uyinkathi entsha yoshintsho empilweni ka-Li Xinliang.Kulo nyaka, emi eneminyaka engu-30 ubudala, ubuyele edolobheni lakubo esifundazweni saseHenan futhi weza eSikoleni SePhysics saseZhengzhou University ukuze enze umsebenzi wocwaningo lwesayensi.” ' tech depression '.” Uthe.Njengokwethulwa kwamakhono ocwaningo lwesayensi, iSifundazwe saseHenan, iNyuvesi yaseZhengzhou kanye neSikole SeFiziksi saseZhengzhou University zinikeze u-Li Xinliang ukwesekwa okukhulu endaweni yakhe yokuphila kanye nocwaningo lwesayensi, futhi kwamsiza ukuba aqede ukukhathazeka kwakhe ekhaya.Manje, esikhathini esingaphezu kwesigamu sonyaka, usesungule ithimba lakhe labacwaningi, kodwa futhi wanquma isiqondiso somsebenzi wesikhathi esizayo ngokwesisekelo sakhe socwaningo.” Okokuqala, sihlose ukuthuthukisa ukusebenza nokuzinza kwebhethri, futhi sithuthukise ezinye izinhlelo zokuhlola zendlela yomngcele kanye nezindaba zesayensi ezivulekile kulo mkhakha, ngokusebenzisa inkambiso yocwaningo lwesayensi eminingi, ukwahlulela ukuthi izixazululo ezifanele zingenzeka yini.Kulesi sikhathi, kungaba ngcono ukuxazulula izinkinga ezithile zobuchwepheshe, ukubeka phambili amamodeli athile ayisisekelo etiyetha, futhi siqhubekisele phambili isinyathelo esincane esincane kulo mkhakha.” Uthe.

Umgwaqo ongaphambili usekude.Ekuthuthukisweni nasekuhloleni ubuchwepheshe bebhethri ye-drainage, ukwehluleka nokukhungatheka yizinto ezivame kakhulu, kodwa u-Li Xinliang uhlala ekholelwa ukuthi kuyohlale kunezinzuzo.Esikhathini esizayo esiseduze, unethemba lokwakha ithimba labacwaningi eliyingqayizivele elisekelwe ekugcinweni kwamandla okuyinkimbinkimbi nokuphephile, agxilise ucwaningo lwakhe ngezidingo ezinkulu zezwe zobuchwepheshe, futhi alwele ukwenza owakhe umnikelo.” Ngokuthuthuka kwezobuchwepheshe kanye nokuba nokwenzeka kwezomnotho okuthuthukisiwe, singakwazi. silindele ukubona ubuchwepheshe bamabhethri e-drainage bungena kancane kancane emakethe eminyakeni ezayo ukuze bunikeze izixazululo zamandla ezithembekile neziphephile zemvelo ezweni, umphakathi kanye nabathengi abajwayelekile.” Kusho uLi Xinliang ngokuzethemba.
