Isikhathi saseBeijing simenyezelwe emklomelweni we-Nobel Chemical Award ka-2019, omenyezelwe izolo kusihlwa, nososayensi abathathu ababambe iqhaza kumabhethri e-lithium-ion asetshenziswa cishe kuwo wonke umuntu: uJohn B. Gudarf, M. Stanley Weitan , Ji Ni, bonke bahloselwe ukuba nochwepheshe basekhaya, futhi basebenza kahle emikhakheni yamandla wamandla.

Ukuvuselela ukwenza ibhethri ye-lithium-ion yokuhweba "kulo nyaka imiklomelo yebhethri ye-lithium-ion ifinyelelwe. U-Lin Belin, uProfesa, i-Materials Science and Technology College, i-Shanghai University of Science and Technology. Amabhethri e-lithium-ion afakwe emakethe cishe iminyaka engama-30, imibuthano yezemfundo ibiphezulu kulokhu kusungulwa koMklomelo KaNobel.

Kungani umklomelo weNobel webhethri ye-lithium-ion kulo nyaka? Kucatshangwa ukuthi lokhu kungenxa yokusetshenziswa okubanzi kwamabhethri e-lithium-ion emikhiqizweni ephathwayo njengezimoto zamandla amasha eminyakeni yamuva. Ngaphezu kwalokho, kungase futhi kuhlobane nokucindezela kokunciphisa isikhutha okubangelwa ukushintsha kwesimo sezulu emhlabeni wonke. "Ithimba lethu lishicilele amaphepha kumagazini we-" Joe ", zibikezela lesi sikhathi ngaphambi kuka-2040 kuzoba ngabantu ngokunciphisa ukukhishwa kwe-carbon dioxide, ukuvimbela ukuguquka kwesimo sezulu okuyinhlekelele okokugcina amafasitela.

Ibhethri ye-lithium-ion ibalulekile kumodi entsha yokugcina amandla ekhishwa ikhabhoni ephansi. "Ososayensi abathathu abawine imiklomelo abadluliselwe phambili benza ibhethri ye-lithium-ion yokuhweba. M.

U-Stanley Weitan "unguphayona" wakuqala wamabhethri e-lithium ion. Ngo-1970, wasebenzisa i-titanium sulfide njengento enhle, futhi i-lithium yensimbi yasetshenziswa njengento engalungile ye-electrode, eyenza ibhethri ye-lithium ion yokuqala ye-miniaturized, kodwa ngenxa yokuthi kwakungekho ukukhetha kwezinto ezibonakalayo, ibhethri ye-lithium ion yokuqala kulula kakhulu ukuqhuma. Ngo-1980, uJohn B ¡¤ Gudanaf uhlongoze ukuthi ukusetshenziswa kwama-oxide ensimbi ku-electrode enhle yebhethri, okuhle kakhulu ukuthuthukisa ukusebenza kwamabhethri e-lithium-ion.

Kodwa-ke, akazange athuthukise ibhethri ye-lithium-ion yokuhweba. Kuze kube ngu-1985, lapho i-3rd ye-Note Award - i-Ji Ni ihlanganiswa nensimbi ye-lithium ne-carbon material njengebhethri, ixazulula ngempela inkinga yokuphepha yamabhethri e-lithium-ion. Kusukela lapho, i-lithium ihamba ngempela futhi ishintsha izimpilo zabantu.

Eqinisweni, uJiang Hao, isekela lomqondisi wezimoto zakamuva zikagesi ze-TSLA, kanye neLabhorethri Eyisihluthulelo ye-Ultrafine Material Preparation and Application of Ministry of Education, Ministry of Education, iyafunda, iyinto enhle yenoveli ehlanganisiwe "i-lithium nickellate", enciphisa izinsimbi eziyigugu. Ingxenye ye-cobalt inyusa isilinganiso se-nickel siye ku-80% noma ngaphezulu. Kodwa-ke, akunakuphikwa ukuthi ibhethri le-lithium-ion aliphulwanga ngokuyisisekelo ekwakhiweni okuyisisekelo okuhlongozwe nguGudarf.

Kodwa-ke, u-Su Lin, uprofesa we-Energy and Power Engineering College yase-Shanghai University of Technology, ukhona ukuthi i-lithium element yamanje ilinganiselwe kakhulu, futhi iyingxenye ye-trace element. "Uma wonke ama-ligments omhlaba wamanje asetshenziselwa ukukhiqiza izimoto ezisebenza ngogesi ezintsha, angahlangabezana nezinkulungwane zezigidi zezimoto ezintsha ezisebenza ngamandla. Ngakho-ke, ngenkathi ibhethri ye-lithium-ion isetshenziswa kabanzi, idinga futhi ukuvumelanisa ukuze kucutshungulwe kabusha.

Ucwaningo lwesayensi akuyona imizamo yosuku yokulalela i-Chemical Nobold. Umeme uM. U-Stanley Witly Han waya e-Shanghai, futhi waya e-Shaoxing ukuze abambe iqhaza kuNgqungquthela ye-14 ye-China-US Electric Automotive and Battery Technology Information Exchange.

"Mina no-Weitan Han kufanele sibone izikhathi eziningana ngonyaka." "U-Yoshino uphinde wamema ukuvakashela e-Shanghai, futhi ngizizwa ngokushesha ekuthuthukisweni kwamabhethri e-lithium-ion nezimoto ezintsha zamandla, futhi ukuhlolwa komkhiqizi webhethri ye-lithium-ion wezwe lami kuphezulu kakhulu.

Wahleka, ngosizo lwamandla obuchwepheshe baseJapane, ibhethri ye-lithium-ion inomphumela omkhulu ku-R <000000> D, futhi inkampani yezwe lami nayo isemhlabeni, ivumela ibhethri ye-lithium-ion kabusha ikusasa elicacile, "naphezu kwenqubo yezinkulungwane zobuchwepheshe, Nokho, Ucwaningo alulona usuku losuku, futhi luyiqiniso incazelo yesayensi nobuchwepheshe. “Ithimba labacwaningi bezwe lami nalo liyafaka isandla. Iphrojekthi ye-"Biracelium" yethimba le-Mitailifeng iqedele "ukukhiqiza ibhethri ye-lithium enamandla aseBrithani kanye nenqubo yesicelo sayo" iphrojekthi, kulo nyaka iwine umklomelo wesibili weNational Science and Technology Progress Award.

Wathi kungakhathaliseki ukuthi imoto entsha yamandla, umzila wesitimela, iloli yezokuthutha kanye namanye amathuluzi okuthutha kagesi, kanye nesistimu yokugcina igridi ehlakaniphile, ucwaningo lwezwe lami nokuthuthukiswa kanye nokukhiqizwa emkhakheni we-lithium iron phosphate ion battery applications kube phambi kwezwe. "Isu elisha alizalwa ngesikhathi sokuphefumulelwa, kodwa kancane kancane lithuthukiswa ngesisekelo sokuhlola okuqhubekayo nokusebenza kweningi labacwaningi. .
