Ibikoresho byingirakamaro kuri Bateri ya Litiyumu

Mu rwego rwo kutabogama kwa karubone hamwe n’isi yose yo gukwirakwiza amashanyarazi, lithium, nkibikoresho byingenzi mu murima wa batiri, biteganijwe ko izakomeza kungukirwa n’ingufu zisukuye mu mbaraga zayo no kubika ingufu.Litiyumu ifite urunigi rwuzuye, rukora ibicuruzwa biva mu bucukuzi bw'amabuye y'agaciro n'ibiyaga by'umunyu kugeza hagatikarubone, lithium hydroxide na lithium yicyuma, hamwe ninganda zisanzwe zo hasi (gushonga ibyuma, amavuta, ibirahuri bya ceramique, nibindi), ibikoresho bishya (synthesis organic, biomedicine) nimbaraga nshya (bateri 3C, bateri yumuriro, nibindi) nibindi byerekanwa kuruhande iminyururu yuzuye.Litiyumu hydroxideni umwe mu myunyu itatu ya lithium mumurongo wa lithium.Ibisabwa byo hasi cyane biva mumashanyarazi ya batiri yumuriro, umurima wa bateri wabaguzi, hamwe ninganda zinganda zihagarariwe no gukora amavuta ashingiye kuri lithium hamwe nubutaka bwikirahure.Imiterere yacyo nyamukuru irimo hydroxide ya Anhydrous (LiOH) na lithium hydroxide monohydrate (LiOH · H2O).

Litiyumu hydroxide ni ibikoresho by'ibanze mu rwego rwa bateri y’amashanyarazi, cyane cyane ibikoresho bya nikel ternary cathode ikoreshwa cyane muri bateri zifite ingufu nyinshi, kandi ni isoko ya lithium yingenzi mu musaruro wayo.Ibikoresho byo hejuru bya nikel bigizwe ahanini na NCM811 na NCA.Amasosiyete y'Abashinwa akora cyane cyane NCM811, naho amasosiyete y'Abayapani na Koreya akora cyane cyane NCA.Kugeza ubu, ibinyabiziga bitandukanye byingufu zifite ibikoresho bya bateri nini ya nikel ndende bifite intera irenga kilometero 500.Igice cya bateri yumuguzi kirimo terefone zigendanwa, tableti, ibikoresho bya TWS, na drone.

Ibikoresho byinshi bya nikel bisaba ubushyuhe bwa 700 ~ 800 ° C, ariko karubone ya lithium ikunze gucumurwa nka 900 ° C kugirango ikoreshe ibintu byiza, mugihe aho gushonga kwa hydroxide ya lithium ari 471 ° C, hamwe nubushakashatsi bukomeye kandi bwangirika cyane.Imiterere yumubiri nubumashini ituma hydroxide ya lithium ari ntangarugero muguhindura ubushyuhe bwibikoresho bya nikel ternary ya cathode yo hejuru, bityo rero ni amahitamo byanze bikunze kubikoresho bya nikel ndende.

Inganda eshatu za mbere za batiri kwisi mubijyanye nubushobozi bwashyizweho na bateri yingufu zose zasobanuye neza ko ternary-nikel nini ninzira nyamukuru yiterambere (ibihe bya Ningde - NCM622 / 811, Panasonic yu Buyapani - NCA, LG Chem yo muri Koreya yepfo - NCM622 / 811), umugabane w'isoko CR3 wageze hafi bibiri bya gatatu mugihe ukomeje umuvuduko mwinshi.Mu bihe biri imbere, hamwe nubushobozi bwiyongereye bwa nikel ternary mu binyabiziga bishya byingufu, hydroxide ya lithium nkibikoresho fatizo nabyo bizatangiza umwanya witerambere utigeze ubaho.
