Ni ubuhe buryo bwiterambere bwa titanium oxyde lithium-ion ya tekinoroji ya batiri haba mu gihugu ndetse no mu mahanga?

Kuva inganda za batiri za lithium-ion mu 1991, grafite nicyo kintu cyiganje muri electrode mbi kuri bateri.Litiyumu titanate, nkubwoko bushya bwibikoresho bya electrode mbi ya bateri ya lithium-ion, byitabiriwe mu mpera za 90 kubera imikorere myiza.Kurugero, ibikoresho bya lithium titanate birashobora kugumana urwego rwo hejuru rwimitunganyirize mumiterere yabyo ya kirisiti mugihe cyo kwinjiza no gukuraho ioni ya lithium, hamwe nimpinduka ntoya muburyo bwa lattice (ihinduka ryijwi
Ibikoresho bya "zero strain" byongera cyane ubuzima bwa cycle ya bateri ya lithium titanate.Litiyumu titanate ifite umuyoboro udasanzwe wa lithium ion ikwirakwizwa hamwe na spinel imiterere, ifite ibyiza nkibintu byiza biranga imbaraga hamwe nubushyuhe bwo hejuru kandi buke.Ugereranije nibikoresho bya karubone bitari byiza, lithium titanate ifite ubushobozi burenze (1.55V hejuru ya lithium metallic metallic), ibyo bikaba bivamo urwego rukomeye-rwamazi rusanzwe rukura hejuru ya electrolyte na electrode mbi ya karubone idakora hejuru ya lithium titanate .
Icy'ingenzi cyane, biragoye ko dendrite ya lithium ikora hejuru ya lithium titanate murwego rwa voltage yo gukoresha bateri isanzwe.Ibi ahanini bivanaho amahirwe yumuzunguruko mugufi wakozwe na lithium dendrite imbere muri bateri.Umutekano rero wa bateri ya lithium-ion hamwe na lithium titanate nka electrode mbi kuri ubu iri hejuru cyane mubwoko bwose bwa bateri ya lithium-ion umwanditsi yabonye.
Abenshi mu bakora inganda bumvise ko bateri ya lithium yubuzima bwa lithium titanate isimbuza grafite kuko ibikoresho bibi bya electrode bishobora kugera ku bihumbi mirongo, birenze kure cyane ya bateri zisanzwe za lithium-ion, kandi bizapfa nyuma yizunguruka ibihumbi bike gusa. .
Bitewe nuko abanyamwuga benshi ba lithium-ion babigize umwuga batigeze batangira rwose gukora ibicuruzwa bya lithium titanate, cyangwa babikoze inshuro nke gusa bikarangira byihuse iyo bahuye nibibazo.Ntabwo rero bashoboye gutuza no gutekereza neza kuberako bateri gakondo za lithium-ion zakozwe neza zishobora kurangiza igihe cyigihe cyo kwishyurwa 1000-2000 no gusohora?

Ese impamvu yibanze yubuzima bwigihe gito cya bateri gakondo ya lithium-ion bitewe nimwe mubice byingenzi - umutwaro uteye isoni wa grafite ya electrode mbi?Iyo grafite ya electrode itari nziza isimbuwe na spinel yo mu bwoko bwa lithium titanate mbi ya electrode, sisitemu ya chimique ya litiro-ion isa cyane irashobora kuzunguruka inshuro ibihumbi mirongo cyangwa ibihumbi magana.
Byongeye kandi, iyo abantu benshi bavuga kubyerekeranye ningufu nke za bateri ya lithium titanate, birengagiza ikintu cyoroshye ariko cyingenzi: ubuzima bwigihe kirekire cyane, umutekano udasanzwe, imbaraga zidasanzwe ziranga imbaraga, nubukungu bwiza bwa bateri ya lithium titanate.Ibiranga bizaba urufatiro rukomeye rwinganda nini za lithium-ion zibika ingufu.
Mu myaka icumi ishize cyangwa irenga, ubushakashatsi kuri tekinoroji ya batiri ya lithium titanate yagiye itera imbere haba mu gihugu ndetse no ku rwego mpuzamahanga.Uruganda rwarwo rushobora kugabanywa mugutegura ibikoresho bya lithium titanate, gukora bateri ya lithium titanate, guhuza sisitemu ya batiri ya lithium titanate, hamwe nibisabwa mumodoka yamashanyarazi no kumasoko yo kubika ingufu.
1. Ibikoresho bya Litiyumu
Ku rwego mpuzamahanga, hari amasosiyete akomeye mu bushakashatsi no mu nganda ibikoresho bya lithium titanate, nka Oti Nanotechnology yo muri Amerika, Ishihara Industries yo mu Buyapani, na Johnson & Johnson bo mu Bwongereza.Muri byo, ibikoresho bya lithium titanate yakozwe na titanium yo muri Amerika bifite imikorere myiza mubijyanye nigipimo, umutekano, ubuzima bwa serivisi ndende, nubushyuhe bwo hejuru kandi buke.Nyamara, kubera uburyo bwo gukora cyane burebure kandi busobanutse neza, igiciro cyumusaruro kiri hejuru cyane, kuburyo bigoye gucuruza no kuzamura.
