Ha indasteri ea likoloi tsa motlakase (EV) e ntse e hōla, ho joalo le ka lipatlisiso le nts'etsopele ea libeteri tsa boleng bo phahameng tsa lithium-ion tse li matlafatsang.Patlisiso le katoloso ya dithekenoloji tsa ho tjhaja le ho tjhaja ka potlako, mmoho le ho lelefatsa bophelo ba betri, ke mesebetsi ya bohlokwa ntshetsopeleng ya yona.
Lintlha tse 'maloa, tse kang li-interface tsa electrode-electrolyte interface, lithium ion diffusion, le electrode porosity, li ka thusa ho hlōla mathata ana le ho finyella ho tjhaja ka potlako le bophelo bo atolositsoeng.
Lilemong tse 'maloa tse fetileng, li-nanomaterials tsa mahlakore a mabeli (2D) (meaho ea maqephe a botenya ba li-nanometer tse seng kae) li hlahile e le lisebelisoa tse ka bang teng tsa anode bakeng sa libeteri tsa lithium-ion.Li-nanosheet tsena li na le sets'oants'o se phahameng sa sebaka se sebetsang le karo-karolelano e phahameng, tse tlatsetsang ho tjhajang ka potlako le litšobotsi tse ntle tsa libaesekele.
Haholo-holo, li-nanomaterials tse mahlakore a mabeli tse thehiloeng ho transition metal diborides (TDM) li ile tsa hohela tlhokomelo ea sechaba sa mahlale.Ka lebaka la lifofane tsa mahe a linotši tsa liathomo tsa boron le litšepe tse ngata tsa phetoho, li-TMD li bonts'a lebelo le phahameng le botsitso ba nako e telele ba lithium ion storage cycles.
Hona joale, sehlopha sa lipatlisiso se etelletsoeng ke Prof. Noriyoshi Matsumi oa Japane Advanced Institute of Science and Technology (JAIST) le Prof. Kabir Jasuja oa Indian Institute of Technology (IIT) Gandhinagar o sebetsa ho tsoela pele ho hlahloba ho khoneha ha polokelo ea TMD.
Sehlopha se entse thuto ea pele ea lifofane mabapi le ho boloka titanium diboride (TiB2) hierarchical nanosheets (THNS) e le lisebelisoa tsa anode bakeng sa libeteri tsa lithium-ion.Sehlopha se ne se kenyelletsa Rajashekar Badam, eo e kileng ea e-ba Morupeli e Moholo oa JAIST, Koichi Higashimin, JAIST Technical Expert, Akash Varma, seithuti sa khale sa JAIST, le Dr. Asha Lisa James, seithuti sa IIT Gandhinagar.
Lintlha tsa lipatlisiso tsa bona li phatlalalitsoe ho ACS Applied Nano Materials mme li tla fumaneha inthaneteng ka la 19 Loetse 2022.
TGNS e ile ea fumanoa ka oxidation ea TiB2 phofo e nang le hydrogen peroxide e lateloa ke centrifugation le lyophilization ea tharollo.
Se etsang hore mosebetsi oa rona o hlahelle ke scalability ea mekhoa e ntlafalitsoeng ea ho kopanya li-nanosheet tsena tsa TiB2.Ho fetola leha e le efe li-nanomaterial hore e be theknoloji e bonahalang, scalability ke eona ntho e fokotsang.Mokhoa oa rona oa maiketsetso o hloka feela pherekano ebile ha o hloke lisebelisoa tse tsoetseng pele.Sena se bakoa ke boits'oaro ba ho qhibiliha le bo bocha ba TiB2, e leng ho sibolloa ka phoso ho etsang hore mosebetsi ona e be borokho bo ts'episang ho tloha lab ho ea tšimong.
Kamora moo, bafuputsi ba ile ba theha anode lithium-ion half cell ba sebelisa THNS joalo ka anode e sebetsang 'me ba batlisisa thepa ea polokelo ea tefiso ea anode e thehiloeng ho THNS.
Bafuputsi ba ithutile hore anode e thehiloeng ho THNS e na le matla a phahameng a ho lahla a 380 mAh / g ka sekhahla sa hajoale sa 0.025 A/g feela.Ho phaella moo, ba ile ba bona matla a ho lahla a 174mAh / g ka tekanyo e phahameng ea hona joale ea 1A / g, ho boloka matla a 89.7%, le nako ea tefiso ea metsotso ea 10 ka mor'a potoloho ea 1000.
Ntle le moo, li-anode tsa lithium-ion tse thehiloeng ho THNS li khona ho mamella maqhubu a phahameng haholo, ho tloha ho 15 ho isa ho 20 A/g, ho fana ka tjhaja e potlakileng haholo ka metsotsoana e 9-14.Ka maqhubu a phahameng, ho boloka matla ho feta 80% ka mor'a lipotoloho tse 10,000.
Liphetho tsa phuputso ena li bonts'a hore li-nanosheet tsa 2D TiB2 ke batho ba loketseng ho tjhaja betri ea lithium-ion bophelo bo bolelele ka potlako.Li boetse li totobatsa melemo ea lisebelisoa tse ngata tsa nanoscale tse kang TiB2 bakeng sa thepa e ntle e kenyelletsang bokhoni bo phahameng ba lebelo, polokelo ea pseudocapacitive charge le ts'ebetso e ntle haholo ea libaesekele.
Theknoloji ena ea ho tjhaja ka potlako e ka potlakisa ho ata ha likoloi tsa motlakase le ho fokotsa haholo nako ea ho leta bakeng sa ho tjhaja lisebelisoa tse fapaneng tsa elektroniki.Re tšepa hore liphello tsa rona li tla susumetsa lipatlisiso tse eketsehileng sebakeng sena, tse ka qetellang li tlisa boiketlo ho basebelisi ba EV, ho fokotsa tšilafalo ea moea oa litoropong, le ho fokotsa khatello ea kelello e amanang le bophelo ba liselefouno, kahoo ho eketsa tlhahiso ea sechaba sa rona.
Sehlopha se lebeletse hore theknoloji ena e tsotehang e tla sebelisoa likoloing tsa motlakase le lisebelisoa tse ling tsa elektronike haufinyane.
