Izinto ze-Anode ze-Pre-Lithiated SiO Ezisebenza Kakhulu 1500 mAh/g, Ukusebenza Kahle okungu-89.5%

Ukubuka konke kwe-High-Performance Pre-Lithiated SiO Anode Material

Izinto zethu ze-Pre-Lithiated Silicon Oxide (SiO) Anode Material ziwuhlobo lwe-electrode olungalungile lwesizukulwane esilandelayo lwamabhethri e-lithium-ion, akhiqizwa nge-carbon composite coating kanye ne-solid-phase lithiation ye-silicon monoxide (SiO2). Ngokungenisa imithombo ye-lithium yangaphandle ngesikhathi sokwenziwa, izigaba ezizinzile ezifana ne-lithium silicate zakhiwa ngaphakathi kwesakhiwo se-silicon-oxygen, okuqinisekisa ngempumelelo ukulahlekelwa kwe-lithium esebenzayo okungenakuguqulwa ngesikhathi somjikelezo wokuqala wokukhipha ishaja. Lokhu kuthuthukisa kakhulu ukusebenza kahle kwe-Coulombic kokuqala ngenkathi kunikeza umthamo othize okhethekile, okwenza kube yisisombululo se-anode esifanele kakhulu sezinhlelo zebhethri ezinamandla aphezulu.

Izici ze-High-Performance Pre-Lithiated SiO Anode Material

• Ukusebenza Kahle Komjikelezo Wokuqala Okuthuthukisiwe Kakhulu: Ukwelashwa kwangaphambi kokwelashwa kuphakamisa ukusebenza kahle kwe-Coulombic kokuqala kusuka ku-~70% (i-SiO evamile) kuya ku- 86% –92%, ukunciphisa ukulahlekelwa kwamandla okungenakuguqulwa kanye nokunikeza ukwesekwa okubalulekile kokuthuthukiswa kobuningi bamandla.
• Amandla Akhethekile Aphakeme: Inikeza amandla okuguqula 1500–1600 mAh/g, zisebenza kahle kakhulu kune-anode ye-graphite yendabuko ukuze kukhuliswe ubuningi bamandla ezingeni lamaseli.
• Ukuzinza Okuhle Kakhulu Kokuhamba Ngebhayisikili: Ukwembozwa kwekhabhoni engaphezulu kuvimbela ngempumelelo ukuguguleka kwe-electrolyte, kukhuthaza ukwakheka kwefilimu ye-SEI (Solid Electrolyte Interphase) ezinzile, futhi kwandise impilo yomjikelezo. Amabanga akhethiwe ayagcina >80% umthamo ngemva kwemijikelezo engaphezu kuka-1200.
• Ukusebenza Okuhle Kwezinga: Ifanele izinhlelo zokusebenza zokushaja/zokukhipha ibhethri ezisezingeni eliphezulu, ihlangabezana nezidingo zokushaja okusheshayo zamabhethri kagesi kanye nezinto zikagesi ezisetshenziswa ngabathengi. Ihambisana namabhethri e-liquid anamandla aphezulu, i-hybrid solid-state, kanye ne-all-solid-state.
• Isendlalelo Sokumboza Ikhabhoni Esinemisebenzi Emibili: Ingqimba yekhabhoni engaphezulu ayigcini nje ngokuthuthukisa ukuhanjiswa kwe-elekthronikhi futhi imelana nokuhlaselwa yi-electrolyte kodwa futhi isebenza njengendawo yokubopha ngesikhathi sangaphambi kokulungiswa, okwenza ngcono ukusebenza kwe-electrochemical kwezinto zokugcina.

Ukwakheka kwe-Slurry (Isilinganiso Sesisindo):
I-XYGY-3: I-Super P: I-CN1 Binder = 8: 1: 1

Inqubo Yokulungiselela Udaka:

1. Kala u-339 g we-CN1 binder bese ufaka ku-1161 g wamanzi acwengekile kakhulu. Hlanganisa ku-600 rpm imizuzu engu-300 kuze kube yilapho ihlakazeka ngokulinganayo.
2. Kala u-1.728 g wezinto ezisebenzayo ze-XYGY-3 kanye no-0.216 g we-Super P ebhodweni lokuxuba. Gaya kancane imizuzu eyi-10.
3. Engeza u-6.371 g wesisombululo se-CN1 esilungisiwe kusengaphambili ebhodweni bese uvala.
4. Faka i-stirrer yamagnetic imizuzu engu-360 ukuze uthole i-slurry yokugcina.
5. Gcoba i-slurry ku-foil yethusi bese womisa i-electrode engcolile ehlanganisiwe ku-80°C ngaphansi kwe-vacuum amahora ayi-12.

Iphrothokholi Yokuhlola Amaseli Ezinhlamvu Zemali (Imijikelezo Emi-3):

• Isinyathelo 1: Phumula amahora angu-6, bese ukhipha ku-0.1C kuya ku-0.005V.
• Isinyathelo 2: Phumula imizuzu emi-5, ukhiphe ku-0.02C kuya ku-0.005V.
• Isinyathelo 3: Phumula imizuzu emi-5, ukhiphe ku-0.1C kuya ku-0.005V.
• Isinyathelo 4: Phumula imizuzu emi-5, shaja ku-0.1C kuya ku-1.5V.
• Isinyathelo 5: Phumula imizuzu emi-5, buyela esinyathelweni sesi-2 bese uphinda imijikelezo emi-3.

Imibuzo Evame Ukubuzwa Yokusebenza Okuphezulu Kwezinto Ezisetshenziswa Ngaphambi Kokusebenza Kwe-SiO Anode

1. Iyini indlela ejwayelekile yokusebenza kahle kweCoulombic kwalokhu okubalulekile?
Ukusebenza kahle kokuqala kwe-Coulombic kusuka ku- 86% kuya 92%, kuye ngebanga elithile kanye nezimo zokuhlola, ngenani elijwayelekile eliqinisekisiwe ku ≥89.5%Lokhu kuyintuthuko ebalulekile kune-SiO evamile engakaqalwa (cishe ama-70%).

2. Iyini ikhono elithile eliguquguqukayo?
Izinto zinikeza amandla okuguqula 1500–1600 mAh/g, ngenani eliphansi eliqinisekisiwe le- 1350 mAh/g ekuhlolweni kwamaseli ezinhlamvu zemali.

3. Ukwembozwa kwekhabhoni kuzuzisa kanjani izinto zokwakha?
Ingqimba yekhabhoni isebenzela izinjongo ezimbili ezibalulekile: (1) ithuthukisa ukuhanjiswa kwe-elekthronikhi ukuze kusebenze kangcono izinga, kanye (2) isebenza njengesithiyo esivikelayo ekugqwaleni kwe-electrolyte, ikhuthaza ungqimba lwe-SEI oluzinzile olwandisa impilo yomjikelezo. Iphinde ivimbele ukusabela kwangaphambi kokushintsha kwe-lithiation kwezakhiwo ze-electrochemical zokugcina eziphakeme kakhulu.

4. Yiziphi izinhlobo zebhethri ezihambisana nalokhu?
Izinto ezibonakalayo ziyahambisana isilinda, isikhwama, kanye ne-prismatic imiklamo yebhethri le-lithium-ion, futhi ifanele izinhlelo zebhethri eziwuketshezi, ezihlanganisiwe, kanye nezinesimo esiqinile.

5. Kufanele kugcinwe futhi kuphathwe kanjani lokho okubalulekile?
Gcina endaweni eyomile, enomoya omuhle, futhi ugcine iphakheji ivaliwe ukuze kuvinjelwe ukungena komswakama. Ngesikhathi sokuthuthwa, gwema ukuphathwa kabi ukuze kuvinjelwe umonakalo wephakheji. Noma yikuphi okuchithekile kusuka ephaketheni eliphukile kufanele kulahlwe futhi kungabuyiselwa esitsheni.
