Ho ea ka litlaleho tsa mecha ea litaba ea kantle ho naha, kaha silicon e na le matla a mangata a matla, e fetohile ntho e ntle haholo ea lithium-ion battery anode material. Leha ho le joalo, nakong ea ho tjhaja, shrinkage ea ho atolosa e ka fihla ho 300% ha silicon e ka seleng e sebelisana le lithium. &39;Me ha nako e ntse e ea, e tla fokotsa haholo ts&39;ebetso, potoloho e khutšoanyane ea betri,&39; me qetellong e lebise ho sekheo sa betri.

E le ho ntlafatsa mefokolo e ka holimo le ka kakaretso ho boloka matla a matla a betri, anode ea betri ea lithium-ion e sebelisoa hona joale ho sebelisoa silicon monoxide (SiOx, X≈1). Ts&39;ebeliso ea silicon-based oxide anode e phahame haholo, mme ts&39;ebetso ea potoloho le eona e ntlafalitsoe. Leha ho le joalo, thepa e ntse e sa thibele liphetoho tsa molumo, &39;me conductivity e fokolang e fokola.

Palo e kholo ea mosebetsi oa lipatlisiso e entsoe ho sebetsana le mathata a ka holimo a theknoloji. Kajeno, sehlopha sa lipatlisiso naheng ea heso le United States se phatlalalitse liphetho tsa lipatlisiso mme se fumane mekhoa e &39;meli e mecha ea ntlafatso. Liphetho tsa lipatlisiso tsa sehlopha sa US: Non-adhesive silica oxide / carbon complex Kentucky University (UNIVERSITYE) sehlopha sa lipatlisiso Ka mor&39;a ho kopanya likaroloana tsa silicon-based oxide le kraftlignin, ho kopanya ts&39;ebetso e phahameng e sa kopanngoeng ke Silicon-based oxide / carbon complex (Binder-freesiox / c) bakeng sa ho etsa li-electrode tsa libeteri tsa lithium ion.

Kamora kalafo ea mocheso, lignin e theha &39;mele oa conductive (ConductiveMatrix), o ka amohelang palo e kholo ea likaroloana tsa silicon-based oxide ho netefatsa hore ho na le elektroniki, khokahano, le ho ikamahanya le karabelo ea lithiation / deodentation nakong ea lithiation / Delithiation. Ho fetoha ha molumo. Boitsebiso bona ha bo hloke ho sebelisa li-binders tse tloaelehileng kapa li-conductors.

Ts&39;ebetso ea electrode e entsoeng ka thepa e kopantsoeng e ntle haholo. Ha ho bapisoa le silicon-based oxide electrode e batlang e le nyane (160%) ea sekhahla sa phetoho ea molumo, thepa ea mochini oa electrochemical e ntle haholo, ferbonmatrix e kholo, &39;me e ka ikamahanya le liphetoho tsa molumo. Liphetho tsa lipatlisiso tsa sehlopha sa rona: Micro SiOx / C Cabens (Core-Shell) Sehlopha sa bafuputsi sa naha ea heso se kopane se hlahisitse tharollo e sebetsang ea ho lokisa micro SiOx / C core shell complex.

Sehlopha sa boithuto se tsoakile citricacid le bolo e sila silicon-based oxide e entse carbon, e lateloa ke textured SiOx / C-core shell complex - SiOx micro core le citrate carbon CONFORMALCARBONSHELL. Khaketla ea khabone e ekelitse haholo tšebetso ea motlakase ea silicon-based oxides, le phetoho ea molumo ho ikamahanya le lithiuming / deod lithium reaction. Li-electrode tse entsoeng ke SiOx / C complex ke 1296.

3mAh / g, mme COMBICEFFICIENCY e phahame joalo ka 99.8%, mme sekhahla sa ho boloka matla ke 65.1% (843.

5mAh / g) ka mor&39;a tefiso le ho tsoa ke makhetlo a 200. Ho ea ka sehlopha sa lipatlisiso, ts&39;ebetso ea ho tsoa ha e rarahaneng e ntle haholo. Mokhoa ona o ka finyella tlhahiso ea bongata, e theko e tlaase, e ka hlahisa lisebelisoa tse phahameng tsa anode tse entsoeng ka metsoako e rarahaneng ea SiOx / C.
