A cewar rahotannin kafofin watsa labaru na kasashen waje, tun da silicon yana da yawan makamashi mai yawa, ya zama abu mai ban sha&39;awa na baturi anode na lithium-ion. Koyaya, a cikin lokacin caji, raguwar haɓakawa zai iya kaiwa 300% lokacin da silicon a cikin tantanin halitta ke hulɗa da lithium. Kuma bayan lokaci, zai rage yawan aiki, gajeriyar da&39;irar baturi, kuma a ƙarshe zai haifar da guntun baturi.

Domin inganta rashin amfanin da ke sama da kuma kula da yawan ƙarfin baturin, a halin yanzu ana amfani da anode na baturin lithium-ion ta amfani da silicon monoxide (SiOx, X≈1). Aikace-aikacen siliki na tushen anode yana da girma sosai, kuma an inganta aikin sake zagayowar. Duk da haka, abu har yanzu bai hana ƙarar canje-canje ba, kuma rashin ƙarfi mai rauni yana da rauni.

An gudanar da aikin bincike mai yawa don magance matsalolin fasaha na sama. A yau, ƙungiyar bincike a ƙasata da Amurka sun buga sakamakon bincike kuma sun sami sababbin hanyoyin ingantawa guda biyu. Sakamakon bincike na ƙungiyar Amurka: Non-m silica oxide / carbon hadaddun Kentucky University (UNIVERSITYE) bincike tawagar Bayan hadawa silicon-tushen oxide barbashi da kraftlignin, synthesizing wani babban yi ba bonded Silicon tushen oxide / carbon hadaddun (Binder-freesiox / c) domin yin electrodes na lithium ion baturi.

Bayan maganin zafi, lignin yana samar da jiki mai gudanarwa (ConductiveMatrix), wanda zai iya ɗaukar adadi mai yawa na ƙwayoyin oxide na tushen silicon don tabbatar da halayen lantarki, haɗin kai, da daidaitawa da halayen lithion / deodentation yayin lithation / Delithiation. Canjin girma. Wannan abu baya buƙatar yin amfani da ɗaurin ɗaure ko madugu na al&39;ada.

Ayyukan na&39;urar lantarki da aka yi da kayan haɗin gwiwar yana da kyau kwarai. Idan aka kwatanta da ƙaramin siliki-based oxide electrode (160%) na ƙimar canjin girma, kayan aikin lantarki na injina suna da kyau, ferbonmatrix babba ne, kuma ana iya daidaita shi zuwa canjin girma. Sakamakon binciken ƙungiyarmu: Micro SiOx / C Cabens (Core-Shell) Haɗa ƙungiyar bincike ta ƙasata ta samar da ingantacciyar mafita don shirya hadadden harsashi na micro SiOx / C.

Ƙungiyar binciken ta haɗu da citricacid da oxide na tushen silicon ya sanya shi carbon, sannan kuma SiOx / C-core harsashi mai laushi - SiOx micro core da citrate carbon CONFORMALCARBONSHELL. Harsashin carbon ya ƙara haɓaka ƙarfin lantarki na oxides na tushen silicon, da canjin ƙarar daidaitawa ga halayen lithiuming / deod lithium. Na&39;urorin lantarki da SiOx / C hadaddun suka yi sune 1296.

3mAh / g, kuma KYAUTA yana da girma kamar 99.8%, kuma ƙimar riƙewa shine 65.1% (843.

5mAh / g) bayan caji da fitarwa shine sau 200. A cewar ƙungiyar binciken, aikin fitarwa na hadaddun yana da matukar kyau. Hanyar na iya cimma yawan samarwa, farashi mai tsada, na iya samar da kayan aikin anode masu girma da aka yi daga hadaddun SiOx / C.
