Dị ka akụkọ mgbasa ozi si mba ọzọ si kwuo, ebe ọ bụ na silicon nwere ike dị elu, ọ ghọọla ihe anode batrị lithium-ion mara mma nke ukwuu. Otú ọ dị, n&39;ime oge nchaji, mgbasawanye mgbasa nwere ike iru 300% mgbe silicon na cell na-emekọrịta ihe na lithium. Na ka oge na-aga, ọ ga-ebelata arụmọrụ nke batrị, obere sekit nke batrị, na n&39;ikpeazụ na-eduga na nkwụsị batrị.

Iji meziwanye adịghị ike ndị a dị n&39;elu ma na-echekwa njupụta ike nke batrị ahụ, anode nke batrị lithium-ion na-arụ ọrụ ugbu a site na iji silicon monoxide (SiOx, X≈1). Ngwa nke silicon oxide anode dị elu nke ukwuu, na-arụkwa ọrụ okirikiri. Otú ọ dị, ihe ka na-adịghị egbochi mgbanwe olu, na adịghị ike conductivity adịghị ike.

Emeela ọtụtụ ọrụ nyocha iji dozie nsogbu teknụzụ dị n&39;elu. Taa, ndị otu nyocha na obodo m na United States ebipụtala nsonaazụ nyocha wee chọpụta ụzọ nkwalite abụọ ọhụrụ. The nnyocha pụta nke US otu: Non-nrapado silica oxide / carbon complex Kentucky University (UNIVERSITYE) nnyocha otu Mgbe agwakọta silicon dabeere oxide ahụ na kraftlignin, synthesizing a elu arụmọrụ na-abụghị bonded Silicon dabeere oxide / carbon mgbagwoju (Binder-freesiox / c) maka ime electrodes nke lithium ion batrị.

Mgbe ọgwụgwọ okpomọkụ gasịrị, lignin na-etolite ahụ na-eduzi (ConductiveMatrix), nke nwere ike nabata ọnụ ọgụgụ dị ukwuu nke ihe ndị dị na silicon iji hụ na eletrọnịkị, njikọta, na ime mgbanwe na mmeghachi omume lithiation / deodentation n&39;oge lithiation / Delithiation. Mgbanwe olu. Ihe a na-adịghị mkpa iji ihe nkedo ma ọ bụ ndị nduzi.

Arụmọrụ nke electrode mere nke ihe mejupụtara ihe dị nnọọ mma. E jiri ya tụnyere obere silicon oxide electrode (160%) nke ọnụego mgbanwe olu, akụrụngwa electrochemical dị oke mma, ferbonmatrix buru ibu, enwere ike ịmegharị ya na mgbanwe olu. Nsonaazụ nke nyocha otu anyị: Micro SiOx / C Cabens (Core-Shell) mejupụtara ndị otu nyocha nke obodo m mepụtara ihe ngwọta dị mma iji kwadebe ihe mgbagwoju anya micro SiOx / C.
