He paʻakikī ka hoʻonui ʻana i ka mea hoʻonui i ka lithium battery anode i ke ala hou o ka hui ʻo ʻAmelika Hui Pū ʻIa a me Kina R <000000> D.

Wahi a nā hōʻike pāpaʻi haole, ʻoiai he kiʻekiʻe ka ikehu kiʻekiʻe o ke silika, ua lilo ia i mea hoʻohiwahiwa lithium-ion pākaukau anode. Eia nō naʻe, i ka manawa hoʻopiʻi, hiki i ka hoʻonui ʻana ke hiki i ka 300% i ka wā e launa pū ai ka silicon i loko o ke kelepona me ka lithium. A i ka hala ʻana o ka manawa, e hōʻemi nui ia i ka hana, pōkole pōkole o ka pākaukau, a i ka hopena e alakaʻi i ka ʻōpala pākaukau.

No ka hoʻomaikaʻi ʻana i nā hemahema i luna a mālama mau i ka nui o ka ikehu o ka pākaukau, hoʻohana ʻia ka anode o kahi pākahi lithium-ion me ka silicon monoxide (SiOx, X≈1). He kiʻekiʻe loa ka hoʻohana ʻana o ka anode oxide e pili ana i ka silicon, a ua hoʻomaikaʻi ʻia ka hana pōʻai. Eia nō naʻe, ʻaʻole pale ka mea i nā loli leo, a nāwaliwali ka conductivity.

Ua hana ʻia kahi helu nui o nā hana noiʻi no ka hoʻoponopono ʻana i nā pilikia ʻenehana i luna. I kēia lā, ua paʻi ka hui noiʻi ma koʻu ʻāina a me ʻAmelika i nā hopena noiʻi a loaʻa i ʻelua mau ala hoʻomaikaʻi hou. ʻO nā hualoaʻa noiʻi o ka hui US: Non-adhesive silica oxide / carbon complex Kentucky University (UNIVERSITYE) hui noiʻi Ma hope o ka hui ʻana i nā ʻāpana oxide a me ka kraftlignin, synthesizing i kahi hana kiʻekiʻe i hoʻopaʻa ʻole ʻia ʻo Silicon-based oxide / carbon complex (Binder-freesiox / c) no ka hana ʻana i nā electrodes o nā pā lithium ion.

Ma hope o ka mālama ʻana i ka wela, hoʻokumu ka lignin i kahi kino conductive (ConductiveMatrix), hiki ke hoʻokipa i ka nui o nā ʻāpana oxide i hoʻokumu ʻia i ka silicon no ka hōʻoia ʻana i ka uila uila, hoʻohui, a hoʻololi i ka hopena lithiation / deodentation i ka wā o ka lithiation / Delithiation. Hoʻololi leo. ʻAʻole pono kēia mea e hoʻohana i nā mea hoʻopili maʻamau a i ʻole conductors.

ʻO ka hana ʻana o ka electrode i hana ʻia me ka mea i hoʻohui ʻia he mea maikaʻi loa. Hoʻohālikelike ʻia me ka liʻiliʻi liʻiliʻi o ka oxide electrode (160%) o ka nui o ka hoʻololi ʻana i ka leo, maikaʻi nā waiwai electrochemical mechanical, nui ka ferbonmatrix, a hiki ke hoʻololi ʻia i nā loli leo. Nā hualoaʻa o kā mākou hui noiʻi: Micro SiOx / C Cabens (Core-Shell) Composite Ua hoʻomohala ka hui noiʻi o koʻu ʻāina i kahi hoʻonā kūpono e hoʻomākaukau ai i kahi micro SiOx / C core shell complex.

ʻO ka hui aʻo i hui pū ʻia me ka citricacid a me ka oxide e hoʻoheheʻe ʻia ana i ka pōʻai kinikini i hana ʻia he kalapona, a ukali ʻia e kahi paʻakikī SiOx / C-core pūpū - SiOx micro core a me citrate carbon CONFORMALCARBONSHELL. Ua hoʻonui nui ka pūpū kalapona i ka conductivity uila o nā oxides-based silicon, a me ka hoʻololi ʻana o ka leo i ka hoʻololi ʻana i ka hopena lithiuming / deod lithium. ʻO nā electrodes i hana ʻia e ka SiOx / C complex he 1296.

3mAh / g, a ʻo COMBICEFFICIENCY ka kiʻekiʻe e like me 99.8%, a ʻo ka nui o ka paʻa ʻana he 65.1% (843.

5mAh / g) ma hope o ka hoʻopiʻi a me ka hoʻokuʻu ʻana he 200 mau manawa. Wahi a ka hui noiʻi, maikaʻi loa ka hoʻokuʻu ʻana o ka paʻakikī. Hiki i ke ala ke hoʻokō i ka hana nui, ke kumu kūʻai, hiki ke hana i nā mea anode kiʻekiʻe i hana ʻia mai SiOx / C complex composites.
