Ingaruka zo Kwishyurwa Byihuse kuri Bateri ya Litiyumu nziza ya Electrode

Porogaramu ya bateri ya lithium-ionyazamuye cyane imibereho yabantu. Ariko, hamwe niterambere ryihuse rya societe igezweho, abantu barasaba umuvuduko mwinshi kandi mwinshi, bityo ubushakashatsi kubyerekeranye no kwishyurwa byihuse bya batiri ya lithium-ion ni ngombwa cyane. Izi mbaraga-nyinshibateri ya lithium-iontekinoroji yo kwishyuza byihuse izaba ifite ibyifuzo byinshi mubikoresho bya elegitoroniki bigendanwa, ibikoresho byamashanyarazi menshi, hamwe nibinyabiziga byamashanyarazi. Nyamara, ubushakashatsi bwihuse bwo kwishyuza bwabujijwe n'inzitizi nyinshi, nka lithium ubwihindurize kuruhande rwa electrode mbi. Kugirango tunoze imikorere yihuse ya bateri ya lithium-ion, tugomba kumva neza impinduka mubikoresho bya electrode mugihe cyiza kandi kibi.

Vuba aha, Dr. Tanvir R. Tanim wo muri Amerika yasohoye inyandiko zijyanye n'ubushakashatsi. Iyi ngingo ikomatanya isesengura ryamashanyarazi, uburyo bwo kunanirwa no kuranga nyuma yo kwipimisha kugirango bige ku ngaruka zo kwishyurwa byihuse (XFC) ku bikoresho bya cathode ku munzani myinshi. Ingero zigeragezwa zirimo 41 G / NMCbateri. Igipimo cyihuse (1-9 C) no kuzenguruka inshuro 1000 muri reta ishinzwe. Byagaragaye ko mugihe cyambere cyambere, ikibazo cya electrode nziza cyari gito cyane, ariko nyuma yubuzima bwa bateri, electrode nziza yagaragaye nkibice bigaragara kandi iherekejwe nuburyo bwo kunanirwa, kunanirwa kwa electrode nziza byatangiye kwihuta. Mugihe cyizunguruka, imiterere nyamukuru ya electrode nziza ikomeza kuba ntamakemwa, ariko birashobora kugaragara ko ibice byo hejuru byahinduwe kuburyo bugaragara.

Binyuze mu isesengura, urashobora kubona ko no ku gipimo gito cyane, ubujyakuzimu bwimbitse buzatera ubushobozi bwa cathode kugabanuka. Ibi biterwa cyane cyane nuburebure bwumuriro mwinshi butera imihangayiko iterwa imbere ya electrode nziza yiyongera, bityo deformasiyo nayo iba nini, bikaviramo kwangirika kwinshi kuri buri cyiciro.
