Nigute wazamura umutekano wa bateri ya lithium

Ibyiza byimodoka nshya zingufu nuko zifite karubone nkeya kandi zangiza ibidukikije kuruta ibinyabiziga bikomoka kuri lisansi. Ikoresha ibicanwa bidasanzwe nkibikoresho bitanga ingufu, nka bateri ya lithium, lisansi ya hydrogène, nibindi. Gukoresha bateri ya lithium-ion nayo ni nini cyane, usibye ibinyabiziga bishya byingufu, terefone ngendanwa, mudasobwa zigendanwa, PC zigendanwa, ingufu zigendanwa, amagare y’amashanyarazi. , ibikoresho by'amashanyarazi, n'ibindi.

Nyamara, umutekano wa bateri ya lithium-ion ntugomba gusuzugurwa. Impanuka zitari nke zerekana ko iyo abantu bishyuye nabi, cyangwa ubushyuhe bwibidukikije buri hejuru cyane, biroroshye cyane gukurura bateri ya lithium-ion yaka umuriro, guturika, bikaba byarabaye ububabare bukomeye mugutezimbere bateri ya lithium-ion.

Nubwo imiterere ya batiri ya lithium ubwayo igena ibizaba "byaka kandi biturika", ariko ntibishoboka rwose kugabanya ingaruka numutekano. Hamwe niterambere ryiterambere rya tekinoroji ya batiri, amasosiyete ya terefone ngendanwa hamwe n’amasosiyete mashya y’ibinyabiziga bitanga ingufu, binyuze muri sisitemu yo gucunga neza bateri hamwe na sisitemu yo gucunga amashyuza, bateri izashobora kurinda umutekano, kandi ntizaturika cyangwa ibintu bitwika.

1.Gutezimbere umutekano wa electrolyte

Hariho reaction nyinshi hagati ya electrolyte na electrode nziza kandi mbi, cyane cyane mubushyuhe bwinshi. Kunoza umutekano wa bateri, kuzamura umutekano wa electrolyte nimwe muburyo bwiza. Mugushyiramo inyongeramusaruro ikora, ukoresheje umunyu mushya wa lithium no gukoresha ibishashara bishya, ingaruka z'umutekano wa electrolyte zirashobora gukemurwa neza.

Ukurikije imirimo itandukanye yinyongeramusaruro, zirashobora kugabanywamo ibyiciro bikurikira: inyongeramusaruro zo kurinda umutekano, inyongera zikora firime, inyongeramusaruro zo gukingira cathode, inyongeramusaruro yumunyu wa lithium, inyongeramusaruro yimvura ya lithium, inyongeramusaruro y’amazi arwanya ruswa, inyongeramusaruro ziyongera. , n'ibindi.

2. Kunoza umutekano wibikoresho bya electrode

Litiyumu y'icyuma ya fosifate hamwe na ternary yibigize bifatwa nkigiciro gito, "umutekano mwiza" ibikoresho bya cathode bifite ubushobozi bwo gukoreshwa cyane mubikorwa byimodoka zikoresha amashanyarazi. Kubikoresho bya cathode, uburyo busanzwe bwo kuzamura umutekano wabwo ni uguhindura impuzu, nka okiside yicyuma hejuru yibikoresho bya cathode, irashobora gukumira itumanaho ritaziguye hagati yibikoresho bya cathode na electrolyte, bikabuza ihinduka ryibintu bya cathode, kunoza imiterere yabyo ituze, gabanya ihungabana rya cations muri lattice, kugirango ugabanye umusaruro ushushe.

Ibikoresho bibi bya electrode, kubera ko ubuso bwayo bukunze kuba igice cya batiri ya lithium-ion ishobora kwibasirwa cyane no kubora kwa termo-chimique na exotherm, kuzamura ubushyuhe bwumuriro wa firime ya SEI nuburyo bwingenzi bwo kuzamura umutekano wibintu bibi bya electrode. Ubushyuhe bwumuriro bwibikoresho bya anode burashobora kunozwa na okiside nkeya, ibyuma hamwe nicyuma cya okiside, polymer cyangwa karuboni.

3. Kunoza igishushanyo mbonera cyo kurinda umutekano wa bateri

Usibye kunoza umutekano wibikoresho bya batiri, ingamba nyinshi zo kurinda umutekano zikoreshwa muri bateri yubucuruzi ya lithium-ion, nko gushyiraho ububiko bwumutekano wa bateri, feri zishushe zishushe, guhuza ibice hamwe na coefficient nziza yubushyuhe bikurikiranye, ukoresheje diafragma zifunze ubushyuhe, zipakurura uburinzi bwihariye imirongo, hamwe na sisitemu yo gucunga bateri yabigenewe, nuburyo bwo kongera umutekano.
