Bateri zikomeye za leta ziterwa nubukonje?

burya ubukonje bugira ingaruka kuri bateri zikomeyen'ibiri gukorwa kuri yo:

Kuki ubukonje ari ikibazo

1. Umuyoboro muto wa ionic

   • Electrolytite ikomeye (ceramics, sulfide, polymers) yishingikiriza kuri ioni ya lithium igenda inyura muri kristu ikomeye cyangwa polymer.

   • Ku bushyuhe buke, uku gutinda gutinda, bityoimbere imbere biriyongerano gutanga amashanyarazi biragabanuka.

2. Ibibazo by'imbere

   • Muri bateri-ikomeye, guhuza hagati ya electrolyte ikomeye na electrode ni ngombwa.

   • Ubushyuhe bukonje burashobora kugabanya ibikoresho kubiciro bitandukanye, kuremamicro-icyuhokuri interineti → gutuma ion itemba nabi.

3. Kwishyuza ingorane

   • Nka bateri ya lithium-ion yuzuye, kwishyuza ubushyuhe buke cyaneisahani(lithium metallic ikora kuri anode).

   • Muburyo bukomeye, ibi birashobora no kwangiza cyane kubera ko dendrite (kubitsa inshinge zimeze nka lithium) zishobora kumena electrolyte ikomeye.

Ugereranije na lithium-ion isanzwe

• Amazi ya electrolyte lithium-ion: Ubukonje butuma amazi yiyongera (atayobora neza), agabanya intera n'umuvuduko wo kwishyuza.

• Lithium-ion ikomeye: Umutekano mukonje (nta gukonjesha / gutemba), arikoaracyatakaza ubushobozikuberako ibinini bidatwara ion neza kuri temps nkeya.

Ibisubizo bigezweho mubushakashatsi

1. Sulfide electrolytes

   • Sulfide ishingiye kuri electrolytite ikomeye igumana umuvuduko mwinshi ndetse no munsi ya 0 ° C.

   • Gusezerana kuri EV mu turere dukonje.

2. Polymer - ceramic hybrid

   • Gukomatanya polimeri yoroheje hamwe nuduce twa ceramic biteza imbere ion gutemba mugihe gito kandi bikomeza umutekano.

3. Ubwubatsi bwa interineti

   • Ipitingi cyangwa buffer zirimo gutezwa imbere kugirango electrode - electrolyte ihure neza mugihe cy'ubushyuhe.

4. Sisitemu yo gushyushya mbere muri EV

   • Nkuko EVS zubu zishyushya bateri zamazi mbere yo kwishyuza, ejo hazaza hameze nezagucunga ubushyuhekugumisha selile murwego rwiza (15-35 ° C).

Incamake:
Batteri ikomeye cyane yibasiwe nubukonje, cyane cyane bitewe nubushobozi buke bwa ion hamwe no kurwanya interineti. Baracyafite umutekano kuruta lithium-ion y'amazi muri ibyo bihe, arikoimikorere (intera, igipimo cyamafaranga, ingufu zisohoka) irashobora kugabanuka cyane munsi ya 0 ° C.. Abashakashatsi barimo gukora cyane kuri electrolytite n'ibishushanyo bikomeza kuyobora mu mbeho, bagamije gukoresha neza muri EV ndetse no mu bihe by'imbeho.
