Ngaba iibhetri eziqinileyo ziyachaphazeleka ngumkhuhlane?

indlela ukubanda okuchaphazela ngayo iibhetri ze-solid-statekwaye kwenziwa ntoni ngayo:

Kutheni ukubanda kuyingxaki

1. Ukuqhuba kwe-ionic ephantsi

   • Ii-electrolytes eziqinileyo (iiseramikhi, iisulfide, iipolymers) zixhomekeke kwii-ion ze-lithium ezitsiba kwizakhiwo zekristale eziqinileyo okanye iipolymer.

   • Kumaqondo obushushu aphantsi, oku kutsiba kuyehla, ngoko keukuxhathisa kwangaphakathi kuyandakunye nokwehla kokuhanjiswa kwamandla.

2. Iingxaki zojongano

   • Kwibhetri ekwimeko eqinileyo, unxibelelwano phakathi kwe-electrolyte eqinileyo kunye nee-electrodes lubalulekile.

   • Amaqondo obushushu abandayo anokunciphisa izinto ngesantya esahlukeneyo, nto leyo edalaizikhewu ezincincikwiindawo zonxibelelwano → okwenza ukuhamba kwee-ion kube kubi ngakumbi.

3. Ubunzima bokutshaja

   • Njengeebhetri ze-lithium-ion ezingamanzi, ukutshaja kumaqondo obushushu aphantsi kakhulu kuyingoziiplati ye-lithium(i-lithium yesinyithi eyenzeka kwi-anode).

   • Kwimeko eqinileyo, oku kunokuba yingozi nangakumbi kuba ii-dendrites (iidiphozithi ze-lithium ezifana nenaliti) zinokuqhekeza i-electrolyte eqinileyo.

Xa kuthelekiswa ne-lithium-ion eqhelekileyo

• I-lithium-ion ye-electrolyte engamanzi: Ukubanda kwenza ulwelo lube lutyebile (lungahambisi kakhulu), kunciphisa ububanzi kunye nesantya sokutshaja.

• I-lithium-ion yesimo esiqinileyo: Kukhuselekile xa kubanda (akukho manzi aqandisayo/avuzayo), kodwaisalahlekelwa kukuqhubakuba izinto eziqinileyo azithuthi kakuhle ii-ions xa kushushu kakhulu.

Izisombululo ezikhoyo kuphando

1. Ii-electrolytes ze-sulfide

   • Ezinye ii-electrolytes eziqinileyo ezisekelwe kwi-sulfide zigcina umbane ophezulu nangaphantsi kwe-0 °C.

   • Ithembisa ii-EV kwiindawo ezibandayo.

2. Ii-hybrids ze-polymer-ceramic

   • Ukudibanisa iipolymers eziguquguqukayo kunye namaqhekeza e-ceramic kuphucula ukuhamba kwee-ion kumaqondo obushushu aphantsi ngelixa kugcinwa ukhuseleko.

3. Ubunjineli bojongano

   • Kuphuhliswa ii-coating okanye ii-buffer layers ukuze kugcinwe unxibelelwano lwe-electrode-electrolyte luzinzile ngexesha lokutshintsha kobushushu.

4. Iinkqubo zokufudumeza kwangaphambili kwii-EV

   • Njengokuba ii-EV zanamhlanje zifudumeza iibhetri ezingamanzi ngaphambi kokuba zitshajwe, ii-EV zexesha elizayo ezisemgangathweni zingasebenzisaulawulo lobushushuukugcina iiseli zikwinqanaba lazo elifanelekileyo (15–35 °C).

Isishwankathelo:
Iibhetri ze-Solid-state zichaphazeleka kukubanda, ikakhulu ngenxa yokuncipha kokuqhuba kwee-ion kunye nokumelana ne-interface. Zisakhuselekile kune-lithium-ion engamanzi kwezo meko, kodwaukusebenza (ububanzi, izinga lokutshaja, amandla okukhupha) kunokwehla kakhulu ngaphantsi kwe-0 °CAbaphandi basebenza ngenkuthalo kwii-electrolytes kunye noyilo oluhlala luqhuba kakuhle emakhazeni, bejolise ekusetyenzisweni okuthembekileyo kwii-EVs nakwiimozulu zasebusika.
