Ukwaziswa kweAnode kunye neCathode Material yeLithium Ion yebhetri

Ngokuphathelele ibhetri ye-lithium ion kunye nebhetri ye-lithium ion (ibhetri ye-lithium yepolymer ikwayeyebhetri ye-lithium ion), ibhetri ye-lithium ibhetri esebenzisa isinyithi se-lithium okanye i-lithium alloy njengento ye-cathode. Iimpawu zemichiza yentsimbi ye-lithium iyasebenza kakhulu, ukuze i-lithium yesinyithi idinga iimfuno ezingqongqo kakhulu kwimo engqongileyo yenkqubo yayo, ukugcinwa kunye nokusetyenziswa kwayo. Izinto ze-cathode ze-lithium ion ibhetri i-intercalated structure material ezifana nekhabhoni. Ibhetri ye-Lithium ion ikhuselekile kuba i-Li ion nje idlulisela phakathi kwe-anode kunye ne-cathode ngaphakathi kwebhetri. Ngokuphathelele ibhetri ye-lithium ion kunye Ibhetri ye-lithium polymer, i-electrolyte ye-lithium ion ibhetri yimeko yolwelo, ngelixa ibhetri ye-lithium polymer i-gel okanye i-slid state, eyenza ibhetri ikhuseleke.

Okokuqala

Igama lesayensi yebhetri ye-lithium ion yibhetri yesibini ye-lithium, enezinto ezihambelanayo ze-cathode. Ukwahluka kwibhetri ye-lithium yokuqala malunga ne-lithium njenge-electrode enye, ibhetri ye-lithium yesibini yi-electrolyte engamanzi edibanisa i-LiPF6 kunye ne-LiClO4 kwi-electrolyte ye-DMC: EC(v:v=1:1). Enye i-electrolyte inokuguqulwa, kodwa ibhetri ye-lithium yesibini iseyibhetri engamanzi.

Ngexesha lezinto zangaphakathi zebhetri ye-lithium polymer, i-electrolyte yayo yi-polymer, ngokuqhelekileyo i-electrolyte ye-gel kunye ne-electrolyte eqinile. Umzantsi Korea uye wasungula ibhetri yejeli ene-PEO-ion njenge-electrolyte. Ayaziwa ukuba kukho olu hlobo lwebhetri kwi-GalaxyRound okanye i-LGGFlex.

Okwesibini

Kukho umahluko phakathi kwebhetri ye-lithium polymer kunye nebhetri ye-lithium. Ibhetri ye-lithium ine-package yentsimbi ye-shell (18650 okanye i-2320), ngelixa ibhetri ye-lithium yepolymer ihlanganiswe nefilimu yokupakisha ye-aluminium, ebizwa ngokuba yi-pouch cell.

Enye ibhetri ye-lithium ine-electrolyte eyomeleleyo iyonke, njenge-LiPON, i-NASICON, i-perovskite, i-LiSICON, i-electrolyte ye-ceramic ene-conductivity ephezulu okanye i-electrolyte yeglasi eyenziwe yinto e-amorphous. Isenokuba yeyebhetri yesibini ye-lithium.

Kukho konke, ibhetri ye-lithium inokwahlulwa ibe ngamacandelo amabini: ibhetri yensimbi ye-lithium kunye nebhetri ye-lithium ion. Ngokuqhelekileyo, ibhetri yensimbi ye-lithium ayinakutshajwa kwakhona nge-metallic lithium, ngelixa ibhetri ye-lithium ion ayinayo i-metallic lithium kodwa iyatshajwa. Ibhetri ye-lithium, ibhetri ye-lithium ion kunye nebhetri ye-lithium polymer inomahluko wethiyori.
