Ngaba ukubola kwenyukliya kwebhetri ye-lithium ye-ternary akunakuphepheka ngokwenene?
Izinga lokubola kweekhompawundi ze-ternary alinakuguqulwa. Apha, kusafuneka siqale kwisakhiwo sebhetri. Iibhetri ze-lithium ze-ternary zisebenzisa iipolymers ze-ternary, kuquka i-nickel, i-cobalt, kunye ne-manganese (okanye i-aluminium) njengezinto ze-cathode. Ngokomgaqo osebenzayo we-ternary lithium ibhetri, xa ibhetri ihlawuliswa, idatha ye-lithium ion kwi-electrode efanelekileyo iphuma kwi-electrode efanelekileyo kwaye ingena kwi-graphite ye-electrode engafanelekanga nge-gap; I-lithium ion iphunyuka kwi-anode graphite kwaye ibuyele kwidatha ye-anode ngokusebenzisa isithuba.
Ngenkqubela phambili yentlawulo kunye nenkqubo yokukhupha, i-lithium ion ifakwe ngokuqhubekayo kwaye ikhutshwe kwi-electrodes efanelekileyo kunye nebi. Ukuthatha ibhetri njengomzekelo, xa amandla ephelile, umjikelo wokutshaja ugqityiwe ngexesha lenkqubo yokutshaja, okubangela ukuphelelwa amandla kwebhetri. Ngokomzekelo, ubomi bomjikelezo we-ternary lithium ibhetri malunga namaxesha angama-1,000. Xa ibhetri isetyenziswe kube kanye, ubomi bebhetri bubonke bucuthwa ngexesha elinye, kushiyeke amaxesha angama-999. Ngokomzekelo, emva komjikelezo ngamnye, ibhetri iya kubola, engenakuguquleka.
Ngokomzekelo, i-electrolyte yangaphakathi iya kubola ukuya kwinqanaba elithile. Xa idatha yomsebenzi we-electrode kwibhetri ingasebenzi, isakhiwo esihle kunye nesibi sebhetri siya kutshatyalaliswa, okubangela ukunciphisa inani le-lithium ion embedding kunye ne-de-embedding.
Ubume bebhetri ngokubanzi, kunye nokusetyenziswa kwangempela kwebhetri, ukuba ibhetri inokwenza kuphela imijikelezo ye-1000 yokutshaja kunye nokukhupha, ukutshaja kunye nokukhupha imijikelezo, umthamo webhetri yepakethi uya kubonakala uncitshisiwe. Ngokomgama wokuqhuba, oko kukuthi, inokuqhuba kuphela ngentlawulo epheleleyo. Umgama ukuya kwindawo yokuqala. Ekubeni ukubola kwebhetri kungenakuguqulwa, ukubonakala kwe-appendix kunokutshintshwa kuphela kwibhetri.
