Sodium-ion da lithium-ion baturi

Sodium ion baturi: Batir sodium ion wani nau’in baturi ne na sakandare (batir mai caji), wanda ya dogara kacokan akan motsin ions sodium tsakanin ingantattun lantarki da na’urori marasa kyau don aiki, kama da tsarin aiki na baturin lithium ion. A lokacin caji da fitarwa, Na + yana ciki kuma yana raguwa a baya da baya tsakanin nau’ikan lantarki guda biyu: lokacin caji, Na+ yana cirewa daga ingantacciyar wutar lantarki kuma an saka shi a cikin mummunan lantarki ta hanyar electrolyte; lokacin fitar da wuta, akasin haka.

Mafi mahimmancin fasalin batirin ion sodium shine amfani da Na+ maimakon tsada Li+, don haka kayan cathode, kayan cathode da electrolyte dole ne a canza su daidai don dacewa da batirin Na ion. Idan aka kwatanta da lithium, sodium yana da yawa a cikin ɓawon burodi na ƙasa kuma hanyar samun Na abu ne mai sauƙi, don haka idan aka kwatanta da baturan lithium ion, batir sodium ion za su sami fa’ida ta fuskar farashi.

Babban wahalar batirin ion sodium shine samun ingantaccen abu na anode don batirin ion sodium. Graphite, kayan gargajiya na anode na baturin lithium ion, na iya haɗawa tare da Li don samar da fili na tsarin LiC6 tare da ƙayyadaddun ƙayyadaddun iya aiki na 372mAh/g, amma graphite zai iya adana iyakataccen adadin Na ions, wanda na iya zama saboda gaskiyar cewa Na zai fara samar da shafi a saman graphite maimakon samar da fili tare da graphite. fili.

Duk da cewa karfin kuzarin batirin ion sodium bai kai na batirin lithium ion ba, amma saboda dimbin albarkatun Na, kuma da saukin samu, hade da tsadar lithium carbonate na yanzu, don haka a cikin dogon lokaci. Na ion baturi har yanzu yana da fa’idan kewayon aikace-aikace bege, a wasu yankunan da ba ya bukatar high makamashi yawa, kamar ikon grid makamashi ajiya, peaking, iska ikon ajiya, da dai sauransu har yanzu yana da aikace-aikace begen.
