Halaye da yanayin aikace-aikace na batirin sodium ion

Haɗa ma’auni na fasaha masu dacewa na batirin ion sodium ion da Zhongke Hainer da Ningde Times suka fitar, za mu iya nazarin yanayin aikace-aikacen al’ada na sodium ion.

1. Kasuwar ajiyar wutar lantarki
Bayan manyan-sikelin masana’antu na sodium-ion baturi, kudin ne mafi m fiye da na lithium-ion baturi, da kuma sake zagayowar rayuwa na iya zama fiye da 6000 sau, da kuma sabis rayuwa na iya zama har tsawon shekaru 10 zuwa 20. wanda ya dace musamman ga kololuwa da kwarin ajiyar makamashin lantarki. Daidaita kuma santsi hawa da sauka.

Bugu da ƙari, fa’idodin haɓakawa mai girma, haɗe tare da fa’idodin ƙarancin farashi, yin batir sodium ion musamman dacewa da buƙatun aikace-aikacen grid mitar gyare-gyare.

A hade, batir sodium-ion na iya kusan rufe buƙatun aikace-aikace daban-daban a fagen ajiyar makamashin lantarki, gami da bangaren samar da wutar lantarki, gefen grid, da gefen mai amfani, gami da kashe-grid, haɗin grid, daidaitawar mitar, kololuwar aski. , ajiyar makamashi, da dai sauransu.

2. Kasuwar abin hawa lantarki mai haske
Ƙananan fa’idar batir sodium-ion da halayen kariyar muhalli sun sa ya zama mafi yuwuwar maye gurbin batirin acid-acid kuma ya zama babban aikace-aikacen kasuwar motocin lantarki mai haske.

Kamar yadda kowa ya sani, saboda ƙarancin farashinsa, baturan gubar-acid sun kasance zaɓi na farko na masu taya biyu masu amfani da wutar lantarki, masu keken lantarki, da ƙananan keken lantarki masu ƙafa huɗu. Sai dai kuma saboda gurbatar dalma, kasar na ci gaba da inganta amfani da batura masu sinadari da ba su dace da muhalli ba domin maye gurbin batir-acid. Batura, batir ion sodium babu shakka madadin kyakkyawan zaɓi ne, ana tsammanin cimma kusan farashin batirin gubar-acid, amma aikin yana gaban batirin gubar-acid.

3. Yankin sanyi tare da ƙananan zafin jiki
A cikin manyan latitudes, mafi ƙarancin zafin jiki a lokacin hunturu na iya kaiwa sau da yawa ya rage 30 ° C, kuma ƙananan yanayin zafi ma ya fi ƙasa da 40 ° C, wanda ke haifar da babban kalubale ga batir lithium.

Tsarin kayan baturi na lithium da ke akwai, ko dai baturin lithium titanate, ko baturin lithium na ternary ko lithium iron phosphate baturi tare da ingantaccen yanayin zafi, kuma ana iya amfani da shi zuwa yanayin da bai wuce 40 ° C ba, amma farashin yana da tsada sosai. .
