Bateri za sodium ion zikorwa n'iki?

Bateri za sodium-ion zikozwe mu bikoresho bisa n'ibikoreshwa muri bateri za lithium-ion, ariko hamweiyoni za sodium (Na⁺)nk'ibikoresho bitwara umuriro aho kuba lithiyumu (Li⁺). Dore isesengura ry'ibice bikoreshwa muri byo:

1. Kathode (Electrode nziza)

Aha niho iyoni za sodiyumu zibikwa mu gihe cyo gusohora.

Ibikoresho bisanzwe bya cathode:

• Okiside ya manganese ya sodiyumu (NaMnO₂)

• Fosifate y'icyuma ya sodiyumu (NaFePO₄)— bisa na LiFePO₄

• Okiside ya kobalti ya sodium nickel manganese (NaNMC)

• Ubururu bwa Prussia cyangwa Umweru wa Prussiaanalogues — ibikoresho bihendutse kandi bishyushya vuba

2. Anode (Electrode mbi)

Aha niho iyoni za sodiyumu zibikwa mu gihe cyo gushyushya.

Ibikoresho bisanzwe bya anode:

• Karuboni ikomeye— ibikoresho bya anode bikoreshwa cyane

• Aloyi zishingiye kuri Tin (Sn)

• Ibikoresho bishingiye kuri fosifore cyangwa antimoni

• Oxyde zishingiye kuri titanium (urugero, NaTi₂(PO₄)₃)

Icyitonderwa:Graphite, ikoreshwa cyane muri batiri za lithium-ion, ntabwo ikora neza na sodium bitewe n'uko ifite ionic nyinshi.

3. Electrolyte

Uburyo bworoshye butuma iyoni za sodiyumu zigenda hagati ya cathode na anode.

• Ubusanzweumunyu wa sodiyumu(nka NaPF₆, NaClO₄) yashongeshejwe mu buryoumuti w'umwimerere(nk'ibinyabutabire bya ethylene karubone (EC) na dimethyl karubone (DMC))

• Imiterere imwe n'imwe igezweho ikoreshwaelectrolyte zo mu rwego rwo hejuru

4. Igitandukanya

Uduce tw’umuyoboro dutuma anode na cathode bidakoraho ariko bigatuma iyoni itembera.

• Ubusanzwe bikorwa napolypropylene (PP) or polyethylene (PE)Imbonerahamwe y'Incamake:

Mbwira niba ushaka kugereranya bateri za sodium-ion na lithium-ion.
