Zenziwe ngantoni iibhetri ze-solid state?

Iibhetri ze-Solid-state zifana kakhulu neebhetri ze-lithium-ion, kodwa endaweni yokusebenzisa i-electrolyte engamanzi, zisebenzisa i-i-electrolyte eqinileyoIzinto eziphambili eziyinxalenye yazo zezi:

1. I-Cathode (i-Electrode Elungileyo)

• Idla ngokusekwe kwiiikhompawundi ze-lithium, efana neebhetri ze-lithium-ion zanamhlanje.

• Imizekelo:

  • I-lithium cobalt oxide (LiCoO₂)

  • I-lithium iron phosphate (LiFePO₄)

  • I-lithium nickel manganese cobalt oxide (NMC)

• Ezinye iidizayini ze-solid-state zikwahlola ii-cathodes ezine-voltage ephezulu okanye ezisekelwe kwi-sulfur.

2. I-Anode (i-Electrode engalunganga)

• Ndingayisebenzisaisinyithi se-lithium, enobunzima obukhulu kakhulu kunee-anode ze-graphite kwiibhetri zeLi-ion eziqhelekileyo.

• Ezinye izinto ezinokwenzeka:

  • Igrafayithi(njengakwiibhetri zangoku)

  • I-siliconizinto ezidityanisiweyo

  • I-lithium titanate (LTO)usetyenziso lokutshaja ngokukhawuleza

3. I-Electrolyte Eqinileyo

Lo ngumahluko ophambili. Endaweni yolwelo, i-medium ethwala ii-ion iqinile. Iintlobo eziphambili ziquka:

• Iiseramikhi(esekelwe kwi-oxide, esekelwe kwi-sulfide, uhlobo lwe-garnet, uhlobo lwe-perovskite)

• IiPolymers(iipolymers eziqinileyo ezineetyuwa ze-lithium)

• Ii-electrolytes ezidityanisiweyo(indibaniselwano yeeseramikhi kunye neepolymers)

4. Isahluli

• Kwiindlela ezininzi zoyilo lwe-solid-state, i-electrolyte eqinileyo ikwasebenza njengokwahlulahlula, ithintela ii-short circuits phakathi kwe-anode kunye ne-cathode.

Kufuphi:Iibhetri ze-Solid-state zihlala zenziwe nge-i-lithium metal okanye i-graphite anode, ai-cathode esekelwe kwi-lithium, kunyei-electrolyte eqinileyo(i-ceramic, i-polymer, okanye i-composite).
