Cov roj teeb hauv lub xeev yog dab tsi?

Cov roj teeb hauv lub xeev zoo ib yam li lub tswv yim rau cov roj teeb lithium-ion, tab sis tsis yog siv cov kua electrolyte, lawv siv ib qhokhoom electrolyte. Lawv lub ntsiab tseem ceeb yog:

1. Cathode (zoo electrode)

• Feem ntau raws lilithium compounds, zoo ib yam li cov roj teeb lithium-ion niaj hnub no.

• Piv txwv:

  • Lithium cobalt oxide (LiCoO₂)

  • Lithium hlau phosphate (LiFePO₄)

  • Lithium nickel manganese cobalt oxide (NMC)

• Qee cov qauv tsim hauv lub xeev kuj tseem tshawb nrhiav cov hluav taws xob siab lossis cov sulfur-based cathodes.

2. Anode (tsis zoo electrode)

• Yuav siv taulithium hlau, uas muaj zog ntau dua li graphite anodes hauv cov roj teeb Li-ion li qub.

• Lwm yam muaj peev xwm:

  • Graphite(zoo li cov roj teeb tam sim no)

  • Siliconsib xyaw

  • Lithium titanate (LTO)rau kev them nyiaj ceev ceev

3. Khoom Electrolyte

Qhov no yog qhov sib txawv tseem ceeb. Hloov cov kua, qhov nruab nrab ion-carrying yog khoom. Cov hom tseem ceeb muaj xws li:

• Ceramics(Oxide-based, sulfide-based, garnet-type, perovskite-type)

• Polymers(cov khoom polymers nrog lithium ntsev)

• Composite electrolytes(kev sib xyaw ntawm ceramics thiab polymers)

4. Separator

• Hauv ntau lub xeev tsim qauv, cov khoom siv electrolyte kuj ua raws li qhov sib cais, tiv thaiv luv luv ntawm cov anode thiab cathode.

Hauv luv luv:Solid-state roj teeb feem ntau yog ua los ntawm alithium hlau los yog graphite anode, alithium-raws li cathode, thiab akhoom electrolyte(ceramic, polymer, los yog composite).
