Question

hm can someone simply explain how a lithium ion battery works?

Answer 1

when the cell is discharing, the lithium ions move from -ve electrode to +ve electrode. When the cell is charging, they moves to the -ve electrode from the +ve electrode.

the -ve electrode of a conventional lithium-ion rechargeable cell is made from lithium carbon compound LixC6. the +ve electrode is a metal oxide (eg, CoO2, MnO2, or NiO2).
the chemical eqns are
+ve electrode:
(discharging)
\[CoO _{2} + xLi ^{+} +xe ^{-} \rightarrow Li _{x}CoO_{2}\] Charging:
\[CoO _{2} + xLi ^{+} +xe ^{-} \leftarrow Li _{x}CoO_{2}\] -ve electrode:
Dischariging:
\[Li _{x}C _{6} \rightarrow 6C+xLi ^{+}+xe ^{-}\]Charging:
\[Li _{x}C _{6} \leftarrow 6C+xLi ^{+}+xe ^{-}\]
hmm.. just copy from the chemistry book...

Answer 2

nice ans
