Question

What is a disadvantage of Lithium batteries?

Answer 1

Lithium batteries

1. In the lithium batteries the Lithium-ion is moved from the negative electrode through the electrolyte solution to the positive electrode during discharge.
2. It get reversed back during charging.
3. These batteries have a high energy density, and low self-discharge.
4. The chemical equation for the Lithium batteries can be written as $$\begin{gathered} {\mathrm{LiC}}_6+{\mathrm{CoO}}_2\rightleftharpoons {\mathrm{C}}_6+{\mathrm{LiCoO}}_2 \\ \mathrm{Lithium}\mathrm{Cobalt}\mathrm{Lithium} \\ \mathrm{Carbide}\mathrm{oxide}\mathrm{cobalt}\mathrm{oxide} \end{gathered}$$
5. Discharging occurs from left to right and charging occurs right to left as it is a reversible reaction.

The disadvantage of Lithium Batteries

1. They are not robust, so they require protection.
2. They suffer from aging and thus with time they degrade.
3. They are not resistant to high temperatures.
4. They cannot be transported as they are hazardous.
