Consider the following differences between Lithium-ion battery and Ni-Cd battery:

Lithium-ion battery is smaller in size and requires low maintenance than Ni-Cd battery

Lithium-ion battery is environmentally safer than Nickel-cadmium battery

Which of the above statements is/are correct?

Question

Lithium-ion battery is smaller in size and requires low maintenance than Ni-Cd battery: This statement is correct. Lithium-ion batteries have a higher energy density than Ni-Cd, allowing them to store more power per unit volume. This allows Li-ion batteries to be physically smaller. Additionally, Li-ion batteries have a slower self-discharge rate and do not require priming cycles making their maintenance requirements lower.
Lithium-ion battery is environmentally safer than Nickel-cadmium battery: This statement is correct. Li-ion batteries do not contain toxic cadmium like Ni-Cd batteries. This makes their disposal less hazardous to the environment. They are considered more eco-friendly.
