Q. Consider the following statements with respect to the differences between the solid-state battery and lithium-ion battery:
1.The electrolyte is solid in the solid- state battery whereas in lithium-ion batteries electrolyte is liquid.
2.A solid-state battery has higher energy density than a Lithium-ion.
3.Solid-state batteries can last longer than traditional lithium-ion batteries due to their improved stability.
Which of the statements given above are correct?
Answer: D
Notes:
Explanation –
Statements 1, 2 and 3 are correct. Solid-state batteries have almost the same mechanism as lithium-ion batteries for extracting electricity from the batteries. However, the key difference is solid-state batteries use a solid electrolyte, while lithium-ion batteries use a liquid electrolyte. Solid-state batteries have the potential for significantly higher energy density compared to lithium-ion batteries. This means they can store more energy per unit weight or volume, leading to longer range for electric vehicles or increased capacity for portable devices. Solid-state batteries are expected to have a longer lifespan compared to traditional lithium-ion batteries.
