Correct option is A
• Statement I is incorrect because lithium-ion batteries are secondary (rechargeable) cells. Non-rechargeable electronics generally use primary lithium cells, alkaline cells, or coin cells.
• Statement II is correct: lithium-ion technology provides high specific energy, low self-discharge, and lightweight power sources, making them the dominant choice for portable electronics and electric mobility devices.
• Statement III is correct: these batteries may undergo thermal runaway due to internal short circuit, overcharging, or external damage.
– Thermal runaway can rapidly increase temperature and pressure, leading to fire or explosion.
• Therefore, correct statements are II and III only.
