1. What are the main advantages of lithium-ion batteries?

Lithium-ion batteries offer high energy density (150–250 Wh/kg), lightweight design, and fast charging. They are the go-to power source for smartphones, laptops, EVs, and industrial applications.

2. Are lithium-ion batteries safe to use?

Yes — lithium-ion batteries are safe when properly designed and manufactured to recognized standards and used with an appropriate BMS that handles cell balancing, over-charge/over-discharge, short-circuit and temperature protection. Use chargers matched to the battery chemistry, ensure good thermal and mechanical design, follow manufacturer storage/temperature/SOC guidelines, and choose certified products (e.g., IEC 62133, UL, UN38.3) from reputable manufacturers to minimize risk.

3. How do lithium-ion batteries compare to Ni-MH batteries?

Lithium-ion batteries are 30–50% lighter, last up to 2x longer, and charge faster, making them a better option for EVs and power tools. Ni-MH batteries are cheaper but more common in low-cost consumer electronics.

4. Where are lithium-ion batteries commonly used?

They power consumer electronics, drones, solar lamps, and medical, offering higher performance and reliability compared to other battery types.
