Consider the following statements: Lithium-Ion batteries are not r...
Statement 1 is incorrect: Lithium-ion batteries convert chemical energy into electrical energy using an electrochemical reaction (using cathode, anode and electrolyte.) These reactions are reversible and so a lithium battery once depleted can be recharged again. Therefore, it is used in portable electronics like smartphones, laptops, etc.
Statement 2 is correct: They tend to overheat and can be damaged at high voltages. In some cases, this can lead to combustion. This can cause transportation restrictions on large quantities of Li-ion batteries. It is one of the few limitations of Lithium-ion batteries.
Knowledge Base:
A lithium-ion battery is a type of rechargeable battery.
The 2019 Nobel Prize in Chemistry was awarded to John D. Goodenough, M. Stanley Whittingham and Akira Yoshino for their roles in the development of lithium-ion batteries.
Advantages:
- It is light weight and has high energy density.
- Li-ion battery cells can deliver up to 3.6 Volts, 3 times higher than technologies such as Nickel Cadmium (Ni-Cd) batteries.
- Rechargeable lithium-ion batteries have 5000 cycles or more compared to just 400- 500 cycles in lead acid batteries.
- Li-ion batteries are also comparatively low maintenance, and do not require scheduled cycling to maintain their battery life.
- Li-ion batteries have no memory effect, a detrimental process where repeated partial discharge/charge cycles can cause a battery to ‘remember’ a lower capacity.
- Li-ion batteries also have a low self-discharge rate of around 1.5-2% per month.
- They do not contain toxic cadmium, which makes them easier to dispose of than Ni-Cd batteries.
Limitations of Li- ion batteries:
- Li-ion batteries require safety mechanisms to limit voltage and internal pressures, which can increase weight and limit performance in some cases.
- Another factor limiting their widespread adoption is their cost, which is around 40% higher than Ni-Cd

Lithium-Ion batteries are not rechargeable and have to be discarded after being exhausted:
This statement is incorrect. Lithium-Ion batteries are indeed rechargeable. They are widely used in various electronic devices such as smartphones, laptops, electric vehicles, and more. The primary advantage of Lithium-Ion batteries is their ability to be recharged multiple times without losing their capacity significantly. They have a high energy density, which allows them to store a large amount of energy in a compact size. When the battery is exhausted, it can be recharged using a charger specifically designed for Lithium-Ion batteries. This makes them a more sustainable and environmentally friendly option compared to non-rechargeable batteries.
High voltages can sometimes cause the Lithium-ion batteries to burst and catch fire:
This statement is correct. Lithium-Ion batteries are known to be sensitive to high voltages, especially when they are overcharged or exposed to extreme conditions. Overcharging a Lithium-Ion battery can cause the formation of lithium metal on the anode, leading to internal short circuits and thermal runaway. This can result in the battery overheating, swelling, bursting, or even catching fire. To prevent such incidents, Lithium-Ion batteries are equipped with safety features such as protection circuits that monitor the voltage and temperature to ensure safe operation. However, under certain circumstances, such as manufacturing defects or misuse, Lithium-Ion batteries can still be prone to thermal runaway and fire hazards.
Overall, Lithium-Ion batteries are rechargeable and offer several advantages over non-rechargeable batteries. However, they do require proper handling and precautions to avoid potential risks associated with high voltages and thermal runaway. It is essential to follow the manufacturer's guidelines and use appropriate charging equipment to ensure the safe and efficient use of Lithium-Ion batteries.
