5) Lithium-ion batteries are the edifice of the wireless technology revolution. In this context discuss their significance and challenges facing these rechargeable Lithium Batteries.(250 words)
Why this question:
The article discusses in detail the coming of Li-ion batteries and in what way they have set off a technology revolution. The 2019 Nobel Prize for Chemistry was awarded to John B. Goodenough, M. Stanley Whittingham and Akira Yoshino for working towards the development of practical lithium-ion batteries, thus making it important from exam point of view.
Key demand of the question:
One has to explain in detail the technological revolution that Li-Ion batteries have brought in and the importance of the same with challenges.
Discuss – This is an all-encompassing directive – you have to debate on paper by going through the details of the issues concerned by examining each one of them. You have to give reasons for both for and against arguments.
Structure of the answer:
First explain the coming of Li-ion batteries.
Explain first why Li-ion batteries are important?
Discuss the genesis of the same.
Explain that For many years, nickel-cadmium had been the only suitable battery for portable equipment from wireless communications to mobile computing. Nickel-metal-hydride and lithium-ion emerged In the early 1990s, fighting nose-to-nose to gain customer’s acceptance. Today, lithium-ion is the fastest growing and most promising battery chemistry.
List down the advantages and limitations of the same.
Conclude with way forward.
