TOPIC: Science and Technology- developments and their applications and effects in everyday life
6) Explain how the Li-ion battery, which won for its developers the Chemistry Nobel, set off a technology revolution. ( 250 words)
Why this question:
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 it is important for us to learn from the examination perspective the utility of the concept.
Key demand of the question:
One must bring out in detail the merits associated with Li-ion batteries and in what way they have set a technological revolution.
Explain – Clarify the topic by giving a detailed account as to how and why it occurred, or what is the particular context. You must be defining key terms where ever appropriate, and substantiate with relevant associated facts.
Structure of the answer:
In brief define what lithium-ion batteries are.
Explain that these batteries are the edifice of the wireless technology revolution that made possible portable compact disc players, digital wrist watches, laptops and the mobile phones of today. It is also seen as important to a fossil free future of electric cars that governments envisage to address climate change.
Discuss the contributions of Goodenough and Yoshino.
Conclude with applications of such a revolutionary discovery.
