GS-III: Nobel Prize in Chemistry: for Lithium ion battery.
This year’s Nobel Prize in Chemistry recognizes the rechargeable lithium-ion batteries that power most of the portable devices that we use, such as mobile phones and more recently the e-vehicles. The prize has been given jointly to Stanley Whittingham, John B Goodenough and Akira Yoshino.
Advantages of Li-Ion Batteries:
Low maintenance: One major lithium ion battery advantage is that they do not require and maintenance to ensure their performance. Ni-Cad cells required a periodic discharge to ensure that they did not exhibit the memory effect. As this does not affect lithium ion cells, this process or other similar maintenance procedures are not required.
High energy density: The high energy density is one of the chief advantages of lithium ion battery technology. With electronic equipment such as mobile phones needing to operate longer between charges while still consuming more power, there is always a need to batteries with a much higher energy density. In addition to this, there are many power applications from power tools to electric vehicles. The much higher power density offered by lithium ion batteries is a distinct advantage. Electric vehicles also need a battery technology that has a high energy density.
How it is different from conventional batteries?
