A PM’s Dare ?

At recently concluded 107^th Indian Science Congress, Shri Narendra Modi challenged the scientists to develop new battery types , saying :

“ We need to pay attention to grid management as we expand our renewable energy

supply.

These require developing new battery types which are ,

Ø based on environmentally benign materials,

Ø not monopolistic,

Ø affordable on 100s of Giga-Watt scale,

Ø suitable for tropical climates ”

=====================================================

Scientists from Monash University ( Australia ) , seem to have come up with just such a battery !

Here is that report :

New Lithium Battery Can Power Your Phone For 5 Days

Extract :

Ø Now, researchers have developed a lithium-sulfur battery that could power a smartphone for five days straight or can also enable an electric vehicle to drive for over 1000km.

Ø The lithium-sulfur battery developed by researchers from Monash University has an ultra-high capacity with better performance and less environmental impact than the commercially-used lithium-ion batteries

Ø The new battery design has

# Higher capacity,

# Better performance,

# Lower manufacturing costs,

# Abundant material supply,

# Fluent manufacturing process, and

# Reduced environmental footprint

Ø Outperforming the batteries in the market by over four times, it is the world's most efficient lithium-sulphur (Li-S) battery design making it promising for large-scale real-world applications.

Ø Professor Majumder from Monash University explained,

“Successful fabrication and implementation of Li-S batteries in cars and grids will capture a more significant part of the estimated $213 billion value chain of Australian lithium, and will revolutionise the Australian vehicle market and provide all Australians with a cleaner and more reliable energy market.”
