[clug] IBM claims to have made a new battery design that is environment friendly

[George at Clug]

Hi,


Has anyone read about this potential innovation?



I am hoping IBM manage to get this working, and working in the next 5
years. Thinks I use could be greatly improved and advanced if more
effective energy storage could be developed.

Overall, this battery has shown the capacity to outperform existing
lithium-ion batteries not only in the previously listed applications,
but can also be optimized for a range of specific benefits, including:



	* Lower cost: The active cathode materials tend to cost less
because they are free of cobalt, nickel, and other heavy
metals. These materials are typically very resource-intensive to
source, and also have raised concerns over their sustainability.
	* Faster charging: Less than five minutes required to reach an 80
percent state of charge (SOC), without compromising specific discharge
capacity.
	* High power density: More than 10,000 W/L. (exceeding the power
level that lithium-ion battery technology can achieve).
	* High energy density: More than 800 Wh/L, comparable to the
state-of-art lithium-ion battery.
	* Excellent energy efficiency: More than 90 percent (calculated from
the ratio of the energy to discharge the battery over the energy to
charge the battery).
	* Low flammability of electrolytes
