Submission + - Ultra-High Capacity Lithium-Ion Batteries

Wdi writes: Currently, lithium-ion is the standard for high-density rechargeable batteries. Nevertheless, portable devices still run out of power far too quickly, or are too heavy because of battery bulk. Not much progress has been made in the last years to improve the capacity/weight ratio.

Until now. Chemical & Engineering News report about the development of breakthrough new LiIon battery cathode materials which have a sustained (repeated charge/discharge cycles) capacity/weight ratio nearly twice as high as LiCoO2, the standard cathode material.

Since the cathode is by far the heaviest part of a LiIon battery, this could lead to significantly lighter or more powerful batteries.

Nature always sides with the hidden flaw.
