Inhibiting Sulfur Shuttle Behaviors in High-Energy Lithium-Sulfur Batteries


Practical Lithium-Sulfur Battery Technology


The on-going problem of atmospheric pollution due to the burning of fossil fuels has not yet been effectively solved, though some progress has been made.  Currently, the most promising of the alternative energy sources are wind and solar.  However, as is well known, both of these energy sources are intermittent and will require the development of highly efficient energy storage devices before wind and solar energy can replace fossil fuels as a the primary energy supply for the planet.  Improved battery technology is therefore crucial for the future of clean, economical and reliable energy production.


There have been significant advances in battery technology in the last thirty years, however, battery technology still has a long way to go before batteries will be a completely satisfactory storage medium for energy derived from solar and wind power.  The primary problem with the current electrical battery technology is that it can’t store enough energy in a small enough space.  One of the most promising new battery technologies is the Lithium-Sulfur Battery, which has a capacity of almost ten times that of Lithium Ion batteries now in use. 


However, the Lithium-Sulfur battery has a significant drawback, a technical problem known as the sulfur shuttle phenomenon.  A new invention is aimed at eliminating the problem and promises to be a breakthrough that will make the Lithium-Sulfur battery truly economical.


The new invention is the subject of a provisional patent application and is now available for license.
