Lithium Sulfur Battery Progress

March 18, 2010 | 21 Comments

Lithium based batteries are a hot research field with lithium air and lithium sulfur compounds at the top of research listings.  Stanford’s Yi Cui, builds the battery anode in the form of silicon nanowires, giving the silicon room to grow and shrink without damage.  That neatly solves silicon’s swelling when charged with positively charged lithium […]

A Battery So Good and Its Real

August 6, 2009 | 15 Comments

Japan’s National Institute of Advanced Industrial Science and Technology (AIST) researchers are developing a lithium-air cell with a new structure (a set of three different electrolytes) to avoid the degradation and performance problems of conventional lithium-air cells.  But the big news is in the discharge capacity. The newly developed lithium-air cell has shown a continuous […]
