South Korean researchers at the Center
for Self-assembly and Complexity, institute
for Basic Science, have created a new lithion
ion battery from a porous solid which great-
ly improves its performance.
The new battery is built from pumpkin-
shaped molecules called cucurbit[6]uril
(CB[6]) which are organized in a honey-
comb-like structure.
what makes this new technique exciting
is that it is a new method of preparing a
solid lithium electrolyte which starts as a liq-
uid, but no post-synthetic modification or
chemical treatment is needed.
New Lithium Ion Battery is Safer,
Tougher, and More Powerful
