Lithium-Sulfur (Li-S) batteries promise much higher energy storage capacity at lower cost compared to conventional lithium-ion technologies because sulfur is inexpensive and plentiful. A key challenge for Li-S batteries has been the controlling polysulfides formation during battery cycling, which can result in a rapid decline in performance. JCSER researchers have developed several new technologies aimed at improving the performance of Li-S batteries, including issued US patents relating to new electrode and binder materials.
