The new structure relies on the active metal oxide material to provide support for the weaker current collector during the manufacturing process, thereby disposing the need to use any inactive material as a support structure. This new method and structure carries a higher volumetric energy density because there is no room wasted on a scaffold.

Read More [3] Dr. Kenis from the University of Illinois at Urbana-Champaign has developed a non-aqueous lithium-air flow battery configuration that allows for efficient removal and storage of discharge products. This technology has applications in energy storage, particularly in the electric vehicle market due to its improved current density and discharge capacity. In comparison to traditional Li-ion batteries, the Li-air battery is lighter and has a higher practical energy density. This technology helps to overcome the buildup of discharge products.

SolvSEM: New Solid Electrolytes for Lithium Batteries with Improved Performance and Processability [5] Prof. Andrew Gewirth from the University of Illinois has developed a new technology which improves the safety, stability and processability of solid state batteries.... Read More [5] Prof. Andrew Gewirth from the University of Illinois has developed a new technology which improves the safety, stability and processability of solid state batteries. Commercial liquid electrolytes (LEs) pose a fire and explosion hazard in lithium metal batteries due to the possibility of thermal runaway reactions. Solid electrolytes (SEs) have become a practical option for lithium ion and lithium metal batteries due to their improved safety over commercially available ionic liquids. However, current SE technologies suffer from poor stability and are difficult to process. Prof. Gewirth’s invention enhances the ease of processability of electrolytes for lithium metal batteries, increases the mechanical stability of the electrolyte, reduces the overall cost of the cell, and reduces the overall cell resistance. SolvSEM has a lower overall cell resistance than its bare pellet counterpart Stable over 100 cycles \| Current density x10 higher than pellet counterpart
