Large energy density batteries and methods of manufacture
MetadataShow full item record
Embodiments of the claimed invention are directed to a device, comprising: an anode that includes a lithiated silicon-based or lithiated carbon-based material or pure lithium metal or metal oxides and a sandwich-type sulfur-based cathode, wherein the anode and the cathode are designed to have porous structures. An additional embodiment of the invention is directed to a scalable method of manufacturing sandwich-type Li--S batteries at a significantly reduced cost compared to traditional methods. An additional embodiment is directed to the use of exfolidated CNT sponges for enlarging the percentage of sulfur in the cathode to have large energy density.
