Strongly performing lithium batteries that also promise the potential of recyclability or biodegradability are beginning to become possible with the application of CNC in this field. One recent offering is a paper from Christian Hänsel et al from ETH, Switzerland. They have constructed a lithiated mesoporous membrane. This CNC membrane, infused with organic solvent (ethylene carbonate/ diethyllcarbonate) shows a good Li-ion conductivity of 0.2 ×10?4 S cm?1 at room temperature, a near unity Li+ transference number (?Li+ = 0.93), and a wide operational window (?4.5 V) against Li. These properties of the CNC ionomer electrolyte enable smooth Li metal deposition and stable cycling of Li-LiFePO4 cells.
