CNC in lithium batteries
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.
