High performance screen printable lithium-ion battery cathode ink based on C-LiFePO4

The developed cathodes show an initial discharge capacity of 48.2 mAh g−1 at 5C and a discharge value of 39.8 mAh g−1 after 50 cycles. The capacity retention of 83% represents 23% of the theoretical value (charge and/or discharge process in twenty minutes), demonstrating the good performance of the battery. Thus, the developed C-LiFePO4 based inks allow to fabricate screen-printed cathodes suitable for printed lithium-ion batteries.
