Direct UV-assisted, conformal protective coating of nanothickness poly(tris(2-(acryloyloxy)ethyl) phosphate) gel polymer electrolyte layers on high-voltage LiNi1/3Co1/3Mn1/3O2cathodes |
| 초록 |
As a facile and scalable approach to the surface modification of high-voltage cathode materials for lithium-ion batteries, direct UV-assisted conformal coating of poly(tris(2-(acryloyloxy)ethyl) phosphate) (PTAEP) gel polymer electrolyte on as-formed LiNi1/3Co1/3Mn1/3O2 (NCM) cathode is presented. The PTAEP coating layer with nanometer-thickness (∼20 nm) is successfully introduced on the NCM surface. The PTAEP-coated NCM cathode improves the high-voltage (4.6 V) cycling performance and Thermal Stability. This demonstrates that the PTAEP layer proposed herein, which is completely different from conventional inorganic material-based coating layers, acts as a new ion-conductive protective film that effectively suppresses unwanted interfacial side reactions between the high-voltage cathode materials and liquid electrolyte. |
