英文摘要	High-voltage lithium-ion batteries have become a major research focus. As a major part of lithium batteries, the separator plays a critical role in the development of high-voltage lithium batteries. Herein, we demonstrated a sustainable and superior heat-resistant alginate nonwoven separator for high-voltage (5 V) lithium batteries. It was demonstrated that the resultant alginate nonwoven separator exhibited better mechanical property (37 MPa), superior thermal stability (up to 150 degrees C), and higher ionic conductivity (1.4 X 10(-3) S/cm) as compared to commercially available polyolefin (PP) separator. More impressively, the S V class LiNi0.5Mn15O4 (LNMO)/Li cell with this alginate nonwoven separator delivered much better cycling stability (maintaining 79.6% of its initial discharge capacity) than that (69.3%) of PP separator after 200 cycles at an elevated temperature of 55 degrees C. In addition, the LiFePO4/Li cell assembled with such alginate nonwoven separator could still charge and discharge normally even at an elevated temperature of 150 degrees C. The above-mentioned fascinating characteristics of alginate separator provide great probability for its application for high-voltage (5 V) lithium batteries at elevated temperatures.
