Overview

Randomized trial demonstrates improved low-temperature performance in lithium-ion batteries, indicating potential for extreme applications.

Key Points

This research aims to enhance the low-temperature performance and cycling stability of lithium-ion batteries by optimizing electrolyte composition and interface characteristics.
Developed a systematic electrolyte containing methyl propionate, fluoroethylene carbonate, and bis(2,2,2-trifluoroethyl) ether.
Engineered a passivation layer (LiF and Li2CO3) on the electrode surface to reduce impedance.
Evaluated cycling performance using NCM523||Li and graphite||Li half-cells at varied temperatures.
The optimized electrolyte demonstrated a capacity retention of approximately 60% at -40 °C with a capacity of 90.5 mAh g−1 at 0.1 C.
The NCM523||graphite full cell showed satisfactory cycling performance at both room temperature and -20 °C.
High discharge capacities were achieved, measuring 104.5 and 245.2 mAh g−1 from NCM523/Li and graphite/Li half cells, respectively, under low-temperature conditions.
