Abstract

Lithium-ion batteries (LIBs) are widely used and considered as an ideal power supply for different applications. However, severe power/energy loss and lithium dendrite growth at low temperatures are still major problems for the graphite-based LIBs. Here we develop a highly stable nano ω-Li3V2O5 anode (named n-LVO-H) with a suitable lithium embedding potential via a chemical method. Benefiting from a short Li+ transport path, the product n-LVO-H anode accelerates the diffusion of Li+ in the particles. In addition, a robust solid-electrolyte interface layer built on the n-LVO-H particles using 1,3-dioxolane (DOL) based electrolyte with low desolvation energy facilitates Li+ transport at the interface. Such an unconventional combination of nano-size anode material with DOL electrolyte renders the n-LVO-H cell high C-rate capacity (207.1 mAh g−1 at 10C), while enjoying cycling stability (92.93 % retention at 10C after 1000 cycles) and low-temperature tolerance (248.1 mAh g−1 at -20 °C and 0.2C) concurrently.
