Abstract The widespread deployment of lithium ion (Li+) batteries with increasing energy density entails a worsening safety concern. Among many contributing factors, the typical polymer separators are plagued with poor thermal stability,limited mechanical strength and lower Li+ transference number, and are prone to catastrophic failure when subjected to local thermalor mechanical stress (e.g., pierced by lithium dendrites). Herein, we report an all-inorganicnonwoven boron nitride nanotube membrane featuring exceptional chemical stability, thermal stability, fire resistance and mechanical flexibility. The resulting membranes show superior wettability to electrolyte to endow excellent Li+ transport properties with the lowest ionic resistance and the highest Li+ transference number (0.86) when compared with all commercial separators. They can thus function as highly robust separators for Li/Li symmetriccells with ultralow overpotential (8.5 mV) and exceptional reversibility for repeated lithium plating/stripping cycles for over 8000 hours, and for practical LiFePO4/Li cell with unusually high temperature stability. Our study defines a unique class of super electrolyte-philic ceramic separators with favorable mechanical strength, thermal stability and ion transfer properties for advanced lithium batteries.

An efficient approach for the preparation of good-quality boron nitride nanotubes (BNNTs) is developed. BNNTs with specific texture were prepared from ammonia borane (BH3NH3) by vapor-phase pyrolysis with the aid of a template in two independent temperature-controlled furnaces. Two kinds of BNNTs, 200–300 nm wide×60 μm long and 70–80 nm wide×40 μm long, were produced after removal of the templates. The as-produced BNNTs were heated at different temperatures in the range of 1300–1700°C inNH3. FT-IR and XPS results confirmed the formation of BN fromBH3NH3. Ordered arrays of BNNTs without cracks on the surface were seen using microstructural observations. The diameter and length of the BNNTs are controlled using templates with different pore sizes and thickness. The wall thickness of the nanotubes was increased by increasing the number of deposition cycles. The crystallinity of the BNNTs was improved by heating at a high temperature (1700°C) inNH3.
