  • Polar Polymer–solvent interaction derived favorable interphase for stable lithium metal batteries
    Energy & Environmental Science, 2019
    Co-Authors: Jiwoong Bae, Yumin Qian, Xingyi Zhou, John B. Goodenough
    Abstract:

    Lithium metal has long been regarded as one of the most promising anode materials for future rechargeable batteries. However, the severe reaction of Li with carbonate electrolytes and the rapid growth of Li-dendrites at high current densities hinder its practical application in Li-metal batteries. Here we report a Polar Polymer protective layer to suppress highly corrosive cyclic carbonates by tuning Polymer–solvent interactions. The CN groups of polyacrylonitrile (PAN) Polymer chains in the Polar Polymer network can effectively reduce high reactivity of the CO groups of carbonate solvents leading to a stable solid electrolyte interphase (SEI) layer with higher inorganic components. In situ optical and electron microscopes demonstrate that the Polar Polymer network effectively restrained the formation and growth of Li-dendrites, which helps to stabilize the plating/stripping behavior of Li in a symmetric Li|Li cell and a Li|LiNi1/3Co1/3Mn1/3O2 cell. This study provides a useful perspective of controlling electrolyte coordination to form a stable SEI layer in carbonate electrolytes for Li-metal batteries.

  • Enhancing the performance of lithium–sulfur batteries by anchoring Polar Polymers on the surface of sulfur host materials
    Journal of Materials Chemistry A, 2016
    Co-Authors: Manfang Chen, Xianyou Wang, Siyu Cai, Peng Song, Adrian C. Fisher
    Abstract:

    Lithium–sulfur (Li–S) batteries are attracting intense interest due to their high theoretical energy density and relatively low cost, but their practical applications are still hindered by quick capacity decay owing to the polysulfide shuttle effect. Based on the first-principles calculations, it has been found that the oxygen-containing functional groups (hydroxyl and ether group) of Triton X-100 are able to carry out effective trapping of lithium polysulfides by strong Li–O interactions, demonstrating a feasible strategy to alleviate the shuttle effect. Therefore, herein we present a facile and scalable synthetic route to suppress the polysulfide shuttle effect and further improve the overall performance of Li–S batteries through anchoring inherently Polar Polymer Triton X-100 on the surface of carbon materials. The results show that the MAC/S composite delivers a high discharge capacity of 1432 mA h g−1 in the first cycle, a capacity retention of 76% after 50 cycles at a rate of 0.2C with an excellent coulombic efficiency of 95% and a reversible specific capacity of above 889 mA h g−1 after 100 cycles at a rate of 0.5C with a low capacity decay of 0.3% per cycle.
