    Nano Energy, 2019
    Co-Authors: Xue Wang, Haowei Zhai, Boyu Qie, Qian Cheng, James Borovilas, Changmin Shi, Tianwei Jin, Xiangbiao Liao, Martin Dontigny
    Abstract:

    Abstract Composite solid Electrolytes are attractive as they combine the high ionic conductivity of ceramic nanoparticles and the excellent mechanical properties of polymer Electrolytes. Vertically aligned ceramic nanoparticles in the polymer matrix represent an ideal structure for maximizing ionic conductivity of composite Electrolytes. The ice-templating method was used to build rechargeable solid-state lithium metal batteries with a vertically aligned ceramic/polymer composite electrolyte composed of high ionic conductivity Li1.5Al0.5Ge1.5(PO4)3 (LAGP) and polyethylene oxide (PEO) polymer. The vertical LAGP walls provide continuous channels for fast ionic transport, while the PEO matrix renders the composite electrolyte flexible. This solid-state composite electrolyte has a conductivity of 1.67 × 10−4 S cm−1 at room temperature and 1.11 × 10−3 S cm−1 at 60 °C. LiFePO4 (LFP)/vertically aligned LAGP- PEO/Li full cells were also developed with a high capacity retention of 93.3% after 300 cycles. This study demonstrates the successful application of vertically aligned ceramic/polymer composite Electrolytes for solid-state batteries with high performance.

  • improved Electrolytes for li ion batteries mixtures of ionic liquid and organic electrolyte with enhanced safety and electrochemical performance
    Journal of Power Sources, 2010

    Abstract:

    Abstract Physical and electrochemical characteristics of Li-ion battery systems based on LiFePO4 cathodes and graphite anodes with mixture Electrolytes were investigated. The mixed Electrolytes are based on an ionic liquid (IL), and organic solvents used in commercial batteries. We investigated a range of compositions to determine an optimum conductivity and non-flammability of the mixed electrolyte. This led us to examine mixtures of ILs with the organic electrolyte usually employed in commercial Li-ion batteries, i.e., ethylene carbonate (EC) and diethylene carbonate (DEC). The IL electrolyte consisted of (trifluoromethyl sulfonylimide) (TFSI) as anion and 1-ethyl-3-methyleimidazolium (EMI) as the cation. The physical and electrochemical properties of some of these mixtures showed an improvement characteristics compared to the constituents alone. The safety was improved with electrolyte mixtures; when IL content in the mixture is ≥40%, no flammability is observed. A stable SEI layer was obtained on the MCMB graphite anode in these mixed Electrolytes, which is not obtained with IL containing the TFSI-anion. The high-rate capability of LiFePO4 is similar in the organic electrolyte and the mixture with a composition of 1:1. The interface resistance of the LiFePO4 cathode is stabilized when the IL is added to the electrolyte. A reversible capacity of 155 mAh g−1 at C/12 is obtained with cells having at least some organic electrolyte compared to only 124 mAh g−1 with pure IL. With increasing discharge rate, the capacity is maintained close to that in the organic solvent up to 2 C rate. At higher rates, the results with mixture Electrolytes start to deviate from the pure organic electrolyte cell. The evaluation of the Li-ion cells; LiFePO4//Li4Ti5O12 with organic and, 40% mixture Electrolytes showed good 1st CE at 98.7 and 93.0%, respectively. The power performance of both cell configurations is comparable up to 2 C rate. This study indicates that safety and electrochemical performance of the Li-ion battery can be improved by using mixed IL and organic solvents.
