چکیده

All-solid-state batteries (ASSBs) using organic ionic plastic crystals (OIPCs) are promising candidates to overcome the inherent safety issues of lithium-ion (LIBs). Although OIPCs have excellent process applicability in roll-to-roll electrode fabrication process, their application as solid electrolytes incorporated composite electrodes has yet be demonstrated detail. Herein, we denote positive effect N-ethyl-N-methylpyrrolidinium bis(fluorosulfonyl)imide ([C2mpyr][FSI]) within a graphite anode on charge rate capability and cycle life. The highest capacity ratio (the at 2C vs. that measured 0.1C) was for with an OIPC 50 wt % (89.5 %, 295.7 mAh/g charge), almost same liquid electrolyte (85.7 295.9 charge). More favorable conduction pathways were resolved higher ratio, whereas excessive amount reduced long-term cyclability. most stable discharge retention obtained 30 (257.4 100th discharge), which showed no signs fading 100 cycles. lithiation/delithiation solid-state graphite-[C2mpyr][FSI] evaluated reversible. In addition, enhanced electrolyte/electrode electrode/current collector contacts. This work highlights multiple advantageous functions anode, will broaden our horizons use composites ASSBs.

Charge–discharge stability of graphite anodes for lithium-ion batteries

A graphite powder disk sandwiched between two nickel screens was used as a lithium-insertion working electrode. Electrochemical impedance spectroscopy (EIS), galvanostatic intermittent titration (GIT) using pulsed microcurrent, and in-situ intrinsic resistance measurements were used for the evaluation of kinetics and intrinsic (i.e. physical) resistance changes during charge–discharge cycling f...

Single-phased Organic Plastic Crystal Electrolytes

In this work we report on the conductivity, thermal and electrochemical behaviour of one member of a new family of organic plastic crystal electrolytes, the N,N’-trimethylenepyrazolium trifluoromethanesulfonimide, Pyr5. The salt shows a single plastic crystalline phase with ionic conductivities reaching up to 10-3 S.cm-1 in the solid state at low doping levels with a lithium imide salt. The Tem...

Relaxation dynamics and ionic conductivity in a fragile plastic crystal.

We report a thorough characterization of the dielectric relaxation behavior and the ionic conductivity in the plastic-crystalline mixture of 60% succinonitrile and 40% glutaronitrile. The plastic phase can be easily supercooled and the relaxational behavior is investigated by broadband dielectric spectroscopy in the liquid, plastic crystalline, and glassy crystal phases. The α-relaxation found ...
