  • design of hierarchical nico nico layered double hydroxide core shell structured nanotube array for high performance flexible all Solid State Battery type supercapacitors
    Advanced Functional Materials, 2017
    Co-Authors: Nianqing Fu, Guoge Zhang, Limin Zhou, Wei Lu, Ming Xu, Haitao Huang
    Abstract:

    A novel hierarchical nanotube array (NTA) with a massive layered top and discretely separated nanotubes in a core–shell structure, that is, nickel–cobalt metallic core and nickel–cobalt layered double hydroxide shell (NiCo@NiCo LDH), is grown on carbon fiber cloth (CFC) by template-assisted electrodeposition for high-performance supercapacitor application. The synthesized NiCo@NiCo LDH NTAs/CFC shows high capacitance of 2200 F g−1 at a current density of 5 A g−1, while 98.8% of its initial capacitance is retained after 5000 cycles. When the current density is increased from 1 to 20 A g−1, the capacitance loss is less than 20%, demonstrating excellent rate capability. A highly flexible all-Solid-State Battery-type supercapacitor is successfully fabricated with NiCo LDH NTAs/CFC as the positive electrode and electrospun carbon fibers/CFC as the negative electrode, showing a maximum specific capacitance of 319 F g−1, a high energy density of 100 W h kg−1 at 1.5 kW kg−1, and good cycling stability (98.6% after 3000 cycles). These fascinating electrochemical properties are resulted from the novel structure of electrode materials and synergistic contributions from the two electrodes, showing great potential for energy storage applications.

    Co-Authors: W.a. Gazotti, G. Casalbore-miceli, N. Camaioni, Marco-a. De Paoli, A.m. Fichera
    Abstract:

    A Solid-State Battery was constructed by interfacing a pressed pellet of poly(o-methoxyaniline), in the emeraldine form with p-toluene sulfonic acid as doping agent, to a magnesium electrode covered with a film of magnesium perchlorate; the contact on the poly(o-methoxyaniline) was done by means of a gold electrode. The so-obtained cell, Mg I magnesium perchlorate I poly(o-methoxyaniline) I gold, was able to supply energy with a power depending on discharge current and on environmental humidity. Values of power up to 2.5 mW cm(-2) at discharge currents of about 2 mA cm(-2) were reached. (C) 1997 Elsevier Science S.A.

  • li metal deposition and stripping in a Solid State Battery via coble creep
    Nature, 2020
    Co-Authors: Yutao Li, Yuming Chen, Ziqiang Wang, Xiaoyan Li, Chao Wang, Daiwei Yu, Fei Yang, Akihiro Kushima, Guoge Zhang
    Abstract:

    Solid-State lithium metal batteries require accommodation of electrochemically generated mechanical stress inside the lithium: this stress can be1,2 up to 1 gigapascal for an overpotential of 135 millivolts. Maintaining the mechanical and electrochemical stability of the Solid structure despite physical contact with moving corrosive lithium metal is a demanding requirement. Using in situ transmission electron microscopy, we investigated the deposition and stripping of metallic lithium or sodium held within a large number of parallel hollow tubules made of a mixed ionic-electronic conductor (MIEC). Here we show that these alkali metals—as single crystals—can grow out of and retract inside the tubules via mainly diffusional Coble creep along the MIEC/metal phase boundary. Unlike Solid electrolytes, many MIECs are electrochemically stable in contact with lithium (that is, there is a direct tie-line to metallic lithium on the equilibrium phase diagram), so this Coble creep mechanism can effectively relieve stress, maintain electronic and ionic contacts, eliminate Solid-electrolyte interphase debris, and allow the reversible deposition/stripping of lithium across a distance of 10 micrometres for 100 cycles. A centimetre-wide full cell—consisting of approximately 1010 MIEC cylinders/Solid electrolyte/LiFePO4—shows a high capacity of about 164 milliampere hours per gram of LiFePO4, and almost no degradation for over 50 cycles, starting with a 1× excess of Li. Modelling shows that the design is insensitive to MIEC material choice with channels about 100 nanometres wide and 10–100 micrometres deep. The behaviour of lithium metal within the MIEC channels suggests that the chemical and mechanical stability issues with the metal–electrolyte interface in Solid-State lithium metal batteries can be overcome using this architecture. By containing lithium metal within oriented tubes of a mixed ionic-electronic conductor, a 3D anode for lithium metal batteries is produced that overcomes  chemomechanical stability issues at the electrolyte interface.
