Well-percolated Na2C4O4-based electrodes have been realized to determine the nature of oxidation products squarate anion (C4O42−), and then Na2C4O4 has applied as a sacrificial material presodiate anodic host sodium-ion system. During electrochemical C4O42−, potential plateau with an irreversible capacity close theoretical one (339 mAh g−1) was observed ca. 3.6 V vs. Na/Na+. The mass variation carbon-Na2C4O4 electrodes, together spectrometry analysis gas phase, suggested that product C4O42-...
Herein, we disclose a strategy to optimize the performance of metal-ion capacitors (MICs) incorporating an activated carbon (AC)-positive electrode and battery-type anode with large specific capacity. The is illustrated on example sodium-ion capacitor (NIC) in which anodic material based Sn4P3 alloy combined hydrothermal hard from glucose (HCG) used buffer volumetric changes during sodium insertion/deinsertion Sn4P3. To simultaneously enhance energy life span NICs, capacity ratio, Q-/Q+,...
Nowadays, improving the energy output of electrochemical capacitors (ECs) is still a challenge for researchers. In this context, lithium-ion (LICs) which exhibit higher density than EDLCs, at comparable power, are considered to be very promising storage devices. However, necessary pre-lithiation negative graphite electrode constitutes drawback these systems. first concept LIC, metallic lithium was used as auxiliary [1]. Since additional complicates cell construction and may cause safety...
