Fabrication of high-performance dual carbon Li-ion hybrid capacitor: mass balancing approach to improve the energy-power density and cycle life
(Nature, 2020-07-02)Most lithium-ion capacitor (LIC) devices include graphite or non-porous hard carbon as negative electrode often failing when demanding high energy at high power densities. Herein, we introduce a new LIC formed by the ... -
Fabrication Quality Assessment Based on the Coupling of a Dual-Core Microstructured Polymer Optical Fiber
Berganza Valmala, Amaia; Arrospide Zabala, Eneko; Amorebieta Herrero, Josu ; ; Durana Apaolaza, Gaizka (MDPI, 2021-11-09)
In this paper we report on the theoretical analysis and fabrication of a dual-core microstructured polymer optical fiber (mPOF) and demonstrate how the coupling characteristics of a dual-core mPOF may be a key factor to ... -
