General hybrid asymmetric capacitor model: Validation with a commercial lithium ion capacitor
Journal of Power Sources, 2019 Modelling and numerical simulations play a vital role in the design and optimization of electrochemical energy storage devices. In this study, a general physics-based model is developed to describe Hybrid Asymmetric Capacitors (HACs). A one-dimensional cell is constructed with one faradaic electrode, a separator and a capacitive electrode. The model is

Radiation-induced separation and accumulation of electric charge in supercapacitors [PDF]
Nuclear Energy and Technology, 2018 In current sources with a radioactive isotope (CSRI), nuclear energy is directly converted into electricity due to the separation of electric charges during the decay of radioactive isotopes. It was previously shown that asymmetric supercapacitors can be

Asymmetric capacitors using lignin-based hierarchical porous carbons [PDF]
Journal of Power Sources, 2016 Hierarchical porous carbons (HPC) were fabricated from lignin by hard template method using Beta and Y zeolites as templates. Textural properties were dictated by the hard template, obtaining a bi-modal pore size distribution with similar micropore sizes but different mesopore sizes.

A Novel Dual-Mode Dual-Band Bandpass Filter Based on a Single Ring Resonator [PDF]
Journal of Electromagnetic Engineering and Science, 2020 In this paper, a dual-mode bandpass filter that operates in two different bands is proposed. A circular patch with a small circular hole is set as the basic resonator, and, as the circular hole moves, the linewidth of the ring resonator becomes non ...
