Journal ArticleDOI
Insertion-Type Electrodes for Nonaqueous Li-Ion Capacitors
TL;DR: This paper aims to demonstrate the efforts towards in-situ applicability of EMMARM, as to provide real-time information about concrete mechanical properties such as E-modulus and compressive strength.
Journal ArticleDOI
Flexible energy storage devices based on graphene paper
Hyeokjo Gwon,Hyun-Suk Kim,Kye Ung Lee,Dong-Hwa Seo,Yun Chang Park,Yun-Sung Lee,Byung Tae Ahn,Kisuk Kang,Kisuk Kang +8 more
TL;DR: In this article, the use of a flexible electrode based on free-standing graphene paper, to be applied in lithium rechargeable batteries was proposed. And the results showed that the graphene-based flexible electrode exhibits significantly improved performances in electrochemical properties, such as in energy density and power density.
Journal ArticleDOI

Haegyeom Kim,Min-Young Cho,Mok-Hwa Kim,Kyu-Young Park,Hyeokjo Gwon,Yun-Sung Lee,Kwang Chul Roh,Kisuk Kang +7 more
TL;DR: In this article, a hybrid supercapacitor with high energy and power densities is presented, which comprises a composite anode of anatase TiO2 and reduced graphene oxide and an activated carbon cathode in a non-aqueous electrolyte.
Journal ArticleDOI
Research Progress on Negative Electrodes for Practical Li‐Ion Batteries: Beyond Carbonaceous Anodes
TL;DR: In this paper, a review of negative electrodes for construction of high-performance Li-ion batteries with conventional cathodes such as LiCoO2, LiFePO4, and LiMn2O4 are described.
Journal ArticleDOI
LiMnPO4 - A next generation cathode material for lithium-ion batteries
TL;DR: LiMnPO4 cathodes have been investigated in both native and substituted forms along with carbon coating synthesized by various synthetic techniques as mentioned in this paper, and the results are compared with previous literature values.
