Journal ArticleDOI
Promise and reality of post-lithium-ion batteries with high energy densities
Jang Wook Choi,Doron Aurbach +1 more
TL;DR: A review of post-lithium-ion batteries is presented in this paper with a focus on their operating principles, advantages and the challenges that they face, and the volumetric energy density of each battery is examined using a commercial pouch-cell configuration.
Journal ArticleDOI
Stable cycling of double-walled silicon nanotube battery anodes through solid-electrolyte interphase control
Hui Wu,Gerentt Chan,Jang Wook Choi,Jang Wook Choi,Ill Ryu,Yan Yao,Matthew T. McDowell,Seok Woo Lee,Ariel Jackson,Yuan Yang,Liangbing Hu,Yi Cui,Yi Cui +12 more
TL;DR: It is shown that anodes consisting of an active silicon nanotube surrounded by an ion-permeable silicon oxide shell can cycle over 6,000 times in half cells while retaining more than 85% of their initial capacity.
Journal ArticleDOI
Nitrogen-doped graphene for high-performance ultracapacitors and the importance of nitrogen-doped sites at basal planes.
Hyung Mo Jeong,Jung Woo Lee,Weon Ho Shin,Yoon Jeong Choi,Hyun-Joon Shin,Jeung Ku Kang,Jang Wook Choi +6 more
TL;DR: Using nitrogen-doped graphene produced by a simple plasma process, ultracapacitors are developed whose capacitances are about 4 times larger than those of pristine graphene based counterparts without sacrificing other essential and useful properties for ultracAPacitor operations including excellent cycle life, high power capability, and compatibility with flexible substrates.
Journal ArticleDOI
Stretchable, Porous, and Conductive Energy Textiles
Liangbing Hu,Mauro Pasta,Fabio La Mantia,Lifeng Cui,Sangmoo Jeong,Heather Dawn Deshazer,Jang Wook Choi,Seung Min Han,Yi Cui +8 more
TL;DR: Wearable power devices using everyday textiles as the platform, with an extremely simple "dipping and drying" process using single-walled carbon nanotube (SWNT) ink, are described, which show outstanding flexibility and stretchability and demonstrate strong adhesion between the SWNTs and the textiles of interest.
Journal ArticleDOI
3D Macroporous Graphene Frameworks for Supercapacitors with High Energy and Power Densities
TL;DR: High-performance supercapacitors are demonstrated by building a three-dimensional (3D) macroporous structure that consists of chemically modified graphene (CMG) that endows MnO(2)/e-CMG composite electrodes with excellent electrochemical properties.
