Supercritical CO2-Assisted SiOx/Carbon Multi-Layer Coating on Si Anode for Lithium-Ion Batteries
Rahmandhika Firdauzha Hary Hernandha,Purna Chandra Rath,Bharath Umesh,Jagabandhu Patra,Jagabandhu Patra,Chih Yang Huang,Wen-Wei Wu,Quanfeng Dong,Ju Li,Jeng Kuei Chang,Jeng Kuei Chang,Jeng Kuei Chang +11 more
TL;DR: In this paper, the supercritical CO2 (SCCO2) is applied to create a SiOx/carbon multi-layer coating on Si particles, which can buffer Si volume change during lithiation/delithiation and a conformal carbon film is deposited around the Si@SiOx core.
Journal ArticleDOI
High-Li$^{+}$-fraction ether-side-chain pyrrolidinium–asymmetric imide ionic liquid electrolyte for high-energy-density Si//Ni-rich layered oxide Li-ion batteries
Dave Rochlin,Bharath Umesh,Purna Chandra Rath,Jagabandhu Patra,Jagabandhu Patra,Rahmandhika Firdauzha Hary Hernandha,Subhasis Basu Majumder,Xinpei Gao,Dominic Bresser,Stefano Passerini,Hong Zheng Lai,Tseng Lung Chang,Jeng Kuei Chang,Jeng Kuei Chang,Jeng Kuei Chang +14 more
TL;DR: In this article, Si nanoparticles with interweaving carbon nanotubes are wrapped by graphitic sheets to achieve high conductivity and high dimensional stability of a composite anode (denoted as Si/CNT/G) for Li-ion batteries.
Journal ArticleDOI
Moderate-Concentration Fluorinated Electrolyte for High-Energy-Density Si//LiNi0.8Co0.1Mn0.1O2Batteries
Bharath Umesh,Purna Chandra Rath,Rahmandhika Firdauzha Hary Hernandha,Jeng Yu Lin,S. B. Majumder,Quanfeng Dong,Jeng Kuei Chang +6 more
TL;DR: In this paper, the authors investigate moderately concentrated electrolytes and find that the lithium bis(fluorosulfonyl)imide (LiFSI) concentration effects on the capacity, rate capability, and cycling stability of Si anodes in an ethylene carbonate/diethyl carbonate (DEC) mixed electrolyte are opposite to those in a fluoroethylene carbonate electrolyte.

N-Containing Carbon-Coated β-Si3 N4 Enhances Si Anodes for High-Performance Li-Ion Batteries.
Rahmandhika Firdauzha Hary Hernandha,B. Umesh,Purna Chandra Rath,Le Thi Thu Trang,Yu-Chun Chuang,Ju Li,Jeng Kuei Chang +6 more
TL;DR: In this paper , a carbon-coated β-Si3 N4 /Si composite anode was proposed for Li-ion battery applications, which showed specific capacities of 1068 and 480 mAh g-1 at 0.2 and 5 Ag-1 , respectively.
