Carbon Nanosheet Frameworks Derived from Peat Moss as High Performance Sodium Ion Battery Anodes
Jia Ding,Huanlei Wang,Huanlei Wang,Zhi Li,Zhi Li,Alireza Kohandehghan,Alireza Kohandehghan,Kai Cui,Zhanwei Xu,Zhanwei Xu,Beniamin Zahiri,Beniamin Zahiri,Xuehai Tan,Xuehai Tan,Elmira Memarzadeh Lotfabad,Elmira Memarzadeh Lotfabad,Brian C. Olsen,Brian C. Olsen,David Mitlin,David Mitlin +19 more
TL;DR: It is demonstrated that peat moss, a wild plant that covers 3% of the earth's surface, serves as an ideal precursor to create sodium ion battery anodes with some of the most attractive electrochemical properties ever reported for carbonaceous materials.
Journal ArticleDOI
Colossal pseudocapacitance in a high functionality–high surface area carbon anode doubles the energy of an asymmetric supercapacitor
Zhi Li,Zhi Li,Zhanwei Xu,Zhanwei Xu,Huanlei Wang,Huanlei Wang,Jia Ding,Jia Ding,Beniamin Zahiri,Beniamin Zahiri,Chris M. B. Holt,Chris M. B. Holt,Xuehai Tan,Xuehai Tan,David Mitlin,David Mitlin +15 more
TL;DR: In this article, a template-free synthesis route was used to create macroscopically monolithic carbons that are both highly nitrogen rich (4.1-7.6 wt%) and highly microporous (SA up to 1405 m2 g−1, 88 vol% micropores).
Journal ArticleDOI
Anodes for Sodium Ion Batteries Based on Tin–Germanium–Antimony Alloys
Behdokht Farbod,Behdokht Farbod,Kai Cui,W. Peter Kalisvaart,W. Peter Kalisvaart,Martin Kupsta,Beniamin Zahiri,Beniamin Zahiri,Alireza Kohandehghan,Alireza Kohandehghan,Elmira Memarzadeh Lotfabad,Elmira Memarzadeh Lotfabad,Zhi Li,Zhi Li,Erik J. Luber,Erik J. Luber,David Mitlin,David Mitlin +17 more
TL;DR: HRTEM shows that Sn50Ge25Sb25 is a composite of 10-15 nm Sn and Sn-alloyed Ge nanocrystallites that are densely dispersed within an amorphous matrix, which leads to hypothesize that this new phenomenon originates from the Ge(Sn) that is able to sodiate beyond the 1:1 Na:Ge ratio reported for the pure element.
Journal ArticleDOI
Hybrid device employing three-dimensional arrays of MnO in carbon nanosheets bridges battery-supercapacitor divide.
Huanlei Wang,Zhanwei Xu,Zhanwei Xu,Zhi Li,Zhi Li,Kai Cui,Jia Ding,Jia Ding,Alireza Kohandehghan,Alireza Kohandehghan,Xuehai Tan,Xuehai Tan,Beniamin Zahiri,Beniamin Zahiri,Brian C. Olsen,Brian C. Olsen,Chris M. B. Holt,Chris M. B. Holt,David Mitlin,David Mitlin +19 more
TL;DR: This work created electrodes finely tuned for this purpose, consisting of a monolayer of MnO nanocrystallites mechanically anchored by pore-surface terminations of 3D arrays of graphene-like carbon nanosheets ("3D-MnO/CNS") that should offer a synthesis cost advantage over comparably performing designer nanocarbons, such as graphene or carbon nanotubes.
Journal ArticleDOI
Supercapacitive Properties of Hydrothermally Synthesized Co3O4 Nanostructures
Huatao Wang,Huatao Wang,Huatao Wang,Li Zhang,Li Zhang,Xuehai Tan,Xuehai Tan,Chris M. B. Holt,Chris M. B. Holt,Beniamin Zahiri,Beniamin Zahiri,Brian C. Olsen,Brian C. Olsen,David Mitlin,David Mitlin +14 more
TL;DR: In this paper, the authors demonstrate that minor differences in the synthesis temperature (50, 70°, or 90 °C) yield profound variations in the oxide microstructure, with lath-like, necklace-like and net-like morphologies of different scales resulting.
