Journal ArticleDOI

Interconnected Carbon Nanosheets Derived from Hemp for Ultrafast Supercapacitors with High Energy

TL;DR: These exquisite carbons were able to be achieved by simple hydrothermal carbonization combined with activation by taking advantage of the complex multilayered structure of a hemp bast fiber precursor, providing among the best power-energy characteristics ever reported for an electrochemical capacitor.
Journal ArticleDOI

Carbon Nanosheet Frameworks Derived from Peat Moss as High Performance Sodium Ion Battery Anodes

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

High-density sodium and lithium ion battery anodes from banana peels

TL;DR: A combination of XRD and XPS demonstrates highly reversible Na intercalation rather than metal underpotential deposition, and the same analysis proves the presence of metallic Li in the pores, withintercalation being much less pronounced.
Journal ArticleDOI

Peanut shell hybrid sodium ion capacitor with extreme energy–power rivals lithium ion capacitors

TL;DR: In this paper, a hybrid sodium ion capacitor with the active materials in both the anode and the cathode being derived entirely from a single precursor: peanut shells, which are a green and highly economical waste globally generated at over 6 million tons per year.
Journal ArticleDOI

Anodes for Sodium Ion Batteries Based on Tin–Germanium–Antimony Alloys

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.
