The synthesis of highly porous carbon (HPC) materials from poplar catkin by KOH
chemical activation and hydrothermal carbonization as a conductive additive to a lithium-sulfur
cathode is reported. Elemental sulfur was ...
Advanced design and fabrication of high performance sulfur cathodes with improved
conductivity and chemical adsorption towards lithium polysulfides (LiPS) are crucial for further
development of Li–S batteries. Hence, we ...
CuS is a metal sulfide anode material used in constructing lithium ion batteries (LIBs)
with great promise. However, its practical application is limited by rapid capacity decline,
poor cycling, and rate performance. In ...
Transition metal oxide Cu2O anode is still not meeting the current market demands due to the low theoretical capacity and poor cycle stability. We herein report the synthesis of a nanoporous GeO2/Cu/ Cu2O network by a ...
In recent years, the development of lithium-ion batteries (LIBs) with high energy density has become one of the important research directions to fulfill the needs of electric vehicles and smart grid technologies. Nowadays, ...
With the development of smart electronics, a wide range of techniques have been considered for efficient co-integration of micro devices and micro energy sources. Physical vapor deposition (PVD) by means of thermal ...
A gel polymer electrolyte was formed by trapping an optimized Na+/Zn2+ mixed-ion
aqueous electrolyte in a polyacrylonitrile nanofiber polymer matrix. This electrolyte was used in a
novel aqueous sodium-ion battery (ASIB) ...
Herein, we demonstrate the fabrication of a three-dimensional (3D) polypyrrole-coatedporous graphene (PPy/PG) composite through in-situ polymerization of pyrrole monomer on PG
surface. The PPy/PG displays a 3D hierarchical ...
A simple and effective method was developed to obtain the electrode for lithium/sulfur
(Li/S) batteries with high specific capacity and cycling durability via adopting an interconnected
sulfur/activated carbon/graphene ...
A three-dimensionally ordered macroporous ZnO (3DOM ZnO) framework was synthesized by a template method to serve as a sulfur host for lithium–sulfur batteries. The unique 3DOM structure along with an increased active surface ...
