Abstract

Potassium (K) with higher abundance than lithium has been explored as an anode material for K metal batteries (KMBs) for possible application in large-scale energy storage. However, the unstable solid electrolyte interface (SEI) at the K anode due to uncontrolled growth of K dendrites is a challenge in KMB development. In this paper, a multifunctional interface containing Sb2O3 and reduced graphene oxide (rGO) on Cu foam to form a current collector (Cu@Sb2O3@rGO) is developed for a KMB anode through structural regulation, where the Cu form with a large surface area can reduce the volume change during charge and discharge processes, Sb2O3 can provide potassiophilicity toward uniform K plating and stripping to give a dendrite-free K anode, and rGO can provide abundant defects for increasing the ion transport and reaction kinetics. Such a Cu@Sb2O3@rGO current collector exhibits a remarkable reversibility of K plating/stripping for up to 600 cycles at 0.5 mA cm−2/2 mA h cm−2, and the formed Cu@Sb2O3@rGO@K anode demonstrates an extended cycle lifespan of 1300 hours under 0.2 mA cm−2/0.2 mA h cm−2 in symmetric cells. This anode-constructed PTCDA‖ Cu@Sb2O3@rGO@K full battery exhibits both exceptional cycling stability (over 2000 cycles) and outstanding rate capability (112.8 mA h g−1 at 10 C). Furthermore, even under extremely low temperature (−20 °C), this battery can still maintain an impressive 55% of its room temperature capacity. In situ Raman spectroscopic techniques and electrochemical methods including in situ EIS, half cell, symmetric cell, and full cell tests and theoretical DFT calculations are carried out to probe the structure–performance relationship and the reaction mechanisms for fundamental understanding toward further optimizing the performance of such the K anode and the corresponding KMBs. The strategy for stabilizing the K metal anode in this work may provide a guidance for further development of advanced low-temperature potassium metal batteries. [ABSTRACT FROM AUTHOR]

Abstract

Neural stem cell (NSC) transplantation exerts a therapeutic effect on spinal cord injury (SCI) but is limited to an unregulated differentiation pattern by which NSCs preferentially differentiate into astrocytes, with relatively few neurons. It is well established that the increased NSC-derived astrocytes exhibit aberrant axonal sprouting associated with allodynia-like symptoms of the forepaws. Some strategies have been used to overcome this issue, such as regulation of major pathways, ex vivogene transfer, and genetic overexpression. However, lack of efficiency, viral vector safety issues and the risk of tumorigenesis have hindered the clinical application of these treatments. Here, we show that astrocytic differentiation of NSCs in vitroand in vivocan be inhibited by encapsulation of cells in a three-dimensional chondroitin sulfate methacrylate (CSMA) hydrogel. When CSMA hydrogels were used to transplant NSCs, the combinatory implant promoted functional recovery and attenuated the hypersensitivity responses of the forepaws. Further analysis showed that transplantation of NSCs within CSMA hydrogels reduced injured cavity areas and promoted neurogenesis rather than fibroglial formation after graft implantation. Furthermore, the treatment prevented allodynia-related CGRP/GAP43-positive nociception due to fibers sprouting into inappropriate lamina regions. Taken together, these findings show that CSMA/NSCs combined transplantation helps prevent adverse side effects of NSCs treatment and promotes recovery of SCI.
