基于区块链和通证经济的跨国跨洲电力市场机制设计

open access: yes智能科学与技术学报, 2019
全球能源互联网旨在构建以电力消费为核心的能源模式,跨国跨洲电力交易是推动其发展的必要条件和有效途径。首先分析跨国跨洲电力交易面临的问题,提出了基于区块链和通证经济的跨国跨洲电力市场设计思路。然后,将跨国跨洲电力市场的组成分为5个部分,并分别对这5个部分进行了描述与建模。最后,利用等比例放大的IEEE 39节点系统,对本文所提市场进行了仿真与分析。仿真结果表明,基于区块链和通证经济的跨国跨洲电力市场可以保证跨区域、多主体电力交易的有效实施,同时有利于激励发电商使用清洁能源参与电力市场。

Dual‐Phosphidation‐Engineered Ni/NiO Heterojunction Nanoflowers With Synergistic Surface PO43− Group and P Doping Sites for High‐Performance and Low Temperature (−40°C) Supercapacitors

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Nickel oxide (NiO)‐based electrodes with high theoretical specific capacitance can effectively increase the energy density of supercapacitors—the key factor limiting their practical deployment. However, several issues still restrict the production of advanced NiO‐based electrodes.

Interfacial Reconstruction of Li+ Solvation Shell for Fast Diffusion Kinetics in Low‐Temperature Dendrite‐Free Li Metal Battery Enabled by Atomic Catalysts

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Low‐temperature lithium‐metal batteries (LT‐LMBs) are increasingly pursued for higher energy density and extended cycle life, yet suffer from severely depressed interfacial Li+ desolvation/diffusion kinetics due to the enlarged solvation structures as well as organic electrolyte solidification, ultimately inducing much higher barriers to ...

Structural Modulation of Magnetic Softness in Fe‐Based Amorphous Alloys via Pulse Current Training

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Fe‐based amorphous alloys, despite their intrinsically low magnetocrystalline anisotropy, suffer from quasi‐dislocation dipoles and localized stress fields that impede domain‐wall motion and increase coercivity. Here, we introduce pulse current training (PCT) as an energy‐efficient technique to overcome these limitations in a Fe76Si9B10P5 ...
