Elastic Framework Driven Mg2+ Autocapture and Autocatalysis: Mechanistic Origin of Fast Hydrogen Release in 2LiBH4–MgH2

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The protracted incubation time has long been the Achilles' heel of the promising 2LiBH4–MgH2 hydrogen storage system. Instead of the usual route‐creating heterogeneous nucleation sites to hasten MgB2 formation, we shortened both de‐ and re‐hydrogenation incubation periods by steering the Mg transformation itself.

区域电网分布式储能选址定容规划

open access: yesGaoya dianqi, 2020
分布式储能是解决新能源并网问题的有效手段,分布式储能的选址定容将影响储能系统效率、系统网损及投资成本等,因此有必要对分布式储能进行选址定容规划。文中提出一种分布式储能选址定容规划,具体策略是以电压稳定裕度为指标,选出部分系统电压稳定性弱的节点,进行预选址;然后在考虑储能设备充放电状态的基础上,针对负荷日特性曲线,设定储能系统的调度策略;并考虑负荷、风电、光伏时序特性,以有功网损为目标函数,利用粒子群算法寻优,优化储能充放电功率;最终确定分布式储能设备的位置及容量 ...

MXene‐Based Materials Contribute Better Alkali Metal–Chalcogen Batteries: Progress, Challenges, and Perspectives

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Alkali metal–chalcogen batteries (AMCBs) are one of the most promising next‐generation energy storage systems because of their high energy density and reasonably low cost. However, the practical application of AMCBs is severely hindered by the volume expansion of the chalcogen cathode, the shuttle effect of polychalcogenides, and unstable ...
