The cathode material derived from Na0.5VPO4.8F0.7 is demonstrated to reversibly accommodate a large amount of Ca2+ ions, forming a series of CaxNa0.5VPO4.8F0.7 (0 < x < 0.5) phases without any noticeable structural degradation. The robust framework enables one of the smallest volume changes (1.4%) and the lowest diffusion barriers for Ca2+ among the cathodes reported to date, offering the basis for the outstanding cycle life and power capability.

This unique property enables lithium/fluorinated graphite batteries with MPM-based electrolytes to deliver a significantly higher capacity than those with commercial separator membranes (~500 mAh g−1 vs. <0.03 mAh g−1) at −40 °C under reduced pressure of the electrolyte.
![[Nature Communications] Layered double hydroxide membrane with high hydroxide conductivity and ion selectivity for energy storage device](http://beyond-battery.com/cdn/shop/articles/naturecomm_400x.jpg?v=1623142028)
The LDHs-based membrane enables an alkaline zinc-based flow battery to operate at 200 mA cm−2, along with an energy efficiency of 82.36% for 400 cycles. This study offers an in-depth understanding of ions transport in LDHs and further inspires their applications in other energy-related devices.
![[NATURE] Tetradiketone macrocycle for divalent aluminium ion batteries](http://beyond-battery.com/cdn/shop/articles/060521_blog_nature3_400x.jpg?v=1620279574)
Researchers from Seoul National University, Gwanak-Gu, Seoul, Republic of Korea, reported on the use a novel Aluminium ion battery cathode material that could overcome the frustration of not fully utilizing metallic Aluminium's low cost and high air stability.
