TL;DR: A low cost, safe aqueous Ca-ion battery based on low potential, lower specific weight in-situ polymerized polyaniline as an anode and a high redox potential open framework structured potassium copper hexacyanoferrate as a cathode is demonstrated and makes the battery a promising candidate for grid-scale storage applications.

TL;DR: Sodium-ion battery (NIB) cathode performance based on ammonium vanadate is demonstrated here as having high capacity, long cycle life and good rate capability, and density functional theory calculation is envisioned for the NH4V4O10 cathode.

TL;DR: In this article, a stable (4000 cycles), high capacity (237 ǫ g−1) and high rate capable hydrogenated metal-doped sodium titanium oxide (Na2Ti3O7) anode material for SIBs and that suffers from high 1st cycle irreversible loss (53.86%) initially.

TL;DR: In this article, the authors reported an ultrahigh specific discharge capacity (∼342 mA h g−1 at 0.1 A g− 1 current rate) and excellent electrochemical performance of a doped ammonium vanadium oxide (NVO) cathode.

TL;DR: In this article, the authors reported a new route to store/chemisorb high content of hydrogen on graphene by employing Benkeser reaction, which overcomes the liquid ammonia handling and produced multiple layer of graphene attached to the hydrogen atoms.
