TL;DR: New strategies are needed for batteries that go beyond powering hand-held devices, such as using electrode hosts with two-electron redox centers; replacing the cathode hosts by materials that undergo displacement reactions; and developing a Li(+) solid electrolyte separator membrane that allows an organic and aqueous liquid electrolyte on the anode and cathode sides, respectively.

TL;DR: By a novel in situ chemical vapor deposition, activated N-doped hollow carbon-nanotube/carbon-nanofiber composites are prepared having a superhigh specific Brunauer–Emmett–Teller (BET) surface area and total pore volume, which makes it a superior anode material for a Li-ion battery.

TL;DR: A simple method to remove Li2CO3 and the protons in the garnet framework is introduced by reacting garnet with carbon at 700 °C and the amount of the Li-Al-O glass phase with a low Li-ion conductivity in the grain boundary on the Garnet surface was reduced.

TL;DR: In this paper, the authors present a host framework into which the mobile cation is inserted reversibly over a finite solid-solution range, which is defined as the range of reversible cation insertion.

TL;DR: In this paper, the authors studied the cathode/electrolyte interface between LiCoO2 and Li7La3Zr2O12 (LLZO), and found that the high-temperature process to fuse LiCo2 and LLZO induced cross-diffusion of elements and formation of the tetragonal lithium phase at the interface.
