Highly activated oxygen redox enabling large-capacity Li-rich layered manganese-based oxide cathodes.

Li-rich Mn-based layered materials are considered the most promising next-generation high-energy-density cathode materials due to their high capacity, but their large irreversible capacity loss and severe voltage attenuation hinder their practical application. The limited operating voltage also makes it difficult to satisfy the increasing demand of high energy density in future applications. Inspired by the high voltage platform of Ni-rich LiNiCoMnO, we design and prepare a LiNiCoMnO (LLMO811) cathode material with increased Ni content the acrylic acid polymerization method and regulate the amounts of excess lithium of LLMO.

As an emerging green energy storage and conversion system, rechargeable Li-CO batteries have undergone extensive research due to their ultra-high energy density and their significant role in greenhouse gas CO conversion. However, current Li-CO batteries have some shortcomings that severely limit their large-scale application. The most critical problems involve the insulation of the discharge product LiCO and the slow decomposition kinetics, meaning that the battery generates a large overpotential and has a low cycle life, so the rational design of an efficient cathode catalyst is imperative.

Cadmium (Cd), a highly toxic heavy metal, adversely affects human and animal health. Quercetin (Que) is a kind of flavonoid that can protect many tissues from the toxic effect of heavy metals.

Submicron-Sized Nb-Doped Lithium Garnet for High Ionic Conductivity Solid Electrolyte and Performance of Quasi-Solid-State Lithium Battery.
