Magnetron sputtering of platinum on nitrogen-doped polypyrrole carbon nanotubes as an efficient and stable cathode for lithium-carbon dioxide batteries.

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.

Promoting the Performance of Li-CO Batteries via Constructing Three-Dimensional Interconnected K Doped MnO Nanowires Networks.

Nowadays, Li-CO batteries have attracted enormous interests due to their high energy density for integrated energy storage and conversion devices, superiorities of capturing and converting CO. Nevertheless, the actual application of Li-CO batteries is hindered attributed to excessive overpotential and poor lifespan. In the past decades, catalysts have been employed in the Li-CO batteries and been demonstrated to reduce the decomposition potential of the as-formed LiCO during charge process with high efficiency.

High-Performance Lithium-Rich Layered Oxide Material: Effects of Preparation Methods on Microstructure and Electrochemical Properties.

Lithium-rich layered oxide is one of the most promising candidates for the next-generation cathode materials of high-energy-density lithium ion batteries because of its high discharge capacity. However, it has the disadvantages of uneven composition, voltage decay, and poor rate capacity, which are closely related to the preparation method. Here, 0.
