Utilizing dual functions of LaPOto enhance the electrochemical performance of LiNiCoAlOcathode material.

In this paper, via a facile wet coating method, the LaPOcoating layer has been introduced onto the LiNiCoAlO(NCA) surface while a small part of Lahas also been doped on the surface to realize the dual functions modification of coating and doping. The morphology and structure of the samples were investigated by XRD, SEM and TEM measurements. The chemical compositions of the samples were analyzed via EDS and XPS data.

Face-lifting the surface of LiNiCoAlOcathode via Y(PO)to form antriple composite Li-ion conductor coating layer with the enhanced electrochemical performance.

Due to the assets such as adequate discharge capacity and rational cost, LiNiCoAlO(NCA), a high-nickel ternary layered oxide, is regarded to be a favorable cathode contender for lithium-ion batteries. However, the superior commercial application is restricted by the surface residual alkaline lithium salt (LiOH or/and LiCO) of nickel-rich cathode materials, which will expedite the disintegration of the structure and the engendering of gas (CO). Therefore, in this paper, we devise and fabricate a Y(PO)modified LiNiCoAlO(NCA), intending to optimize the surface residual alkaline lithium salt (antecedent deportation of HO and CO) while forming antriple composite Li-ion conductor coating (Y(PO)-LiPO-YPO) to enhance the electrochemical behavior.

Dual functions of zirconium metaphosphate modified high-nickel layered oxide cathode material with enhanced electrochemical performance.

High-nickel LiNiCoO cathode shows an enormous potential in next-generation high energy density lithium-ion batteries. However, its cation mixing and the second hexagon to the third hexagonal of phase transition (H2 - H3) pose severe challenges to its practical and commercial applications. In this work, zirconium metaphosphate is applied to optimize the microstructure near surface zone of LiNiCoO cathode material to suppress its cation mixing and the H2 - H3 phase transformation during long cycling process.

Oxygen Vacancies of CeO Nanospheres by Mn-Doping: An Efficient Electrocatalyst for N Reduction under Ambient Conditions.

The electrochemical N reduction reaction (NRR) demonstrates a process of NH synthesis from N molecules under ambient conditions, which is environmentally friendly and recyclable. However, it requires an efficient electrocatalyst to activate inert N molecules, which is still difficult to satisfy. Recently, as an active NRR electrocatalyst and a typical metal oxide, CeO has featured ultrahigh thermal stability and the ability to apply heteroatom doping, which is an imperative approach importing oxygen vacancy by replacing metal ions with selective elements to greatly influence the activity of catalysts.

Optimizing surface residual alkali and enhancing electrochemical performance of LiNiCoAlOcathode by LiHPO.

LiNiCoAlO(NCA), a promising ternary cathode material of lithium-ion batteries, has widely attracted attention due to its high energy density and excellent cycling performance. However, the presence of residual alkali (LiOH and LiCO) on the surface will accelerate its reaction with HF from LiPF, resulting in structural degradation and reduced safety. In this work, we develop a new coating material, LiHPO, which can effectively optimize the residual alkali on the surface of NCA to remove HO and COand form a coating layer with excellent ion conductivity.

An Approach to Segment and Track-Based Pedestrian Detection from Four-Layer Laser Scanner Data.

Pedestrian detection is a critical perception task for autonomous driving and intelligent vehicle, and it is challenging due to the potential variation of appearance and pose of human beings as well as the partial occlusion. In this paper, we present a novel pedestrian detection method via four-layer laser scanner. The proposed approach deals with the occlusion problem by fusing the segment classification results with past knowledge integration from tracking process.
