Book Synopsis From Intrinsic to Extrinsic Design of Lithium-Ion Battery Layered Oxide Cathode Material Via Doping Strategies by : Chul-Ho Jung
Download or read book From Intrinsic to Extrinsic Design of Lithium-Ion Battery Layered Oxide Cathode Material Via Doping Strategies written by Chul-Ho Jung and published by Springer Nature. This book was released on 2022-10-20 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the comprehensive understanding of Ni-rich layered oxide of lithium-ion batteries cathodes materials, especially focusing on the effect of dopant on the intrinsic and extrinsic effect to its host materials. This book can be divided into three parts, that is, 1. overall understanding of layered oxide system, 2. intrinsic effect of dopant on layered oxides, and 3. extrinsic effect of dopant on layered oxides. To truly understand and discover the fundamental solution (e.g. doping) to improve the Ni-rich layered oxides cathodic performance, understanding the foundation of layered oxide degradation mechanism is the key, thus, the first chapter focuses on discovering the true degradation mechanisms of layered oxides systems. Then, the second and third chapter deals with the effect of dopant on alleviating the fundamental degradation mechanism of Ni-rich layered oxides, which we believe is the first insight ever been provided. The content described in this book will provide research insight to develop high-performance Ni-rich layered oxide cathode materials and serve as a guide for those who study energy storage systems.

Book Synopsis Enhancing Electrochemical Performance of Electrode Materials for Li-ion Batteries and Na-ion Batteries Via Thermodynamic Surface/Interface Contro by : Jiajia Huang
Download or read book Enhancing Electrochemical Performance of Electrode Materials for Li-ion Batteries and Na-ion Batteries Via Thermodynamic Surface/Interface Contro written by Jiajia Huang and published by . This book was released on 2017 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: A facile and low-cost route based on thermodynamic principles of surface amorphous films (SAFs), intergrainular films (IGFs), and cation surface segregation benefits electrochemical performances of electrode materials for lithium-ion batteries and sodium-ion batteries. SAFs as a facile and generic surface modification method is utilized to significantly improve the rate performance and cycling stability of cathode materials for lithium-ion batteries. A thermodynamic framework of SAFs is proposed. These nanoscale SAFs form spontaneously and uniformly upon mixing and annealing at a thermodynamic equilibrium, and they exhibit a self-regulating or "equilibrium" thickness due to a balance of attractive and repulsive interfacial interactions acting on the films. Specially, spontaneous formation of nanoscale Li3PO4-based SAFs has been demonstrated in two proof-of-concept systems LiCoO2 and LiNi0.5Mn1.5O4. Furthermore, SAFs introduced by nitridation can also benefit the performance of TiO2 anode material for sodium-ion batteries. The amorphous intergrainular films (IGFs) are found in the system of Sn doped Si anode for lithium-ion batteries. The coexistence of IGFs and porous secondary structure (characterized by FIB/SEM on the cross section) results in an enhanced performance. SAFs and IGFs can be used to guide future experiments of other material systems. Utilizing anisotropic surface segregation to thermodynamically control the particle morphology and the surface composition is another economic, facile, and effective method to significantly improve the electrochemical performance of battery electrodes. WO3 doping and anisotropic surface segregation can change the facet relative surface energy to tailor the particle Wulff shape of LiMn1.5Ni0.5O4 spinel materials and the surface Mn/Ni ratio and benefits performances. The WO3 surface segregation can also improve Co-free Li-rich layered oxide Li1.13Ni0.3Mn0.57O2 cathode material performance. X-ray photoelectron spectroscopy in conjunction with ion sputtering has shown that W segregates to the particle surfaces and decreases the surface Ni/Mn atomic ratio; high-resolution transmission electron microscopy has further suggested that the segregation of W increases the structural disorder at the particle surfaces, which may also benefit the rate performance.
Book Synopsis Cathode Electronic Structure Impact on Lithium and Sodium Batteries Parameters by : Janina Molenda
Download or read book Cathode Electronic Structure Impact on Lithium and Sodium Batteries Parameters written by Janina Molenda and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author of this work basing on her own investigations of AxMO2 cathode materials (A¬†=¬†Li, Na; M¬†=¬†3d) has demonstrated that the electronic structure of these materials plays an important role in the electrochemical intercalation process. The proposed electronic model of intercalation is universal and has outstanding significance with regard to tailoring the properties of electrode materials to the most efficient application in Li-ion and Na-ion batteries. The paper reveals correlation between electronic structure, transport, and electrochemical properties of layered LixCoO2, LixNi1,àíy,àízCoyMnzO2 and NaxCoO2 cathode material and explains of apparently different character of the discharge/charge curve in LixCoO2 (monotonous curve) and NaxCoO2 systems (step-like curve). Comprehensive experimental studies of physicochemical properties of LixNi1,àíy,àízCoyMnzO2 cathode material (XRD, electrical conductivity, and thermoelectric power) are supported by electronic structure calculations performed using the Korringa-Kohn-Rostoker method with the coherent potential approximation (KKR-CPA) to account for chemical disorder. It is found that even small oxygen defects (~1%) may significantly modify DOS characteristics via formation of extra broad peaks inside the former gap leading to its substantial reduction.
