How to improve the stability and rate performance of lithium-ion batteries with transition metal oxide anodes

Abstract

The lithium ion battery is the most promising battery candidate to power battery electric vehicles. For these vehicles to be competitive with those powered by conventional internal combustion engines, significant improvements in battery performance are needed, especially in the energy density and power delivery capabilities. Promising substitutes for graphite as the anode material include silicon, tin, germanium, and various metal oxides that have much higher theoretical storage capacities and operated at slightly higher and safer potentials. In this critical review, metal oxides-based materials for lithium ion battery anodes are reviewed in detail together with the progress which is made in my lab on that topic. Their advantages, disadvantages, and performance in lithium ion batteries are discussed through extensive analysis of the literature, and new trends in materials development are also reviewed. Two important future research directions are proposed and performed in my lab, based on results published in the literature: the development of composite and nanostructured metal oxides to overcome the major challenge posed by the high capacity of metal oxide anodes.

Data-Driven Studies of Li-Ion-Battery Materials

“…This selection of discharge rate has a significant effect on cell performance. Consider the work of Wang et al who demonstrated an increase in specific capacity of more than 100% when changing the discharge rate by an order of magnitude [42]. In other instances, researchers will report cyclic voltammograms, which require a data scientist to interpret voltage ranges by hand when retrieving the data.…”

Tin Nanoparticles Encapsulated Carbon Nanoboxes as High-Performance Anode for Lithium-Ion Batteries

“…Therefore, extensive researches of alloy-based materials (Si, Ge, Sn, etc.) have been studied in LIBs for the higher capacity of these anode materials (Obrovac and Chevrier, 2014 ; Li et al, 2017a ; Wang et al, 2017 , 2018 ; Zhang et al, 2018a ). Metallic Sn was reported with high theoretical capacity (997 mAh g −1 ), good electroconductibility and non-toxicity (Hassoun et al, 2007 ; Hu et al, 2008 , 2011 , 2012b ).…”

Baby Diaper‐Inspired Construction of 3D Porous Composites for Long‐Term Lithium‐Ion Batteries

“…can be combined with carbon‐rich molecules and then the templates are removed after carbonization . Coincidentally, it is equally wide concerned that transition metal oxides (TMOs) possessing high theoretical specific capacities with the layered structure for the favorable transmission of lithium ions (Li + ions) have been widely used . However, it also suffers from inferior cycle stability and poor rate capability because of their low conductivity and serious volume variation during lithiation/delithiation cycle, which would greatly restrict their development and application as a prospective anode in energy storage cells …”
