Thanks to their high energy density, light weight and long cycle life, rechargeable lithium ion batteries (LIBs) have become one of the dominant power sources for portable electronic devices. With the growing need for higher capacity and safety, numerous efforts have been made to develop alternative high-performance electrode materials for next-generation LIBs. As an example, the anode electrod...
Due to electrical properties (high electron mobility) and electrochemical characteristics (high electron transport rate), graphene-based materials have been widely applied for various scientific fields. However, due to their two-dimensional structures, these materials have low active sites for reaction. Therefore, changing from two-dimensional sheets dimensional to the three-dimensi...
Spinel Li4Ti5O12 (LTO) and reduced graphene oxide (rGO) are attractive anode materials for lithium-ion batteries (LIBs) because of their unique electrochemical properties. Herein, we report a facile one-step hydrothermal method in preparation of a nanocomposite anode consisting of well-dispersed mesoporous LTO particles onto rGO. An important reaction step involves glucose as a novel linker age...
In this work, we describe a simple 1-mask sacrificial layer process that allows us to prototype a tuneable capacitor. The process is specially optimized to procure a dual picks profile of the sacrificial layer. The geometry design and the influence of the structural material stress were considered through the finite element analysis. The FEM simulation with Ansys was used to study in detail pro...
This work reports on the synthesis of rare earth-doped Li₄Ti₅O12 nanosheets with high electrochemical performance as anode material both in Li half and Li₄Ti₅O12/LiFePO₄ full cell batteries. Through the combination of decreasing the particle size and doping by rare earth atoms (Ce and La), Ce and La doped Li₄Ti₅O12 nanosheets show the excellent electrochemical performance in terms of high speci...
Large-area phosphorus-doped carbon nanosheets (P-CNSs) are first obtained from carbon dots (CDs) through self-assembly driving from thermal treatment with Na catalysis. This is the first time to realize the conversion from 0D CDs to 2D nanosheets doped with phosphorus. The sodium storage behavior of phosphorus-doped carbon material is also investigated for the first time. As anode material for ...
