There have been unprecedented research efforts to produce efficient and sustainable electrode materials for lithium-ion batteries (LIB). The research efforts to increase energy density, life cycle, safety, and rate-capability are still in progress. This work is carried out to explore the prospects of a new anode material CrGeTe3 for use in LIB stud...
Lithium Metal Batteries (LMBs) pose themselves as a key contender to increasing the energy density and specific energy of Lithium Ion Batteries (LIBs). This would both decrease cost and increase scope of application and versatility for LIBs across a range of weight and volume sensitive applications. However, lithium dendrite growth poses a key obst...
Herein, novel single-crystalline Ge nanotetrahedrons with dominantly exposed (102) facets are synthesized via a liquid-phase chemical reduction strategy. Polyvinyl pyrrolidone is innovatively employed to mediate the product morphology, while the reaction time also plays a significant role. As the anode materials for lithium ion batteries, the nanos...

Recently, various electrolyte additives are used to reduce the negative impact on high voltage performance of the nickel-rich cathode (LiNixCoyMn1-x-yO2) (x >= 0.6). In this work, a selected additive, methyl diphenylphosphonate (MDPO), is applied to Li/LiNi0.8Co0.1Mn0.1O2(NCM811) half cells operating at high work voltages of 2.8-4.5 V. The electroc...
Lithium Ion Batteries (LIBs) are important in today's society, powering cars and mobile devices. LIBs consist of a negative anode commonly made of graphite, and a positive cathode commonly made from transition metal oxides. Between these electrodes are separators and organic solvent based electrolyte. Due to the high potential of LIBs the electroly...
Graphene oxide is a promising nanomaterial due to its surface versatility by substitution of functional groups and controllable d-spacing. However, most common methods to prepare graphene oxide are based on chemical exfoliation by strong oxidation agents forming small flake dispersions that are used to form thin films of aggregatedflakes. These met...

We report a novel computational simulation study of the performance of Lithium Ion Battery (LIB) NMC electrodes for different compositions. The novelty of this work relies on the explicit consideration with three-dimensional resolution of the Active Material (AM) and the Carbon-Binder Domains (CBD) resulting from simulations of the electrode manufa...
Non-uniform distribution of current density and temperature is inevitable especially in high C-rate and it can lead to bad performance of battery. Therefore, the non-uniform effect (non-uniform temperature, current density and aging) on the pouch battery performance is studied with experiment and simulation. A new method, which measures the direct ...
