3D Tomographic Measurements And Simulations Of Li-Ion Battery Positive Electrodes

This talk reviews the use of focused ion beam – scanning electron microscopy (FIB-SEM) and transmission X-ray microscopy (TXM) to obtain three-dimensional tomographic images of commercial lithium-ion battery electrodes such as LiFePO4, LiCoO2, and LiCoO2/Li(Ni1/3Mn1/3Co1/3)O2 composite.  After briefly reviewing the measurement techniques, the structural results are described, including imaging of both oxide and carbon phases. …

Lithium insertion/extraction kinetics in LiFePO4

The electric vehicle appears to be the new frontiers in lithium batteries. Distinctly different from mass produced microelectronics, it requires higher energy density as well as improved power performance requirements. Especially, charge/discharge rates during startup from standstill, deceleration, emergency charging, etc. provide unique challenges. To this end, new chemistries and new material with morphologies like …

Atomic layer deposition in a battery perspective

The Atomic Layer Deposition technique is especially suited for formation of conformal coating of pinhole free films on surfaces with complex geometrical shapes, an architecture most commonly adopted for micro battery designs. Realization of all solid state Li-ion microbatteries should therefore be close at hand, however, no fully functional all solid state ALD-type battery is …

In situ synchrotron XRD on a capillary Li-O2 battery

In situ studies give an opportunity to explore systems with a minimum of external interference. As Li-air batteries hold the promise for a future battery technology the investigation of the discharge and charge components of the cathode and anode is of importance, as these components may hold the key to making a large capacity rechargeable …

In situ study of hydrothermal formation of spinel type LiMn2O4 nanocrystals

Solvothermal reactions have been shown to be a good way to synthesize nanocrystalline materials. Many properties of the product, such as phase composition, crystallite size, morphology and crystallinity, can be controlled by changing and controlling synthesis conditions, such as reaction temperature, heating rate, reaction time, precursor concentration and pH. Ex situ investigation of the effect …

Degradation of LFP-based Battery System used for Primary Frequency Regulation

Lithium-ion batteries have developed into a popular energy storage choice for a wide range of applications because of their superior characteristics in comparison to other energy storage technologies. Besides modelling the performance behaviour of lithium-ion batteries, it has become of huge interest to accurately estimate their degradation because of both economic and technical considerations. The …

Unlocking the Potential of Cation-Disordered Oxides for Rechargeable Lithium Batteries

In today’s lithium batteries, those cathodes are usually made of an orderly crystalline material, sometimes in a layered structure. When slight deviations from that perfect order are introduced, the battery’s efficiency generally goes down — so disordered materials have mostly been ignored in the search for improved battery materials.
