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 …

Metal borohydrides as solid-state electrolytes

Storage of renewable energy is essential in order to create a new sustainable energy economy e.g. directly as electricity in a Li-battery or indirectly as hydrogen in a solid state metal hydride.1 Batteries are rechargeable but have moderate life time and limited energy storage capacity. Metal borohydrides can store considerable amounts of energy as hydrogen …

Procrystal analysis for easy visualization of Li pathways

The search for novel crystalline materials for use as electrodes in battery materials is a lengthy and costly process. There is a great need for a fast evaluation tool to supplement already existing experimental and theoretical methods. In this talk, the procrystal analysis is introduced as a fast technique for pointing out promising candidates for …
