Relating the 3D electrode morphology to Li-ion battery performance; a case for LiFePO₄

One of the main goals in lithium ion battery electrode design is to increase the power density. This requires insight in the relation between the complex heterogeneous microstructure existing of active material, conductive additive and electrolyte providing the required electronic and Li-ion transport. FIB-SEM is used to determine the three...

Direct view on the phase evolution in individual LiFePO4 nanoparticles during Li-ion battery cycling

Phase transitions in Li-ion electrode materials during (dis)charge are decisive for battery performance, limiting high-rate capabilities and playing a crucial role in the cycle life of Li-ion batteries. However, the difficulty to probe the phase nucleation and growth in individual grains is hindering fundamental understanding and progress. Here...

A Template for Enhanced Lithium Ion Battery Electrodes

Dictated by exhausting sources of conventional fossil fuels, their irreversible damage on environment, international conflicts for oil resources – distressing global economy, worldwide research has focused towards developing alternate, but sustainable, sources of energy generation and storage to meet global energy demands and emission-free...
