Accessing lithium−oxygen battery discharge products in their native environments via transmission electron microscopy grid electrode

High-fidelity and facile ex situ transmission electron microscopy (TEM) characterization of lithium−oxygen (Li−O₂) batteries is still limited by challenges in preserving the native environment of Li−O₂ discharge products. The extreme reactivity and moisture sensitivity of the discharge products means that they are...

Immersion precipitation route towards high performance thick and flexible electrodes for Li-ion batteries

Enabling the transition to renewable power sources requires further optimization of batteries in terms of energy/power density and cost-effectiveness. Increasing the practical thickness of Li ion battery electrodes not only can improve energy density on cell level but reduces manufacturing cost. However, thick electrodes exhibit sluggish...
