Can porous materials be used in Li-O 2 battery systems?

Finally, the rational design and innovative directions of porous materials are provided for their development and application in Li–O 2 battery systems. The authors declare no conflict of interest. Advanced Materials, one of the world's most prestigious journals, is the home of choice for best-in-class materials science for more than 30 years.

What is the porosity of positive electrodes in lithium-ion batteries?

Herein, positive electrodes were calendered from a porosity of 44–18% to cover a wide range of electrode microstructures in state-of-the-art lithium-ion batteries.

What is the porosity of polyolefin separator for rechargeable batteries?

The porosity of the polyolefin separator for rechargeable batteries is normally between 40% and 50% [55, 56]. The methods in controlling the porosity of separators generally include direct weighing, microscopic analysis, vacuum impregnation, soaking medium and floating [57, 58].

Why is porosity important for battery cell performance?

The porosity of the positive electrode is an important parameter for battery cell performance, as it influences the percolation (electronic and ionic transport within the electrode) and the mechanical properties of the electrode such as the E-modulus and brittleness [4, 5, 6, 7, 8].

Can a non-porous separator increase lithium-ion battery capacity?

What is a non-flexible Li-ion battery?

Non-flexible, commercialised Li-ion batteries (LIBs) have specific energy densities in the range of ~200–285 Wh kg −1 depending on cell chemistry 2, 3, 4, 5, 6, 7, 8, 9, 10. Electrodes are basically metallic (Al or Cu) current collectors (CCs) with slurry-cast active coatings which are unsuitable for repeated mechanical deformation.
