Why is NiO a lithiophilic material?
Best insight from top research papers
NiO is considered a lithiophilic material due to its ability to guide the homogeneous and smooth deposition of metallic lithium, thus addressing issues like dendrite formation and volume change in lithium metal batteries. The lithiophilic nature of NiO reduces the nucleation barrier for lithium deposition, facilitating uniform plating. Additionally, the formation of a lithiophilic NiO layer on Ni surfaces enhances the wettability of molten lithium, leading to stable anode performance with no dendrite formation even after multiple cycles. Furthermore, the dynamic lithiation process of NiO nanoplates and nanoparticles reveals that NiO undergoes structural changes and breakdown during lithiation, hindering electron transportation due to the formation of Li2O, which impacts cycling performance. These characteristics make NiO a promising lithiophilic material for lithium battery applications.

Is there difference in Bulk bandgap and think film Bandgap of NiO?4 answersThe bandgap of Nickel Oxide (NiO) exhibits variations between bulk and thin film forms. Bulk NiO typically has an optical bandgap of around 4.3 eV, whereas thin films of NiO show a range of bandgap values influenced by factors like annealing temperature and solution molarity, with values between 3.66-3.83 eV. Additionally, the introduction of Fe doping in NiO thin films leads to a decrease in the optical band gap with increasing Fe concentration. Furthermore, the formation of nanoporous NiO films through hydrothermal techniques results in optical band gaps estimated at 3.86 and 4.51 eV, with the latter being significantly higher than that of bulk NiO, attributed to quantum confinement effects in nanocrystals within the film. These findings collectively highlight the differences in bandgap values between bulk and thin film NiO.

What is lithophilic plant?4 answersA lithophilic plant refers to a plant species that has an affinity for or is adapted to grow on rocky or stony substrates. These plants are able to thrive in harsh environments with limited soil and water availability. They have specialized adaptations such as deep root systems that can penetrate through rocks to access water and nutrients, as well as mechanisms to prevent water loss and withstand extreme temperatures. Lithophilic plants play an important role in stabilizing rocky slopes and preventing erosion. They can also contribute to the formation of soil by breaking down rocks and releasing minerals through weathering processes. The study of lithophilic plants is relevant in understanding plant adaptation to challenging environments and can have implications for ecological restoration and conservation efforts.
