In many instances, tourism has begun to be perceived by touristic cities' residents as an important problem. We examine the phenomenon of antitourism and, in particular, the discourses of rejection and resistance against tourism in the city of Barcelona. Previous research has examined residents' attitudes and behaviors towards tourism development from both a cognitive and emotional aspect, but we still lack a more qualitative, in-depth understanding of residents' emotion discourses. Furthermore, for this research, a novel type of dataset has been analyzed-that is, discourses constructed in online media. In particular, the study was based on the analysis of the comment threads of news articles about the touristic impact on Barcelona. In total, 6,916 comments posted in online news articles were examined. This analysis also permitted to observe the interaction between two different actors, the media and the residents, and to see how residents respond to the media's framings about tourism in Barcelona.

High-voltage disordered spinel LiNi Mn O is a promising cathode material for high power density in lithium-ion batteries. However, it suffers from poor cycle life associated with the rock-salt phase transformation. This study presents a straightforward synthesis approach to enhance the electrochemical performance of LiNi Mn O through a synergistic solid-state modification with LiF and AlF . This dual modification promotes rapid Li⁺ diffusion, enables near-complete delithiation/lithiation, approaching the theoretical capacity of disordered LiNi Mn O , and, more importantly, effectively mitigates the formation of the rock-salt phase, thereby enhancing structural stability, as confirmed by operando X-ray absorption spectroscopy (XAS) and synchrotron X-ray diffraction (SXRD). As a result, the optimized LiNi Mn O  (10 mg AlF + 30 mg LiF) delivers high reversible capacities of 142.1, 139.1, 129.2, 121.6, 110.3, 93.5, and 76.1 mAh∙g at 0.2C, 0.5C, 1.0C, 2.0C, 3.0C, 4.0C, and 5.0C, respectively. Full cells using graphite as the anode and a high-loading cathode exhibit excellent cycling performance. They retain 80% of their capacity after 200 cycles at 0.5C within a voltage window of 3.5-4.9 V with cathode loading of 11 mg∙cm . The findings of this study will significantly advance high-power LiNi Mn O materials, offering improved battery life and thereby enhancing their potential for practical applications.

High-voltage disordered spinel LiNi0.5Mn1.5O4 is a promising cathode material for high power density in lithium-ion batteries. However, it suffers from poor cycle life associated with the rock-salt phase transformation. This study presents a straightforward synthesis approach to enhance the electrochemical performance of LiNi0.5Mn1.5O4 through a synergistic solid-state modification with LiF and AlF3. This dual modification promotes rapid Li⁺ diffusion, enables near-complete delithiation/lithiation, approaching the theoretical capacity of disordered LiNi0.5Mn1.5O4, and, more importantly, effectively mitigates the formation of the rock-salt phase, thereby enhancing structural stability, as confirmed by operando X-ray absorption spectroscopy (XAS) and synchrotron X-ray diffraction (SXRD). As a result, the optimized LiNi0.5Mn1.5O4 (10 mg AlF3 + 30 mg LiF) delivers high reversible capacities of 142.1, 139.1, 129.2, 121.6, 110.3, 93.5, and 76.1 mAh∙g-1 at 0.2C, 0.5C, 1.0C, 2.0C, 3.0C, 4.0C, and 5.0C, respectively.

They retain 80% of their capacity after 200 cycles at 0.5C within a voltage window of 3.5-4.9 V with cathode loading of 11 mg∙cm-2. The findings of this study will significantly advance high-power LiNi0.5Mn1.5O4 materials, offering improved battery life and thereby enhancing their potential for practical applications.High-voltage disordered spinel LiNi0.5Mn1.5O4 is a promising cathode material for high power density in lithium-ion batteries.
