“…As the most successful energy storage devices, lithium-ion batteries (LIBs) have been widely used in our daily life, including electric vehicles and wearable electronic devices; thus, they have been well recognized by the 2019 Nobel Prize in Chemistry. However, LIBs faced a huge challenge for the use in the grid-scale energy storage with massive production because of the flammable electrolyte and high cost. Recently, several types of rechargeable batteries have the potential to be used for electricity grid systems, which are sodium-ion batteries, , potassium-ion batteries, and various aqueous batteries. Considering the price and safety, the aqueous rechargeable metal-ion batteries should be a better choice for grid-scale energy storage. Among the various aqueous batteries, aqueous zinc-ion batteries (ZIBs) have been regarded as one of the most hopeful candidates because the zinc anode exhibits a high theoretical capacity (820 mA h g –1 ), a lower redox potential (0.76 V vs standard hydrogen electrode), and highly reversible plating/stripping in the mild electrolyte.…”

“…Entre 30 °C e 150 °C é observada uma pequena perda de massa (A ≅ 4%) devido à desidratação e evaporação dos compostos orgânicos voláteis presentes nas amostras (BRADHA et al, 2015;HENAO et al, 2019). Duas perdas de massa maiores também são observadas entre 300 °C e 600 °C (B ≅ 17% e C ≅ 50%) devido a oxidação de compostos orgânicos derivados do etileno glicol, ácido cítrico e do nitrato presentes no método de síntese (BRADHA et al, 2015;HENAO et al, 2019). Para os precursores dos catalisadores LTM25O e LTM50O, pode-se observar o aparecimento de um ombro na perda de massa C, que aumenta junto com o teor de Mg nas amostras.…”

“…Observa-se que o espectro coletado na maior temperatura de análise ainda apresenta diversas bandas relacionadas ao CO2 quimissorvido, para todas as amostras, devido aos sítios básicos fortes, de acordo com os dados de DTP-CO2. BRADHA et al, 2015) Além disso, as curvas da Figura 22 apresentam padrões similares aos das análises da Figura 14 (TG/DTG das amostras substituidas no sítio B), com o mesmo perfil de perda de massas, subdivididos em 4 regiões (A ≅ 5%, B ≅ 25%, C ≅ 15% e D ≅ 20%) (HERRERA; JIMÉNEZ-MIER; CHAVIRA, 2014;BRADHA et al, 2015;HENAO et al, 2019;SILVA et al, 2019). Entretanto, pode-se observar uma inversão das intensidades relativas das regiões de perda de massa B e C em ambas as figuras.…”
