Electrode materials for lithium-ion batteries
The constraints of the electrolyte stability window heighten the importance of the second term in the energy density equation, specific capacity (C sp).Specific capacity is an empirical value which is correlated to the theoretical capacity, C theor, defined by (3) C t h e o r = n F M W where n is the number of electrons stored in a mole of active material, …
Carbon dots (CDs), an emerging class of carbon materials, hold a promising future in a broad variety of engineering fields owing to their high diversity in structure, composition and properties. Recently, their potential applications have spanned from bio-imaging, fluorescent probing and catalysis, to energy
Main Text As population demands for freshwater increase, existing natural freshwater resources face significant strains. Currently, over 2.5 billion people live in localities that are subject to severe water scarcity at least 1 month of the year. 1 Scarcity affects all types of localities, such as urban, rural, coastal areas, landlocked areas, and off …
Electrode Degradation in Lithium-Ion Batteries | ACS Nano
1 Introduction Recently, devices relying on potassium ions as charge carriers have attracted wide attention as alternative energy storage systems due to the high abundance of potassium resources (1.5 wt % in the earth''s crust) and fast ion transport kinetics of K + in electrolyte. 1 Currently, owing to the lower standard hydrogen potential …
