Abstract:
Hollow microflower-shaped CoSe2 particles were successfully constructed and further evaluated as an anode material for sodium-ion batteries. It yielded a large discharge capacity of 220 mA h g-1 and ultralong cycle life of 1690 cycles at 1 A g-1. This ultralong cycle life can be attributed to a surface-controlled pseudocapacitive behavior and resulting rapid electron/sodium ion transport.

Ions as Acids and Bases
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:
