Sumario:This work reports the synthesis of a new quasi two-dimensional layered compound, K(0.36)(H(2)O)(y)WS(2), for aqueous potassium ion storage. Its crystal structure determined by single crystal X-ray diffraction is composed of WS(2) layers and disordered hydrated K(+) stacking along the c direction alternately. Due to the large interlayer spacing and high conductivity, K(0.36)(H(2)O)(y)WS(2) is demonstrated to be a stable host for reversible intercalation and de-intercalation of hydrated K(+) in K(2)SO(4) aqueous solution.
