Peradeniya, 2002) Jayathilaka, P.A.R.D.; Dissanayake, M.A.K.L.; Albinsson, I.; Mellander, B.E.Item Electrical relaxation in some peo-based solid polymer elctrolytes(University of Peradeniya. Peradeniya, 2002) Bandara, L.R.A.K.; Dissanayake, M.A.K.L.Item Solid state electrochemical cells based on PEO-Mg(ClO4)2 polymer electrolyte and Mg/Cu electrodes(University of Perdeniya. Peradeniya, 1999) Bandara, L.R.A.K; Dissanayake, M.A.K.L.; Careem, M.A.; Amalashwaran, V.Item Solid polymer elctrolytes based on natural rubber and poly(ethelene) oxide (PEO) and their application in rechargeable Lithium batteries(University of Peradeniya. Peradeniya, 1997) Dissanayake, M.A.K.L.; Samantha, W.A.; Bandara, H.M.N.Hybrid solid electrolyte films have been prepared by incorporating various proportions of natural rubber into (PEO)9-LiCF3SO3 solid polymer electrolyte. Rubbery electrolyte membranes with as much as 50% by weight of natural rubber could be prepared without significantly reducing the ionic conductivity of the polymer electrolyte. The possibility of using these electrolyte membranes in solid state lithium batteries with V6O13 cathode has been demonstrated.Item Ionic conductivity of the Na2SO4-Na2WO4 system(University of Peradeniya. Peradeniya, 1995) Sumathipala, H.H.; Dissanayake, M.A.K.L.; Careem, M.A.; Bandaranayake, P.W.S.K.In this study, the electrical conductivity of the Na2SO4-Na2WO4 system has been measured using complex impedance technique to investigate the effect of anion substitution on the cationic conductivity. In the Na2SO4(I) based solid solubility region the conductivity increases as SO4 ions are substituted by WO4 in the crystal structure. Maximum conductivity of 4x10-4 Scm-1 with an activation energy 0.5 eV at 450oC has been observed around 22 mol% Na2WO4. The secondary conductivity maximum observed at 48 mol % Na2WO4 could be associated with a two-phase mixture consisting of Na2SO4 based and Na2WO4 based solid solutions.Item Determination of electrochemical stability window of a polyacrylonitrile based polymer system for different electrodes(2008) Perera, K.; Vidanapathirana, K.P.; Dissanayake, M.A.K.L.Item Artificial muscles based on Polyacrylonitrile based polymer electrolyte(2007) Perera, K.; Vidanapathirana, K.P.; Dissanayake, M.A.K.L.Item Conductivity variation of the liquid electrolyte, EC : PC : LiCF3SO3 with salt concentration(2006) Perera, K.; Dissanayake, M.A.K.L.
