Mesh polymer electrolytes for lithium polymer batteries

Lithium polymer batteries are promising power sources for a wide range of consumers from small appliances (mobile phones, laptops) to electric cars. There is a whole direction in the development of polymer electrolytes based on various polyester diacrylates, which form a three-dimensional grid that is amorphous in nature during radical polymerisation. In this work new solid polymer electrolytes based on polyester diacrylate with 2-hydroxyethylacrylate (PEDA) links modified by polyethylene glycol, its urethane-acrylate derivative, ethylene carbonate and TiO2 nanopowders have been synthesized. The effect of polymer electrolyte composition on its physico-chemical properties has been studied. Stable systems with high conductivity of 10(-3)÷10(-4) S/cm at room temperature up to 100º¿ are obtained. Quantum-chemical simulation of lithium ion transport in the investigated polymer systems was performed. Besides, PEDA usage perspectivity as binding materials for fluorocarbon cathodes was shown. This work will be of interest for specialists in the development of lithium-polymer current sources.
