The paper presents some results of computer simulations and density functional theory calculations of the energetic and structural characteristics of few-layer graphene nanostructures as storing cells for Li.Modeling and calculations allow to reveal some peculiarities in such systems, which can be considered as causes of known dimension instabilities and shortening of the life-time of Libased electrical power devices.Results of the computational study and calculations predict, that all these problems can be in significant measure solved by modifying of few-layer graphene nanostructures by bridge -like defects, which make them much more stiffer and stable against the deformation.
