Electrical energy storage devices have a key role in future world and supercapacitors are an attractive option in this domain. Supercapacitors are much better than today's lithium-ion batteries in some features such as rate of charge and discharge (power density), life and thermal performance but they are much heavier, bulkier and more expensive compared to lithium batteries. Research on supercapacitors is being pursued and it is likely that advanced supercapacitors with enhanced energy density be commercialized in near future.

Advances in energy storage technologies have affected many aspects of today's world. Among many available technologies in energy storage field, lithium-ion batteries could grow rapidly and widespread into many applications because of their sophisticated features. However experts predict that this technology is approaching its limits and more improvements will be difficult or impossible to achieve in coming years.

Population is one of the components of power. Also, suitable distribution of a population is one of the main factors in balancing many areas within the country, especially for countries with a large area of land. The report studies the population policies of the Russian Federation. One of the main pillars of this study is to outline the main policy of increasing population in Russia. These policies have led to an increase in the population growth rate after about two decades of decline.
