The important role of thesis These days the seriousness surrounding and pertaining to the-renewable energy crisis can cause exploited demands to the surrounding ecosystems leading to depletion pollution and climate change including the alarming negative effects such as eroded environments. For these reasons renewable energy should be increasingly promoted and developed further development and research such as solar wind and tide thereby reducing our reliance on fossil fuels and the depletion of crucial ecosystems. However these resources have huge disadvantages that are intermittent and dependent on conditional factors related to the climate so using them poses many challenges for its application. Therefore solving these problems requires the creation of efficient energy storage devices for the development of renewable energy transferred from chemical energy to electrical energy. This is an important role and strategy toward the improvement of renewable energy for global solutions. Since the
