Supercapacitor energy storage battery
Nowadays, the energy storage systems based on lithium-ion batteries, fuel cells (FCs) and super capacitors (SCs) are playing a key role in several applications such as power generation, electric vehicles, computers, house-hold, wireless charging and industrial drives systems. Moreover, lithium-ion batteries and FCs are superior in terms of high energy density (ED) as compared to the SCs. But, the down-side associated with them is the low power density (PD). O. Nowadays, the energy storage systems based on lithium-ion batteries, fuel cells (FCs) and super capacitors (SCs) are playing a key role in several applications such as power generation, electric vehicles, computers, house-hold, wireless charging and industrial drives systems. Moreover, lithium-ion batteries and FCs are superior in terms of high energy density (ED) as compared to the SCs. But, the down-side associated with them is the low power density (PD). On the other hand, this high PD feature is essential for the enhancement of dynamic performance of the system. Therefore, the SCs are well utilized due to their dominant features such as high specific power, rapid charging-discharging rate and superior cycling life. Hence, this paper mainly focuses on the advancements of various types of SCs along with their performance improvement methods. The important properties and selection of the electrode and electrolyte materials are described in detail. The commercially available SCs are enumerated with much more emphasis on their Figure of Merits (FOMs). Furthermore, the prominent role of SCs is highlighted with respect to the aforementioned applications. Finally, the future challenges associated with the SCs are presented. This review paper gives insightness for the design engineers and researchers in order to fill the research gaps associated with the SCs.••••It presents an overview on different types of SCs along with the electrode materials and electrolytes.••It emphasizes the various performance enhancement approaches of the SCs.••It focuses on the Figures of Merits (FOMs) of the commercially available SCs.••It spotlights the important features and role of SCs in various eminent applications.••It highlights the various research hotspots and future perspectives of the SCs.Energy storageSuper capacitorsMaterialsApplicationsEnergy storage systems (ESS) are highly attractive in enhancing the energy efficiency besides the integration of several renewable energy sources into electricity systems. While choosing an energy storage device, the most significant parameters under consideration are specific energy, power, lifetime, dependability and protection. On the other hand, the critical performance issues are environmental friendliness, efficiency and reliability. The majority of our energy demands are fulfilled by the fossil fuels, which are extremely detrimental to the environment. The renewable energy sources like solar and wind energy are very clean and abundant. However, it is difficult to grab optimal power from these power sources due to the unpredictable operating conditions. Some countries depend on the hydro electric energy, where it necessitates the large amount of water storage. But, the enormous storage of water at a dam causes the shifting of poles which leads to the change in earth's rotation. To overcome these fluctuations in power generation and also meeting the required power demand, an efficient energy storage system is desirable. Therefore, ESSs are very much important while dealing with unpredictable environment of the renewable energy sources [5, 6].There exist the various types of energy storage systems based on several factors like nature, operating cycle duration, power density (PD) and energy d. As mentioned earlier, the SCs have gained much attention due to their phenomenal properties such as fast charge and discharge, long cycle life and high PD. This is due to the continuous breakthroughs associated with the SC materials and fabrication processes. On the other hand, the global SC market is expected to reach 720 million USD from 409 mill. -

In this paper we focus on understanding the rapid rise of the Chinese PV industry and its profound impact on the global PV industry. We investigate how it is possible that a nation that is still focusing on catching up in terms of industry, innovation and technology has been able to bring manufacturers from leading industrialized nations to their knees. This paper applies the framework of the Technological Innovation System (TIS), and also takes the context into account, in terms of the Chinese national innovation system (NIS) and the global PV TIS. It concludes that the rise of the Chinese PV TIS can be explained by the interaction of three context factors (the change in Chinese institutions, technology transfer, and the large European market) and specific PV TIS dynamics. The study empirically shows the importance of extending the national TIS studies by including the influences of context factors.••Solar PVTechnological innovation system (TIS)Context factorsChinaThe market for solar photovoltaics (PV) is growing rapidly. In the past decade, solar PV generation has expanded by 50% per year worldwide. In 2012, solar PV generation reached almost 100 TWh, which is sufficient to cover the annual power supply needs of over 30 million European households. In the same year, the world's cumulative total installed capacity exceeded 100 GW, up from only 1 GW in the year 2000,.This rapid market growth is mainly due to a massive reduction in production costs. For example, the inflation-adjusted prices of crystalline-silicon (c-Si) PV modules have fallen from 5.0 USD/watt in 2000 to around 0.6 USD/watt in June 2014,. This sharp drop in production costs has mainly been caused by process innovations in manufacturing technology, such as improvements in wire cutting technology. In addition, mass production has led to more efficient and cheaper solar cell production machinery. PV production lines have been optimized, for example by developments in intelligent and self-correcting control of process flow, and this has increased throughput volume. Furthermore, the efficiency of solar cells and modules has increased, resulting in higher returns on investments.Lower prices are good for consumers and for governments that use financial i. 2.1. TIS and its contextsTIS approach views innovation as a collective activity and analyzes how innovations are developed and deployed through the complex interactions among a multitude of different actors and organizations that are enabled and constrained by physical artifacts as well as by institutions that are regarded as 'the rules of the game'. The TIS perspective has often been applied to describe and analyze the emergence of radical innovations,,,. Many of the studies have focused on sustainable energy technologies in various countries around the world,,,, and many apply the scheme of analysis suggested by Bergek et al. This scheme suggests that analysts should create insight into the structure of the innovation system (the network of actors, institutions and physical infrastructure) and complement these insights by focusing on the key processes that take place in the innovation system. Hekkert et al. propose the following key processes: entrepreneurial experimentation, knowledge development, knowledge exchange, guidance of the search, market formation, resources mobilization, and creation of legitimacy (the seven system functions). The focus on key processes or functions complements the analysis of the structure of innovation systems since many different structural configurations may lead to a similar performance of the inn. 3.1. The beginningPV in China can be dated back to 1958, when the first piece of silicon single crystal was invented by the Chinese Academy of Sciences (CAS). Subsequently, the new Institute of Semiconductors, a subdivision of the CAS, started researching solar cells. In 1968, the first solar cells aimed at uses in space satellites were successfully developed and manufactured by an institute in Tianjin; they were installed on China's second satellite, Practice I, in 1971. In the 1970s, a few factories in the cities of Shanghai, Ningbo and Kaifeng produced solar cells for satellites; these factories were operated by the government. It is believed that at the time there was hardly any difference between the efficiency of the solar cells developed in China and of those developed in western countries. In 1973, PV started to be used on land as the energy source for the beacon light in Tianjin port. In subsequent years, some PV demonstration projects were set up for military communication systems, systems for the protection of petroleum pipelines, microwave relay stations, water pumps, and rural broadcasting stations,.3.2. 1985–1996: the pioneering eraIn. -
