Hybrid energy storage systems (HESS) are an exciting emerging technology. Dubal et al. [ 172] emphasize the position of supercapacitors and pseudocapacitors as in a middle ground between batteries and traditional capacitors within Ragone plots. The mechanisms for storage in these systems have been optimized separately.
Electric vehicles (EVs) of the modern era are almost on the verge of tipping scale against internal combustion engines (ICE). ICE vehicles are favorable since petrol has a much higher energy density and requires less space for storage. However, the ICE emits carbon dioxide which pollutes the environment and causes global warming. Hence, …

The heterostructures were advantageous for penetration of electrolyte ions into the MXene layers and exhibited excellent electrochemical cycling stability with above 99% retention over 10 000 cycles. The high capacitance and excellent cycling stability demonstrate the great promise of this simple and scalable approach for developing high-performance …
Abstract. Energy consumption in the world has increased significantly over the past 20 years. In 2008, worldwide energy consumption was reported as 142,270 TWh [1], in contrast to 54,282 TWh in 1973; [2] this represents an increase of 262%. The surge in demand could be attributed to the growth of population and industrialization over …
