The 2021 battery technology roadmap

Abstract

Sun, wind and tides have huge potential in providing us electricity in an environmental-friendly way. However, its intermittency and non-dispatchability are major reasons preventing full-scale adoption of renewable energy generation. Energy storage will enable this adoption by enabling a constant and high-quality electricity supply from these systems. But which storage technology should be considered is one of important issues. Nowadays, great effort has been focused on various kinds of batteries to store energy, lithium-related batteries, sodium-related batteries, zinc-related batteries, aluminum-related batteries and so on. Some cathodes can be used for these batteries, such as sulfur, oxygen, layered compounds. In addition, the construction of these batteries can be changed into flexible, flow or solid-state types. There are many challenges in electrode materials, electrolytes and construction of these batteries and research related to the battery systems for energy storage is extremely active. With the myriad of technologies and their associated technological challenges, we were motivated to assemble this 2020 battery technology roadmap.

Common ion effect enhanced Prussian blue analogues for aqueous ammonium ion storage

“…The result in TableS1† shows that the content of the Fe element is much larger than that of K (Fe: 4.56% and K: 0.02%), thus the K element can be negligible. Combined with the above analysis, it can be determined that the chemical formula of the synthetic FeHCF sample is FeFe(CN)6 •4H 2 O in this work.The morphological characteristics of the FeHCF powder can be clearly observed from its SEM and TEM images. As shown in Fig.…”

“…1,2 Among them, developing energy storage devices especially rechargeable batteries is a considerable strategy to provide stable energy. [3][4][5][6][7][8] Now they have become an indispensable part in our lives on account of their extensive utilization in many fields such as electronic portable devices. 9 In recent decades, as a representative of rechargeable batteries, Li + batteries with high energy density have satisfied a wide spectrum of needs.…”

Advanced Power Generation Using a Nitrogen Turbine Engine Instead of a Conventional Injection Steam Turbine Engine

“…What is more important to be concerned about than those challenges is the cost of production of batteries. However, there is a chance in the future that production costs would be lower as the method of battery production is improved [12][13][14][15][16][17][18][19][20][21][22][23].…”

Effect of Interfacial Intermetallic Compounds Morphology on Mechanical Properties of Laser Brazing of Aluminum to Steel

“…Recently, battery manufacturers have been attempting to develop battery technologies that increase energy density, to improve driving range and reduce the cost of electric vehicles [3]. The designs of commercial battery include cylindrical, prismatic and pouch cell types.…”
