Harvesting and storing energy is a key problem in some applications.Elastic energy storage technology has the advantages of wide-sources,simple structural principle,renewability,high effectiveness and environmental-friendliness.This paper elaborates the operational principles and technical properties and summarizes the appli-cability of elastic energy storage technology with spiral springs.Elastic energy storage using spiral spring can realize the balance between energy supply and demand in some applications.Continuous input-spontaneous out-put working style can provide simple energy sources for short-time energy supply,and provide strong moment impact and rapid start,or realize the energy conservation for reciprocating movement.Uniform output working style can realize energy output with uniform speed for timekeeping and load-driving.Random input working style can harvest and store random mechanical energy or convert small torque into a large moment to drive external loads.Finally,this paper proposes new researches and developments of elastic energy storage technology on new materials and structures,mechanical properties and structural dynamics analyses,design and control for new functions.

The world is rapidly adopting renewable energy alternatives at a remarkable rate to address the ever-increasing environmental crisis of CO_(2) emissions.Renewable energy system offers enormous potential to decarbonize the environment because they produce no greenhouse gases or other polluting emissions.However,the RES relies on natural resources for energy generation,such as sunlight,wind,water,geothermal,which are generally un-predictable and reliant on weather,season,and year.To account for these intermittencies,renewable energy can be stored using various techniques and then used in a consistent and controlled manner as needed.Several researchers from around the world have made substantial contributions over the last century to developing novel methods of energy storage that are efficient enough to meet increasing energy demand and technological break-throughs.This review attempts to provide a critical review of the advancements in the energy storage system from 1850-2022,including its evolution,classification,operating principles and comparison.

Effect of mechanical activation on enhancement of carbothermal reduction of nickel slag

引用

Journal of Iron and Steel Research(International) 2020年第11期27卷 1311-1321页

作者： Xiao-ming Li Hai-bo Yang Jin-bang Ruan Yi Li Zhen-yu Wen Xiang-dong Xing School of Metallurgical Engineering Xi'an University of Architecture and TechnologyXi'an 710055ShaanxiChina Shaanxi Engineering Research Center of Metallurgical Xi'an 710055ShaanxiChina

The effects of mechanical activation on particle size distribution,crystalline phase,morphology,and mechanical energy storage of nickel slag were studied.Then,the direct reduction experiments of mechanically activated nickel slag mixed with reducing agent graphite powder were performed under conditions of 873-1273 K and reduction for 30-70 min.The results show that after 12 h of activation,90%of the nickel slag has a particle diameter less than 1.05 pm,and the total energy storage is 1790.4 kJ mol^(-1).With the extension of the mechanical activation duration,the intensity of the dift'raction peaks of the main crystalline phases Fe_(2)SiO_(4) and Mg2SiO4 in the nickel slag decreases.mechanical activation is also an effective means to enhance the reduction of nickel slag.With the extension of the activation time,the reduction effect of the nickel slag and metallization degree increase.After 12 h of mechanical activation,the nickel slag was reduced at 1273 K for 70 min,and the metallization degree of the reduced product could reach 83.12%.
