As an effective energy storage technology, rechargeable batteries have long been considered as a promising solution for grid integration of intermittent renewables(such as solar and wind energy). However,their wide application is still limited by safety issue and high cost. Herein, a new battery chemistry is proposed to satisfy the requirements of grid energy storage. We report a simple Cu-Mn battery, which is composed of two separated current collectors in an H2SO4-CuSO4-MnSO4 electrolyte without using any membrane. The Cu-Mn battery shows an energy density of 40.8 Wh L-1, a super-long life of 10,000 cycles(without obvious capacity decay) and negligible self-discharge. And the capital cost of US$ 11.9 kWh-1 based on electrolyte is lower than any previous batteries. More importantly, the battery can still work smoothly during thermal abuse test and drill-through test, showing high safe nature. Furthermore, a combination system integrating the Cu-Mn battery and hydrogen evolution is also proposed, which is able to avoid the generation of explosive H2/O2 mixture, and presents an efficient approach for grid energy storage and conversion.

The commercialization of electrolytic MnO_(2)-Zn batteries is highly applauded owing to the advantages of cost-effectiveness,high safety,high energy density,and durable working performance.However,due to the low reversibility of the cathode MnO_(2)/Mn^(2+)chemistry at high areal capacities and the severe Zn anode corrosion,the practical application of MnO_(2)-Zn batteries is hampered by inadequate lifespan.Leveraging the full advantage of an iodine redox mediator,here we design a highly rechargeable electrolytic MnO_(2)-Zn battery with a high areal capacity.The MnO_(2)-Zn battery coupled with an iodine mediator in a mild electrolyte shows a high discharge voltage of 1.85 V and a robust areal capacity of 10 mAh cm^(-2)under a substantial discharge current density of 160 mA cm^(-2).The MnO_(2)/I_(2)-Zn battery with an areal capacity of 10 mAh cm^(-2)exhibits prolonged stability of over 950 cycles under a high-capacity retention of~94%.The scaled-up MnO_(2)/I_(2)-Zn battery reveals a stable cycle life under a cell capacity of~600 mAh.Moreover,our constructed MnO_(2)/I_(2)-Zn battery demonstrates a practical energy density of~37 Wh kg^(-1)and a competitive energy cost ofenergy density,enlightens a new arena of large-scale energy storage devices.

The battery management system(BMS)is the main safeguard of a battery system for electric propulsion and machine electrifcation.It is tasked to ensure reliable and safe operation of battery cells connected to provide high currents at high voltage levels.In addition to efectively monitoring all the electrical parameters of a battery pack system,such as the voltage,current,and temperature,the BMS is also used to improve the battery performance with proper safety measures within the system.With growing acceptance of lithium-ion batteries,major industry sectors such as the automotive,renewable energy,manufacturing,construction,and even some in the mining industry have brought forward the mass transition from fossil fuel dependency to electric powered machinery and redefned the world of energy storage.Hence,the functional safety considerations,which are those relating to automatic protection,in battery management for battery pack technologies are particularly important to ensure that the overall electrical system,regardless of whether it is for electric transportation or stationary energy storage,is in accordance with high standards of safety,reliability,and quality.If the system or product fails to meet functional and other safety requirements on account of faulty design or a sequence of failure events,then the environment,people,and property could be endangered.This paper analyzed the details of BMS for electric transportation and large-scale energy storage systems,particularly in areas concerned with hazardous environment.The analysis covers the aspect of functional safety that applies to BMS and is in accordance with the relevant industrial standards.A comprehensive evaluation of the components,architecture,risk reduction techniques,and failure mode analysis applicable to BMS operation was also presented.The article further provided recommendations on safety design and performance optimization in relation to the overall BMS integration.

High temperature Superconducting Magnetic energy storage(SMES) systems can exchange energy with substantial renewable power grids in a small period of time with very high efficiency. Because of this distinctive feature, they store the abundant wind power when the power network is congested and release the energy back to the system when there is no congestion. However, considering the cost and lifespan of SMES systems, there is an urgent demand to conduct a cost-benefit analysis to justify its role in smart grid development. This study explores the application and performs economic analysis of a 5 MJ SMES in a practical renewable power system in China based on the PSCAD/EMTDC software. An optimal location of SMES in Zhangbei wind farm is presented using real power transmission parameters. The stabilities of the renewable power grid with and without SMES are discussed. In addition, a financial feasibility study is conducted by comparing the cost and the savings from wind power curtailment of deploying SMES and battery. The economic analysis tries to find the balance between SMES investment cost and wind farm operation cost by using real data over a calendar year. The technical analysis can help guide the optimal allocation of SMES for compensating power system instability with substantial wind power. Further, the economic analysis provides a useful indication of its practical application feasibility to fight the balance between cost and benefit.

Rechargeable aluminum batteries(RABs)have attracted great interest as one of the most promising candidates for large-scale energy storage because of their high volumetric capacity,low cost,high safety and the abundance of aluminum.However,compared with the aluminum anodes,the cathode materials face more problems including low specific capacity,relatively sluggish kinetics in most host structures and/or limited cycle lifespan,which pose the major challenge for RABs in further practical applications.During the past years,intensive efforts have been devoted to developing new cathode materials and/or designing engineered nanostructures to greatly improve RABs’electrochemical performances.In addition to nanotechnologybased electrode structure designs,the intrinsic chemical structures and charge storage mechanisms of cathode materials play an equally crucial role,if not more,in revolutionizing the battery performances.This review,here,focuses on current understandings into the charge storage mechanisms of cathode materials in RABs from a chemical reaction point of view.First,the fundamental chemistry,charge storage mechanisms and design principles of RAB cathode materials are highlighted.Based on different ion charge carriers,the current cathode materials are classified into four groups,including Al^(3+)-hosting,Al Cl_(4)^(-)-hosting,Al Cl_(2)^(+)/Al Cl_(2)^(+)-hosting,and Cl^(-)-hosting cathode materials.Next,the respective typical electrode structures,optimization strategies,electrochemical performances and charge storage mechanisms are discussed in detail to establish their chemistry-structure-property relationships.This review on current understandings of the cathode charge storage mechanisms will lay the ground and hopefully set new directions into the rational design of high-performance cathode materials in RABs,and open up new opportunities for designing new electrolyte systems with respect to the targeted cathode systems.

Electrolytic MnO_(2)/Zn batteries have attracted extensive attention for use in large-scale energy storage applications due to their low cost,high output voltage,safety,and environmental friendliness.However,the poor electrical conductivity of MnO_(2)limits its deposition and dissolution at large capacities,which leads to sluggish reaction kinetics and drastic capacity decay.Here,we report a theory-guided design principle for an electrolytic MnO_(2)/Zn battery co-regulated with transition metal ions that has improved electrochemical performance in terms of deposition and stripping chemistries.We start with first-principles calculations to predict the electrolytic effects of regulating transition metal ions in the deposition/stripping chemistry of the MnO_(2)cathode.The results indicate that with the simultaneous incorporation of strongly electronegative Co and Ni,the MnO_(2)cathode tends to possess more active electron states,faster charge-transfer kinetics,and better electrical conductivity than either MnO_(2)regulated with Co or Ni on their own,or pristine MnO_(2);hence,this co-regulation is beneficial for the cathode solid/liquid MnO_(2)/Mn2t reactions.We then fabricate and demonstrate a novel Co2t and Ni2t coregulated MnO_(2)/Zn(Co-Ni-MnO_(2)/Zn)battery that yields significantly better electrochemical performance,finding that the synergistic regulation of Co and Ni on MnO_(2)can significantly increase its intrinsic conductivity and achieve high rates and Coulombic efficiencies at large capacities.The aqueous Co-Ni-MnO_(2)/Zn battery exhibits a high rate(10C,100 mA cm^(-2)),high Coulombic efficiency(91.89%),and excellent cycling stability(600 cycles without decay)at a large areal capacity of 10 mAh cm^(-2).Our proposed strategy of co-regulation with transition metal ions offers a versatile approach for improving the electrochemical performance of aqueous electrolytic MnO_(2)/Zn batteries in large-scale energy storage applications.
