Electrolyte design holds the greatest opportunity for the development of batteries that are capable of sub-zero temperature operation.To get the most energy storage out of the battery at low temperatures,improvements in electrolyte chemistry need to be coupled with optimized electrode materials and tailored electrolyte/electrode interphases.Herein,this review critically outlines electrolytes’limiting factors,including reduced ionic conductivity,large de-solvation energy,sluggish charge transfer,and slow Li-ion transportation across the electrolyte/electrode interphases,which affect the low-temperature performance of Li-metal batteries.Detailed theoretical derivations that explain the explicit influence of temperature on battery performance are presented to deepen understanding.Emerging improvement strategies from the aspects of electrolyte design and electrolyte/electrode interphase engineering are summarized and rigorously compared.Perspectives on future research are proposed to guide the ongoing exploration for better low-temperature Li-metal batteries.

As an advanced energy storage system,lithium-ion batteries play an essential role in modern technologies.Despite their ubiquitous success,there is a great demand for continuous improvements of the battery performance,including higher energy density,lower safety risk,longer cycling life,and lower cost.Such performance improvement requires the design and development of novel electrode and electrolyte materials that exhibit desirable properties and satisfy strict requirements.Atomistic modeling can provide a unique perspective to fundamentally understand and rationally design battery materials.In this paper,we review a few recent successful examples of computation-driven discovery and design in electrode and electrolyte materials.Particularly,we highlight how atomistic modeling can reveal the underlying mechanisms,predict the important properties,and guide the design and engineering of electrode and electrolyte materials.We have a conclusion with a discussion of the unique capability of atomistic modeling in battery material development and provide a perspective on future challenges and directions for computation-driven battery material developments.

Combining the unique advantages of aqueous electrolytes and metallic Zn anode, rechargeable aqueous Zn-ion batteries(ZIBs) are of great promise for large-scale energy storage applications due to their inherent high safety, low cost, and environmental friendliness. As the essential component of ZIBs, Zn metal anode suffers from severe dendrite formation and inevitable side reactions(e.g. corrosion and hydrogen evolution)in aqueous electrolytes, which leads to low Coulombic efficiency and inferior cycling stability, impeding their large-scale applications. To be compatible with satisfactory aqueous ZIBs, Zn anode has been modified from various perspectives and focus areas. Herein, based on their intrinsic characteristics, we review the related improvement strategies for Zn anode, including interphase, substrate, and bulk design, so as to achieve an in-depth understanding of Zn anode optimization. Furthermore, the timely summary of characterization methods for Zn anodes are also performed for the first time, from both thermodynamic and kinetics perspectives, which is particularly helpful for beginners to understand the complicated characterizations and employ suitable methods. Finally, certain noteworthy points are put forward for subsequent investigation of aqueous ZIBs. It is expected that this review will enlighten researchers to explore more efficient optimization strategies for Zn anode in aqueous electrolytes.

Co-Optimization of Behind-the-Meter and Front-of-Meter Value Streams in Community batteries

引用

JOURNAL OF MODERN POWER SYSTEMS AND CLEAN ENERGY 2024年第2期12卷 334-345页

作者： Domenech, Carmen Bas De Corato, Antonella Maria Mancarella, Pierluigi Univ Melbourne Parkville Vic 2010 Australia Univ Manchester Dept Elect & Elect Engn Manchester England

Community batteries (CBs) are emerging to support and even enable energy communities and generally help consumers, especially space-constrained ones, to access potential techno-economic benefits from storage and support local grid decarbonization. However, the economic viability of CB projects is often uncertain. In this regard, typical feasibility studies assess CB value for behind-the-meter (BTM) operation or whole-sale market participation, i.e., front-of-meter (FOM). This work proposes a novel techno-economic operational framework that allows systematic assessment of the different options and introduces a two-meter architecture that co-optimizes both BTM and FOM benefits. A real CB project application in Australia is used to demonstrate the significant two-meter co-optimization opportunities that could enhance the business case of CB and energy communities by multi-service provision and value stacking.

Flexible and free-standing electrospun nanofibres have been used as electrode materials in electrochemical energy storage systems due to their versatile properties,such as mechanical stability,superb electrical conductivity,and high functionality.In energy storage systems such as metal-ion,metal-air,and metal-sulphur batteries,electrospun nanofibres are vital for constructing flexible electrodes and substantially enhancing their electrochemical properties.The need for flexible batteries has increased with increasing demand for new products such as wearable and flexible devices,including smartwatches and flexible displays.Conventional batteries have several semirigid to rigid components that limit their expansion in the flexible device market.The creation of flexible and wearable batteries with greater mechanical flexibility,higher energy,and substantial power density is critical in meeting the demand for these new electronic items.The implementation of carbon and carbon-derived composites into flexible electrodes is required to realize this goal.It is essential to understand recent advances and the comprehensive foundation behind the synthesis and assembly of various flexible electrospun nanofibres.The design of nanofibres,including those comprising carbon,N-doped carbon,hierarchical,porous carbon,and metal/metal oxide carbon composites,will be explored.We will highlight the merits of electrospun carbon flexible electrodes by describing porosity,surface area,binder-free and free-standing electrode construction,cycling stability,and performance rate.Significant scientific progress has been achieved and logistical challenges have been met in promoting secondary battery usage;therefore,this review of flexible electrode materials will advance this easily used and sought-after technology.The challenges and prospects involved in the timely development of carbon nanofibre composite flexible electrodes and batteries will be addressed.

Recently,Li-CO_(2) battery has gradually become a research hotspot due to its high discharge capacity,energy density and environmental benefits.However,it has been an important problem for researchers because of its slow decomposition kinetics and difficult to generalize to practical application.Herein,we prepared copper polyphthalocyanine-carbon nanotubes composites(CuPPc-CNTs)by solvothermal in-situ polymerization of copper phthalocyanine on the surface of carbon nanotubes as cathode for reversible Li-CO_(2) batteries,which exhibits a high discharge capacity of 18,652.7 mAh·g^(-1) at current density of 100 mA·g^(-1),1.64 V polarization at 1,000 mA·g^(-1),and a stable cycles number of 160 is close to 1,630 h of charge-discharge process at 200 mA·g^(-1).Copper polyphthalocyanine has highly efficient copper single-atom catalytic sites with excellent CO_(2) adsorption and activation,while carbon nanotubes provide a conductive network.The synergistic effect of the two compounds enables it to have excellent catalytic activity.The density functional theory(DFT)calculation proved that the addition of copper polyphthalocyanine significantly improved the CO_(2) adsorption and activation process.This study provides an opportunity for the research of covalent organic polymers(COPs)single-atom catalyst in Li-CO_(2) battery field.

The cathode of lithium-oxygen(Li-O_(2))batteries should have large space for high Li_(2)O_(2) uptake and superior electrocatalytic activity to oxygen evolution/reduction for long lifespan.Herein,a high-performance MnO_(x)/hCNC cathode was constructed by the defect-induced deposition of manganese oxide(MnOx)nanoparticles on hierarchical carbon nanocages(hCNC).The corresponding Li-O2 battery(MnOx/hCNC@Li-O_(2))exhibited excellent electrocatalytic activity with the low overpotential of 0.73-0.99 V in the current density range of 0.1-1.0 A·g^(-1).The full discharge capacity and cycling life of MnO_(x)/hCNC@Li-O_(2) were increased by~86.7%and~91%,respectively,compared with the hCNC@Li-O_(2) counterpart.The superior performance of MnO_(x)/hCNC cathode was ascribed to(i)the highly dispersed MnO_(x) nanoparticles for boosting the reversibility of oxygen evolution/reduction reactions,(ii)the interconnecting pore structure for increasing Li_(2)O_(2) accommodation and facilitating charge/mass transfer,and(iii)the concealed surface defects of hCNC for suppressing side reactions.This study demonstrated an effective strategy to improve the performance of Li-O_(2) batteries by constructing cathodes with highly dispersed catalytic sites and hierarchical porous structure.

The most important components of electrical vehicles are the battery and the related cooling system.These subsystems play a major role in determining the overall electric vehicle performances.In this study,a novel cooling system with fluid in the battery cell is proposed,by which the energy storage system can be optimized through control of the temperature of the batteries.A sensitivity analysis is conducted considering the maximum temperature,the heat rate,the coolant temperature,and the geometry of the cavities.The numerical simulations show that the parameters for the trapezoidal compartment have an impact on the thermal performance of battery.An optimal geometry is proposed accordingly.It is concluded that for high values of Reynolds number for which the flow becomes turbulent,a decrease in the battery temperature can be obtained thereby avoiding thermal stresses.
