However, their matching cathodes are still limited by slow ion transport dynamics and oxidation. Here, we report a series of hydrated films that comprise small sheets of reduced graphene oxide (SSs−rGO, <100 nm in average lateral size) and feature short interlayered pathways (∼100 nm) for rapid ion transport and high oxidation resistance. As the first ultrahigh-rate cathode with areal capacitance (Ca) satisfying an industrial requirement (>0.6 F cm−2), the SSs−rGO electrode (5.0 mg cm−2) delivers a Ca of 0.61 F cm−2 and a gravimetric capacitance of 123 F g−1 at an ultrahigh-rate of 3,000 mV s−1. Combining with a Ti3C2Tx anode, the cathode enables a 1.8 V ultrafast aqueous supercapacitor that delivers energy densities of 0.14 and 0.09 mWh cm−2 for discharges in 1.79 and 0.97 s (∼2,000 and 3,700 C rate), respectively. These values double (at 2,000 C) and almost ten-fold (at 3,700 C) those of the ever-reported supercapacitors operating at the corresponding rates. The present strategy paves a road to ultrafast (>1,000 C) and high-energy-density supercapacitors, by which energy charge/discharge can finish within 3.6 s.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"200 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional ethyl carbonate (EC)-based electrolytes with solvent-dominated solvation configuration suffer from sluggish reaction kinetics, severe interfacial side reactions and high Li+ desolvation energy under low temperature. Herein, an EC-free and weakly solvated electrolyte consisting of LiDFOB and mixed solvents including dimethyl sulfite (DMS), ethyl trifluoroacetate (ETFA) and fluoroethylene carbonate (FEC) was designed to facilitate the reaction kinetics and stabilize the interfaces of LT-LMBs, where a fluoride-rich solvation structure including FEC, ETFA and DFOB- is formed in the designed electrolyte. Such solvation configuration could significantly facilitate the desolvation process and induce the homogeneous Li deposition by forming high ionic conductive and inorganics-rich protective film on the electrode surfaces. With such electrolyte, the Li||NCM811 cell retains a high capacity retention of 81.7% after 1000 cycles, which is far superior to the 31.3% for EC-based electrolyte. Even at -40°C, the cell exhibits a capacity of 125.7 mAh g-1 with almost no capacity attenuation after 200 cycles. This work confirms the necessity of fluoride-dominated solvation structure in decreasing the desolvation energy and accelerating the ionic transfer, contributing a promising solution to the development of low-temperature LMBs.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"20 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the fast capacity decay impedes their commercial viability, primarily due to the lack of excessive Li from the anode to compensate for the irreversible lithium loss. Thus, the Li-rich NCM cathode is a feasible way to solve the issue. In this work, to search for the ideal Li1+xTMO2 cathode for anode-free Li metal batteries, we selected the two types of commonly used layered cathode materials (LiTMO2: NCM622 and NCM811) to enrich Li converting into Li2TMO2 by both chemical lithiation (C-Li) and electrochemical lithiation (E-Li) methods. Our findings show that the Li-rich NCM622 lithiated by the E-Li method is an ideal choice among our candidates, which has a high lithiation degree that almost covers the entire reversible transition range from Li1 to Li2 without additional by-products and a negative impact on kinetic performance. Based on the above results, we further demonstrated that the Li1.33NCM622|Cu pouch cell presents a longer cycle life of more than 200 times with a high capacity retention of 74%.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"37 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resultant Zn2+(ZrT)(DMF)1 solvation structure features a large solvation sheath and a small ion-to-electrode distance, thus reducing the energy required for reorganizing the solvation sheath to accept electron. As a result, the MOPs-modulated colloidal electrolyte enables Zn anode with supreme stability for over 1200 h at 8 mA cm−2 and 270 h at 12 mA cm−2, along with high coulombic efficiency (∼99.8% over 1000 cycles), notably exceeding the performance of conventional aqueous and nonaqueous electrolytes.

Designing of structural electrodes has proven effective in enhancing battery deformability. However, this often compromises electrode areal loading, resulting in lower areal capacities. Herein, we design multiscale biomimetic structural electrodes fabricated via an in-situ directional freezing-assisted 3D printing approach. This new approach effectively incorporates microscopic directionally porous structures and macroscopic serpentine structures, achieving the designed compatibility with ultrahigh deformation and ultrahigh areal capacities simultaneously. The thus-made electrodes allow for exceptional deformability, including 300% stretching, 180° twisting, and 360° bending, while maintaining a high areal loading of up to ∼65%. The half-cells with directional micro-channel electrodes demonstrate superior specific capacities, cycling stability, and rate capability, when compared to the cells with nondirectional electrodes. The assembled Li-ion full-cell can readily power LEDs in various deformable states, and a structure-integrated wearable watch device is designed in a bent watchband configuration. Our new strategy offers a rational design approach for highly deformable and customized electrodes, advancing the development of deformable batteries for wearable devices.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"9 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a material design inspired by the cross-property connection phenomena, which bridges the seemingly unrelated material properties through similar or relevant determining microscopic factors, is reported to achieve substantially improved high-temperature capacitive performance in dielectric polymers. A high consistency is unveiled between the high-temperature electrical properties and thermal expansion of dielectric polymers, based on which a surface-gradient crosslinking structure is designed to inhibit the thermal distortion. It is confirmed by both experimental results and computational simulations that the restricted thermal expansion gives rise to reduced free volume as well as suppressed β-relaxation, which account for the marked improvements in high-temperature capacitive performances. At the optimal composition, the resultant polymer exhibits an ultrahigh discharged energy density up to 4.9 J/cm3 at 200 °C with a charge-discharge efficiency of 90%, which is superior to all the existing polymer films based on the surface modification.

These characteristics of HEMs significantly enhance the performance of rechargeable batteries and supercapacitors by improving electronic conductivity and ionic transport of the relevant battery composition as well as expanding the operational battery temperature. This paper timely summarizes the function principles of the four primary enhancement mechanisms of HEMs and resultant recent applications in energy storage and conversion technologies, including cathodes, anodes, and electrolytes. Considerable emphasis is focused on the functional orientation screen and the synthesis of HEM elements/structures towards stability and power capability of the electrode reactions. Finally, the current challenge, the possible solving strategies and the future research trend for HEMs are outlined.
