| 1 | Carbon-coated manganese dioxide nanoparticles and their enhanced electrochemical properties for zinc-ion battery applications显示文摘In this study, we report the cost-effective and simple synthesis of carbon-coated α-MnO_2nanoparticles(α-MnO_2@C) for use as cathodes of aqueous zinc-ion batteries(ZIBs) for the first time. α-MnO_2@C was prepared via a gel formation, using maleic acid(C_4H_4O_4) as the carbon source, followed by annealing at low temperature of 270 °C. A uniform carbon network among the α-MnO_2 nanoparticles was observed by transmission electron microscopy. When tested in a zinc cell, the α-MnO_2@C exhibited a high initial discharge capacity of 272 m Ah/g under 66 m A/g current density compared to 213 m Ah/g, at the same current density, displayed by the pristine sample. Further, α-MnO_2@C demonstrated superior cycleability compared to the pristine samples. This study may pave the way for the utilizing carbon-coated MnO_2 electrodes for aqueous ZIB applications and thereby contribute to realizing high performance eco-friendly batteries. | Saiful Islam Muhammad Hilmy Alfaruqi Jinju Song Sungjin Kim Duong Tung Pham Jeonggeun Jo Seokhun Kim Vinod Mathew Joseph Paul Baboo Zhiliang Xiu Jaekook Kim | 2017 | Journal of Energy Chemistry2017，26，4： | 6 |
| 2 | Metal organic framework-combustion: A one-pot strategy to NiO nanoparticles with excellent anode properties for lithium ion batteries显示文摘NiO nanoparticles with average particles size of 30 nm are synthesized using a one-pot metal–organic framework-combustion(MOF-C) technique, for use as an anode material in rechargeable lithium ion batteries(LIBs). The structural and electronic properties of these nanoparticles are studied using various techniques, including powder X-ray diffraction(PXRD), transmission electron microscopy(TEM), scanning electron microscopy(SEM), X-ray photoelectron spectroscopy(XPS), and N_2 adsorption/desorption studies. The as-synthesized NiO nanoparticles sustained reversible stable capacities of 748 and 410 mAh/g at applied current densities of 500 and 1000 m A/g, respectively, after 100 cycles. Furthermore, the anode displays a notable rate capability, achieving a stable capacity of ~200 mAh/g at a high current density of10 A/g. These results indicate that the size of the NiO nanoparticles and their high surface area influence their electrochemical properties. Specifically, this combustion strategy is clearly favorable for improving the cyclability and rate capability of various metal oxides in rechargeable battery electrodes. | Vaiyapuri Soundharrajan Balaji Sambandam Jinju Song Sungjin Kim Jeonggeun Jo Pham Tung Duong Seokhun Kim Vinod Mathew Jaekook Kim | 2018 | Journal of Energy Chemistry2018，27，1： | 4 |
| 3 | Phase-pure Na3V2(PO4)2F3 embedded in carbon matrix through a facile polyol synthesis as a potential cathode for high performance sodium-ion batteries显示文摘In this study,a pseudo-layered Na super-ionic conductor of Na3V2(PO4)2F3 (NVPF)/C cathode for sodium-ion batteries is prepared successfully using a facile polyol refluxing process without any impurity phases.The X-ray diffraction and Rietveld refinement results confirm that NVPF possesses tetragonal NASICON-type lattice with a space group of P42/mnm.In this preparative method,polyol is utilized as a solvent as well as a carbon source.The presence of nanosized NVPF particles in the carbon network is confirmed by field-emission scanning electron microscopy (FE-SEM) and high-resolution transmission electron microscopy (HR-TEM).The existence of carbon is analyzed by Raman scattering and elemental analysis.When applied as a Na-storage material in a potential window of 2.0-4.3 V,the electrode exhibits two flat voltage plateaus at 3.7 and 4.2 V with an electrochemically active V^3+/V^4+ redox couple.In addition,Na3V2(PO4)2F3/C composite achieved a retention capacity of ~ 88% even after 1,500 cycles at 15 C.Moreover,at high current densities of 30 and 50 C,Na3V2(PO4)2F3/C cathode retains the specific discharge capacities of 108.4 and 105.9 mAh·g-1,respectively,revealing the structural stability of the material prepared through a facile polyol refluxing method. | Sohyun Park Jinju Song Seyeon Kim Balaji Sambandam Vinod Mathew Sungjin Kim Jeonggeun Jo Seokhun Kim Jaekook Kim | 2019 | Nano Research2019，12，4： | 4 |

| 12 | A Critical Comparison of Mildly Acidic versus Alkaline Zinc Batteries显示文摘Aqueous rechargeable batteries are cost-effective,easy to fabricate,and safe,deliver high energy output,and employ stable water-based electrolytes compared to organicbased lithium-ion batteries(LIBs).Aqueous Zn electrochemistry,specifically,has attracted researchers since the 1830s.Metallic Zn is a nearly ideal anode owing to its low cost(ca.2 USD kg^(−1)),existing supply chain,environmental benignity,relative safety,and high stability in water[−0.76 V vs standard hydrogen electrode(SHE)],as compared to Li.^(1−3) The high theoretical capacity(2e−@820 mAh g^(−1))and low polarizability(6×10^(−8)Ωm)further motivate Zn-based battery development,especially for stationary storage.2,4 Alkaline Zn batteries(AZBs)and neutral/mildly acidic Znion batteries(MZIBs)are proposed as rivals to the established Pb-acid and LIBs owing to their competitive theoretical energy densities(∼200−400 Wh L^(−1)).The efficiency of these inexpensive and safe battery technologies is dependent on the cathode type,Zn anode formulation,separator materials,and the electrolyte type(liquid,gel,solid state)and pH.While AZBs and MZIBs have commonalities,including Zn dendrite formation at high capacity utilization and inherent low voltage(Zn battery<3 V | Vinod Mathew Noah B.Schorr Balaji Sambandam Timothy N.Lambert Jaekook Kim | 2023 | Accounts of Materials Research2023，4，4： | 0 |
| 13 | Construction of a High‑Performance Composite Solid Electrolyte Through In‑Situ Polymerization within a Self‑Supported Porous Garnet Framework显示文摘Composite solid electrolytes(CSEs)have emerged as promising candidates for safe and high-energy–density solid-state lithium metal batteries(SSLMBs).However,concurrently achieving exceptional ionic conductivity and interface compatibility between the electrolyte and electrode presents a significant challenge in the development of high-performance CSEs for SSLMBs.To overcome these challenges,we present a method involving the in-situ polymerization of a monomer within a self-supported porous Li_(6.4)La_(3)Zr_(1.4)Ta_(0.6)O_(12)(LLZT)to produce the CSE.The synergy of the continuous conductive LLZT network,well-organized polymer,and their interface can enhance the ionic conductivity of the CSE at room temperature.Furthermore,the in-situ polymerization process can also con-struct the integration and compatibility of the solid electrolyte–solid electrode interface.The synthesized CSE exhibited a high ionic conductivity of 1.117 mS cm^(-1),a significant lithium transference number of 0.627,and exhibited electrochemical stability up to 5.06 V vs.Li/Li+at 30℃.Moreover,the Li|CSE|LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2) cell delivered a discharge capacity of 105.1 mAh g^(-1) after 400 cycles at 0.5 C and 30℃,corresponding to a capacity retention of 61%.This methodology could be extended to a variety of ceramic,polymer electrolytes,or battery systems,thereby offering a viable strategy to improve the electrochemical properties of CSEs for high-energy–density SSLMBs. | An‑Giang Nguyen Min‑Ho Lee Jaekook Kim Chan‑Jin Park | 2024 | Nano-Micro Letters2024，16，5： | 0 |
| 14 | In-situ electrochemical functionalization of carbon materials for high-performance Li–O2 batteries显示文摘The development of effective synthetic routes is important to manifest proper nature of specific materials.In-situ electrochemical functionalization possesses great advantages over conventional routes,especially facile way and leading to reaching elaborate sites of functional group.Here,we demonstrate the preparation of functionalized carbons by in-situ electrochemical reduction in an argon atmosphere for application in low-cost,environmentally benign,and high-performance oxygen-electrodes for non-aqueous Li-O2 batteries.A Li-O2 battery with functionalized carbon shows a high discharge capacity(100 times that of pristine carbon),high power and cycling stability.The outstanding performance is attributed to the high O2 affinity of the functionalized carbon surface that facilitates the formation of soluble and diffusible superoxide intermediates by the reduction of the remaining O2 competing with surface growth for Li2O2 formation. | Jungwon Kang Jin Min Kim Do Youb Kim Jungdon Suk Jaekook Kim Dong Wook Kim Yongku Kang | 2020 | Journal of Energy Chemistry2020，29，9： | 0 |
