＜正＞The open voltage of batteries showed different status after MH-Ni batteries were stored for a period of time. Some batteries with 0 V, 0.9-1.1V, above 1.1 V were chosen to study their corresponding internal resistances, open voltages and capacities, etc. On the basis of battery reaction principle, battery samples were analyzed, and factors caused different storage performance were found out. Therefore, some references on improvement of battery storage performance were provided

＜正＞ The open voltage of batteries shows different status after MH-Ni batteries are stored for a period of time. Some batteries with 0, 0.9 - 1.1V and above 1.1 V were chosen to study their corresponding internal resistances, open voltages and the reduction of capacities, etc. On the basis of battery reaction principle, battery samples were analyzed, and factors causing different storage performance were found out. Therefore, some references on the improvement of battery storage performance were provided.

Hydrogen has emerged as a promising alternative to meet the growing demand for sustainable and renewable energy sources. Underground hydrogen storage(UHS) in depleted gas reservoirs holds significant potential for large-scale energy storage and the seamless integration of intermittent renewable energy sources, due to its capacity to address challenges associated with the intermittent nature of renewable energy sources, ensuring a steady and reliable energy supply. Leveraging the existing infrastructure and well-characterized geological formations, depleted gas reservoirs offer an attractive option for large-scale hydrogen storage implementation. However, significant knowledge gaps regarding storage performance hinder the commercialization of UHS operation. Hydrogen deliverability, hydrogen trapping, and the equation of state are key areas with limited understanding. This literature review critically analyzes and synthesizes existing research on hydrogen storage performance during underground storage in depleted gas reservoirs; it then provides a high-level risk assessment and an overview of the techno-economics of UHS. The significance of this review lies in its consolidation of current knowledge,highlighting unresolved issues and proposing areas for future research. Addressing these gaps will advance hydrogen-based energy systems and support the transition to a sustainable energy *** efficient and safe deployment of UHS in depleted gas reservoirs will assist in unlocking hydrogen's full potential as a clean and renewable energy carrier. In addition, this review aids policymakers and the scientific community in making informed decisions regarding hydrogen storage technologies.

Rare Metals 2009年第4期28卷 322-327页

作者： LIU Yunjian LI Xinhai GUO Huajun WANG Zhixing HU Qiyang PENG Wenjie YANG Yong School of Metallurgical Science and Engineering Central South University Changsha 410083 China

Spinel LiMn204 was synthesized by a solid-state method. A 204468-size battery was fabricated and stored at 55℃. The structure and morphology of the LiMn204 cathode were analyzed by X-ray diffraction （XRD） and scanning electron microscopy （SEM） technique. Energy dispersive spectroscopy （EDS） was used to analyze the surface component of the carbon anode. The discharge capacities of LiMn204 stored for 0, 24, 48, and 96 h are 106, 98, 96, and 92 mAh·g^-1, respectively. The cyclic performance is improved after storage. The capacity retentions of LiMn204 stored for 0, 24, 48, and 96 h are 83.8%, 85.8%, 86.9%, and 88.6% after 180 cycles. The intensity of all the LiMn204 diffraction peaks is weakened. Mn is detected from the carbon electrode when the battery is stored for 96 h. Cyclic voltammograms and electrochemical impedance spectroscopy （EIS） were used to examine the surface state of the electrode after storage. The results show that the resistance and polarization of LiMn2O4/electrolyte is increased after storage, which is responsible for the fading of capacity.
