The composite of nitrogen-doped carbon (N-C) blend with lithium aluminum germanium phosphate (LAGP) was studied as cathode material in a solid-state lithium-oxygen cell. Composite electrodes exhibit high electrochemical activity toward oxygen reduction. Compared to the cell capacity of N-C blend cathode, N-C/LAGP composite cathode exhibits six times higher discharge cell capacity. A significant enhancement in cell capacity is attributed to higher electrocatalytic activity and fast lithium ion conduction ability of LAGP in the cathode.

    • "In general, lithium-air batteries can be divided into four types [3] in terms of electrolytes, including aqueous, non-aqueous, mixed aqueous/non-aqueous (hybrid), and solid-state. In aqueous [4] [5] [6] [7] [8] [9] [10], hybrid [11] [12] [13] [14] [15] [16], and solid-state [17] [18] [19] [20] [21] [22] [23] [24] lithium-air batteries , a solid-state layer is generally used to transport Li + ions. The internal resistance associated with this solid plate can be a main factor that limits the performance of these types of battery. "

    ABSTRACT: h i g h l i g h t s The theoretical capacity of non-aqueous lithium-air batteries is predicted. Key battery design parameters are defined and considered. The theoretical battery capacity is about 10% of the lithium capacity. The battery mass and volume changes after discharge are also studied. a b s t r a c t In attempt to realistically assess the high-capacity feature of emerging lithium-air batteries, a model is developed for predicting the theoretical capacity of non-aqueous lithium-air batteries. Unlike previous models that were formulated by assuming that the active materials and electrolyte are perfectly balanced according to the electrochemical reaction, the present model takes account of the fraction of the reaction products (Li 2 O 2 and Li 2 O), the utilization of the onboard lithium metal, the utilization of the void volume of the porous cathode, and the onboard excess electrolyte. Results show that the gravimetric capacity increases from 1033 to 1334 mA h/g when the reaction product varies from pure Li 2 O 2 to pure Li 2 O. It is further demonstrated that the capacity declines drastically from 1080 to 307 mA h/g when the case of full utilization of the onboard lithium is altered to that only 10% of the metal is utilized. Similarly, the capacity declines from 1080 to 144 mA h/g when the case of full occupation of the cathode void vol-ume by the reaction products is varied to that only 10% of the void volume is occupied. In general, the theoretical gravimetric capacity of typical non-aqueous lithium-air batteries falls in the range of 380– 450 mA h/g, which is about 10–12% of the gravimetric capacity calculated based on the energy density of the lithium metal. The present model also facilitates the study of the effects of different parameters on the mass and volume change of non-aqueous lithium-air batteries.

    ABSTRACT: The all-solid-state lithium–air cells using lithium anode, the Li1+xAlyGe2−y(PO4)3 inorganic solid electrolyte and the air electrode composed of carbon nanotubes and inorganic solid electrolyte were constructed. The electrochemical performance and reaction mechanism of the cells were investigated in the air atmosphere. The all-solid-state lithium–air cells were successful in discharging and charging. The first discharge and charge capacities were about 1700 mA h g−1 and 900 mA h g−1, respectively, at a current density of 500 mA g−1 in the voltage range of 2.0–4.2 V (vs. Li/Li+). The observed electrochemical redox potential of around 3.1 V (vs. Li) indicated that the electrochemical reaction in the cells is the formation and decomposition of Li2O2. Additionally, the total polarization of 0.2 V, between charge and discharge curves under a low current density, proved that the use of stable solid electrolytes can improve the large polarization observed in the cell using organic liquid electrolytes. However, the presence of both electrochemical and chemical side reactions, in which gases such as water and carbon dioxide in the ambient air were involved, was also suggested and discussed according to experimental results.

    ABSTRACT: The electrochemical performance of rechargeable Li–air batteries containing a reduced graphene oxide (rGO)/α-MnO2 composite and neat α-MnO2 electrode is studied. The rGO/α-MnO2 composite exhibits a specific capacity as high as 558.4 mA h g−1 at a current density of 100 mA g−1, indicating its potential to make a good cathode material. The composite electrode also presents a relatively moderate degradation of capacities with increasing cycles, compared to the neat α-MnO2 electrode. rGO functions as the conducting medium to connect the α-MnO2 nanorods, thus improving the Li ion transfer. The mechanisms responsible for the capacity degradation in the composite electrodes are studied after a series of interrupted charge/discharge cycles, detecting Li2O2 and LiF as the main reaction products formed on the electrode surface. In particular, the LiF layer is identified to be an important component of reaction products, which serves as a barrier to reactions between the Li ions and electrons with the electrode, giving rise to detrimental effects on the cyclic and capacity performance of Li–air batteries.
