Numerous studies have addressed the commercial viability of lithium–air batteries (LABs). However, the high reactivity of Li with air moisture and CO₂ has hindered the broad applicability of LABs. In this study, lithium-protective hybrid lithium–air batteries (HLABs) were fabricated with Super P (SP) and composites of fluorinated carbon (CF_x), MoS₂, and WS₂ as the cathodes. Subsequently, their potential use as a power source for the next generation of defense technologies was investigated. It was observed that a single cell HLAB with the SP-CF_x composite cathode exhibited a specific capacity of 893 mAhg⁻¹_cathode. In comparison, a Tomcell with the SP cathode demonstrated a specific capacity of 465 mAhg⁻¹_cathode when discharged. The cells with SP-MoS₂ and SP-WS₂ cathode yielded specific capacities of 357 and 386 mAhg⁻¹_cathode, respectively. The improved performance of the SP-CF_x cell can be attributed to synergistic effects of lithium–air cell and lithium battery reactions between CF_x and SP. To assess all functionalities of the SP-CF_x HLAB, lithium-protective HLABs were fabricated and discharged in air. To operate the lithium–air battery in air, pure lithium metal was sealed with solid electrodes (lithium-ion conducting glass–ceramics (LICGC)) and a buffer electrolyte (1 M LiFTSI in TEGDME) was applied. The SP-CF_x cell was discharged for 25 days in air, greatly exceeding the 72 h requirement for the next-generation soldier power systems. These results demonstrate significant potential for HLABs to be used as a pioneering power source in next-generation energy-independent tactical defense units.

大量研究已经解决了锂空气电池（LABs）的商业可行性。但是，Li与空气中的水分和CO ₂的高反应性阻碍了LABs的广泛应用。在本研究中，使用Super P（SP）和氟化碳（CF _x），MoS ₂和WS _2的复合材料作为阴极，制造了锂保护混合型锂空气电池（HLAB）。随后，研究了它们作为下一代国防技术动力的潜在用途。观察到带有SP-CF _x复合阴极的单电池HLAB的比容量为893 mAhg ^-1_阴极。相比之下，带有SP阴极的Tomcell在放电时显示的比容量为465 mAhg ^-1_阴极。具有SP-MoS ₂和SP-WS ₂阴极的电池的比容量分别为357和386 mAhg ^-1_阴极。SP-CF _x电池性能的提高可归因于CF _x 和SP之间锂空气电池和锂电池反应的协同效应。评估SP-CF _x的所有功能制备了HLAB，锂保护性HLAB，并将其排放到空气中。为了在空气中运行锂空气电池，请使用固体电极（锂离子传导玻璃陶瓷（LICGC））密封纯锂金属，并使用缓冲电解质（TEGDME中的1 M LiFTSI）。SP-CF _x电池在空气中排放了25天，大大超过了下一代士兵动力系统的72小时要求。这些结果表明，HLAB在下一代独立于能源的战术防御单位中被用作开拓性能源的巨大潜力。
