Note:
For many intelligence missions, reliable rechargeable batteries are a key enabler for the integrated circuit (IC) in portable devices. Furthermore, the power needs for IC in some intelligence missions are far more challenging than those of the private sector due to the device operation in extreme environments. Among the available rechargeable batteries, Li-S batteries have become quite attractive for the novel power solution because of their achievable high energy density of ~ 600Wh/kg that is up to three times larger than that of the commercial Li-ion batteries. We propose a nano-engineered Li-S battery based on a novel hybrid electrolyte and our invented technologies of MoS2 coated Li-metal anode and 2D TMDs catalysts deposited 3D C-S cathode to achieve the target metrics. The hybrid electrolyte structure can prevent electrolyte consumption caused by the reaction of electrolytes with active materials resulting in much longer cycle life and capacity retention achieving the Navy’s requirements.
