摘要： Disclosed is a positive electrode that has a low equivalent weight and high cell voltage and consequently a high specific energy, and a high discharge rate pulse capability. Also disclosed are methods for fabricating active-sulfur-based composite electrodes, and battery cells incorporating such electrodes. The batteries of this invention are preferably rechargeable and operate at high sulfur utilization over many cycles. Positive electrodes according to the present invention are composed of at least two electrochemically active materials: an “active-sulfur” material, and a second electrochemically active material having a higher discharge rate than the active-sulfur component. The active-sulfur component is also oxidizing with respect to the higher discharge rate material. In operation, the active-sulfur component of the positive electrode discharges to satisfy power demands below its maximum discharge rate. The high discharge rate (but relatively low capacity) material is discharged to satisfy power demands that exceed the active-sulfur's discharge rate. The high discharge rate material in the positive electrode may be effectively recharged (or “regenerated”) chemically by oxidation by the active-sulfur material during a “resting” phase, that is, when the power demands on a battery cell in which the cathode is incorporated are low enough that they may be met without exceeding the maximum discharge rate of the active-sulfur component of the positive electrode.
摘要翻译：公开了具有低当量和高电池电压并因此具有高比能量和高放电率脉冲能力的正电极。还公开了制造活性硫基复合电极的方法以及包含这种电极的电池单体。本发明的电池优选是可充电的并且在多个循环中以高硫利用运行。根据本发明的正电极由至少两种电化学活性材料：“活性硫”材料和具有比活性硫组分更高的放电率的第二电化学活性材料组成。相对于较高的排出速率的材料，活性硫成分也是氧化的。在操作中，正极的活性硫成分排出以满足低于其最大放电率的功率需求。高放电率（但容量相对较小）的材料排放满足超过活性硫排放速率的电力需求。正极中的高放电率材料可以通过在“静止”阶段期间被活性硫材料氧化而化学地再充电（或“再生”），即当电力需要电池单元时，其中阴极并不足够超过正极的活性硫成分的最大排出速度，所以能够满足这些要求。

摘要： Aqueous Li/Air secondary battery cells are configurable to achieve high energy density and prolonged cycle life. The cells include a protected a lithium metal or alloy anode and an aqueous catholyte in a cathode compartment. The aqueous catholyte comprises an evaporative-loss resistant and/or polyprotic active compound or active agent that partakes in the discharge reaction and effectuates cathode capacity for discharge in the acidic region. This leads to improved performance including one or more of increased specific energy, improved stability on open circuit, and prolonged cycle life, as well as various methods, including a method of operating an aqueous Li/Air cell to simultaneously achieve improved energy density and prolonged cycle life.

摘要： Provided are lithium sulfur battery cells that use water as an electrolyte solvent. In various embodiments the water solvent enhances one or more of the following cell attributes: energy density, power density and cycle life. Significant cost reduction can also be realized by using an aqueous electrolyte in combination with a sulfur cathode. For instance, in applications where cost per Watt-Hour (Wh) is paramount, such as grid storage and traction applications, the use of an aqueous electrolyte in combination with inexpensive sulfur as the cathode active material can be a key enabler for the utility and automotive industries, providing a cost effective and compact solution for load leveling, electric vehicles and renewable energy storage.

摘要： Protected anode architectures for active metal anodes have a polymer adhesive seal that provides an hermetic enclosure for the active metal of the protected anode inside an anode compartment. The compartment is substantially impervious to ambient moisture and battery components such as catholyte (electrolyte about the cathode), and prevents volatile components of the protected anode, such as anolyte (electrolyte about the anode), from escaping. The architecture is formed by joining the protected anode to an anode container. The polymer adhesive seals provide an hermetic seal at the joint between a surface of the protected anode and the container.
