    • The present invention generally relates to batteries or other electrochemical devices, and systems and materials for use in these, including novel electrode materials and designs. In some embodiments, the present invention relates to small-scale batteries or microbatteries. For example, in one aspect of the invention, a battery may have a volume of no more than about 5 mm, while having an energy density of at least about 400 W h/1. In some cases, the battery may include a electrode comprising a porous electroactive compound. In some embodiments, the pores of the porous electrode may be at least partially filled with a liquid such as a liquid electrolyte. The electrode may be able to withstand repeated charging and discharging. In some cases, the electrode may have a plurality of protrusions and/or a wall (which may surround the protrusions, if present); however, in other cases, there may be no protrusions or walls. The electrode may be formed from a unitary material. In certain embodiments, a nonporous electrolyte may be disposed onto the electrode. Such an electrolyte may allow ionic transport (e.g., of lithium ions) while preventing dendritic formation due to the lack of pores. In certain embodiments the porous electrode has a surface that is denser than its interior. Other aspects of the invention are directed to techniques of making such electrodes or batteries, techniques of forming electrical connections to and packaging such batteries, techniques of using such electrodes or batteries, or the like.
    • 本发明一般涉及电池或其他电化学装置,以及用于其中的系统和材料,包括新型电极材料和设计。 在一些实施例中,本发明涉及小型电池或微电池。 例如,在本发明的一个方面,电池可以具有不超过约5mm的体积,同时具有至少约400Wh / l的能量密度。 在一些情况下,电池可以包括包含多孔电活性化合物的电极。 在一些实施方案中,多孔电极的孔可以至少部分地填充有诸如液体电解质的液体。 电极可以承受反复的充电和放电。 在一些情况下,电极可以具有多个突起和/或壁(如果存在则可以围绕突起); 然而,在其他情况下,可能没有突起或壁。 电极可以由整体材料形成。 在某些实施方案中,可以在电极上设置无孔电解质。 这样的电解质可以允许离子迁移(例如,锂离子),同时防止由于缺少孔而引起的树突状形成。 在某些实施例中,多孔电极具有比其内部更致密的表面。 本发明的其它方面涉及制造这种电极或电池的技术,形成与这种电池的电连接和包装的技术,使用这种电极或电池的技术等。

    • Systems and methods utilizing solar-electrical generators are discussed. Solar-electrical generators are disclosed having a radiation-capture structure and one or more thermoelectric converters. Heat produced in a capture structure via impingement of solar radiation can maintain a portion of a thermoelectric converter at a high temperature, while the use of a low temperature at another portion allows electricity generation. Thus, unlike photovoltaic cells which are generally primarily concerned with optical radiation management, solar thermoelectrics converters are generally concerned with a variety of mechanisms for heat management. Generators can include any number of features including selective radiation surfaces, low emissivity surfaces, flat panel configurations, evacuated environments, and other concepts that can act to provide thermal concentration. Designs utilizing one or more optical concentrators are also disclosed.
    • 讨论了利用太阳能发电机的系统和方法。 公开了具有辐射捕获结构和一个或多个热电转换器的太阳能发电机。 通过太阳辐射的冲击在捕获结构中产生的热可以将热电转换器的一部分保持在高温,而在另一部分使用低温允许发电。 因此,与通常主要涉及光辐射管理的光伏电池不同,太阳能热电转换器通常涉及各种用于热管理的机构。 发电机可以包括任何数量的功能,包括选择性辐射表面,低辐射面,平板配置,抽真空环境以及其他可提供热集中作用的概念。 还公开了利用一个或多个聚光器的设计。
