摘要： The gravimetric and volumetric efficiency of lithium ion batteries may be increased if high capacity materials like tin and silicon may be employed as the lithium-accepting host in the negative electrode of the battery. But both tin and silicon, when fully charged with lithium, undergo expansions of up to 300% and generate appreciable internal stresses which have potential to spall off material from the electrode on each discharge-charge cycle, resulting in a progressive reduction in battery capacity, also known as battery fade. A method of reinforcing such electrode materials by incorporating within them fiber reinforcements or shaped, elongated reinforcements fabricated of shape memory alloy is described. Electrode materials incorporating such reinforcements are less prone to damage under applied stress and so less prone to battery fade.

摘要： An energy harvesting system comprises a first region having a first temperature and a second region. A conduit is located at least partially within the first region. A heat engine configured for converting thermal energy to mechanical energy includes a shape memory alloy forming at least one generally continuous loop. The shape memory alloy is disposed in heat exchange contact with the first region and the second region. The shape memory alloy is driven to rotate around at least a portion of the conduit by the response of the shape memory alloy to the temperature difference between the first region and the second region. At least one pulley is driven by the rotation of the shape memory alloy, and the at least one pulley is operatively connected to a component to thereby drive the component.

摘要： An energy harvesting system for converting thermal energy to mechanical energy includes a heat engine that operates using a shape memory alloy active material. The shape memory alloy member may be in thermal communication with a hot region at a first temperature and a cold region at a second temperature lower than the first temperature. The shape memory alloy material may be configured to selectively change crystallographic phase between martensite to austenite and thereby one of contract and expand in response to the first and second temperatures. A driven component, such as an electric generator, may be selectively coupled with the heat engine through a coupling device, which may be controlled via a controller.

摘要： Shape memory alloy (SMA) actuating elements are commonly simpler and of lower mass than alternative actuator designs and may find particular application in the transportation industry. Such SMA-powered devices are usually reliable and long-lived but the phase transformations which occur in the SMA alloy and are responsible for its utility are not totally reversible. This irreversibility, a consequence of irrecoverable strain, may progressively degrade the long-term actuator performance as the irrecoverable strain accumulates over many operating cycles. Methods and devices for compensating for these effects and extending the useful cycle life of SMA actuators are described.
摘要翻译： 形状记忆合金（SMA）致动元件通常比替代致动器设计更简单并且质量更低，并且可以在运输行业中找到特定应用。 这种SMA供电的设备通常是可靠的和长寿命的，但SMA合金中发生的并且对其效用负责的相变不是完全可逆的。 这种不可逆转性是不可恢复的应变的结果，随着不可恢复的应变在许多操作循环中积累，可能逐渐降低长期致动器性能。 描述了用于补偿这些影响并延长SMA致动器的有用循环寿命的方法和装置。
