Flash-cooled freestanding silicon particles are provided for electrochemical use. The particles are solidified from a vapor or molten phase at a cooling rate of at least about 1×103 degrees Celsius per second. The particles have a major dimension less than 1 micron, comprising silicon, and an electrically conductive component within the freestanding submicron particles having an electrical conductivity higher than that of silicon. The silicon is in the form of elemental silicon or lithiated silicon, and the electrically conductive component has a weight ratio to the silicon in the range of from about 0.01 to about 0.25 to 1. The electrically conductive component is in the form of electrically conductive zones within the flash-cooled freestanding silicon particles.
提供了用于电化学用途的闪冷独立硅颗粒。这些颗粒以每秒至少约 1×103 摄氏度的冷却速度从蒸气或熔融相凝固而成。颗粒的主要尺寸小于 1 微米,由硅组成,独立亚微米颗粒内的导电成分的导电率高于硅的导电率。硅的形式为元素硅或锂化硅,导电成分与硅的重量比在约 0.01 至约 0.25 比 1 的范围内。
