Abstract: An electrode composition comprises a silicon powder comprising non-crystalline and crystalline silicon, where the crystalline silicon is present in the silicon powder at a concentration of no more than about 20 wt. %. An electrode for an electrochemical cell comprises an electrochemically active material comprising non-crystalline silicon and crystalline silicon, where the non-crystalline silicon and the crystalline silicon are present prior to cycling of the electrode. A method of controlling the crystallinity of a silicon powder includes heating a reactor to a temperature of no more than 650° C. and flowing a feed gas comprising silane and a carrier gas into the reactor while maintaining an internal reactor pressure of about 2 atm or less. The silane decomposes to form a silicon powder having a controlled crystallinity and comprising non-crystalline silicon.

Abstract: Microscale and/or nanoscale structural features are formed in material by using an ultrashort pulsed laser (e.g., a femtosecond pulsed laser). Methods of forming such structures comprise applying laser energy generated by an ultrashort pulsed laser to a surface of a substrate having a first layer and a distinct second layer. The first layer has a first ablation threshold that is less than the applied laser energy and the second layer has a second ablation threshold that is greater than the applied laser energy. The laser energy penetrates through the second layer to the first layer. The applied laser energy results in damage (or an ablation event) at the first layer that exerts force sufficient to delaminate the second layer, thereby forming a void space that is a channel having a major elongate axis or alternately forming an open groove.
