Publication number: 20150144494Abstract: The gravimetric and volumetric efficiency of lithium ion batteries may be increased if higher capacity materials like tin and silicon are substituted for carbon 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. These internal stresses, which will develop on each discharge-charge cycle, may lead to a progressive reduction in battery capacity, also known as battery fade. The effects of the internal stresses may be significantly reduced by partially embedding tin or silicon nanowires in the current collector. Additional benefit may be obtained if a 5 to 50% portion of the nanowire length at its embedded end are coated or masked with a composition which impedes lithium diffusion. Methods for embedding and masking the nanowires are described.Type: ApplicationFiled: February 3, 2015Publication date: May 28, 2015Inventors: Mark W. Verbrugge, Sampath K.

Publication number: 20140268076Abstract: A dynamic pattern generator (DPG) device and method of making a DPG device are disclosed. The DPG device is used in semiconductor processing tools that require multiple electron-beams, such as direct-write lithography. The device is a self-aligned DPG device that enormously reduces the required tolerances for aligning the various electrode layers, as compared to other design configurations including the non-self-aligned approach and also greatly simplifies the process complexity and cost. A process sequence for both integrated and non-integrated versions of the self-aligned DPG device is described. Additionally, an advanced self-aligned DPG device that eliminates the need for a charge dissipating coating or layer to be used on the device is described. Finally, a fabrication process for the implementation of both integrated and non-integrated versions of the advanced self-aligned DPG device is described.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: CORPORATION FOR NATIONAL RESEARCH INITIATIVESInventor: CORPORATION FOR NATIONAL RESEARCH INITIATIVES
