摘要:
Methods and systems are provided for printing a three-dimensional object. For example, a method includes determining a target thickness for a region of the three-dimensional object. A color for the region is determined. The color is assigned a color density. A color thickness for the color is determined based on the color density. The target thickness is independent from the color thickness. A color layer having the color thickness in the region is printed. A structural thickness for a structural layer of the region is determined based on the color thickness and the target thickness. The structural layer having the structural thickness is printed directly onto the color layer. A combination of the color layer and the structural layer has the target thickness.

摘要:
A method of preparing a high capacity nanocomposite cathode of FeF3 in carbon pores may include preparing a nanoporous carbon precursor, employing electrochemistry or solution chemistry deposition to deposit Fe particles in the carbon pores, reacting nano Fe with liquid hydrofluoric acid to form nano FeF3 in carbon, and milling to achieve a desired particle size.
摘要:
Methods and systems to determine an internal temperature of a rechargeable lithium-ion cell based on a phase shift of the cell. Internal cell temperature may be determined with respect to an internal anode temperature and/or an internal cathode temperature. Internal anode temperature may be determined based on a phase shift of a frequency within a range of approximately 40 Hertz (Hz) to 500 Hz. Internal cathode temperature may be determined based on a phase shift of a frequency of up to approximately 30 Hz. A temperature sensor as disclosed herein may be powered by a monitored cell with relatively little impact on cell charge, may be electrically coupled to cell but housed physically separate from the cell, and/or may monitor multiple cells in a multiplex fashion. A rate of change in phase shift may be used to initiate pre-emptive action, without determining corresponding temperatures.
