摘要:
A method for improving the environmental stability of cathode materials used in lithium-based batteries. Most currently used cathode active materials are acutely sensitive to environmental conditions, e.g. leading to moisture and CO2 pickup, that cause problems for material handling especially during electrode preparation and to gassing during charge and discharge cycles. Binder materials used for making cathodes, such as PVDF and PTFE, are mixed with and/or coated on the cathode materials to improve the environmental sensitivity of the cathode materials.

Methods and systems for three dimensional large area welding and sealing of optically transparent materials are disclosed, including generating a beam of ultra-short pulses from an ultra-short pulsed laser; directing the beam to an acoustic-optic modulator to control the repetition rate of the beam; directing the beam to an attenuator after passing through the acoustic-optic modulator to control the energy of the beam; directing the beam to a focusing lens after passing through the attenuator to focus the beam between a top substrate and a bottom substrate in order to weld the top substrate to the bottom substrate, wherein the top substrate and the bottom substrate are in intimate contact; and controlling the position of the top substrate and the bottom substrate relative to the beam using a three-axis stage in order to weld the top substrate to the bottom substrate at different points. Other embodiments are described and claimed.

摘要:
The invention is involved in epimeredinoside A with its structure showed below, and the preparative methods of the pharmaceutics made from Epimeredi indica root extract containing epimeredinoside A. It includes all kinds of oral pharmaceutics made up with Epimeredi indica root extract and pharmaceutical adjuvant. The root extract is the extracta sicca prepared by water extracted and concentrated of Epimeredi indica root, containing 0.10% to 1.50% of epimeredinoside A. The invention, pharmaceutics of Epimeredi indica root extract DO NOT contain any hormone. NO progesterone is needed to be intaken to prevent the side effect after using the drug. The pharmaceutics has doubtless effect in clinic, and is stability, controllable and safety, especially compatible for the female menopause.
