摘要:
A glass-based material is proposed as additive for a rechargeable lithium ion storage battery with liquid electrolyte for stabilizing the conducting salt in the electrolyte, the glass-based material consisting of glass or a glass ceramic and comprising in particular network modifiers in the form of Lewis bases having high optical basicity, such as BaO, Li 2 O or ZrO, for example.
摘要:
The invention relates to a material based on glass which is suitable for producing a separator for an electrochemical energy accumulator, in particular for a lithium-ion accumulator. Said glass-based material contains the following components (in wt. % based on oxide): SiO 2 + F + P 2 O 5 20 - 95; Al 2 O 3 0,5 - 30, wherein the density is less than 3.7 g/cm 3 .
摘要:
A method for producing perforated work pieces from glass, glass ceramics, or semiconductors in a stress-relieving manner is provided. The method includes heating the work piece up to the glass transition temperature and perforating the work piece using a high-voltage electric field of suitable frequency or pulse shape. Then, the perforated work piece is allowed to cool down from the transition temperature range to room temperature at a rate at which the mechanical stresses generated by the perforation process relax.
摘要:
According to the invention, the signal quality on passing through a device for the transmission of optical signals, comprising a waveguide with a doped region, containing a material suitable for the amplification of optical signals may be impaired as little as possible, whereby the doped region has a pre-defined absorption and may have the amplification thereof altered by the injection of pumping light.
摘要:
An apparatus for producing holes in dielectric workpieces in the form of thin sheets and substrates, in particular of glass or glass-like materials and semiconductors is provided. The apparatus includes individual high-voltage electrodes that are symmetrically arranged on an electrode holder around the hole to be produced in the workpiece. The apparatus also includes individual counter electrodes that are arranged on a counter electrode holder. The electrodes and counter electrodes can be connected in a permutating manner to a high-voltage source for the discharge of high-voltage flashovers.
