A porous polymer sheet or membrane is provided with a thin coating of an electrically non-conductive ceramic composition and the coating conforms to all surfaces, including the pore surfaces, of the membrane. Such a coated membrane serves well, for example, as an intra-cell separator in a lithium ion battery. The coating increases the mechanical properties and thermal stability of the separator in battery operation and retains electrolyte. The coating may be formed by a two-step vapor-phase process in which atoms of one or more metals such as aluminum, calcium, magnesium, titanium, silicon and / or zirconium are deposited in a conformal layer on a workpiece surface. The metal atoms may then be reacted with ammonia, carbon dioxide, and or water to form their respective non-conductive nitrides, carbides, and / or oxides on the surface. The two-step process is repeated as necessary to obtain a ceramic material coating of desired thickness.

The gravimetric and volumetric efficiency of lithium ion batteries may be increased if high capacity materials like tin and silicon may be employed 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 which have potential to spall off material from the electrode on each discharge-charge cycle, resulting in a progressive reduction in battery capacity, also known as battery fade. A method of reinforcing such electrode materials by incorporating within them fiber reinforcements or shaped, elongated reinforcements fabricated of shape memory alloy is described. Electrode materials incorporating such reinforcements are less prone to damage under applied stress and so less prone to battery fade.

An organic light emitting diode (OLED) display is provided. The OLED display includes: a substrate member; an OLED that includes a pixel electrode that is formed on the substrate member, an organic light emitting layer that is formed on the pixel electrode, and a transflective common electrode that is formed on the organic light emitting layer; an encapsulation thin film that is formed on the transflective common electrode; and a touch panel that includes a first touch conductive layer that is formed on the encapsulation thin film and that is formed with a transflective metal film, a glass substrate that is formed on the first touch conductive layer, and a second touch conductive layer that is formed on the glass substrate. In some embodiments, the transflective common electrode has reflectivity of less than 50%. Some of the external light is thus reflected again to the first touch conductive layer and back to the transflective common electrode and so on. During this cycling, destructive interference occurs and the cycled light eventually dissipates. Thus, unwanted reflected light is suppressed.
