An electrode structural body comprising a plate-like shaped collector having opposite surfaces and an electrode material layer formed an at least one of said opposite surfaces of said collector, wherein said electrode material layer contains 35% by weight or more of a grained host matrix material of 5 to 60 in average particle size. A rechargeable battery provided with said electrode structural body as an electrode thereof.

Electrode structural body, rechargeable battery provided with said electrode structural body, and rechargeable battery

A secondary battery comprises a negative electrode and a positive electrode which oppose each other and an ion conductive member which includes a layered or columnar structure (ion channels) in its matrix and which is sandwiched between the negative electrode and the positive electrode.

Secondary battery having an ion conductive member and manufacturing process thereof

A liquid crystal apparatus includes (a) a liquid crystal panel including: a pair of substrates having thereon a group of scanning electrodes and a group of data electrodes, respectively, and provided with mutually different alignment characteristics, and a chiral smectic liquid crystal disposed between the substrates so as to form a pixel at each intersection of the scanning electrodes and the data electrodes, and (b) drive means for: sequentially applying a scanning selection signal to the scanning electrodes to select at least one scanning electrode, and applying a data signal having at least three peak values to the data electrodes in synchronism with the scanning selection signal. A DC bias voltage may be applied between the scanning electrodes and the data electrodes, and the polarity of the DC voltage may be switched for each prescribed period. The above system is suitable for obviating or suppressing the 'sticking' phenomenon of a chiral smectic liquid crystal.
