    • An electrical energy storage device (10). An electrode (12) consisting of a thin film of metal or metal oxide is deposited on a substrate (24), preferably by sputtering. Spherical plastic spacers (16) are uniformly dispersed on the electrode at a maximum density of about 1000 spacers per square millimeter of the electrode area. A second substrate also has an electrode (14) formed of a thin film of metal or metal oxide deposited on it, similar to the first substrate. The first and second substrates are arranged so that the electrodes face each other and are separated by the spherical plastic spacers to form a gap (18) of about 20 microns between the electrodes. An electrolyte (20) is filled in the gap, and the edges of the gap are optionally sealed (22) to form the electrical energy storage device. The device may also be formed by using metal foils, and eliminating one or more of the substrates. In both cases, the use of an electrolyte is optional.
    • 一种电能存储装置(10)。 优选通过溅射将由金属或金属氧化物薄膜组成的电极(12)沉积在基板(24)上。 球形塑料间隔物(16)以电极面积每平方毫米约1000个间隔物的最大密度均匀分散在电极上。 类似于第一衬底,第二衬底还具有由沉积在其上的金属或金属氧化物薄膜形成的电极(14)。 第一和第二基板被布置成使得电极彼此面对并且被球形塑料间隔物隔开,以在电极之间形成约20微米的间隙(18)。 电解质(20)填充在间隙中,并且间隙的边缘任选地被密封(22)以形成电能存储装置。 该装置还可以通过使用金属箔形成,并且消除一个或多个基板。 在这两种情况下,使用电解质都是可选的。
