摘要:
The present invention relates to an electrochemically-gated field-effect transistor (FET) in which the channel length is independent from the printing resolution. The FET comprises an arrangement (11) placed on top of a substrate (10) which consists of a first electrode (1), a second electrode (2) and a transistor channel (4), located between the two electrodes (1, 2), an electrolyte (5), covering the transistor channel (4) completely, and a gate electrode (3). The first electrode (1), comprising a first solid or porous metallic conducting body, is placed on top of the substrate (10). The transistor channel (4), comprising a porous semiconducting material, is placed on top of the first electrode (1), partially covering the first electrode (1). The second electrode (2), comprising a second solid or porous metallic conducting body, is placed on top of the transistor channel (4) which is placed on top of the first electrode (1), at least partially covering the transistor channel (4). The electrolyte (5) penetrates at least through the transistor channel (4) down to the first electrode (1) while leaving a part of each electrode (1, 2) uncovered. The gate electrode (3), comprising a third solid or porous metallic conducting body, is placed in contact with the electrolyte (5) but without any contact to the arrangement (11).

The present invention relates to a composite solid polymer electrolyte which comprises a polymer, a plasticizer, a supporting electrolyte (salt), and a non-aqueous solvent. The present invention further relates to the use of the composite solid polymer electrolyte to be used as dielectrics in low voltage, flexible, bendable, transparent, printed electronics, in particular to manufacture devices including but not limited to logics, circuits, transistors, capacitors. The present invention also relates to printed electronics which is available through depositing a layer of said composite solid polymer electrolyte.
摘要:
The present invention relates to a lithium/graphite fluoride primary battery prepared by a process comprising the steps of (a) Providing an amount of a graphite fluoride powder; (b) Treating the amount of graphite fluoride powder by mechanical milling, by which step an active material is obtained; and (c) Forming an electrochemical cell in which a mixture of the active material and an electrically conducting carbon is assembled as part of the positive electrode and a body comprising lithium is assembled as part of a negative electrode. The present invention further relates to a method for manufacturing such a lithium/graphite fluoride primary battery. By applying mechanical milling to the graphite fluoride powder the particle size of the active material could be considerably reduced which resulted both in a larger BET surface area, an increased value for the total pore volume and a higher tap density. By this measure, both the energy density and the power density of this battery could be considerably improved without losing the high intrinsic specific capacity of the original graphite fluoride powder material.
