When semi-amorphous TFTs are used for forming a signal line driver circuit and a pixel, a large amplitude is required for driving the pixel, and a large power supply voltage is thus needed. On the other hand, when a shift register is made up of transistors having a single conductivity, a bootstrap circuit is required, and a voltage over a power supply is applied to a specific element. Therefore, not both the driving amplitude and the reliability can be achieved with a single power supply. According to the invention, a level shifter having a single conductivity is provided to solve such a problem.

A lithium secondary battery includes an anode mix including a silicon- or tin-based material as an anode active material, a thermosetting agent, and a curing agent and a curing accelerator as a binder. The anode mix is prepared within a short period of time via a simplified manufacturing process by applying the anode mix to a current collector and heating to cure the applied anode mix at a temperature of less than 200° C.

The invention relates to a method for priming a substrate by contacting the substrate with a primer fed from a primer source and depositing the primer on the substrate. Compared to other priming methods, the claimed priming gives better results because the deposition is carried out electrostatically.

Disclosed is a lithium iron phosphate with an olivine crystal structure wherein the lithium iron phosphate has a composition represented by the following Formula 1 and carbon (C) is coated on the surface of the lithium iron phosphate by chemical bonding via a heterogeneous element other than carbon. Li1+aFe1−xMx(PO4−b)Xb (1) (wherein M, X, a, x, and b are the same as defined in the specification).

An instant water heater utilizing positive temperature coefficient plastic electrically conductive material structures for electrodes. The heating of the water is not generated by the electrodes, but instead by the resistance of the water to the electrical current flowing between them. The material of the electrodes undergoes a phase change at certain temperatures when whereby it converts from electrically conductive to electrically non-conductive at a predetermined temperature. The output temperature of the water is determined by a combination of the area of the electrodes that confront one another, the water's conductivity, the flow rate of the water and the current limiting capability of the conductive electrode materials positive temperature coefficient, which reduces or stops the heating of the water when the intended water temperature is achieved.

Disclosed is an anode for secondary batteries comprising a combination of an anode active material having a relatively low charge / discharge voltage and a relatively low hardness (A) and an anode active material having a relatively high charge / discharge voltage and a relatively high hardness (B), wherein the anode active material (A) is surface-coated with carbon having a high hardness or a composite thereof, and a particle size of the anode active material (B) is smaller than a size of a space formed by the anode active materials (A) arranged in a four-coordination. The anode provides an electrode that prevents lithium precipitation caused by overvoltage, improves ionic conductivity as well as electric conductivity and exhibits superior capacity.

Disclosed is a cathode for secondary batteries comprising a compound having a transition metal layer containing lithium as at least one compound selected from the following formula 1: (1−x)Li(LiyM1-y-zMaz)O2-bAb*xLi3PO4 (1) wherein M is an element stable for a six-coordination structure, which is at least one selected from transition metals that belong to first and second period elements; Ma is a metal or non-metal element stable for a six-coordination structure; A is at least one selected from the group consisting of halogen, sulfur, chalcogenide compounds and nitrogen; 0<x<0.1; 0<y<0.3; 0≦z<0.2; and 0≦b<0.1.

Disclosed are an anode active material for secondary batteries, capable of intercalating and deintercalating ions, the anode active material including a core including a crystalline carbon-based material, and a composite coating layer including one or more materials selected from the group consisting of low crystalline carbon and amorphous carbon, and a hydrophilic material, wherein the composite coating layer includes a matrix comprising one component selected from one or more materials selected from the group consisting of low crystalline carbon and amorphous carbon, and a hydrophilic material, and a filler including the other component, incorporated in the matrix, and a secondary battery including the anode active material.

Disclosed is lithium iron phosphate having an olivine crystal structure wherein carbon (C) is coated on particle surfaces of the lithium iron phosphate, wherein, when a powder of the lithium iron phosphate is dispersed in water, water is removed from the resulting dispersion and the resulting lithium iron phosphate residue is quantitatively analyzed, a ratio of the carbon-released lithium iron phosphate with respect to the total weight of the carbon-coated lithium iron phosphate is 0.005% by weight or less. Advantageously, the olivine-type lithium iron phosphate is not readily separated through uniform thin film coating on the surface of the lithium iron phosphate and exhibits superior conductivity and density, since carbon is coated on particle surfaces of lithium iron phosphate in a state in which the amount of carbon released in water is considerably small.
