Abstract: Disclosed is a carbon product, including a carbon material, and a redox functional group-containing polymer layer on a surface of the carbon material, as well as a sulfur-carbon composite containing the same, and a lithium secondary battery containing the same. More specifically, since the redox functional group-containing polymer functions to promote the reduction of lithium polysulfide, when the carbon material having the redox functional group-containing polymer layer formed or the sulfur-carbon composite is applied as a positive electrode material for a lithium secondary battery, the performance of the battery may be improved.

Abstract: The invention discloses a zinc organic battery having a container. The container contains a positive electrode active material, a positive electrode current collector, an organic solvent, a zinc negative electrode, and an aqueous electrolyte. The organic solvent and the aqueous electrolyte are not miscible and are layered due to different densities. The positive electrode active material has a redox activity, and has the two forms of an oxidized state and a reduced state. If the positive electrode active material itself is a liquid and is difficult to be dissolved in the aqueous electrolyte, then the organic solvent may be omitted. The positive electrode active material itself doubles as the organic solvent and is layered with the aqueous electrolyte. The zinc negative electrode is immersed in the aqueous electrolyte and is not in contact with the organic solvent. The aqueous electrolyte is an aqueous solution containing a zinc salt.

Abstract: Bipolar electrodes comprising a carbon felt loaded with a polymer material and a nanocarbon material are described herein. The bipolar electrodes are useful in electrochemical cells. In particular, the loaded carbon felt can be used in bipolar electrodes of zinc-halide electrolyte batteries. Processes for manufacturing the loaded carbon felt are also described, involving contacting (e.g., dipping) a carbon felt in a mixture of solvent, polymer material and nanocarbon material.

Abstract: A porous amorphous silicon which enables improvement in battery performances such as charge/discharge efficiency and battery capacity when used as the anode material; a method for producing a porous amorphous silicon, capable of producing a porous amorphous silicon composed entirely of amorphous silicon at relatively low cost in a short time; and a secondary battery using the porous amorphous silicon as the anode material. A molten metal containing metal and silicon is cooled at a cooling rate of 106 K/sec or more to form an eutectic alloy including the metal and the silicon, and then the metal is selectively eluted from the eutectic alloy with an acid or an alkali to obtain a porous amorphous silicon. The porous amorphous silicon has a lamellar or columnar structure having a mean lamellar diameter or a mean column diameter of 1 nm to 100 nm.

Abstract: Disclosed in the invention is a zinc-iodine battery structure, which includes a housing, a cavity is formed in the housing, and a cation exchange membrane for dividing the cavity into two parts is disposed in a middle of the cavity; a glass fiber component for protecting the cation exchange membrane is disposed at a negative output end; a graphite felt impregnated with a ZnI2 solution is disposed on an outside of the glass fiber component; and the graphite felt of the negative output end is coated with Bi powder, and a graphite felt of a positive output end is coated with Sm powder. Carbon plates serving as current leading-out channels of a battery are disposed on outsides of the graphite felts; and a return flow channel is disposed between the two graphite felts. By using a homogeneous cation exchange membrane with a low electrical resistance, a problem of serious self-discharging is overcome; and by using a flow battery with an open flow system, a problem of a change in pressure caused by a change in volume during charging and discharging is effectively solved. By disposing glass fiber products on two sides of the cation exchange membrane, a dendritic crystal generated during charging is unable to reach a separator, so that short circuit caused by puncture of the separator is avoided.
