    摘要： According to the process of this invention, first a manganese oxide seed is prepared, which is then grown to obtain manganese oxide having large particle diameters. The manganese oxide thus obtained is reacted with a lithium compound, whereby lithium manganate having large particle diameters can be obtained. Since the lithium manganate has large particle diameters and gives a high packing density, lithium batteries with a high energy density can be provided by using the lithium manganate.

    摘要： A process for manufacture of manganese dioxide comprising subjecting an aqueous bath comprising manganese sulfate (MnSO4) and sulfuric acid (H2SO4) to electrolysis in a closed cell wherein the electrolysis bath is maintained at an elevated temperature above 110null C., preferably above 115null C. and at superatmospheric pressure. Desirably the bath can be maintained at an elevated temperature between about 115null C. and 155null C. The electrolysis is carried out preferably at elevated current density of between about 12.5 and 37 Amp/sq.ft (135 and 400 Amp/sq. meter) of the anode surface which allows for smaller or fewer electrolysis units. An MnO2 product having a specific surface area (SSA) within desired range of between 18-45 m2/g can be obtained. A doping agent, preferably a soluble titanium dopant can also be employed to help obtain the desired specific surface area (SSA) of the MnO2 product. The manganese dioxide product when used as cathode active material in zinc/MnO2 alkaline cells results in excellent service life, particularly when the cell is used in high power application.

    摘要： The present invention provides a lithium-ion secondary battery whose power characteristic has been improved without widening a battery size. A cylindrical lithium-ion battery 20 accommodates a winding group 6 and a non-aqueous electrolytic solution within a battery container 7. The winding group 6 is structured by winding a positive electrode using lithium manganate (Li1nullxMn2nullxO4 or Li1nullxMn2nullxnullyAlyO4) where an average particle diameter of primary particles is in a range of from 0.1 nullm to 2 nullm as a positive electrode active material and a negative electrode using amorphous carbon as a negative electrode active material via a separator. The reaction area of the positive electrode active material is optimized.

    摘要： The present invention relates to a new sandwich cathode design having two cathode active materials provided on opposite sides of a current collector. The respective active materials are similar in terms of, for example, their rate capability, their energy density, or some other parameter. However, one material may have an advantage over the other in one characteristic, but is disadvantageous in another. The cathode is built in a sandwich configuration having a first one of the active materials sandwiched between two current collectors. Then, the second active material is provided in contact with at least the other side of one of the current collectors, and preferably facing the anode. An exemplary cathode has the following configuration: MnO2/current collector/SVO/current collector/MnO2.
