Abstract: A method and an electronic apparatus for predictive value decision and a computer-readable recording medium thereof are provided. First, a model operation interface is activated, and in response to receiving an operation through the model operation interface, the following steps are executed. A shipment predictive value at a target time point is calculated based on historical shipment data. Next, a change ratio scale corresponding to the target time point is calculated using the shipment predictive value corresponding to the target time point and multiple previous shipment predictive values at multiple time points before the target time point. Moreover, an average value of past change ratio scales corresponding to the target time point is calculated based on the historical shipment data. Finally, predictive performance information is provided based on the average value of the past change ratio scales and the change ratio scale corresponding to the target time point.

Abstract: A method for producing a positive electrode material adapted to the Li-ion secondary batteries is disclosed. The produced material has the following formula (I), Li1+xMn2?yMyO4 ??(I) wherein M is Mg, Al, Cr, Fe, Co, or Ni; 0?x?0.4, and 0?y?0.2. The method is achieved by co-precipitating a gel salts with an organic acid. First, salts of Li, Mn and M are mixed with at least a solvent to form an initial solution. The mole ratio of Li, Mn and M ions in their respective salts is (1+x):(2?y):y. Next, at least a chelate is added into the initial solution to form a suspension, which is then filtered to obtain a co-precipitate. Finally, the co-precipitate is calcined and heated to obtain the final product.

Abstract: A positive electrode material of a Li-ion secondary battery is disclosed. This positive electrode material has a formula of Li1+xMn2−yMyO4−zClz, wherein M can be magnesium (Mg), aluminum (Al), chromium (Cr), iron (Fe), cobalt (Co) or nickel (Ni) ions, 0≦x≦0.4, 0≦y≦0.3, and 0.01≦z≦1.0. By means of replacing some oxygen ions of this material with chlorine ions, the crystalline structure thereof can be varied and thus longer life cycle and better stability at high temperature can be achieved.
