reproduction of li battery linixmnyco1 x yo2 Positive Electrode material from the recycling of waste battery
International Journal of Hydrogen Energy, 2017Co-Authors: Yenchun Liu, Minchi LiuAbstract:Abstract In this study, Co, Li and Ni were acquired from waste battery to remake Positive Electrode material of Li battery, then the battery was assembled and battery charging and discharging was conducted. By doing so, the waste can be turned into resource, and pollution issue to the environment from the battery can be reduced and manufacturing cost of the battery can be reduced too. Presently, the recycling treatment of waste Li battery was to adopt wet metallurgical method to separate Li, Co, Ni and Mn elements and to prepare respectively all kinds of pure oxide or carbonate, therefore, the process was very tedious, and the economic efficiency was not as expected. In this study, Co, Li and Ni were acquired from waste battery to make Li, Ni, Mn, Co ternary material Positive Electrode powder. In the process, Li, Ni, Mn and Co proportion in the solution was analyzed, and insufficient metallic ion composition was then added. After it was adjusted to correct composition, it was sintered into Positive Electrode material powder. Therefore, element separation procedure can be saved, and the cost can be greatly reduced. In this study, waste battery was used to remake Positive Electrode material, and SEM and XRD were used first to observe micro structure, then it was assembled into battery. After battery charging and discharging performance test, it can reach 122.21 mA h/g, which was about 88% of that made by pure material. Consequently, the purposes of low manufacturing cost of Positive Electrode material, the recycling of valuable Co material from the waste battery, the reduction of waste material and the turning of waste into resource can be reached.

Copper chloride as a conversion-type Positive Electrode for rechargeable aluminum batteries
RSC Advances, 2019Co-Authors: Masanobu Chiku, Takeshi Kunisawa, Eiji Higuchi, Hiroshi InoueAbstract:Copper chloride (CuCl2) was investigated for the first time as conversion-type Positive Electrode material in a rechargeable Al battery. The Electrode was reversibly charged and discharged in an electrolyte solution of AlCl3, dipropylsulfone, and toluene (1 : 10 : 5 molar ratio). The initial discharge capacity was about 370 mA h (g-CuCl2)−1 at 0.028C-rate (11 mA (g-CuCl2)−1), which was almost the same as the theoretical value (399 mA h (g-CuCl2)−1) and higher than that of insertion-type Positive Electrode materials as used in the rechargeable Al battery. Moreover, a two-stage discharge plateau voltage was observed at 1.5 V and 0.8 V, which was higher than other conversion type Positive Electrodes for the aluminum rechargeable battery. The high discharge voltage realized a high energy density of 426 mW h (g-CuCl2)−1, which is the highest energy density compared with other conversion type Positive Electrodes. Two different strategies were implemented to increase the lifetime of the cell, namely, increasing the upper cut-off voltage and decreasing the particle size of CuCl2. The discharge capacity for the Electrode at the second cycle was threefold that for a pristine CuCl2 Electrode.

amorphous vanadium oxide carbon composite Positive Electrode for rechargeable aluminum battery
ACS Applied Materials & Interfaces, 2015Co-Authors: Masanobu Chiku, Eiji Higuchi, Hiroki Takeda, Shota Matsumura, Hiroshi InoueAbstract:Amorphous vanadium oxide/carbon composite (V2O5/C) was first applied to the Positive Electrode active material for rechargeable aluminum batteries. Electrochemical properties of V2O5/C were investigated by cyclic voltammetry and charge-discharge tests. Reversible reduction/oxidation peaks were observed for the V2O5/C Electrode and the rechargeable aluminum cell showed the maximum discharge capacity over 200 mAh g(-1) in the first discharging. The XPS analyses after discharging and the following charging exhibited that the redox of vanadium ion in the V2O5/C active material occurred during discharging and charging, and the average valence of V changed between 4.14 and 4.85.

All-solid-state lithium battery with sulfur/carbon composites as Positive Electrode materials
Solid State Ionics, 2014Co-Authors: Shunji Kinoshita, Nobuya Machida, Kazuya Okuda, Muneyuki Naito, Toshihiko SigematsuAbstract:Abstract Sulfur–carbon composites were investigated as Positive Electrode materials for all-solid-state lithium ion batteries with an inorganic solid electrolyte (amorphous Li3PS4). The elemental sulfur was mixed with Vapor-Grown Carbon Fiber (VGCF) and with the solid electrolyte (amorphous Li3PS4) by using high-energy ball-milling process. The obtained sulfur–VGVF–solid electrolyte composite was used as Positive Electrode materials of the all-solid-state battery. The composite showed good electrochemical properties as Positive Electrode materials. The capacity that was calculated on the base of the weight of sulfur was about 1300 mAhg− 1 at room temperature, when the all-solid-state battery was discharged and charged in the voltage range of 0.9 to 2.6 V at a constant current density of 0.1 mAcm− 2. The battery kept the capacity more than 1200 mAhg− 1 even after 50 discharge–charge cycles.
