The application discloses anode-oxidizable super-high-strength aluminum alloy and a preparation method thereof. Al 83.85~90.46wt%, Mg 6.0~9.5wt%, Zn 3.51~5.0wt%, Si 0.025~0.45wt%, and at least one of Mn, Cu, Ti, Be, Sb elements with a total content of not more than 0.70wt%, wherein the content of Mg, Zn and Si satisfies the relationship formula: -3.3≤[(2.31×Si)+(1.76×Zn)-Mg]×100≤3.6, and the grain length-diameter ratio is ≤3. The preparation method of the aluminum alloy deformed material comprises the following steps: (1) manufacturing an aluminum alloy ingot; (2) homogenizing heat treatment; (3) processing into a processing material; (4) solid solution heat treatment on the processing material; (5) cooling to room temperature; and (6) aging treatment. The aluminum alloy has low density, high strength and excellent surface treatment adaptability.

The present application relates to a solar cell comprising: a silicon substrate containing an Sb element; an aluminum oxide layer formed on the silicon substrate; wherein the aluminum oxide layer contains antimony. The present application also relates to a photovoltaic module comprising the solar cell.

The application belongs to the technical field of battery materials, and discloses a kind of secondary ball positive active material, the primary particle of the secondary ball positive active material is doped with Sb and S.By the common doping of S and Sb element, the primary particle of the secondary ball is reduced, the uniformity of the primary particle is improved, which is beneficial to reduce the migration resistance, improve the cycle performance and the first coulomb efficiency of the material.The preparation method of the secondary ball positive active material is also disclosed, the S-containing compound and the Sb-containing compound are added simultaneously in the primary mixing process, which can effectively control the size of the primary particle, and the simultaneous addition of the two elements can make the primary particle smaller and more close to the spherical particle, and the uniformity of the primary particle is also very good.The primary particle can be made smaller and the particle is more inclined to spherical morphology, which is beneficial to reduce the lithium intercalation dynamics characteristics of the material in the charging and discharging process, and thus improve the first coulomb efficiency of the material.
