Back Cover: Three-dimensionally ordered macroporous (3DOM) nitroxide polymer brush electrodes for organic radical batteries are fabricated. The electrodes prevent the nitroxide polymer from dissolving into electrolytes and significantly improve the cycle-life performance of batteries. The discharge capacity of the 3DOM electrodes is about 40 times higher than that of the planar electrode. Further details can be found in the article by C.-H. Lin, W.-J. Chou, and J.-T. Lee* on page 107.
