Microbatteries: Self‐Supported 3D Array Electrodes for Sodium Microbatteries (Adv. Funct. Mater. 3/2018)

Miniaturized on-chip high power microbatteries are extremely desirable for autonomous microelectronics but require a challenging three-dimensional (3D) battery design. In article number 1704880, Jianfeng Ni and Liang Li summarize the state-of-the-art progress in the design and application of 3D arrays for sodium microbatteries, and highlight the importance of integrating novel concepts into 3D electrode fabrication, characterization, and modeling to meet practical requirements.
