Abstract

Various three-dimensional battery structures are disclosed, in certain embodiments comprising a battery enclosure and a first plurality of electrodes within the enclosure. The first plurality of electrodes includes a plurality of cathodes and a plurality of anodes. The first plurality of electrodes includes a second plurality of electrodes selected from the first plurality of electrodes. The three-dimensional battery includes a first structural layer within the battery enclosure. Each of the second plurality of electrodes protrudes from the first structural layer. The three-dimensional battery includes a plurality of electrical current-reducing devices within the enclosure. Each of the second plurality of electrodes is coupled to one of the plurality of current-reducing devices.
