New 3D-printed battery electrodes double storage capacity across 7,500 charge cycles

LLNL researchers used 3D printing and computational design to build interlocking battery electrodes.

The architecture cuts ion-trapping dead zones, nearly doubling storage capacity without slowing charging.

The cells also showed strong durability, lasting more than 7,500 cycles.

If it scales, the design could help improve batteries for EVs, consumer devices, and grid storage.
