Researchers from Lawrence Livermore National Laboratory (LLNL) have developed a 3D-printed electrode design for electrochemical energy storage (EES) devices such as rechargeable batteries and supercapacitors.
It solves the conflict between high capacity (storing a lot of energy) and high power (releasing it quickly) in storage devices.
The development opted for an optimized, interlocking 3D design to eliminate”dead zones” where ions are typically trapped. This new architecture doubles storage capacity without impacting the charging speed or reliability required for applications such as electric vehicles and grid storage.
