THREE-DIMENSIONAL POROUS CURRENT COLLECTOR WITH INTERNAL VOLUME FOR ACTIVE MATERIAL PARTICLES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18079945 titled 'THREE-DIMENSIONAL POROUS CURRENT COLLECTOR WITH INTERNAL VOLUME FOR ACTIVE MATERIAL PARTICLES

Simplified Explanation: The patent application describes an electrode for a rechargeable battery cell that includes a current collector with a 3D porous structure, active material particles, and a method of manufacturing the electrode.

  • The electrode has a current collector with a 3D porous structure that contains void spaces.
  • Active material particles are arranged within the void spaces of the current collector.
  • Charging the battery cell deposits ions onto the active material particles, expanding them into the void spaces.
  • Discharging the battery cell extracts the ions from the active material particles, causing them to contract out of the void spaces.

Key Features and Innovation:

  • Electrode with a current collector having a 3D porous structure.
  • Active material particles arranged within the void spaces of the current collector.
  • Reversible deposition and extraction of ions during charging and discharging processes.

Potential Applications:

  • Rechargeable batteries
  • Energy storage systems
  • Electric vehicles

Problems Solved:

  • Improved battery performance
  • Enhanced energy density
  • Longer battery cycle life

Benefits:

  • Higher energy efficiency
  • Increased battery capacity
  • Extended battery lifespan

Commercial Applications:

  • Optimized for use in electric vehicles
  • Energy storage solutions for renewable energy systems
  • Consumer electronics with longer battery life

Prior Art: Prior art related to this technology may include research on electrode materials for rechargeable batteries and methods of improving battery performance through structural design.

Frequently Updated Research: Ongoing research may focus on enhancing the 3D porous structure of the current collector, optimizing the arrangement of active material particles, and improving the manufacturing process for these electrodes.

Original Abstract Submitted

An electrode for a rechargeable battery cell includes an electrode substrate. The electrode also includes a current collector fixed to the electrode substrate and having a three-dimensional (3D) porous structure defining void spaces. The electrode additionally includes active material particles arranged within the void spaces. Charging the battery cell reversibly deposits transient ions onto the active material particles and expands the active material particles into the void spaces of the 3D porous structure and discharging the battery cell extracts the transient ions from the active material particles, such that the active material contracts out of the void spaces of the 3D porous structure. A method of manufacturing such an electrode for a rechargeable battery cell is also considered.
