Generated Pattern Current for Electrochemical Cell Formation: Interface Layer-Controlled Initial Activation via Dynamic Defined Pattern Charging

Key Points

• This research aims to improve battery formation processes using a GPC-based protocol.
• Utilized Generated Pattern Current (GPC) for battery formation.
• Structured Solid Electrolyte Interphase (SEI) growth into distinct phases: nucleation, consolidation, stabilization.
• Compared the efficiency and formation time to conventional Constant Current (CC) protocols.
• Formation time was reduced by 50-70% compared to CC protocols.
• Improved SEI growth structure was achieved during the process.
