High impedance at the contact points between solid electrolytes and electrode active materials limits power density. Reducing this resistance ensures efficient ion transport and prevents localized degradation during cycling.

Low intrinsic electronic conductivity in olivine-structured phosphates limits high-rate performance. Reducing internal resistance through optimized conductive networks prevents power density loss and thermal instability.

Poor connectivity between lithium supplement materials and the electrode matrix limits electrochemical capacity. Improving this interface reduces internal resistance and prevents premature capacity loss in high-energy density cells.
