💡 Novelty & Significance:
PDVS enables cross-phase regulation in Ni-rich pouch cells by synchronously scavenging HF/H₂O and forming Si-containing interphases on both electrodes. This dual action suppresses coupled impurity–interphase degradation and cross-talk under thermal stress, delivering 92.81% retention after 304 cycles at 45°C and reduced swelling at 60°C. It offers a manufacturing-compatible electrolyte design principle for thermally durable Ni-rich batteries.
