However, molecular design remains largely empirical because a unified physical model linking electronic structure with reduction dynamics is lacking. Here, we establish a molecular charge-topology framework that identifies intramolecular charge distribution as a key determinant of electrochemical stability. Two descriptors, charge asymmetry degree (CAD) and balance of charges (BOC), correlate with electron affinity and reorganization energy, respectively, thereby connecting reduction thermodynamics and kinetics. Guided by this framework, a molecular charge-topology electrolyte enables Li||Cu cycling for over 5,600 h with an average Coulombic efficiency above 99.5%. Under ultra-lean conditions (electrolyte-to-capacity [E/C] = 0.75 g Ah−1), 13.0 Ah NCM955||Li pouch cells deliver over 630 Wh kg−1, while 5.0 Ah anode-free cells sustain cycling at a 5 A discharge rate.

This study addresses these issues by developing a synergistic, cascaded NiOx architecture via a robust dual-step chemical-bath deposition strategy. By identifying the rubidium ion (Rb+) as an optimal dopant, we construct a favorable interfacial energetic alignment that promotes hole extraction and reduces interfacial recombination. Beyond its electronic benefits, this cascaded HTL acts as a versatile template to regulate subsequent perovskite crystallization, facilitating strain-relaxed growth of the perovskite and suppressing non-radiative recombination at the buried interface. Consequently, small-area (0.09 cm2) PSCs achieve a high power conversion efficiency (PCE) of 27.05% (certified at 26.82%) with a fill factor of 86.96%. Industrial viability is demonstrated through 12.96 cm2 mini-modules yielding a 23.63% PCE. Furthermore, unencapsulated devices retain over 93% of their initial performance after 1,160 h of operation.
