Abstract
with a capacity retention of 95.5% after 2100 cycles. This study not only provides a novel approach for synthesizing nanoscale vanadate cathodes with rich oxygen vacancies, but also proposes the "expansion counteraction effect" theory, offering innovative insights into the design of high cycling stability cathodes for AZIBs.
