Abstract High‐voltage (≥4.5 V) Ni‐rich cathodes can help advance the development of next generation high‐energy lithium‐ion batteries. However, high voltage used in deteriorates cycling performance due to structural disintegration polycrystalline particles and electrolyte decomposition. Herein, a robust protective layer with high‐voltage tolerance is applied surface address these challenges. The consists crosslinked bio‐based elastomer (CBE) whose main chain connected by saturated bonds, which confers tolerance. CBE an elastic material viscoelastic properties, allowing it serve as energy dissipation that mitigates strain accumulation preserves integrity coated cathode. also shows polarity rapid transport capabilities presence oxygen‐containing components, ensures tight wrapping improves their interfacial reaction kinetics. As anticipated, 4.5 V Li||LiNi 0.6 Co 0.2 Mn O 2 batteries exhibit initial capacity 176.7 mA h g −1 retention rate 79.5% after 400 cycles. This study underscores critical role customized stabilizing at voltages.
