Metal batteries with high theoretical capacities have become more important than ever in pursuing carbon-neutral initiatives to reduce fossil energy consumption and incorporate intermittent renewable energy into the electric grid. However, cathode materials often encounter significant challenges, such as sluggish reaction kinetics, limited capacities, or low operation voltages, limiting the practical applications of these batteries. Inspired by light− matter interactions that might provoke a photoelectric or photothermal effect on lightresponsive materials, various light-responsive batteries have been developed by introducing photoactive materials to convert solar energy into electrical (or thermal) energy, addressing the issues facing cathode materials. Despite the fact that some reviews have been published to summarize the advances in light-responsive batteries with the rapid development of the rising field, the basic working principles of light-responsive batteries are still not well elucidated in detail. In this review, we first give a summary of the understanding of the photoelectric and photothermal effects and correlate their parameters with the metrics (voltage, capacity, and kinetics) of light-responsive batteries. Then, we provide representative examples of light-responsive batteries to support the understanding. Finally, the challenges in the development of light-responsive metal batteries are discussed. Accordingly, potential directions and key perspectives for light-responsive metal batteries are also proposed in the hope of guiding their design and optimization for accelerating practical application.

The poor interfacial stability not only deteriorates fibre lithium-ion batteries (FLBs) performance but also impacts their scalable applications. To efficiently address these challenges, Prof. Huisheng Peng team proposed a generalized channel structures strategy with optimized in situ polymerization technology in their recent study. The resultant FLBs can be woven into different-sized powering textiles, providing a high energy density output of 128 Wh kg-1 and simultaneously demonstrating good durability even under harsh conditions. Such a promising strategy expands the horizon in developing FLB with particular polymer gel electrolytes, and significantly ever-deepening understanding of the scaled wearable energy textile system toward a sustainable future.

The composite gel electrolyte (CGE), which combines the advantages of inorganic solid‐state electrolytes and solid polymer electrolytes, is regarded as the ultimate candidate for constructing batteries with high safety and superior electrode‐electrolyte interface contact. However, the ubiquitous agglomeration of nanofillers results in low filler utilization, which seriously reduces structural uniformity and ion transport efficiency, thus restricting the development of consistent and durable batteries. Herein, a solution‐processable method to in situ construct CGE with high filler utilization is introduced. The homogeneous metal–organic framework fillers contribute to uniform ionic and electronic filed distribution, realizing a stable electrode‐electrolyte interface. Consequently, the CGE with high filler utilization achieves an ultra‐long lifespan of 10 000 cycles with a capacity retention of 80.2%. This work provides guidance for constructing high‐performance CGEs in electrochemical energy‐storage devices.
