Summary: Organic radical batteries (ORBs) with radical-branched polymers as cathode materials are considered as a promising solution for energy storage. A chemically stable polynitrosoarene (tris(4-nitrosophenyl)amine) is designed as an efficient cathode for ORBs, which exhibits remarkable reversible charge/discharge capability and high capacity. It can achieve a capacity of up to 300 mA h g(-1) (93% theoretical capacity) after 100 cycles at 100 mA g(-1) within a wide potential window. The material also shows outstanding cycle life with 85% capacity retention after 1000 cycles at 1000 mA g(-1), making it the best-reported organic radical cathode material for lithium-ion batteries.

Summary: High-energy lithium-ion batteries with silicon-based anode materials have short cycle lives due to mechanical failure at the anode level and irreversible consumption of cathode Li during initial charge. Previous strategies for (electro)chemical prelithiation have safety concerns and are less compatible with industrial battery manufacture. A new concept of prelithiation using lithiation agents supported functional separator is shown to replenish cathode Li loss and inhibit local over-lithiation and dendrite formation, resulting in improved cycling performance of the battery.

Summary: This study conducted comprehensive research on the microstructural evolution of degraded LiNi1-x-yCoxMnyO2 electrodes to propose a targeted method for recycling spent cathode materials based on increased residual lithium compounds. The separation process using only water eliminates the need for toxic organic solvents, complicated processes, and waste treatment, making it an environmentally friendly and efficient recycling strategy. The satisfactory capacity recovery of the cathode through simple sintering provides a sustainable closed-loop for spent cathodes and offers new inspiration for the design of lithium-ion battery recycling.
