Given the rising lithium-ion battery retirement trend, there is a pressing need for a sustainable, cost-effective, versatile, and industrially viable positive active powder reprocessing method. The current treatment methods require significant amounts of acids, reducing agents, and other additives, resulting in increased treatment expenses and detrimental environmental consequences. This paper proposes a synergistic redox strategy, based on thermodynamic calculations of potential self-promoting reactions in mixed LFP/NCM systems, for the recovery of spent LFP and NCM batteries without the need for additional agents in a milder acidic atmosphere. In this cooperative redox strategy, the spontaneous extraction and oxidation of Fe2+ to Fe3+ took place within the acidic solution atmosphere encapsulating LFP. Simultaneously, NCM underwent further reduction, yielding Ni2+ and Fe2+, thereby enabling the proficient dissolution and segregation of lithium and transition metal ions. The leaching rate of lithium, nickel, cobalt and manganese was close to 100% when the reaction was carried out at 20 °C for 40 min. The final raw material was reprepared into a battery with a capacity of 168.8 mA h g−1 at 1C, and the cycle retention rate was 76.78% after 300 cycles. Regenerating FPO into LFP cathode material achieves closed-loop recycling of all elements and generates 12% higher profits compared to separate processes. Our method proposes a zero-additive battery recycling process and successfully explains the intrinsic redox process. [ABSTRACT FROM AUTHOR]

[Objective] The aim was to explore the relation between culture diversity and biodiversity of the Zhuang people. [Method] Botany in minority ethnic groups was researched based on information searching, interviewing and surveying with consideration of the importance of cultural and biological diversity. [Result] The Zhuang culture, involving color, cuisine, geography and song, is closely related to biodiversity, and worship culture, involving plants, animals, and folk custom, plays an important role in protection of biodiversity. However, biodiversity is significantly affected by some factors, including natural condition, population quality, traditional culture, wrong policies, negative effect of modern ecological culture, natural and environmental resources. [Conclusion] It is suggested that local education should be enhanced to absorb modern science&technology, to promote the concept of confirming to nature and of harmonious development and to achieve sustainable development in western of Guangxi.
