New Energy Battery Attenuation Recovery

What causes battery performance attenuation?

Generally, most anodes of commercial LIBs are graphite-based materials. The continuous growth of the SEI film on the graphite surface is the main cause of battery performance attenuation. Even worse, the volume of graphite undergoes a 10% change during the charging and discharging process.

Can battery recycling boost energy utilization?

As far as environmental governance and resource utilization are concerned, the recovery and recycling of expired LIBs are not only turning waste into treasure, but also a potential boost for new energy utilization. In the future, battery recycling is bound to become an important goal for countries to tap new energy opportunities.

How to recover valuable metals from spent lithium-ion batteries?

Xiao, S.W., Ren, G.X., Xie, M.Q., et al.: Recovery of valuable metals from spent lithium-ion batteries by smelting reduction process based on MnO-SiO 2 -Al 2 O 3 slag system. J. Sustain.

How to improve the reusability of used batteries?

Overall, the simplification of SLIBs management systems, the promotion of automated processing, and the prioritization of economical recycling technologies will continue to promote the nirvana rebirth of used batteries and maximize the reusability of LIBs and their ancillary products. Jia-Lin Yang made conceptualization and wrote original draft.

Can resource recovery technology improve the dismantling process of retired lithium batteries?

This study focuses on optimizing resource recovery technology in the dismantling process of retired lithium batteries to mitigate environmental pollution.

How can retired batteries improve environmental performance?

Although retired batteries have a relatively low round-trip efficiency, their secondary use can be improved in overall environmental performance by increasing the service period of retired LIBs and switching to clean energy, such as nuclear energy .
