Toward Circular Energy: Exploring Direct Regeneration for Lithium‐Ion Battery Sustainability

Advanced Materials, Год журнала: 2024, Номер 36(32)

Опубликована: Май 25, 2024

Lithium-ion batteries (LIBs) are rapidly developing into attractive energy storage technologies. As LIBs gradually enter retirement, their sustainability is starting to come focus. The utilization of recycled spent as raw materials for battery manufacturing imperative resource and environmental sustainability. depends on the recycling process, whereby cycling must be maximized while minimizing waste emissions consumption. Although LIB technologies (hydrometallurgy pyrometallurgy) have been commercialized a large scale, they unavoidable limitations. They incompatible with circular economy principles because require toxic chemicals, emit hazardous substances, consume amounts energy. direct regeneration degraded electrode from viable alternative traditional nondestructive repair technology. Furthermore, offers advantages such maximization value materials, use sustainable, nontoxic reagents, high potential profitability, significant application potential. Therefore, this review aims investigate state-of-the-art that can extended large-scale applications.

Electrolyte chemistry towards ultra‐high voltage (4.7 V) and ultra‐wide temperature (−30 to 70 °C) LiCoO2 batteries

Angewandte Chemie International Edition, Год журнала: 2025, Номер unknown

Опубликована: Янв. 7, 2025

LiCoO2 batteries for 3 C electronics demand high charging voltage and wide operating temperature range, which are virtually impossible existing electrolytes due to aggravated interfacial parasitic reactions sluggish kinetics. Herein, we report an electrolyte design strategy based on a partially fluorinated ester solvent (i.e., DFEA) that achieves balance between weak Li+-solvent interactions, sufficient salt dissociation, stability, superior thermal stability address the aforementioned challenges. The resulting high-voltage wide-temperature (HWE) not only possesses low desolvation energy, fast Li+ transport, oxidation excellent thermal-abuse tolerance non-flammability, but also enables formation of both inorganic-rich cathode interphase (CEI) solid (SEI). Owing above merits, this HWE endows highly stable operation cathodes under ultra-high 4.7 V Graphite || in ultra-wide range -30 70 °C. Meanwhile, 1.7 Ah-level 4.6 pouch cell with energy density 240 Wh kg-1 delivers cycling representing significant advancement towards batteries.
