Scalable Upcycling of Spent Lithium‐Ion Battery Anodic Graphite to Electronic‐Grade Graphene

Advanced Science, EarlyView.
Graphite anodes from spent lithium‐ion batteries are upcycled into electronic‐grade graphene nanoplatelets for highly conductive screen printing inks (> 104 S m−1). Screen‐printed micro‐supercapacitors confirm the utility of the upcycled graphene (1.78 mF/cm2 capacitance for > 10 000 cycles). Life cycle assessment and techno‐economic analysis highlight

Interface Construction via Scavenging Oxygen Species Enables High‐Performance Li‐Rich Layered Oxide Cathode

Advanced Science, EarlyView.
To inhibit electrolyte decomposition by nucleophilic attack in carbonate electrolyte, LiBOB and LiDFOP with strong oxygen scavenging ability are selected to quench reactive oxygen species and following construct a robust CEI film on the LRLO cathode. The electrochemical performance of the LRLO cathode is largely improved, attributed to decomposition ...

Lithium Metal Anodes with Nonaqueous Electrolytes

Chemical Reviews, 2020
High-energy rechargeable lithium (Li) metal batteries (LMBs) with Li metal anode (LMA) were first developed in the 1970s, but their practical applications have been hindered by the safety and low-efficiency concerns related to LMA. Recently, a worldwide effort on LMA-based rechargeable LMBs has been revived to replace graphite-based, Li-ion batteries ...

Lithium Metal Anode

2021
Deposition and dissolution of lithium metal have been investigated in an equimolar mixture of lithium bis(trifluoromethylsulfonyl)amide (LiTFSA) and glyme [triglyme (G3) or tetraglyme (G4)] solvate ionic liquid. The limiting current for deposition of lithium was not observed probably because of the high concentration of lithium species and a decrease ...
