The increase in the use of electric vehicles (EVs) will ultimately lead to an increase in the number of end-of-life lithium-ion batteries (LIBs) that need to be recycled. A particular challenge concerns how to deal with low value cathodes, such as LiMn2O4 (LMO).
...The pursuit of low-carbon transport has significantly increased demand for lithium-ion batteries. However, the rapid increase in battery manufacturing, without adequate consideration of the carbon emissions associated with their production and material demands, poses the threat of shifting the bulk of emissions upstream. In this article, a life cycle assessment (LCA) model is developed to...
Lithium-ion battery anodes were produced and tested using gelatin and sodium alginate (NaAlg) biopolymers, modified with a deep eutectic solvent (DES). Anodes created with these alternative binder systems showed comparable capacities and Coulombic efficiencies to cells assembled using commercial PVDF and CMC/SBR binders. Rate tests of these cells found that DES-NaAlg possessed a higher rate...
With the growing interest in niobium-based anodes for high-power lithium-ion batteries (LIBs), current chemistries (for this application) such as Li4Ti5O12 (LTO) anodes will be superseded, and as such an efficient and effective method of recycling needs to be considered. With this motivation, a potential upcycling route is proposed for LTO for the first time, such...
This investigation shows the effect of blending sodium alginate (NaAlg) and a conducting polymer, polyaniline (PANI), in lithium-ion battery (LIB) anodes. We demonstrate here that inclusion of the PANI into the binder improves the connectivity of the composite, resulting in better performance. Additionally, the blends are easily formulated without sophisticated methods or additional equipment.
