Stabilized Lithium Metal Powder (SLMP®) was applied in graphite anode and the effects of this prelithiation method to cell performance were investigated. Performance of prelithiated cells was compared with that of regular graphite based cells. The first cycle capacity loss of SLMP prelithiated cell was largely reduced and the corresponding first cycle Coulombic efficiency was significantly improved. The graphite/NMC cell with SLMP prelithiation but without any standard cell formation process showed better cycle performance than that of none SLMP containing cell with standard formation process. Prelithiation of graphite electrode with SLMP promote stable solid electrolyte interface (SEI) formation on the surface of graphite anode. Application of SLMP in lithium-ion battery thus provides an effective method to enhance capacity, and promises a low cost SEI formation process. This also implies the potential use of other promising anode materials, such as Si and Sn that have large first cycle capacity loss, in commercial lithium-ion batteries.

A simple solution processing method is developed to achieve a uniform and scalable stabilized lithium metal powder (SLMP) coating on a Li-ion negative electrode. A solvent and binder system for the SLMP coating is developed, including the selection of solvent, polymer binder, and optimization of polymer concentration. The optimized binder solution is a 1% concentration of polymer binder in xylene; a

Pure Sn nanoparticles electrode with Poly(9,9-dioctylfluorene-co-fluorenonecomethylbenzoic ester) (PFM) conductive binder are prepared and tested in sodium ion battery. It shows high specific capacity and high cycling stability without any conductive additive compared with Sn/CMC (carboxy methylated cellulose) and Sn/PVDF (polyvinylidene fluoride) electrode. The Sn in Sn/PFM electrodes delivers 806 mAh g -1 at C/50 and 610 mAh g -1 at C/10. After 10 cycles at C/10, the capacity of Sn has no decay.SEM and TEM images show that the Sn particles in Sn/PFM electrode are still fully coated by PFM polymer after huge expansion during sodiation and shrinkage during desodiation.

With the increased focus on sustainable energy, Li‐ion rechargeable batteries are playing more important roles in energy storage and utilization. Owing to their high safety, low cost, and moderate capacity, titanium dioxide (TiO2) nanomaterials have been considered as promising alternative anode materials for Li‐ion rechargeable batteries. Here, we present a concise overview of past research efforts on TiO2 nanomaterials as anode materials for Li‐ion rechargeable batteries. We focus on research examples that illustrate the importance of the nanometer‐scale, shape, dimensionality, and morphology of the TiO2 nanomaterials to their electrochemical properties for Li‐ion storage. Representative examples are given for nanoparticles, nanowires, nanotubes, nanosheets, and three‐dimensional materials, as well as amorphous structures. Approaches to improve the performance of TiO2 nanomaterials such as carbon coating, bulk doping, self‐structural modification, and compositing are surveyed briefly. Progress in the use of TiO2 nanomaterials in full‐cell configurations is also reviewed. Finally, the challenges for the practical applications of TiO2 nanomaterials in Li‐ion rechargeable batteries are discussed briefly.
