“…Iodine-doped graphene can also be prepared by annealing am ixture of graphite oxide (GO) and iodine at the high temperature of 950 8 8C. This anode exhibited ahigh reversible capacity of above 1500 mAh g À1 over 200 cycles.T he significantly improved electrochemical performance compared to that of the bare graphene was attributed to the formation of I 3 À and I 5 À species,d efects,a nd an optimized microstructure, [132] although the iodine content of 0.06 at %inthe anode was very low.I na ddition, Chang et al found that iodinedoped red phosphorus nanoparticles (RPNPs), which were prepared by reacting PI 3 with ethylene glycol in the presence of cetyltrimethylammonium bromide (Figure 7), had ah igh electrical conductivity of up to 1.81 10 À2 Sm À1 .T his value is close to that of the semiconductor germanium (1.02 10 À2 Sm À1 )a nd 10 10 orders higher than that of commercial red phosphorus.C onsequently,a ne xcellent electrochemical performance was obtained for the RPNP electrode,w ith ar eversible capacity of about 1562 mAh g À1 after 150 cycles, [133] even though the carbon composite strategy was not employed. Thef act that iodine doping can bring about remarkable improvements in the microstructures of the asprepared materials is inspiring.H owever,m ore analysis concerning the electronic and chemical states,e lectrochemical impedance,a nd the bulk and interface structure of the electrodes during discharge and charge is needed to clarify the exact functions of iodine species in the electrodes.…”

Rechargeable batteries are considered one of the most effective energy storage technologies to bridge the production and consumption of renewable energy. The further development of rechargeable batteries with characteristics such as high energy density, low cost, safety, and a long cycle life is required to meet the ever‐increasing energy‐storage demands. This Review highlights the progress achieved with halide‐based materials in rechargeable batteries, including the use of halide electrodes, bulk and/or surface halogen‐doping of electrodes, electrolyte design, and additives that enable fast ion shuttling and stable electrode/electrolyte interfaces, as well as realization of new battery chemistry. Battery chemistry based on monovalent cation, multivalent cation, anion, and dual‐ion transfer is covered. This Review aims to promote the understanding of halide‐based materials to stimulate further research and development in the area of high‐performance rechargeable batteries. It also offers a perspective on the exploration of new materials and systems for electrochemical energy storage.

“…46,[51][52][53] There have been several studies on modifying graphite surfaces such as heat and acid treatment to control surface chemistry (e.g., oxygen and nitrogen). [54][55][56][57][58] Nitrogen or oxygen on graphite surfaces can interact more with Li + in electrolyte because their electron density is high. Heat treatment in an inert environment can reduce oxygen from the graphite surface.…”

Reducing cost and increasing energy density are two barriers for widespread application of lithium-ion batteries in electric vehicles. Although the cost of electric vehicle batteries has been reduced by $70% from 2008 to 2015, the current battery pack cost ($268/kWh in 2015) is still >2 times what the USABC targets ($125/kWh). Even though many advancements in cell chemistry have been realized since the lithium-ion battery was first commercialized in 1991, few major breakthroughs have occurred in the past decade. Therefore, future cost reduction will rely on cell manufacturing and broader market acceptance. This article discusses three major aspects for cost reduction: (1) quality control to minimize scrap rate in cell manufacturing; (2) novel electrode processing and engineering to reduce processing cost and increase energy density and throughputs; and (3) material development and optimization for lithium-ion batteries with high-energy density. Insights on increasing energy and power densities of lithium-ion batteries are also addressed.

“…14 Effects of other surface treatments on SEI formation have also been reported. [15][16][17][18] Increasing hydrophilicity of hydrophobic graphite improves electrolyte wetting, especially in small pores. 19 In the polymer industry, carbon nanotubes have been used as strength-enhancing materials in polymer structures, 20 but the carbon nanotubes do not disperse well in the polymer matrix because their surfaces are hydrophobic like graphite.…”

Effects of ultraviolet (UV) light on dried graphite anodes were investigated in terms of the cycle life of lithium ion batteries. The time variations for the UV treatment were 0 (no treatment), 20, 40, and 60 minutes. UV-light-treated graphite anodes were assembled for cycle life tests in pouch cells with pristine Li 1.02 Ni 0.50 Mn 0.29 Co 0.19 O 2 (NMC 532) cathodes. UV treatment for 40 minutes resulted in the highest capacity retention and the lowest resistance after the cycle life testing. X-ray photoelectron spectroscopy (XPS) and contact angle measurements on the graphite anodes showed changes in surface chemistry and wetting after the UV treatment. XPS also showed increases in solvent products and decreases in salt products on the SEI surface when UV-treated anodes were used. The thickness of the surface films and their compositions on the anodes and cathodes were also estimated using survey scans and snapshots from XPS depth profiles.
