“…The reason is not clear. However, Wu 58 and co-workers reported that during the reaction of the large size of sodium ions with the electrodes, more electrolyte penetrates from the surface of electrode into the bulk and then more active materials are participated into the reaction with the increasing of the cycling numbers; also, some other reported works 59,60 claim that the deposition of transition metal compounds on the anode electrode would induce the chemical degradation of SEI film. When the accumulation of produced metallic titanium reached to a certain amount, metallic titanium may catalyze and accelerate the decomposition of SEI film with the electrolyte, which could cause a sudden rise of specific capacity of electrodes.…”

Sodium ion batteries are considered as one of the most promising energy storage devices as lithium ion batteries due to the natural abundance of sodium. tio 2 is very popular as anode materials for both lithium and sodium ion batteries because of the nontoxicity, safety and great stabilities. However, the low electronic conductivities and inferior sodium ion diffusion make it becoming a great challenge to develop advanced tio 2 anodes. Doping heteroatoms and incorporation of defects are believed to be great ways to improve the electrochemical performance of tio 2 anodes. In this work, commercial tio 2 (P25) nanoparticles was modified by hydrogen and nitrogen high-power plasma resulting in a disordered surface layer formation and nitrogen doping as well. the electrochemical performances of the samples as anode materials for sodium ion batteries was measured and the results indicated that after the hydrogen-nitrogen plasma treatment, H-N-TiO 2 electrode shows a 43.5% of capacity higher than the P-TiO 2 after 400 cycles long-term discharge/charge process, and the samples show a good long cycling stability as well, the Coulombic efficiencies of all samples are nearly 99% after 50 cycles which could be sustained to the end of long cycling. in addition, hydrogen-nitrogen plasma treated tio 2 electrode reached the stable high Coulombic efficiency earlier than the pristine material. High resolution teM images and XpS results indicate that there is a disordered surface layer formed after the plasma treatment, by which defects (oxygen vacancies) and N-doping are also introduced into the crystalline structure. All these contribute to the enhancement of the electrochemical performance. Rechargeable sodium ion batteries (SIBs) have been considered as the competitive alternative to lithium ion batteries because of some special merits, such as environment friendly, low cost and especially abundant alkali element widely distributed on earth 1-3. However, there is a big challenge that the ion radius of Na ions are ~ 70% larger than that of Li ions, so finding proper electrode materials which could provide big interstitial space to accommodate sodium ions and allow reversible and rapid ion insertion/extraction 3 is a challenging topic at the moment. Recently, many efforts have been made to explore advanced anode materials for sodium ion batteries. Firstly, carbonaceous material is an important choice which is very cheap however carbonaceous materials show undesired properties with low capacities and/or poor cycle performance 4. Secondly, Ti-based materials is a promising anode materials for sodium ion batteries, including Na 2 Ti 3 O 7 , Na 0.66 [Li 0.22 Ti 0.78 ]O 2 , Li 4 Ti 5 O 12 , and titanium dioxide (TiO 2) 5. Moreover, other materials based on alloying reactions (such as Sn, Sb, P and their compounds e.g. inter-metallics, oxides, sulfides, and phosphides) 6-10 and conversion reactions (oxides and sulfides, e.g. Fe 2 O 3 ,

“…These effects eventually lead to increased cell impedance, more side reactions, and finally to reduced life [16, 20, 21]. Therefore, it is important to prevent the dissolution of TMs in LIBs, their migration to the anode, or to enhance the tolerance of LIBs regarding the dissolved TMs [22–27].…”

Mn 2+ or Mn 3+ ? Investigating transition metal dissolution of manganese species in lithium ion battery electrolytes by capillary electrophoresisA new CE method with ultraviolet-visible detection was developed in this study to investigate manganese dissolution in lithium ion battery electrolytes. The aqueous running buffer based on diphosphate showed excellent stabilization of labile Mn 3+ , even under electrophoretic conditions. The method was optimized regarding the concentration of diphosphate and modifier to obtain suitable signals for quantification. Additionally, the finally obtained method was applied on carbonate-based electrolytes samples. Dissolution experiments of the cathode material LiNi 0.5 Mn 1.5 O 4 (lithium nickel manganese oxide [LNMO]) in aqueous diphosphate buffer at defined pH were performed to investigate the effect of a transition metal-ion-scavenger on the oxidation state of dissolved manganese. Quantification of both Mn species revealed the formation of mainly Mn 3+ , which can be attributed to a comproportionation reaction of dissolved and complexed Mn 2+ with Mn 4+ at the surface of the LNMO structure. It was also shown that the formation of Mn 3+ increased with lower pH. In contrast, dissolution experiments of LNMO in carbonate-based electrolytes containing LIPF 6 showed only dissolution of Mn 2+ .Abbreviations: LIBs, lithium ion batteries; LMO, lithium manganese oxide; LNMO, lithium nickel manganese oxide; SEI, solid electrolyte interphase; TM, transition metal; XANES, Xray absorption near-edge structure spectroscopy Color online: See the article online to view Figs. 1-5 in color.

Poor cycle performance is the critical challenge for commercialization application of layered LiNi x Co y Mn z O 2 (x + y + z = 1) cathode materials. Herein, the optimized LiNi 0.493 Co 0.214 Mn 0.293 O 2 (Al-LNCM) is modified by Al 3+ doping and passivation-film coating via the previous cycles using aluminum bis(oxalato)borate (Al(BOB) 3 )-based electrolyte. Results show that the electrochemical performance of Al-LNCM is significantly improved after dual modification, especially for the cycling and rate performances. On one hand, Al 3+ doping maintains the layered structure stability and suppresses the degree of Li + /Ni 2+ cation mixing, thereby inhibiting structural degradation and facilitating the transport of Li + ions. On the other hand, the prior formation of the Al-and Bcontaining surface coating can block the direct contact between the electrode and the electrolyte, which inhibits excessive electrolyte decomposition and undesirable interface side reactions.
