“…Two types of vanadium oxides (V 2 O 3 and V 2 O 5 ) are investigated for LIB and SIB applications; the former is treated as of conversion‐type, and its capacity in SIB systems is much smaller than in LIBs due to the negative voltage shift of 0.96 V between the two systems. [ 229,230 ] V 2 O 5 , on the contrary, was usually used as a cathode material based on intercalation mechanisms, thought the conversion reaction 0.1V 2 O 5 + Na → 0.5Na 2 O + 0.2V is thermodynamically possible (reaction enthalpy: −0.57 eV). [ 231,232 ] Above 1.2 V vs Na + /Na, V 2 O 5 would turn into mixture of NaV 2 O 5 and Na 2 V 2 O 5 upon sodium insertion, with the specific capacity less than 295 mAh g −1 (the theoretical value based on Na 2 V 2 O 5 ), and the crystalline structure could be recovered upon the sodium extraction.…”

type is cheap but with a rather low energy density and cannot survive many cycles; the latter type has higher energy density and longer cycle life, but is more expensive. [3] Both those secondary batteries suffer from the memory effect, and their use is under serious environmental concerns due to the involvement of the toxic lead and cadmium. [3] Nickel-metal hydride (Ni-MH) batteries can deliver higher energy capacity (the amount of stored energy in per unit mass, usually measured in Wh kg -1 ) and are more environmentally friendly, and from these reasons they used to dominate the market for electrical tools and EV. [4] At present, however, the share of Ni-MH batteries is shrinking, as we have another choice with a much higher energy density, namely lithium ion batteries (LIBs). The energy density of Ni-MH batteries is 60-70 Wh kg -1 , and that of LIBs was about 110 Wh kg -1 when they were commercially launched. [5] In the last decade, the price of LIBs decreased by ≈80% (now reaching <$200 kWh -1 ), and their energy density has been significantly improved (>200 Wh kg -1 ). [6] Other advantages of LIBs include long cycle life, low self-discharge, and absence of the memory effect. Thus far, being cost-effective and performance-competitive, LIBs have conquered the market for various important applications such as mobile phones, portable electronics, and EV.Beyond the state-of-the-art LIBs, efforts of battery researchers are going into following directions. The energy density of gasoline is about 13 kWh kg -1 , a value LIBs would never get close to. [7] It is normal to have "range anxiety" in the transition from petrol vehicles to EV. To eliminate such anxiety and make LIBs more competitive, intensive efforts are being placed into the research of high-capacity electrode materials for LIBs (such as silicon and lithium metal anode) and other battery systems (e.g., lithium-sulfur, lithium-air, and zinc-air batteries). [8] Another important direction is the development of safer batteries, such as aqueous and all-solid-state batteries, as safety concerns on LIBs are mainly related to the use of flammable electrolytes. [9,10] At the same time, the demand for LIBs worldwide is still increasing, and the production of the LIBs is growing rapidly, while the important constituting elements of those batteries, especially lithium and cobalt, are limited in supply. [5] Even though the availability of lithium at the present time may not be the major problem, and the recycling of used LIBs is under consideration, the world is faced with the potential risks in supply chains, as the annual global lithium production has already surpassed 0.085 million tons in 2018, while the total lithium reserve is estimated to be ≈14 million The increase in electricity generation poses growing demands on energy storage systems, thus offering a chance for the success of the reliable and cost-effective energy storage technologies. Sodium ion batteries are emerging as such a technology, which is however not yet mature enough to enter the market. At th...

“…Recently, transition metal oxides have been regarded as advanced alternatives owing to their higher theoretical capacity (>700 mA h g −1 ), natural abundance and low cost, such as Fe 2 O 3 , Co 3 O 4 , MnO, etc. Among these anode material candidates, V 2 O 3 has become a promising anode material for LIBs owing to the merits of higher specific capacity (1070 mA h g −1 ), multi‐oxidation states and low toxicity ,. However, dramatic volume variation during lithiation and delithiation process and low electrical conductivity prohibit its practical utilization in LIBs.…”

The potential applications of V2O3 in lithium ion batteries (LIBs) are significantly hampered by the comparatively poor rate performance as well as fast capacity decay due to the low electrical conductivity and huge volume change during cycling process. Various strategies have been proposed to address these drawbacks. Among different methods, reducing their particle size to the nanometer range and combining with carbonaceous matrix seem to be effective ways to improve electrochemical property. Herein, we prepared V2O3 nanorods in‐situ adhered to rGO via hydrothermal reaction and heat‐treatment. One dimensional V2O3 nanorods combined with rGO can effectively shorten Li+ ions and electrons transport path, improve electrical conductivity and alleviate volume change. The strong chemical interaction between them would remarkably accelerate charge transfer. These features endow V2O3/rGO composite with good cycling stability (675 mA h g−1 after 300 cycles at 500 mA g−1) and excellent rate performance (428 mA g h−1 at 2000 mA g−1). New prospects will be brought by this work for the potential application of V2O3 based material as advanced anode material for LIBs.

“…Furthermore, we found that the property of the CV-600 electrode is much better than some V 2 O 3 /C composites reported in the open literature 17,39,36,37,40,41 as shown in Table S1. Obviously, the most important distinctiveness of the CV-600 composite has a unique peapod-like structure.…”

Peapod-like CNT@V 2 O 3 (CNT = carbon nanotube) with small V 2 O 3 nanoparticles (13 nm) and a good electronic conductive network (the CNTs) was constructed through a reflux and annealing process. As anode materials, CNT@V 2 O 3 shows admirable capacity (652.4 mA h g −1 at 500 mA g −1 for 200 cycles), a long lifespan, and good rate performance. Compared with V 2 O 3 , the peapod-like CNT@ V 2 O 3 composites have superior electrochemical performance due to the porous structure, the V 2 O 3 particles, and peapodlike architecture, which reduce the transmission distance of lithium ion, enlarge the superficial area, and enhance structural stability. As a result, the unique composite material with a peapod-like structure is an ideal anode material.
