Smart energy storage has revolutionized portable electronics and electrical vehicles. The current smart energy storage devices have penetrated into flexible electronic markets at an unprecedented rate. Flexible batteries are key power sources to enable vast flexible devices, which put forward additional requirements, such as bendable, twistable, stretchable, and ultrathin, to adapt mechanical deformation under the working conditions. This review summarizes the recent advances in construction and configuration of flexible batteries and discusses the general metrics to benchmark various flexible batteries with different materials and chemistries. Moreover, we present advanced prototype flexible batteries developed by some companies to afford general envision of the technological status. Lastly, the critical points are summarized in the development of flexible batteries and remaining challenges are also presented for the future design of flexible batteries in practical perspectives.

“…With the rapid advancement of flexible electronic devices, such as electronic skin and flexible screens, and so on, the development of high-performance flexible energy storage technologies has become a hot topic in the current research field [1][2][3][4][5][6][7][8]. At present, lithium ion batteries (LIBs), known for their low cost, long cycle life, and high energy density, are still the most widely used and mature among the many energy storage systems [3,[9][10][11][12][13][14][15][16][17][18].…”

“…In addition, their stable structure, especially nickel silicate, can also accommodate the volume change caused by the electrochemical charging and discharging process to a certain extent. These advantages make nickel silicate an ideal material for the storage of alkaline metal ions, including Li + ion and Na + ion [4]. However, the small number of redox couples and poor conductivity of conventional silicate materials usually limit their capability to store Li ion at high capacities or high rates [34,35].…”

Lithium-ion batteries are promising energy storage devices used in several sectors, such as transportation, electronic devices, energy, and industry. The anode is one of the main components of a lithium-ion battery that plays a vital role in the cycle and electrochemical performance of a lithium-ion battery, depending on the active material. Recently, SiO 2 has garnered attention for use as an anode in lithium-ion batteries. SiO 2 has a high specific capacity, good cycle stability, abundance, and low-cost processing. However, the high expansion and shrinkage of the SiO 2 volume during lithiation/delithiation, low conductivity, and solid electrolyte interphase formation resulted in damage to the electrode structure and caused a decrease in SiO 2 performance as an anode for a lithium-ion battery. The modified properties of SiO 2 and the use of carbon materials as composites of SiO 2 are effective strategies to overcome these problems. This review focuses on analyzing the role of various carbon materials in composite SiO 2 /C to enhance the performance of SiO 2 materials.
