The Strategy of Achieving Flexibility in Materials and Configuration of Flexible Lithium‐Ion Batteries

Abstract

In recent years, with the development of flexible intelligent wearable devices, flexible batteries have attracted widespread attention in energy storage systems. To satisfy the power supply as well as the integrity of flexibility for the flexible intelligent wearable devices, the development of batteries with both excellent electrochemical performance and wearable flexibility has attracted a lot attention. This review is focused on the discussion of how to realize battery flexibility from the perspective of flexible lithium‐ion batteries as one of the most ideal and promising flexible power sources. Also, the development of flexible lithium‐ion batteries in recent years and the methods to achieve the flexibility are reviewed from the aspects of battery materials and electrode structures, to provide new ideas for research about flexible lithium‐ion battery with a high energy density in the future.

Life Cycle Assessment of Energy Storage Technologies for New Power Systems under Dual‐Carbon Target: A Review

“…According to its energy conversion mechanism, ESTs can be divided into five categories: CES, ECES, MES, EES, and TES. [43][44][45][46][47][48][49] The classification of ESTs based on the energy conversion mechanism is illustrated in Figure 4.…”

Flexible aqueous supercapacitors with excellent cycling performance and high-energy density based on mesocrystalline NiCo-LDHs

“…3,4 During the past years, flexible lithium-ion batteries (LIBs) have been well developed as the potential energy resources of WEDs, but several cases of fires and explosions of LIBs have raised concerns about their safety, particularly for WEDs with the close contact of the human body. [5][6][7][8] Thereby, more efforts are being made to explore aqueous energy storage devices due to their better safety. 9,10 Among them, aqueous asymmetric supercapacitors (ASCs) are interesting due to their long life, high-power density, and good safety.…”

“…In recent years, flexible and wearable energy storage devices have acquired considerable attention. [1,2] Supercapacitors (SCs) are considered as ideal flexible electronics device candidates owing to high power density, long-term life, and fast charge/discharge rates. [3][4][5] As for electrode material, plentiful research efforts have been mainly devoted to the exploration of various carbonaceous materials including carbon black, carbon nanotubes, carbon nanofibers, and graphene.…”
