Ten-degree energy storage gel battery

Can high-energy-density lithium batteries work stably in a wide-temperature gel polymer electrolyte?

We report a bioinspired gel polymer electrolyte that enables high-energy-density Li metal batteries to work stably in a wide temperature range from –30 to 80 °C. The wide-temperature gel polymer electrolyte is fabricated by using a branched polymer of which side chains are double coupled with their asymmetric analogues.

Are gel polymer electrolytes good for lithium-metal batteries?

As an intermediate state between liquid electrolytes and solid polymer electrolytes, gel polymer electrolytes (GPEs) are considered among the most promising electrolytes for lithium-metal batteries due to their high ionic conductivity, great flexibility, and favorable electrode-electrolyte interphases (EEIs) 5, 6, 7.

Are lithium ion batteries suitable for energy storage?

1. Introduction With the global implementation of carbon-neutral policies and the rapid growth of electric vehicles, secondary batteries, such as lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs), have emerged as key candidates for energy storage applications , , , .

Are flexible zinc-ion batteries suitable for wearable devices?

Flexible zinc-ion batteries (FZIBs) are ideal power sources for wearable devices, but their low volumetric energy densities have been a limitation for practical application. We present an ultrathin cellulose-based electrolyte (DCG) with a gradient hydropenic interface designed for stable and high-energy FZIBs to address this.

Can 3D cross-linked gel electrolyte be used for high performance lithium metal batteries?

In situ construction of 3D crossing-linked gel polymer electrolyte toward high performance and safety lithium metal batteries. J. Power Sour. 618, 235189 (2024). Wang, Q. et al. Molecular reactivity and interface stability modification in in‐situ gel electrolyte for high performance quasi‐solid‐state lithium metal batteries. Energy Environ.

What are gel polymer electrolytes (GPES)?

Gel polymer electrolytes (GPEs) are considered as a promising solution to replace organic liquid electrolytes for safer lithium (Li) batteries due to their high ionic conductivity comparable to liquid electrolytes, no risk of leakage, and high flexibility.
