Energy storage fireproof film

What is a fireproof polymer–polymer SSE?

Here, we report the first design of a fireproof, ultralightweight polymer–polymer SSE. The SSE is composed of a porous mechanic enforcer (polyimide, PI), a fire-retardant additive (decabromodiphenyl ethane, DBDPE), and a ionic conductive polymer electrolyte (poly (ethylene oxide)/lithium bis (trifluoromethanesulfonyl)imide).

Why do we need a multifunctional composite film?

The rapid development of portable flexible electronic devices means a multifunctional composite film with excellent thermal management capability, high electromagnetic interference (EMI) shielding, and a strong fire safety performance is urgently required.

Are MXene and montmorillonite fireproof EMI shielding films?

Herein, multifunctional fireproof EMI shielding films with excellent anisotropic thermal conductivity are constructed based on MXene and montmorillonite (MMT) via a simple vacuum-assisted filtration technique. The presence of MMT can protect the MXene from oxidation and endow the composite films with exceptional fire-resistant ability.

What is the EMI shielding effectiveness of composite films?

Importantly, the EMI shielding effectiveness is maintained at above 60 dB even after burning for 30 s. Besides, the composite films show outstanding Joule heating performance with a fast thermal response (<10 s) and a low driving voltage (<5 V).

Is there a thin porous polymer film?

There are also some thin porous polymer films in addition to electrospun polymers, such as polyimide [149, 150] and polyethylene films [135,151], through which thin polymer solid electrolytes of ~ 10 µm can be prepared by infiltration of PEO solution. However, CSEs also function as a separator. ...

Are energy storage devices dangerous?

However, the recent surge in fire accidents and explosions emanating from energy storage devices have been closely associated with the highly flammable components that make up these devices which have often led to the loss of life and property.
