Is TPU a good polymer?

TPU polymers exhibit thermal stability up to 300 °C and possess a thermoplastic nature that can be beneficial for battery applications. Additionally, TPU-based SPEs are biodegradable and significantly reduce costs. TPU is a cost-effective polymer with established synthesis technology .

How are membranes fabricated using TPU and LiTFSI?

Membranes were fabricated using TPU, LiTFSI, and SCN via solution casting. Four different TPU-based membranes (TPULxySzz, where x, y indicate the weight ratios of TPU and LiTFSI, and zz indicate the weight percentage of SCN in the SPE) were screened based on ionic conductivity and cost.

What are TPU-based solid polymer electrolytes?

TPU-based solid polymer electrolytes can thus offer enhanced mechanical strength without sacrificing ionic conductivity, unlike many traditional solid polymer electrolytes that need higher operating temperatures to improve ion conduction.

Are TPU-based Spes biodegradable?

Additionally, TPU-based SPEs are biodegradable and significantly reduce costs. TPU is a cost-effective polymer with established synthesis technology . These properties can be further tailored by modifying the soft and hard segments to suit the required specificity.

How can a TPU be tailored?

These properties can be further tailored by modifying the soft and hard segments to suit the required specificity. The TPU under investigation has soft segments consisting of polyols or long-chain diols and hard segments consisting of diisocyanates or short-chain diols.

What is FTIR spectra of TPU?

The solid-state Fourier Transform Infra-red (FTIR) spectra of TPU, LiTFSI, SCN, and the four SPEs. Band 2 - 1760 to 1675 cm −1: This band is also characteristic to TPU depicting the stretching vibrations of free and H-bonded carbonyl group (C = O) at 1729.10 cm −1 and 1699.77 cm −1, respectively (Fig. 6 b) .
