Among others, polyurethane (PU) has attracted attention as a promising polymer electrolyte candidate for the future. The soft and hard segments of the polymeric chain given by polyols and isocyanates, respectively, give PU its characteristic multiphase structure. The PU''s soft segment can operate as a polymeric solvent to solvate the cations
In the light of this work, this review discusses PU as a polymer host and the approaches to increase its ionic conductivity, including polymer blending, copolymerization, crosslinking, filler...
If any compound from the polyurethane material is changed, it can lose its properties. Thus, we need to replace polyurethane with such an alternative that has similar properties as that of polyurethane. The present study makes a comparative analysis between polyurethane, a conventional material, and FIBI-buffer, a newly introduced material. To
In this manuscript the investigation of the heat-curable polyurethane (PU)/carboxymethyl cellulose (CMC) mixture as binder for Li-ion battery electrodes is reported. The experimental results demonstrate the outstanding thermal and electrochemical stability of PU, as well as the good electrochemical performance of cathode (NMC) and
A novel solid-state block copolymer (i.e., poly(urethane-b-siloxane, PUSR) electrolyte for lithium metal battery was designed and prepared. The structures of PUSR copolymer and PUSR-based solid polymer electrolytes (SPEs) were characterized by FT-IR and XPS, respectively; the physical properties, mechanical, thermal and
PU/LLZTO composite solid electrolytes improve Li + ions diffusion coefficient. The optimized LPCU electrolyte realizes RT conductivity of 2.2 × 10 −4 S cm −1. Li/LPCU/LiFePO 4 battery can achieve high energy density and cycling stability.
In this study, the design of the soft segments in a series of polyurethane and their properties as host materials for SPEs for high-temperature lithium metal batteries have been investigated. The design aspect has been extended to not only include the mechanical and ion transport properties but also the solubility of the materials in volatile
Polyurethane is a kind of materials that possess flexible structural designs, facile modifications (with polymers or fillers) and specific functions (self-healing, protect layer or high adhesion). Benefiting from those characteristics, a variety of dedicatedly designed PU-based PEs have been prepared and investigated, which exhibited high ionic conductivity, excellent
Using polyurethane-based materials, adhesives and pultrusion technology, we created a stronger, more rigid EV battery pack. Electric vehicles are growing in popularity, but are hampered by concerns about range, recharging time and especially a fear of battery fire during an accident. Using polyurethane-based materials, adhesives and pultrusion technology, we created a new
The flexible battery based on PUSPE-6000 can continue to work under a variety of harsh conditions, which expand the choice for the all solid-state electrolyte in the flexible wearable electronic device.

Polyurethane (PU), as a new type of matrix for PEs, is becoming increasingly
Herein, a series of double dynamic self-healing polyurethane polymer electrolyte (PUSPE-X) with hydrogen bonds and dynamic urea bonds was prepared by a simple polycondensation reaction. The constructed network exhibits excellent mechanical properties, strong self-healing and good shape memory properties.
In the field of chemistry, biological buffering agents play an important role. Among them, BES buffer (N, N-bis (2-hydroxyethyl) -2-aminoethanesulfonic acid), with CAS number 10191-18-1, has not only been widely used in biological experiments, but also demonstrated unique value in water-based polyurethane materials in recent years. BES powder
Polyurethane (PU), as a new type of matrix for PEs, is becoming increasingly attractive because of its flexibility of structure manipulation, fair ion transport ability, excellent mechanical strength, superior compatibility with other polymer matrixes and inorganic fillers, and outstanding toughness/flexibility.
Block copolymer electrolytes represented by polyurethane (PU) have become the forefront field of organic solid-state electrolytes for high-performance lithium-metal batteries due to their superb mechanical properties.

In this work, a reactive flame-retardant unit into the polymer framework via covalent bonding to create a nonflammable and stretchable polyurethane-based SPEs is introduced. Meanwhile, the mechanical strength of the polymer backbone is increased by grafting a rigid benzene ring unit, which remarkably suppresses the lithium-dendrite growth.
