Embodiment

[0055] The following examples describe specific aspects of some embodiments of the present disclosure to illustrate and describe those of ordinary skill in the art. This embodiment is not to be construed as limiting the disclosure, since this embodiment provides only a particular method that facilitates and practice some embodiments of the disclosure.

[0056] Overview

[0057] In this embodiment, a super molecular polymer engineering is introduced to form a gel polymer electrolyte having excellent mechanical properties. By fitting the hydrogen bonding 2-urea-4-pyrimidine (UPY) portion into the ion conductive polymer backbone, an ultrasive polymer electrolyte is formed, and the mechanical properties are independent of ion conductivity. This polymer known as the tensile lithium ion conductor (SLIC) can be used as an elastic polymer electrolyte, and is about 2 × 10 when gelation with an appropriate amount (e.g., about 20 wt.%) Of plasticizer gel -4 S cm -1 Ion conductivity. The ext...

Abstract

A battery includes: 1) an anode; 2) a cathode; and 3) a solid or gel electrolyte disposed between the anode and the cathode, wherein the electrolyte includes a supramolecular polymer formed of, or including, molecules crosslinked through dynamic bonds, and each of the molecules includes an ionic ally conductive domain.

Description

[0001] Cross-reference [0002] The benefits of the US Provisional Application No. 62 / 794, 481 submitted on January 18, 2019, which are incorporated herein by reference. Technical field [0003] The present disclosure generally relates to a tensile battery. Background technique [0004] Recent technical progress and continuous miniaturization of electronic products narrow the gap between human and technology. Humanities are increasingly in contact with electronic devices in the form of personal computers, portable smartphones, and wearable electronic devices. These electronic devices are usually very hard and do not fit the human body. Looking forward to the future, people have a strong interest in developing electronic equipment closer to the human body. Such applications include human soft robots, sensors that fit the human skin, and electronic devices that can be directly implanted into the human tissue. The latest progress of the detachable electronics promotes these applicat...
