Research on new flexible bipolar all-solid-state lithium battery technology -Lithium - Ion Battery Equipment
Bipolar all-solid-state lithium batteries (LIB) have attracted considerable attention as a solution to rising energy and safety demands. However, the use of inorganic solid electrolytes (sulfides or oxides), which are the most widely studied electrolytes in LIBs, in addition to long-standing problems such as chemical/electrochemical instability, interfacial contact resistance and manufacturing processability, will also cause Causes problems with mechanical flexibility and form factor.

【Achievements Introduction】
Recently, the team of Sang-Young Lee (corresponding author) of the Ulsan National Institute of Science and Technology developed a new type of flexible bipolar all-solid-state lithium battery through ultraviolet (UV) curing-assisted multi-level printing, which does not need to be used in traditional inorganic electrolyte-based batteries. High-pressure/high-temperature sintering process for all-solid LIB. Related to traditional inorganic electrolytes as core components in printed electrodes and gel composite electrolytes, this study used a flexible/nonflammable gel electrolyte composed of a sebaconitrile-based electrolyte and a semi-interpenetrating polymer network framework. The combination of rheological tuning of electrodes and GCE pastes (toward thixotropic fluid behavior) and multi-level printing of solvent-free drying enables the monolithic integration of tandem/in-plane bipolar stacked units onto complex-shaped objects. The relevant results were published in Energy & Environmental Science under the title "Flexible/shape-versatile, bipolarall-solid-statelithium-ionbatteries prepared by multistage printing".
【summary】
This study demonstrates that printed bipolar all-solid-state LIBs have excellent properties such as outstanding flexibility, shape diversity, charge/discharge performance, non-flammability and simplicity of fabrication, far exceeding those currently widely used (sulfides or oxides). ) inorganic electrolytes. The multi-level printing-based bipolar battery strategy described in the study holds great promise as an efficient and scalable platform technology to move bipolar all-solid-state batteries one step closer to commercialization.
