Title: Progress in battery safety research at Tsinghua University

Venue: Johnson Hall, Howard Johnson Kangda Plaza Qingdao

报告摘要 | Abstract

Battery safety now stands at the forefront in our progressively electrified world, in the field of mobile electronics, transportation, and stationary energy storage. Battery thermal runaway (TR) that lead to fire and explosions arouses much concern. Ensuring the safety is not just a desirable goal; but has become a critical imperative. In this keynote, we'll elucidate three strategic pathways to battery safety: intrinsic safety, active safety, and passive safety.

Intrinsic Safety roots in the foundational design and materials of batteries. This pathway prioritizes preemptive measures. By innovatively tailoring battery chemistry and design, risks associated with TR can be substantially diminished from the onset. Active Safety embraces real-time vigilance, and harnesses advanced sensors, feedback mechanisms and intelligent batteries. Such proactive monitoring identifies potential TR triggers, facilitating immediate intervention and often preventing hazardous events entirely. Finally, recognizing that no system is infallible, passive safety centers on post-incident response. Incorporating features like fire-resistant casings or specialized venting systems, it ensures that even if TR occurs, the ramifications are contained and minimized.

An in-depth understanding of these mitigation techniques, functioning across material, cell, module, and system levels, is vital for both researchers and industry. Central to this discourse is the alignment of strategies with the foundational mechanisms governing TR.

This presentation will provide a panoramic view of the challenges and solutions associated with TR in batteries. Beyond a mere synthesis of existing knowledge, it will spotlight pioneering solutions and identify frontier areas demanding further exploration.
