採軟包型式設計的鋰離子聚合物電池（Lithium-ion polymer battery, LIPB，簡稱軟包鋰電池），使其輕薄化且可客製各種樣態之模組而普遍應用於3C電子產品，如手機、行動電源等電能供應。然因其於長時間使用或特殊環境中可能因功率輸出或充放電異常而造成電池內部的短路而造成燃爆疑慮。本研究選用603450型鎳鈷錳酸鋰（LiNixCoyMnzO2, NCM）/石墨（Graphite, C）之軟包鋰電池，搭配自行開發設計之4L氣體–泡沫兩相阻燃系統測試儀（4L Gas-foam two phaseflame-retarding tester，簡稱4L阻燃系統測試儀）評估軟包鋰電池於鋁合金加熱盤進行電熱轉換之過加熱失效（Over-heating abuse）與直流1 C-rate充電率進行過充電失效（Overcharging abuse）建立電池燃爆之熱失控（Thermal Runaway）模式，並評估過充電效應下以泡沫–氣體阻燃氣體對於其燃爆消滅效應之效果，可提供軟包鋰電池過充失控模式與模組燃爆抑制設計。實驗設計係將軟包鋰電池置於4L阻燃系統測試儀內採過充電模式造成其短路燃燒時，評估測試消防系統之水成膜泡沫及滅火氣體之潔淨藥劑包含七氟丙烷（HFC-227ea）、氬氣（IG-01/Ar）、二氧化碳、氮氣（IG-100/N2）等比較抑制燃爆反應之阻燃差異性，再以直讀式氣體分析儀比較燃燒氣體主要成份。 |

Pouch lithium-ion polymer battery (LIPB) has competitive advantages involving a shaped package that can make any desired type of battery module for applying to 3C electronics, electric vehicles, or energy storage systems. However, the Li-ion battery may initiate short-circuit or thermal runaway failure due to high power output or overcharging/discharging state during its operation. The concern of combustible or explosive potential for the Li-ion battery is an important safety issue. A commercial 603450 pouch LIPB involving LiNixCoyMnzO2 (NCM)/graphite is tested for its overheating/overcharge abuse in this study. A self-designed 4L gas/foam flame-retarding tester, which can inject extinguishing agents to eliminate a fire case of LIPB. This study designs a fire suppression system for evaluating the short-circuit case of an overcharged LIPB to evaluate thermal runaway mode for a pouch LIPB under a 1 C-rate overcharging effect from a DC digital power supply. The combustible or explosive characteristics of a LIPB are evaluated to compare theflame-retarding difference using 3% AFFF (Aqueous Film-Forming Foam) and various fire extinguishing gases, including HFC-227ea, IG-01/Ar, CO2, and IG-100/N2, for batteryfire extinguishment. Furthermore, the residual gases are analyzed using an in situ recording gas analyzer. |
