2025年10月18日，一起涉及鋰電池自燃的航空安全事件在杭州飛往韓國仁川的國際航班上引發關注。當天，中國國際航空CA139航班原計劃從杭州蕭山國際機場起飛，預計當日15時抵達首爾仁川機場。然而，航班在飛行途中突發意外，迫使機組人員緊急採取備降措施。

事發經過顯示，航班於當地時間上午9時47分起飛。飛行過程中，一名旅客隨身攜帶的手提行李內的鋰電池突然自燃，產生明火拼冒出濃煙。多名乘客回憶稱，事故發生瞬間“砰的一聲，火直接噴出，客艙被煙熏黑”，現場一度驚險。機組人員立即啟動應急程式，按照安全操作規範進行處置，包括隔離火源、通知地面控制以及調整飛行路線。最終，航班在上午11時05分緊急備降至上海浦東機場，所幸事件未造成任何乘客或機組人員受傷。

中國國際航空隨後對外發佈通報，確認事故系旅客行李內的鋰電池自燃所致，並強調機組人員的專業處置有效避免人員傷亡。備降後，航空公司迅速調配另一架飛機繼續執行航班任務，計畫于13時30分重新起飛，保障旅客順利抵達目的地。

此次事件也引發公眾對鋰電池航空運輸安全的關注。根據中國民航局規定，鋰電池嚴禁托運，旅客隨身攜帶時必須符合額定能量限制（不超過100Wh），飛行中禁止使用充電寶。儘管本次航班為國際航線，不完全適用國內關於充電寶3C認證的強制規定，但事件仍提醒旅客在搭乘飛機時務必注意攜帶物品的安全合規性。

整體來看，這起事件凸顯了航空運輸過程中鋰電池潛在的火災風險，同時也體現機組應急處置能力的重要性。通過及時備降和規範操作，本次事故未造成傷亡，避免了更嚴重的安全事故，成為一次航空安全管理和乘客安全意識的警示案例。

On October 18, 2025, a safety incident involving a lithium battery fire occurred on an international flight from Hangzhou Xiaoshan International Airport to Incheon, South Korea, drawing widespread attention. The flight, Air China CA139, was scheduled to depart at 9:47 a.m. local time and arrive in Incheon at 3:00 p.m. However, during the flight, a lithium battery inside a passenger’s carry-on bag suddenly ignited, forcing the crew to take emergency measures.

According to reports, the battery fire caused visible flames and thick smoke inside the cabin. Several passengers recalled that the incident occurred with a “bang,” and flames shot out from the bag, filling the cabin with smoke. The flight crew promptly activated emergency procedures, isolating the fire, notifying ground control, and adjusting the flight path. The aircraft ultimately made an emergency landing at Shanghai Pudong International Airport at 11:05 a.m., with no injuries reported among passengers or crew.

Air China issued an official statement confirming that the incident was caused by a passenger’s lithium battery self-igniting. The airline praised the crew’s professional handling, which successfully prevented injuries or further escalation. Following the emergency landing, Air China arranged for another aircraft to continue the flight, with plans to depart at 1:30 p.m., ensuring passengers could reach their destination.

The incident highlighted ongoing concerns about the risks of carrying lithium batteries on flights. According to China’s Civil Aviation Administration, lithium batteries are strictly prohibited in checked luggage, and passengers may only carry batteries with rated energy not exceeding 100Wh in their carry-on. The use of power banks during flight is also prohibited. Although international flights are not fully subject to domestic 3C certification requirements for power banks, the event serves as a reminder for travelers to comply with aviation safety regulations when carrying electronic devices.

Overall, the CA139 incident underscores the potential fire hazards of lithium batteries in aviation and the critical importance of crew emergency training. Thanks to timely intervention and adherence to safety protocols, the situation was contained without casualties, serving as a cautionary example for both airlines and passengers regarding in-flight safety management.
