How can I safely pack lithium-ion batteries for my flight?

Inspect your rechargeable devices before your flight and keep them nearby at all times. Powering off your devices during flight may also lower your risk. Learn more about flying with lithium ion batteries safely here.

How common are lithium-ion battery incidents on planes?

There are approximately two thermal runaway incidents reported per week out of roughly 180,000 weekly flights in U.S. airspace. While incidents have increased 28% over the past five years (2019–2023), they remain relatively rare.

Which devices cause the most incidents?

In 2023, e-cigarettes were responsible for 35% of reported incidents on passenger flights, followed by power banks at 16%. Together, these two types of devices account for over half of all thermal runaway incidents.

Can I pack my laptop, phone, or tablet in checked luggage?

No, devices containing lithium-ion batteries should not be packed in checked luggage. Our research shows that devices that enter thermal runaway in checked baggage cannot be accessed by crew while in-flight, and fires may not be detected as quickly in the cargo hold as they would be in the cabin.

What’s the safest way to transport my devices during a flight?

Keep devices in the cabin where they can be monitored. Approximately 87% of incidents occur on aircraft, with about 60% happening near passenger seats where they can be quickly detected and addressed. Keep devices in sight and easily accessible rather than in overhead bins.

Is it safe to charge my devices during flight?

According to TRIP data, only 6% of incidents involved charging using aircraft USB or AC outlets. While charging isn’t necessarily a major risk factor, it’s still important to monitor devices while charging and use certified charging accessories.

您面临的风险是什么？

手机和便携式电源包等可充电设备是空中旅行的必备品，但却给乘客、机组人员和飞机带来严重的安全隐患。如果这些设备中的锂离子电池损坏、充电不当或制造不良，就会过热并进入热失控状态--这种危险状态可能导致起火或爆炸。适当的教育和安全标准有助于防止这些事故的发生。

数字

将鼠标悬停在下面的每个统计数据上，了解适当的航空安全措施对预防潜在危害事件的影响。

28%

2019-2023 年间与锂离子电池有关的航空事故频率增加。

通过 ULSE 的热失控事件计划 (TRIP），我们正与航空业危险品和危险材料专业人士合作，密切关注锂离子电池事故数据，更好地了解这一日益严重的航空安全问题的规模和复杂性。TRIP 是与航空业危险品专业人士共同开发的，也是为航空业危险品专业人士开发的，它是一个安全、自愿的系统，用于处理与航空相关的锂离子电池事故。主要的客运和货运航空公司都参与了 TRIP，自愿向 TRIP 数据库报告事故，并参与以下活动计划峰会来解决风险问题。

70-80%

主要航空公司的机场地面支持车辆都采用了锂离子电池技术。

虽然热失控事故多发生在 4 万英尺以上的高空，但机场地面运输车辆也会发生一些热失控事故。UL 5840 促进了这些车辆的安全运行，包括皮带和集装箱装载机、行李拖车、运水车和平台升降机。

35%

2023 年，锂离子电池事故的起因是客机上的吸烟设备，其次是电源箱。

我们的标准 UL 5800 涵盖电池防火产品，提供了防火测试和性能标准，以评估用于遏制锂离子电池起火的防火产品以及飞行过程中的相关影响。

50%

的美国人表示对锂离子电池一无所知。

此外，58% 的消费者认为锂离子电池的风险与他们个人无关，63% 的消费者表示不熟悉如何降低风险。教育计划或许能改善这些数据。

继续阅读，从和您一样的人身上了解预防的力量。

标准在行动

安全标准就像一本由专家编写的指导手册，用于指导产品、服务和系统的测试，使其对您更加安全。

我们的标准可减少和降低锂离子电池事故，从而确保您的空中安全。

回顾我们在航空安全领域的悠久历史

20 世纪初，当人们开始尝试飞行时，我们的组织与美国国家飞机保险商协会合作，检查飞机，制定制造标准，并制定了美国第一部民用飞机规则，从而帮助推动了这项技术的安全发展。

一个多世纪后的今天，ULSE 继承了这一传统，为从地面设备到商用无人机以及乘客携带上飞机的商用设备制定了全面的标准--这样，当飞行员和乘客踏上飞机时，他们的安全就有了严格的保障。
