Current Updates and Key Techniques of Battery Safety

Dear Colleagues,

Ensuring battery safety is paramount in today's technological landscape. Batteries power a myriad of devices, from smartphones to electric vehicles, making their safe operation crucial for both user well-being and environmental sustainability. The consequences of battery malfunctions can be severe, ranging from device damage and financial losses to life-threatening situations such as fires and explosions. Moreover, with the increasing scale of battery deployment in critical applications like energy storage systems and grid integration, the need for robust safety measures becomes even more pressing. By prioritizing battery safety through rigorous testing, standards compliance, and continuous innovation in materials and design, we can mitigate risks, build trust in battery technologies, and unlock their full potential for a cleaner, more efficient future.

This Special Issue explores the current updates and key techniques in battery safety, addressing the challenges, advancements, and future prospects in ensuring the safe operation of battery systems.

Battery safety remains a critical priority in enabling the widespread adoption of battery-powered technologies across various sectors. By leveraging advancements in materials, design, testing, and regulatory frameworks, stakeholders can collectively work towards ensuring the safe and sustainable deployment of battery systems in the years to come. Continued research, collaboration, and innovation will be key to addressing evolving safety challenges and maximizing the potential benefits of battery technology. Potential themes include the following：

1. Importance of Battery Safety
