From equipment at Antarctic research stations to solar energy storage systems in the Sahara Desert, the stability of lithium batteries is directly related to the success or failure of missions in extreme environments. But can lithium batteries work properly in extremely cold -40°C or extremely hot 50°C? How will their performance change? Is there a risk of explosion? Based on battery chemistry principles and cutting-edge technology cases, this article will analyze the true performance of lithium batteries at extreme temperatures and explore how to break through the constraints of natural laws.

It is not uncommon for lithium batteries (such as mobile phones, cameras, and drone batteries) to be accidentally soaked in seawater during outdoor activities, seaside trips, or emergencies. The high salinity and conductivity of seawater may cause serious damage to the battery and even cause safety hazards. This article will provide you with a detailed analysis of the correct handling process and scientific principles of lithium batteries soaked in seawater to help you avoid risks and reduce losses.

There are various sayings about battery maintenance on the Internet, such as "full discharge once a month to calibrate the battery" and "avoid charging while using". But are these suggestions really scientific? Do modern batteries still need to be "calibrated" regularly? This article will reveal the truth for you.

In this era surrounded by electronic devices, batteries are the energy core of devices, and their maintenance is important. However, different devices have different battery types, usage scenarios, and frequencies, and the battery maintenance methods are also different. Today, let's take a deep look at the differences in battery maintenance for common electronic devices.

Power banks have long become a "life-saving artifact" for modern people to travel, but many people have misunderstandings about their use: some people are used to plugging them in as backup power, some people leave them idle for a long time after they are fully charged, and some people even treat power banks as "permanent plug-in devices." Are these behaviors really safe? Will long-term plugging in damage the power bank? This article will analyze the plug-in risks of power banks based on the principle of lithium batteries and provide a scientific maintenance guide.
