Lithium Battery Knowledge

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.

Winter is here, and many electric car owners have found that the range displayed when fully charged is "halved", the charging speed is slowed down, and even the power output is weakened. Some people say that "electric cars are naturally afraid of cold", while others question that "there are problems with the battery quality". What is the truth? This article will analyze the impact of low temperature on electric car batteries based on the chemical properties of lithium batteries, and provide a full range of solutions from charging skills to driving habits to help you say goodbye to winter range anxiety.

When buying a new mobile phone, many people will hear such advice: "The first charge should be fully charged for 12 hours" and "The first three times, the battery must be fully used and then fully charged to activate the battery." These sayings have been passed down from generation to generation by the elders, and are even regarded as "maintenance secrets" by some businesses. However, these suggestions actually come from battery technology that has long been obsolete. This article will trace the origin of the saying "activate the battery", analyze the characteristics of modern lithium batteries, and provide a scientific guide to charging new mobile phones.

Many people have heard the saying that "it is better to charge the phone after it shuts down automatically". Some people think that this can "calibrate the battery", while others think that it can extend the battery life. However, this concept actually originated from the early era of nickel-metal hydride batteries and is not applicable to the lithium batteries of modern smartphones. This article will explore the characteristics of lithium batteries in depth, reveal the truth of this misunderstanding, and share scientific charging suggestions.

With their flexibility and powerful shooting capabilities, drones have become a powerful tool for aerial photography, mapping, agriculture and other fields. However, many pilots have found that the life of drone batteries seems to be shorter than that of batteries for other devices. A brand new battery may have problems such as significantly reduced battery life, slower charging speed and even swelling after dozens of flights. What scientific principles are hidden behind this? How can we effectively extend the battery life? This article will deeply analyze the key reasons for the aging of drone batteries and provide practical maintenance guidelines.

Understanding the calculation method of lithium battery cycle times and the influencing factors is crucial for us to correctly use and maintain lithium batteries. When using electronic devices in daily life, we should try to adopt scientific charging methods, avoid extreme temperature environments, and choose lithium battery products with reliable quality. Only in this way can we extend the service life of lithium batteries, give full play to their performance advantages, and bring more convenience to our lives and work.
