If you are a heavy user of laptops, you should know about the life of laptop batteries and its prevention measures. However, have you ever encountered such a situation: your laptop battery is charged to about 60%, but it can't be charged anymore. Why is this? How Laptop Batteries Work First, we need to understand how laptop batteries work. Lap...

What is battery cycle number? The number of battery cycles and charging cycles are inextricably linked. The so-called battery cycle charging, that is, completing a complete charge and discharge cycle, then the number of cycles is actually a calculation method for the charging cycle. When the battery reaches a complete charging cycle, the numbe...

Oxygen Concentrator Working Principle Oxygen concentrators draw air from a room and filter out the nitrogen. This process provides the higher concentrations of oxygen needed for oxygen therapy. Oxygen concentrators can be large and stationary or small and portable. Oxygen concentrators differ from tanks or other containers that provide oxygen ...

Oxygen concentrators, as a device that can separate oxygen from the air and provide it for human breathing, play an increasingly important role in modern medical care and home care. According to different oxygen production principles and technologies, oxygen concentrators can be divided into many types, such as molecular sieve adsorption method,...

As time goes by, the laptop battery will inevitably age, degrade in performance, or even fail completely. When the laptop battery is damaged, people will choose to replace it with a new one. As for the old battery, many people may throw it into the trash can or put it in a corner until they forget about it. This practice is not environmentally f...

Lithium-ion batteries are complex in terms of environmental protection and involve the entire life cycle. Although production is polluting, they are highly efficient in use and improved recycling technology can reduce the environmental burden. With technological innovation and circular economy, they can be regarded as potential environmentally f...
