1. The 18650 battery is cylindrical with transparent liquid inside. This is due to the battery concept and material. 18650 is suitable for high current, so that almost all laptops and electric cars are basically designed with 18650 batteries; only super notebooks, This is due to environmental protection and energy saving, so polymer lithium-ion batteries can be used instead of 18650 batteries, especially for tablet computers, etc. Digital cameras are due to the large voltage and instantaneous high current required for charging and discharging of the photo flash, so only 18650 can be used. Similar batteries, only slightly smaller;

The power recovery decision-making consultation salon co sponsored by the Beijing Association for Science and Technology and the Literature and Information Center of the Chinese Academy of Sciences was held in Beijing Green Space Center yesterday. Fei Weiyang, academician of the Chinese Academy of Sciences, pointed out that in recent years, the key technology of pure electric drive has made great progress, and the core technology of electric vehicles represented by lithium ion has made a major breakthrough. However, the massive application of lithium batteries will also lead to the retirement of a large number of lithium batteries. Therefore, it is necessary to strengthen the research and development of advanced technologies for lithium battery recycling to achieve safe and efficient disassembly and overall recovery of valuable metals and prevent secondary pollution.

In many cases, the existing lithium battery market that equipment manufacturers need cannot meet their needs. At this time, lithium battery customization cannot be avoided. However, many manufacturers have little knowledge about lithium battery customization. Due to the impact of poor information, it is very likely that some unscrupulous battery manufacturers will make a hole in the market. Today, let's take a look at the customization of lithium batteries

Over long-term use, the internal resistance of a lithium ion battery single cell inevitably increases. This increase in internal resistance is directly related to the battery's output efficiency, temperature rise, and safety performance.
