There are many kinds of electric boats, such as electric fishing boats, electric sightseeing boats, electric kayaks, etc., but generally speaking, they are mainly divided into two categories: unmanned model electric boats and manned practical electric boats.

It is believed that many people in the battery market can hear the term 18650 battery, but few friends have seen the battery labeled 18650 battery in the market. At this time, some friends will have questions: What is the 18650 battery? Today, this article will solve this problem, and also answer the difference between 18650 battery and flexible lithium battery?

The left side of the lithium iron phosphate battery is an anode composed of an olivine structure material, which is connected to the battery with aluminum foil. On the right is the negative electrode of the battery composed of carbon (graphite), which is connected to the negative electrode of the battery by a copper foil.

There are two basic processes of internal short circuit of battery caused by metal foreign matters, as shown in Figure 1. In the first case, large metal particles directly pierce the diaphragm, causing a short circuit between the positive and negative electrodes, which is a physical short circuit.

The Ministry of Industry and Information Technology of the People's Republic of China has revised the Regulatory Conditions for the Lithium Ion Battery Industry and the Interim Measures for the Administration of Regulatory Announcements for the Lithium Ion Battery Industry, forming the Regulatory Conditions for the Lithium Ion Battery Industry (2018 version) and the Interim Measures for the Administration of Regulatory Announcements for the Lithium Ion Battery Industry (2018 version), which will be formally implemented from February 15, 2019. This method greatly strengthens the management of the lithium-ion battery industry, guides the transformation and upgrading of the industry, vigorously cultivates strategic emerging industries, and promotes the healthy development of the lithium-ion battery industry. There is no doubt that the new national standard for electric vehicles has had a significant impact on lead-acid batteries

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
