300mah battery Manufacturers

There are three main packaging forms of lithium battery, namely, cylinder, square and soft package. Different packaging structures mean different characteristics, each of which has its advantages and disadvantages. Among them, there are many types of cylindrical lithium batteries, such as 14650, 17490, 18650, 21700, 26500, etc.

In the past, all mobile power sources used 18650 batteries. 18650 batteries have gained the favor of many brands due to their light weight and large capacity. However, with the improvement of lithium polymer battery technology, manufacturers have gradually switched to lithium polymer batteries. Why do mobile power sources start using lithium polymer batteries?

According to the foreign media The Verge, batteries sometimes explode. Those explosion videos are scary, but scientists and startups have been working hard to build safer batteries. They are improving the battery design and testing new materials, hoping to solve the safety problem once and for all. But every method seems to have a trap, and the most practical solution at present may be the most boring. There are three strategies to improve battery: avoid using flammable liquid as solid battery; Make the battery module fireproof; Modify the existing functional characteristics of the battery slightly. At least as far as batteries are concerned, this change may come

In recent years, more and more new energy vehicles have entered people's lives. According to relevant data, by the end of 2020, the number of new energy vehicles in China has reached 4.92 million, accounting for 1.75% of the total number of vehicles, an increase of 1.11 million over 2019, or 29.18%. In addition, the growth of new energy vehicles has exceeded 1 million for three consecutive years, showing a trend of sustained and rapid growth, which indicates that the industry has a good development trend.

At present, power battery mainly includes lithium iron phosphate battery, lithium manganate battery and lithium ternary battery. And lithium iron phosphate battery supports half of China's lithium ion battery material industry. What is the working principle of lithium iron phosphate battery?
