Introduction: Now the battery technology is so developed, but the general flight time of drones is 10-30 minutes. At this time, someone asked why the battery of the drone cannot exceed 30 minutes? Is it really?

The application and promotion of electrochemical batteries have changed the current industrial pattern. Among them, lithium batteries have developed rapidly in the field of power and energy storage. At present, the debate on the priority of the two popular lithium batteries, "lithium iron phosphate battery" and "ternary lithium battery", has never stopped. This year, the two are pushed to the forefront again.

Lithium iron phosphate battery is a lithium ion battery with lithium iron phosphate (LiFePO4) as the cathode material and carbon as the cathode material. The rated voltage of the single battery is 3.2V, and the charging cut-off voltage is 3.6V~3.65V.

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.

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.

Li Polymer Prismatic batteries are rapidly becoming a popular power solution across industries such as consumer electronics, medical devices, IoT products, and energy storage systems. Their lightweight design, high energy density, and customizable form factors make them ideal for modern compact devices. This in-depth guide explores the advantages, applications, technical characteristics, and selection tips for Li Polymer Prismatic batteries. It also explains why manufacturers and engineers increasingly rely on advanced battery providers like Encore Energy for high-performance lithium polymer battery solutions.
