Small-capacity polymer batteries: Tiny size, mighty power Please provide the text you would like translated.

Despite its "miniature" size, the small-capacity polymer battery has become the energy heart of many delicate devices thanks to its unique 

advantages. It inherits the high safety and flexibility of polymer batteries, with a thickness starting from just 0.5 millimeters, making it suitable 

for various exquisite designs. At the same time, it features high energy density and long cycle life, providing stable and lasting power for small 

devices. Please provide the text you would like translated.

In the field of wearable devices, small-capacity polymer batteries are the core partners of smartwatches and fitness bands. Take the Apple Watch 

Series 9 as an example. It is equipped with a small-capacity battery the size of a coin, yet it can support all-day heart rate monitoring, blood 

oxygen detection and other functions, achieving a 18-hour battery life. The Huawei Watch GT 4 also relies on a small-capacity polymer battery 

to achieve an ultra-thin dial design while achieving a two-week long battery life. Wireless headphones also depend on this type of battery to 

achieve portability and long listening time. The AirPods Pro 2 has a single-charge battery life of 6 hours, and with the small charging case, the 

total battery life exceeds 30 hours, meeting the all-day usage needs of users; the Sony WF-1000XM5, equipped with a small-capacity battery, 

can still achieve a strong 8-hour battery life even when the active noise cancellation is on. Please provide the text you would like translated.

In the field of portable medical devices, small-capacity polymer batteries are also indispensable. Devices such as blood glucose meters and 

portable insulin pumps need to be small in size while maintaining sufficient power for multiple tests or injections. Small-capacity polymer 

batteries precisely meet these requirements, providing reliable mobile medical support for patients. Moreover, small smart home sensors and 

wireless mice also benefit from the application of small-capacity polymer batteries, achieving more convenient and longer-lasting usage 

experiences. Even in the emerging field of micro drones, small-capacity polymer batteries, with their lightweight and high burst power 

characteristics, enable drones to achieve flexible flight, demonstrating the charm of "small batteries, big energy".
