Polymer18650 rechargeable battery lithium 3.7v 3500mah. lithium batteries bring more possibilities for intelligent wear

　　Polymer lithium batteries are mainly used in compact digital wearable products due to their heterosexual function. Due to the need to adapt to the curvature of fingers, wrists, and other limbs in the appearance of wearable products, it is also necessary to consider that the overall appearance of the product should not be too bulky to avoid affecting the wearing experience. Traditional batteries cannot meet the above requirements at all. Only this type of battery can perfectly match product space and battery life while meeting various shapes and thicknesses.

　　Taking Huawei's intelligent sports bracelet as an example: the overall size of the bracelet host is only 43 × twenty-five point four × 10.99mm, weighing 18g, with a battery capacity of up to 180mAh. Imagine such high standards, traditional batteries cannot match the current, only polymer lithium-ion batteries can match their performance.

　　Another example is the recently popular smart ring, which is an advantage and a new product that subverts people's cognition. The main complaint of the battery is that it must have a curved appearance, and the overall appearance must be particularly small, only 20mm, and the battery capacity can last for one week. This ring has a compact appearance and rich content - equipped with a pair of infrared sensors, gyroscopes, accelerometers, and temperature sensors.

　　Polymer lithium battery is a type of battery with chemical properties, characterized by high energy, small size, light weight, stability and reliability, short-term memory function, and can be made into various shapes, circles, or even arcs to meet the special needs of various small products. It is precisely because of these characteristics that this type of battery was commercialized in 1999, and in just three years, its sales have occupied nearly 9% of the lithium battery market share. By 2011, this number had exceeded 30%.
