TWS is the abbreviation of true wireless stereo, which is based on the development of Bluetooth chip. TWS headset is a new intelligent wearable product that applies TWS technology to the Bluetooth headset field. The battery life of the headset is an important factor that most consumers pay attention to when purchasing Bluetooth headsets.
Development background of Bluetooth headset lithium-ion battery: in 2016, Apple released the first generation of airplads. Due to the stability and portability of the product quality, manufacturers have laid out the Bluetooth headset market. In addition, as mobile phone manufacturers gradually give up the jack, this has also brought new growth points to the blue ear Market. Thanks to the strong demand for Bluetooth headsets, the demand for lithium-ion batteries for headsets is also gradually increasing.
1、 Market overview of Bluetooth headset battery
At present, TWS headset batteries in the market are mainly divided into button type batteries and needle type soft pack batteries. Among them, the soft pack batteries have relatively low energy density, high button type battery energy density and small space occupancy. Therefore, they are favored by well-known brands of Bluetooth headsets. For example, apple and Sanxing all use button type lithium-ion batteries.
2、 Lithium ion battery enterprises of Bluetooth headset
Bluetooth headsets are divided into three grades: high, medium and low. Among them, the high-end product is the button battery with winding process. Because there is no gap in the battery, the battery has good overall performance and high energy density. The representative enterprises are Germany Valta, Yiwei lithium energy, etc; The mid-range product is the button type battery with lamination process, and the product performance is slightly lower than that with winding process. The representative enterprise is Zijian electronics; The low-end products are needle shaped soft bags. Because these products occupy a large space and have a lower energy density than button batteries, some companies are also turning to the production of button batteries, such as LG and ATL. At present, the Bluetooth headset market is dominated by overseas brands such as Valta. Domestic enterprises are actively seizing the market and expanding market share by expanding production capacity.
Thanks to the rapid growth of TWS earphone shipments, the demand of the battery industry has also changed. A pair of earphones requires two earphone batteries and a charging compartment battery. The demand for earphones is increasing, and the demand for batteries is also increasing; On the other hand, the continuous improvement of battery life requirements means that battery manufacturers' production requirements for battery performance and capacity are also continuously improved.
