Wearable device battery how to choose? What are the advantages?

In recent years, the development of wearable technology by leaps and bounds, what is the wearable device? Wearable devices are worn directly on the body, or integrated into the user’s clothes or accessories, a portable device. So what are wearable devices? For example, sports bracelets, smart watches, smart clothing, virtual reality devices, head-mounted displays, smart accessories and more. In these wearable devices, the advantages and disadvantages of the wearable device battery directly affect the wearable device quality, wearable device battery can be seen on the wearable device is a very important part! What wearable device manufacturers choose what kind of battery, the following describes the wearable device battery (Li-ion) What are the advantages?
Wearable device battery (Li-ion) has the following advantages:
1, single cell voltage high voltage 3.6-3.8V;
2, the specific energy is larger, the actual specific energy that can be achieved at present is 100-115Wh / kg and 240-253Wh / L (twice NI-Cd and 1.5 times that of Ni-MH). In the future, as the technology develops, the specific energy may reach as high as 150wh / kg and 400wh / l;
3, the cycle life of plants, generally can reach more than 500 times, or even 1000 times, for small current discharge of electrical appliances, battery life, will double the competitiveness of electrical appliances;
4, safety performance, pollution-free, no memory effect, as the predecessor of Li-ion lithium battery, lithium metal dendrite easy to form a short circuit, reducing its application areas: Li-ion does not contain cadmium, lead, mercury, etc. The pollution of the environment elements; some of the Ni-Cd batteries have a major drawback ills for memory effect, severe beating battery use, but Li-ion does not exist in this regard;
5, self-discharge small, room temperature fully charged Li-ion storage after 1 month self-discharge rate of about 10%, much lower than 25-30% Ni-Cd, Ni, MH 30-35%.
So, at present wearable device battery is more Li-ion battery.
