Super polymer batteries, also known as high-capacity lithium polymer batteries, or high-voltage batteries, is a relatively new concept, the latest lithium polymer batteries, with higher technical difficulty and higher Cost, but because it not only has all the advantages and advantages of ordinary lithium polymer batteries, but also has a 10-20% increase in volume capacity density, weight energy density and safety performance, so from 2013 , began to quickly get applications on high-end mobile phones and mobile electronic devices.
　　 Super polymer batteries, also known as high-capacity lithium polymer batteries, or high-voltage polymer lithium battery cells, is a relatively new concept, the latest lithium polymer batteries, with higher technology Difficulty and higher cost, but because it not only has all the advantages and advantages of ordinary lithium polymer batteries, but also has an increase of 10-20% in volume capacity density, weight energy density and safety performance. So since 2013, it has been rapidly applied on high-end mobile phones and mobile electronic devices. Among them, the safety product: the electric mother powerqueenw is the leader.
　　 The increase in voltage can bring more capacity to the battery, bring longer battery life to the terminal device, and enhance the signal strength of the communication device. Take the Samsung NOTE2 battery label as an example. 11.78Wh, 3100mAh and 4.35V, 3.8V, 11.78Wh represent the total energy of the high-voltage battery, that is, how much power is stored, which is a sign that directly measures how powerful the battery is. The larger the value of the same battery, the more powerful the battery will be. 3100mAh represents the capacity of the battery, 4.35V represents the charge cut-off voltage, 3.8V represents the platform voltage of the battery, and 3100 and 3.8 are exactly 11.78Wh. The former is an important indicator for measuring the strength of high-voltage batteries (that is, cathode materials). The larger the capacity, the longer the battery is used, the longer the battery life (for the same discharge current); the latter is the cut-off voltage representing the battery charge. For the battery with the same positive electrode material, the higher the cut-off voltage, the battery capacity The higher the battery life, the longer it will be. Therefore, most of the current manufacturers of lithium batteries use a cut-off voltage of 4.2 ~ 4.5V, safe and reliable. The latter 3.8V represents the voltage platform of the battery (positive material). The higher the platform, the higher the specific energy of the battery. Compared with the previous battery, it is often a 3.7V platform. The battery of the high-voltage battery is 3.8V. Although it only increases by 0.1, the energy capacity of the battery is increased by 10%.
