How did your phone manage to charge so fast?

Portable removable electronics are becoming more powerful and consume electrical energy faster and faster. Therefore, rechargeable batteries with greater range and capacity are needed to provide electrical energy for them. Lithium-ion battery fast-charging technology has developed rapidly in recent years.

Lithium-ion battery fast charging technology means that the charging voltage of the charger is increased and the charging current is increased, so that the battery is charged quickly. For example, in cell phones and notebooks, ordinary charging technology generally uses a charging current of 0.5C (here 1C current is explained as: 1 times the current of the battery capacity, such as 2600mAh battery, 1 times the current of the battery capacity is equal to 2600mA, then 1 hour can be full), 30 minutes can only fill 25% of the power, while fast charging technology now uses 1.2 C to 1.8 C charging current, can be achieved in 30 minutes full of 60% to 80% of the power.

Such fast charging technology, reflecting the obvious advantages of lithium-ion batteries, mainly in the following areas: first, high energy density, if the same electrical energy capacity, lithium-ion batteries are smaller, lighter, more portable and thin; second, the open-circuit voltage of lithium-ion batteries is also higher than other positive ion batteries, the use of longer; finally, lithium-ion batteries can be charged with high current, a feature that provides the possibility of fast charging.

Lithium-ion batteries are widely used because of high energy density, long cycle life, no memory effect and green features, specifically in the following areas:

1, fast-charging lithium-ion batteries in the field of cell phones will be important applications. Lithium-ion batteries are commonly used in smart phones, but due to the high power consumption of smart phones, long charging time of cell phone batteries, which restricts the use and development of smart phones, lithium-ion batteries with fast charging capability will make up for this defect, improve the charging speed of cell phone batteries to meet the use of smart phones.

2, in the vehicle equipment, the application of lithium-ion batteries has also become an important development direction, fast-charging lithium-ion batteries not only solve the problem of charging the vehicle battery, but also improve the charging efficiency of lithium-ion batteries, to improve the power supply capacity of vehicle equipment, to meet the normal use of vehicle equipment has an important role.

3, charging cell phones to a wide variety of mobile charging devices, in this field, fast-charging lithium-ion batteries can not only quickly charge mobile charging devices, but also improve the function of mobile charging devices, which has an important role in promoting the development of mobile charging devices.
