How to extend the capacity and life of lithium ion batteries?

The cleares the lithium-ion battery discharge, the greater the loss of the battery. Tomhartley, a professor of Electronic Engineering, Aiklang University, said that the battery is charged, the larger the loss of the battery will. The lithium-ion battery is preferably in an intermediate state of electricity, which is the longest battery life.

Tomhartley said that excessive and too low power state have an adverse effect on lithium-ion batteries. Most commercially available appliances or battery numbers can be derived from 80% of the discharge. Test statement, about some laptop's lithium-ion battery, often allow the battery voltage to exceed standard voltages 0.

1 volts, that is, from 4.1 volts to 4.2 volts, then the life of the battery will be reduced, then increased by 0.

1 volts, life is reduced to the original 1/3; Long-term low power or powerless state, the internal resistance of the battery is increasing, so that the battery capacity is small. NASA NASA makes it a total of 10% of the total capacity of the battery on the Hubble Space Telescope to ensure that the battery can repeatedly charge 100,000 times without having to update. Second, the temperature also has a large impact on lithium-ion battery life.

The environment of the freezing point may cause the lithium-ion battery to be turned in instantaneously, while the overheated environment will reduce the capacity of the battery. Therefore, if the notebook uses an external power supply to take the battery, the battery will be scrapped in the high heat of the notebook for a long time. This can always summarize the following points to extend the lithium ion battery capacity and life.

1. If the long-term use of an external power supply is powered by the laptop, or the battery is more than 80%, immediately remove the battery. Usually charging does not need to overfill the battery, charged to about 80%.

Adjust the power options for the operating system, adjust the electricity alert to more than 20%, and the lowest battery power is not less than 20%. 2. Small electronic devices such as mobile phones should immediately disconnect the power cord (including the USB interface of the charging function), which will damage the battery.

It is often charged, but it is not necessary to fill the battery. 3. Whether it is for a notebook or a mobile phone, you must not let the battery exhausted.
