Standby battery refers to the battery containing lithium (including lithium metal, lithium alloy, lithium ion, lithium polymer) in the electrochemical system. Spare batteries fall into two broad categories: lithium-metal and lithium-ion. Lithium-metal batteries are usually non-rechargeable and contain lithium in metallic form. Lithium-ion batteries do not contain the metallic form of lithium and are rechargeable, so how do you fix a spare battery? Here is a small series together to understand it.
How to repair the spare battery
1. Low temperature can make the electrolyte inside the standby battery change, and promote the chemical reaction of the battery just after freezing. When the spare battery is placed in a low temperature environment, the microstructure of the lithium film and electrolyte on the surface of the spare battery and their interface will change significantly, resulting in temporary inactivity inside the battery and reduced leakage current. So after recharging, the waiting time will increase.
2, there is another way, take off the spare battery, put it for about a week, the electricity will be slowly consumed, need to use the machine will be completely consumed. And then full charge, estimate your charging time must be very short, after full, disconnect again, repeated several times, absolutely effective.
How to repair the spare battery of mobile phone
1. Use a clean eraser or other material cleaning tool to gently wipe the metal contacts on the spare battery and the metal contacts on the mobile phone, which is conducive to the charging condition and lasting power.
2, the use of automatic shutdown of the old mobile phone spare battery with plastic wrap firmly wrapped, wrapped as far as possible, inside and outside a total of three layers, to ensure that the battery in a vacuum state. Then, wrap three more layers of newspaper on top of the plastic wrap to make the spare battery completely airtight. After 48 hours, take out the battery and remove the six layers of paper film one by one. There is no surface expansion or deformation caused by freezing of the spare battery. Let cool for a while, then charge.
3, let the standby battery close to scrap completely discharge, and then recharge to activate the battery. The solution: Deep discharge, which depletes the phone's internal power to recharge it further, requires some unconventional methods.
