Factory-charging a new lithium-ion battery with high currents significantly depletes its lithium supply but prolongs the battery’s life, according to research at the SLAC-Stanford Battery Center. The lost lithium is generally usually used to form a protective layer called SEI on the negative electrode.
Do not boost lithium-based batteries back to life that have dwelled below 1.5V/cell for a week or longer. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short. When recharging, such a cell might become unstable, causing excessive heat or show other anomalies.
The positive electrode of a newly minted battery is 100% full of lithium, said Xiao Cui, the lead researcher for the battery informatics team in Chueh’s lab. Every time the battery goes through a charge-discharge cycle, some of the lithium is deactivated. Minimizing those losses prolongs the battery’s working lifetime.
Lithium-rich materials (LRMs) are among the most promising cathode materials toward next-generation Li-ion batteries due to their extraordinary specific capacity of over 250 mAh g −1 and high energy density of over 1 000 Wh kg −1. The superior capacity of LRMs originates from the activation process of the key active component Li 2 MnO 3.
The solution is the method described above: jump the sleeping LiFePO4 battery with another battery or power source of identical nominal voltage until it wakes up. At that point, it will start reading a voltage in its normal voltage range, and your lithium battery charger should start charging it like normal.
If you’re charging your battery with a lithium battery charger, connect your charger and it should start charging normally. Fully charge your battery. Most 12V LiFePO4 batteries are fully charged at 14.4-14.6 volts. Once it’s charged, you can again use your battery like normal.
