6 FAQs about [Battery discharge negative electrode quality]

What is a discharge curve in a lithium ion battery?

The discharge curve basically reflects the state of the electrode, which is the superposition of the state changes of the positive and negative electrodes. The voltage curve of lithium-ion batteries throughout the discharge process can be divided into three stages

Is lithium a good negative electrode material for rechargeable batteries?

Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).

How long after charge and discharge is a negative electrode discharged?
