6 FAQs about [New Energy Battery Discharge Method]

Is electrochemical discharge a good way to discharge small batteries?

Out of the different LIB discharge methods, electrochemical discharge is widely accepted among scientists as a robust method capable of the large-scale discharge of small batteries. Accuracy of the voltage reading is critical, as it can affect the safety of the crushing process.

What is the best method for discharge pretreatment of lithium ion batteries?

The safest and most effective solution is to connect resistors at both ends of the battery to consume the residual electric energy of the spent LIBs. However, due to different battery sizes, this method is not economically feasible. Based on this principle, two feasible methods have been derived for discharge pretreatment.

Why do we need external electrochemical discharge for lithium ion batteries?

External electrochemical discharge can be used to eliminate the effect of corrosion. Some measurement devices may involve in discharging the batteries during experiments. The demand for Lithium-ion batteries (LIB) is expected to increase exponentially due to the electrification of society.

What happens when a battery is discharged?

During the discharge of a LIB, the internal state of the battery is non-linear with heterogeneities in the concentration of the Li-ions in both electrodes and the electrolyte. When battery discharge is terminated, the current in the circuit is switched off, and the Li-ions move from an area of higher concentration to a lower concentration area.

How to measure battery voltage during electrochemical discharge?

To measure the voltage of the battery during electrochemical discharge of the batteries, two different devices were used: a digital voltmeter (Fluke 87 V TRMS Industrial Multimeter) and an IviumStat potentiostat (Teamator, Sweden).

Does voltage rebound affect battery discharge pretreatment?

Therefore, the effect of voltage rebound was also studied, and the obtained results showed that the voltage was over-discharged after flake-graphite discharge, which would cause irreversible damage to the anode material of the batteries and lead to battery failure. This is of great significance for the discharge pretreatment of spent LIBs.
