| titleOfInvention | Charging method and charging device of lithium metal battery |
| abstract | The invention relates to a charging method and a charging device for a lithium metal battery. The charging method is a coupled charging method of a first constant voltage charging and a subsequent constant current-constant voltage, namely a CV 1 -CC-CV 2 charging method. The charging method proposed by the present invention adopts constant voltage charging in the initial stage, which is essentially different from the initial constant current charging in the standard charging method. Using the charging method of the present invention, the initial constant voltage stage is introduced before the standard charging protocol, which can strengthen the internal electric field of the battery, promote the migration of lithium ions in the electrolyte to the negative electrode, and slow down the rapid consumption of lithium ions at the interface during fast charging, which is similar to the traditional charging method. In comparison, the method can make the lithium deposition dense and smooth, and can inhibit the growth of lithium dendrites, prolong the service life, and improve the safety of fast charging. |
