The Wh used to charge and discharge lithium batteries is different.
Answer Explanation: The charging and discharging Wh of lithium batteries are different because the electrical energy loss is different during the charging and discharging processes. When charging, electrical energy must pass through processes such as circuits, chargers and chemical reactions inside the battery, which will consume a certain amount of electrical energy. Therefore, the electrical energy charged into the battery is less than the electrical energy charged. drums. When discharging, electrical energy flows from the battery and enters the electrical device through the wiring. It also loses a certain amount of electrical energy through the circuitry, heating and other processes inside the device, so the electrical energy released by the battery is less. that electric energystored inside the battery.
Actual answers and countermeasures: In order to make better use of lithium batteries, we need to understand and master the rules of charging and discharging lithium batteries. When charging, we can choose a suitable charger and charging power supply, and try to avoid using unsuitable chargers and power supplies to reduce power loss. When discharging, we can choose suitable electrical devices and circuits to minimize the loss of electrical energy in circuits, heating and other processes, so as to prolong the life of the battery and improve its efficiency. In addition, we can also carry out periodic charging and discharging maintenance of lithium batteries regularly to ensure battery performance and service life.
Because the process of charging lithium batteries is a process inwhich lithium ions enter and are integrated. The thickness of the pole piece will certainly increase once lithium is integrated. This does not mean gas will be present. generated during charging and the thickness will increase. The discharge process is a lithium ion detachment process, and the thickness of the pole piece will be reduced accordingly
I hope to adopt it, thank you
