      Lithium battery discharge

      Discharge platform time

      The discharge platform time refers to the discharge time to a certain voltage when the battery is fully charged. For example, measure the discharge platform time of a certain ternary battery at 3.6V. Charge it to a constant voltage of 4.2V and stop charging when the charging current is less than 0.02C. After fully charging, let it stand for 10 minutes. The discharge platform time at any rate of discharge current is the discharge platform time at that current.

      Due to the voltage requirements of some appliances using lithium-ion batteries, if the operating voltage is lower than the required value, it may cause malfunction. So the discharge platform is one of the important standards for measuring the performance of batteries.

      Self discharge rate

      Self discharge rate, also known as charge retention capacity, refers to the ability of a battery to maintain the amount of electricity stored under certain conditions in an open circuit state. Mainly influenced by factors such as the manufacturing process, materials, and storage conditions of batteries. It is an important parameter for measuring battery performance.

      efficiency

      Charging efficiency refers to a measure of the degree to which the electrical energy consumed by a battery during the charging process is converted into the chemical energy that the battery can store. Mainly affected by battery technology, formula, and working environment temperature of the battery. Generally, the higher the ambient temperature, the lower the charging efficiency.
