1, good charge and discharge performance, allowing high power charge and discharge, floating charge and deep discharge. For lead-acid batteries, the greater the discharge current, the shorter the battery life) The deeper the discharge depth, the shorter the battery life. Even if the discharge depth of lithium battery reaches 100%, it will not affect the battery. In addition, lithium battery is not easy to short circuit, prevent short circuit caused by explosion and other safety problems

　　2. As a reaction site, the reactor is separated from the electrolyte storage tank, which fundamentally overcomes the self-discharge phenomenon of traditional batteries. The power depends only on the size of the reactor, and the capacity depends only on the storage and concentration of the electrolyte. The design is very flexible. When the power is connected, as long as the volume of the electrolyte storage tank or the volume or concentration of the electrolyte is increased without changing the size of the reactor, the energy storage capacity should be increased. The purpose of instantaneous charging can be achieved by replacing or adding the electrolyte in the charging state. It can be used to build energy storage power stations from kW to 100MW, with strong adaptability.

　　3, can be charged and discharged many times, the theoretical life is untold. The charge and discharge time ratio is 1:1, and that of lead-acid batteries is 4:1. In addition, lithium batteries have a fast charge-discharge switch response speed of less than 20 milliseconds, which is very good for balanced power supply.

　　4. Large degree of freedom in site selection, small footprint, automatic shutdown operation of the system, no acid fog, no acid corrosion. The electrolyte can be reused with no discharge and easy maintenance.

　　5. High energy efficiency. The energy efficiency of DC to DC can be more than 80 percent, compared to about 60 percent for lead-acid batteries. The battery status of each cell in the lithium battery pack is basically the same, which is easy to maintain.
