1、 Increase energy density

　　The energy density of energy storage lithium batteries is an important factor affecting energy storage efficiency and cost. At present, researchers mainly improve the material and structure of batteries to increase their energy density, in order to increase the energy storage capacity of lithium batteries and reduce energy storage costs.

　　2、 Improve security

　　In energy storage systems, the safety of batteries is crucial. Currently, researchers mainly improve the safety of energy storage lithium batteries from the following two aspects: on the one hand, improve the structure and materials of the batteries to enhance their seismic and vibration resistance capabilities, in order to reduce accidental damage to the batteries during the use of energy storage systems; On the other hand, researchers are still exploring new electrolyte and electrode materials to improve the thermal stability and safety of batteries.

　　3、 Improving cycle life

　　The cycle life of energy storage lithium batteries is an important factor affecting the service life and maintenance cost of energy storage systems. At present, researchers mainly improve the cycle life and service life of energy storage lithium batteries by optimizing the charging and discharging management system of batteries, improving the production process of batteries, and other means to reduce the maintenance and replacement costs of energy storage systems
