Disadvantages of lithium battery energy storage

　　1、 High cost

　　Lithium batteries, as a representative of energy storage batteries, have high manufacturing costs. Compared to traditional lead-acid batteries and nickel hydrogen batteries, the material and manufacturing costs of lithium batteries are much higher. In addition, lithium batteries also have the problem of short lifespan and need to be replaced regularly, which increases the cost of use.

　　2、 Security risks

　　Lithium batteries are prone to safety accidents such as fires and explosions when overcharged, discharged, or damaged. In this way, safety issues cannot be ignored for lithium-ion energy storage systems. At present, although new safety technologies are constantly being applied to lithium batteries, it is still difficult to completely eliminate the safety risks of lithium batteries.

　　3、 Environmental issues

　　Lithium batteries can cause certain environmental pollution during production, use, and disposal. The extraction, extraction, and processing of lithium resources require a large amount of energy and water resources, which not only exacerbates the depletion of natural resources and environmental pollution, but also poses a certain threat to human health and ecological balance.

　　4、 High temperature issues

　　The working temperature of lithium batteries is usually between -20 ℃ and 60 ℃. Once the temperature is too high, lithium batteries will lose power and even cause accidents such as fire and explosion. How to ensure the normal operation of lithium batteries in high-temperature environments remains a bottleneck issue.
