What are the differences between lithium-ion batteries and lead-acid batteries?
1. Environmental impact
The positive and negative electrodes and electrolyte of lithium-ion batteries are made of environmentally friendly materials, so even if a lithium-ion battery leaks, it will not have a significant impact on the environment. In contrast, lead-acid batteries contain lead, sulfuric acid, and other chemicals; leaks in these batteries can cause serious harm to the environment and people.
2. Safety performance
The materials used in lithium-ion batteries are more stable than those in lead-acid batteries. Under high temperatures or overcharging conditions, the materials in lithium-ion batteries will not undergo structural collapse or form strong oxidizing substances. During over-discharge, lead-acid battery plates will sulfide, leading to a rapid deterioration of the battery quality. Therefore, lithium-ion batteries are safer than lead-acid batteries.
3. Cost differences
For the same capacity, lithium-ion batteries are one-third the size and weight of lead-acid batteries, which can effectively save installation space and eliminate the need to worry too much about the load-bearing capacity of the floor.
Unlike lead-acid batteries, lithium-ion batteries do not require frequent protection in a short period of time, and their cycle life is several times longer. Lead-acid UPS systems also require air conditioning to regulate the overall environment, while high-end lithium-ion UPS systems have many built-in regulating functions, significantly reducing additional equipment purchase costs, maintenance costs, and electricity bills.
Although the initial purchase cost of lead-acid batteries is lower than that of lithium-ion batteries, the overall cost of lithium-ion batteries is lower than that of lead-acid batteries when considering long-term use.
