Is Lithium-Ion Battery Or Lead-Acid Battery More Suitable For Home Energy Storage Systems?

Release time: May 31, 2022

Home energy storage systems are similar to micro-energy storage power stations and are not affected by the pressure of the urban power supply. At low power points, the battery pack in the home energy storage system can be self-charged for use during peak times or power outages. In addition to being used as an emergency power source, the home energy storage system can also save household electricity costs by balancing the load. Then the home energy storage system also has relatively high requirements for the battery, not only the battery capacity must be high, but also the longer battery life. The following is an introduction and comparison between lithium-ion batteries and lead-acid batteries.


Service life


The maximum number of cycles of lead-acid batteries is about 1,000, while most of the cycles of lithium-ion batteries are between 1,000-4,000. Therefore, in the high-frequency charge and discharge cycle of solar energy storage systems, users will have to replace lead-acid batteries frequently.


In terms of working life, it is expected that lithium-ion batteries will continue to operate for 8-10 years, and they can be charged and discharged to a higher level without significantly reducing the capacity. We recommend the use of high-quality lithium battery energy storage connectors, which can effectively reduce the maintenance cost of household energy storage and extend its service life.


Volume and weight


Lead-acid batteries also have the problem of low discharge and charge and discharge efficiency. They consume extra energy during use and cannot be charged and discharged as quickly as lithium battery systems. Therefore, under the same conditions, lead-acid batteries will require more capacity and space, that is, more volume and weight.


Lithium-ion batteries used in home energy storage systems are not light, but compared with lead-acid batteries of the same specification, their volume and weight are reduced by about 30%; they can be charged faster at higher voltages, and their safety performance is also greater. 


Environmental protection


Lead is a toxic heavy metal, even if it is recyclable, a slight mishandling can cause pollution.


Lithium batteries are green and environmentally friendly. No matter they are produced, used, or scrapped, they do not contain or produce any toxic and harmful heavy metal elements and substances such as lead, mercury, and cadmium.


Of course, there are many advantages of lithium-ion batteries. In short, lithium-ion batteries have more advantages than lead-acid batteries in energy storage applications, and as the cost drops, they will be more and more widely used in energy storage systems.


In summary, it can be seen that the performance of lithium-ion batteries is more suitable for home energy storage systems than lead-acid batteries in any aspect, and this is also the future trend.
