Question: 1 / 400

What is a primary advantage of lithium-ion batteries in power systems?

They are more hazardous

They have a low self-discharge rate

The primary advantage of lithium-ion batteries in power systems is their low self-discharge rate. This attribute allows lithium-ion batteries to retain their charge for longer periods when not in use, making them highly efficient for various applications. In power systems, this is particularly beneficial for storage solutions, as it ensures that energy remains available for use without significant losses over time. The low self-discharge rate enhances the overall reliability and performance of devices that rely on battery power, allowing for longer intervals between recharging cycles and improved energy management.

In contrast, the other choices highlight disadvantages or issues associated with battery technology rather than advantages, which is why they do not align with the question about the benefits of lithium-ion batteries.
