Lithium-ion batteries are the best energy storage system for everyday residential use and for EV’s because they take up little space while still storing a huge amount of energy. Also, their high DoD means you can use more of the energy stored.
The battery will last longer, so it won’t need to be replaced as often as a lead-acid battery. Plus, their higher efficiency means that you get to use more of the energy-giving you more bang for your buck.
Non-toxic and extremely stable to the environment also make choosing Lithium more safe and responsible.
