Newer batteries, such as lithium-ion options, have very high energy densities and efficiencies, but are hampered by high costs. Supercapacitors, meanwhile, have very long cycle life and high efficiencies, but lower energy densities, needing more space for the same capacity.
Mas bagong mga baterya, tulad ng mga pagpipilian sa lithium-Ion, may napakataas na enerhiya density at kahusayan, ngunit hampered sa pamamagitan ng mataas na mga gastos. Supercapacitors, samantala, mayroon napakatagal ikot ng buhay at mataas na kahusayan, ngunit mas mababang enerhiya density, nangangailangan ng mas maraming espasyo para sa parehong kapasidad.
