why hi?verylight elementachive high specific energy density -amount of energy stored per unit mass.Li+ has very large the SRP, so Li-ion batteriesproduce a higher voltage percell than others.mas voltage of 3.7V per cell, nearby X3higher than 1.3V per cell that No-Cd cyWi - metal hydride balteries generateSo Li-ion battenies can deliver more powerthan the other battenies of comparable size,leading to ahigher volumetric energy densityamount of energy stoned per mit volumeConstruction of Li-ion batteriesCathode: the electrode Cy it is typically layers ofLi- metal tride (Li CoO2, LiNiO2, LiMn&O4, LINEMnCOO2)Cy Limetal polyatomic materials (LEFEPOY, LiMnPO4,LiFeSOg F).Anode : are electrode make from graphite usuallywith composition Lio.5 C6.Electrolyte Mix of drettys organic carbonates such asethylene carbonate, diethyl carbonate.
