Today’s lithium ion batteries have an energy density of 200-300 Wh/kg. In other words, there is 4kg of material per kWh of energy storage. Of this material build-up, 2 kg is in the cathode, 1 kg is in the anode, 0.6 kg in the current collectors, 0.3 kg in the electrolyte and 0.1 kg in the balance.
Lithium ion batteries have an energy density of around 160 Wh/kg, which is 0.16 kWh/kg. This 12:0.16 ratio translates to an equivalent volumetric density of 76.8 kWh/l. The Tesla Model S has a battery pack with a capacity of 85 kWh and weighs 540 kg; this gives it a volumetric energy density of 0.39 kWh/l - about 5% of the equivalent for gasoline.
Lithium-ion batteries charge faster, last longer and have a higher power density for more battery life in a lighter package. The weight of a Lithium-ion battery depends on the size, chemistry, and the amount of energy it holds. A typical cell weighs about 30-40 grams. Cells are packaged together to make a battery pack for a device.
Although negative electrodes made of lithium cobalt nickel, for example, allow an energy density of up to 240 watt-hours per kilogram, lithium-ion batteries with around 170 watt-hours per kilogram are used more frequently. Because of the lower energy density, these batteries offer more than 500 charging cycles and are thus more durable overall.
Thus the energy stored (in Joules) can be calculated by multiplying Faraday’s Constant (in Coulombs per mol) by the cell voltage (in Volts) and the number of mols of ions making this journey from anode to cathode (in mols). Today’s lithium ion batteries have an energy density of 200-300 Wh/kg.
A typical lithium-ion battery can generate around 3.6 volts per cell. If you are using a 12 volt lead–acid battery now you will need three lithium-ion batteries to create the same voltage output. Lithium-ion batteries charge faster, last longer and have a higher power density for more battery life in a lighter package.
