The power-to-weight ratio of a battery can be increased by reducing its weight or increasing its sustainable power output. Moreover, energy output can be obtained with higher energy density. It will lead to smaller, lighter, and longer-lasting batteries.
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.
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.
The first step in calculating the weight of a lithium ion battery pack is to determine its capacity in amp-hours (Ah). This is typically provided by the product specification for off-the-shelf batteries or by dividing the total energy (in Watt-hours) by the nominal voltage if designing custom packs.
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.
For example, lithium-ion batteries have high energy density. It has lighter weight characteristics. Moreover, in comparison with lead acid batteries, they have lower energy density. They are also heavier in weight. 6. Battery Safety
