You’re right that both your rechargeable smartphone and an electric car use lithium-ion batteries, and the battery is one of the largest and most costly components inside of an electric car.
The exact size of the battery is going to depend on what type of car you’re looking at, but on average they weigh about 900-1,000 lbs.
The capacity of electric batteries ranges from about 30kWH up to 100kWh, and the size and weight depends on the battery capacity. The Tesla Model S for example contains an 85 kWh battery pack that weighs 1,200 lbs. The battery pack in a 40 kWh Nissan Leaf on the other hand only weighs about 668 lbs and has the external dimensions of 1547 x 1188 x 264 mm.
