Panasonic could start mass producing larger-capacity batteries for Tesla as soon as next year. The 4680 cell is said to boost the range of electric vehicles by over 15 percent. As Nikkei notes, that could boost the range of the Model S from 650km (404 miles or so) on a single charge to 750km (around 465 miles).

Although the battery is said to be twice as big as previous versions, it has a fivefold increase in energy capacity, according to Nikkei. As such, cars need fewer of the batteries, which are already 10 to 20 percent cheaper to produce. It's estimated that batteries account for 30 percent of the cost of EVs. A cost reduction could make EVs more affordable and hasten the transition to electric vehicles. What's more, a longer range means drivers won't need to charge batteries as often.
