This is partly due to the low cost of the raw materials necessary to make the battery. And as these batteries continue to grow in mass production, the cost of manufacturing continues to get cheaper as well. Battaglia said the large volumes at which these batteries are produced have cut the costs quite a bit. But it wasn't always this cheap.
Corporations and universities are rushing to develop new manufacturing processes to cut the cost and reduce the environmental impact of building batteries worldwide.
"There is a need for materials that can store a large amount of lithium, sodium and magnesium for use in high-performance batteries," says Detsi. "The problem is that the more lithium, sodium or magnesium a battery material can store, the more it expands and shrinks during charging and discharging, resulting in huge volume change."
This suggests that the owner of a typical EV may not need to replace the expensive battery pack or buy a new car for several additional years. Almost always, battery scientists and engineers have tested the cycle lives of new battery designs in laboratories using a constant rate of discharge followed by recharging.
While battery prices have plummeted about 90% over the past 15 years, batteries still account for almost a third of the price of a new EV. So, current and future EV commuters may be happy to learn that many extra miles await them.
Solid-state batteries are safer, lighter and potentially cheaper and offer longer performance and faster charging than current batteries relying on liquid electrolytes. Breakthroughs in consumer electronics have filtered through to electric vehicles, although the dominant battery chemistries for the two categories now differ substantially.

What are Eneloop batteries? 35 Frequently asked questions
The Pro cells have thinner canisters and separators, allowing for more active material and electrolyte. The reason for a difference in cycle life is related to the ratio of positive and negative electrode material: the higher the ratio, the better the cycle life. With Eneloop Lite being on the opposite end of the Eneloop Pro, you can see the relation: https://main.panasonic …
