Electric vehicle batteries has come a long way since the first electric vehicles were invented in the 1830s. Modern electric vehicles run on lithium-ion batteries, which were introduced in 1991.
As the EV battery and energy storage markets grow, manufacturers continue to experiment with chemistries, configurations, and production processes—with the common goal of creating more efficient batteries that last longer, cost less, and have a lower environmental impact. What goes into an EV battery is already changing and is likely to continue to change over the next decades.
What Is in an EV Battery?
An EV battery is a pack of individual battery cells, each about the size of a AA battery. Those cells are clustered into protective frames called modules, each with its own circuitry, and those modules are clustered together into a pack.
The entire pack is managed by a Battery…
