Why the EV battery life cycle is more important than the battery life

Just like the rechargeable batteries in your toothbrush, camera or mobile phone, batteries in electric vehicles (EVs) don’t last forever. After a few thousand charging cycles, the performance of a typical EV lithium ion (li-ion) battery pack is no longer up to the task of powering the vehicle and must be exchanged for a new one. But, this isn’t the end of the battery; with the right systems and markets in place, these apparently spent batteries can go on to enjoy second, third and even fourth lives in less-demanding uses.
