Lithium-ion cells can have incredible cycle (>10,000) and calendar lives (>40 years). I will explain how such long-lived cells can be made. The common belief is that only 800 charge-discharge cycles is enough for EVs so why do we need such amazing cells? Ninety percent of all Li-ion cells produced in 2030 will be used in EVs, so vehicle to grid storage is absolutely required to incorporate more renewables on the grid to reduce dependency on fossil fuels. Such awesome Li-ion cells are needed so EV batteries can support a large fraction of their charge-discharge cycles while parked.
