Currently Lithium-Ion (Li-Ion) batteries are pretty ubiquitous in the rapidly growing electric vehicle (EV) and battery energy storage system (BESS) markets. However, that does not preclude advancements in chemistry or manufacturing technology from substantially lowering the price of these batteries. This also applies to an alternative chemistry that is a close relative of Li-Ion.
One of the primary strategies to reduce climate change (a.k.a. global warming) is conversion of processes that produce greenhouse gasses, the primary causes of climate change, with processes that only use electric energy produced by zero-GHG generation. There are currently many electric-generation technologies that produce little or no GHG in operation, but some are intermittent. BESS is an important part of combatting climate change as these intermittent renewables are also the least expensive types of generation, and BESS can reduce or eliminate their intermittency.
Although there are currently many processes that produce GHG, some of the main ones are in mobility technology, especially those that use GHG-producing fuel (a large majority of current road, rail, air and marine transportation technologies). Rechargeable batteries are a key technology in many of the segments of the electric vehicle market that will displace current GHG-emitting vehicles.
