Four types of advanced batteries could reportedly be nearing readiness for electrified vehicle and energy storage markets.
While lithium-ion (Li-ion), advanced lead-acid, flow, and molten salt batteries have become the most commercially available advanced batteries, there are better battery technologies waiting in the wings, according to a study by Navigant Research. Lithium sulfur (Li-S), lithium solid-state (Li-SS), next-generation flow, and a liquid metal battery are at the level of laboratory-scale research or pilot-scale production levels today.
Li-ion is currently the primary chemistry used for transportation and grid-tied stationary energy storage applications that require next-generation batteries. There will be limitations to Li-ion over time, including challenges related to energy density, safety, and costs, Navigant Research says.
Li-S, Li-SS, next-generation flow, and other advanced batteries could be contenders encroaching on Li-ion’s market share as the world’s most flexible battery chemistry in the transportation and stationary energy storage sectors. The rite of passage for the new battery technologies will be meeting and exceeding the safety expectation of Li-ion batteries at lower price points, the study says.
The demand for, and usage of, advanced batteries for transportation and energy storage is expected to increase substantially. Navigant Research anticipates that the global energy capacity for next-generation advanced batteries is expected to grow from 30.2 megawatt hours (MWh) in 2019 to 6.5 gigawatt hours (GWh) annually in 2025.
Automakers are analyzing their options in next-gen battery technologies for 200-mile electric cars and energy storage systems. BMW recently joined Tesla, Daimler, and Nissan in the energy storage market.
