Are solid state batteries the future of energy storage?

FutureBatteryLab Cost of solid state batteries: Expensive premium solution or affordable all-rounder? 22. December 2022 Solid-state batteries are being touted as the energy storage devices of tomorrow and are expected to find widespread use in a few years – from electric cars to airplanes.

How much does a lithium battery cost?

Schmuch et al. evaluate the cost of batteries with liquid electrolytes and graphite anode at about $58 per kWh. For solid-state batteries, they differentiate depending on the anode: with a 20% excess of lithium in the lithium metal anode, they calculate a price of about $75 per kWh; with a 300% excess, they determine a price of 128 kWh per kWh .

Are solid-state batteries a promising future for lithium-ion batteries?

The data used in this article comes from the BEMA2020 research project, which is funded by the German Federal Ministry of Education and Research (grant number 03XP0272B). Solid-state batteries are regarded as a promising further development of lithium-ion batteries.

How much will a solid-state battery cost in 2026?

For the ramp-up phase of solid-state batteries, there is also already a forecast of costs: in a study conducted in 2019, CISION PR Newswire estimates the cost at $400-800 per kWh in 2026 , which is four to eight times higher than current battery systems. But how do things look beyond these scaling effects?

Are solid-state batteries the next major development step?

Solid-state batteries (SSB, Figure 1b) promise higher energy densities and improved safety compared to liquid electrolyte LIB and could therefore represent the next major development step.

Are solid-state batteries competitive compared to liquid electrolyte Lib?

Strong R&D activities, fueled by great interest from the automotive sector in particular, suggest that these challenges can be solved. Ultimately, however, solid-state batteries will have to prove their competitiveness compared to liquid electrolyte LIB on the market, particularly in terms of cost, energy and power density.
