Cell Energy Density Roadmap to 2035

Keep getting asked about cell energy roadmaps and wanted to put this in context, hence using our cell database to set the scene and then walk out to 2035.

How the charts were built

  • The year for each cell is its start of production. Where a pre-production cell has no production date, we used the year it was announced.
  • A cell counts as production if it is a C or D sample, or has no sample level recorded, and is dated 2026 or earlier. Pre-A, A and B samples and anything dated after 2026 are shown as pre-production. The cell sample maturity page explains the A to D levels.
  • The best-cell line for each chemistry is the highest value reached by any production cell up to that year, so it only ever rises.
  • Four groups: graphite or silicon-blend NMC, NCA, NCMA and LCO; LFP and LMFP; sodium-ion; and next-gen EV-format, which covers semi-solid, solid-state and lithium-metal cells from automotive programmes. Drone and aviation cells using the same chemistries are plotted as a separate dotted line and are not projected.
  • Seven rows were left out because the numbers cannot be right for the stated chemistry, for example LFP cells listed at close to 900 Wh/L. They are being checked in the database.

9.7 kWh sodium-ion home battery promises ultra-long 20,000-cycle life at 100% discharge.

Home energy storage is being revamped. The 48 V residential energy storage system (RESS) developed by AuroraCell, a Bulgaria-based company, uses sodium-ion chromium oxide (NCO) cathode technology.

100,000,000 homes could be powered by solar projects stuck in permitting

Dig deep into every US energy project stuck in permitting and the utility companies that own them.

When do we anticipate solid-state batteries to hit consumer markets for home backup?

What the title says. Looking to store excess from my solar into a 3-6 Kwh battery systems and don't want to invest thousands into a chemical that can burn down a house in an instant.

Edit: Thank you everyone for the responses. What I gather from the comments, its either LFP or sodium-ion one for home battery usage.

Qnetic: The Future of Energy Storage. Do the physics work on this?

This is a Kinetic energy storage (KESS), also called Flywheel (FESS)

The idea is very old, variations already in use today.

The question is this design is uses a carbon fiber cylinder about 3~4 ft (~1m) in diameter, yet states they can provide 1000 kWh of energy storage, magnitudes more than others. THAT is what I am suspicious about.

Comparisons:

  • Beacon Gen4. 25 kWh. 15 minutes of discharge
  • Amber Kinetics M32. 32 kWh. 4 hours of discharge
  • QNETIC: Q1. 1,000 kWh. 4 to 12 hours of discharge, design target

Massively more energy storage, using a less dense mass. The density of carbon varies depending on its form, but typically ranges from 1.5 to 2.1 g/cm³, while iron has a density of about 7.87 g/cm³.

Is this too fantastic, or possible to get close?
