Lithium ion battery costs: materials and manufacturing?
…cells. It is not that the cells are heavier, but that LFP batteries run at 3.2V, versus others at 3.6V. Although some evidence also suggests LFP cells have lower battery…
Grid-scale battery costs: $/kW or $/kWh?
…to rapidly add MW, then the grid is going to fall over. This is why we care predominantly about batteries producing MW. https://thundersaidenergy.com/2022/09/01/solar-volatility-tell-me-lies-tell-me-sweet-little-lies/ https://thundersaidenergy.com/2021/06/24/power-grids-hell-is-a-hot-still-summers-day/ Grid-scale batteries will tend to minimize…
Energy costs of lithium ion batteries?
This data-file estimates the energy costs of lithium ion batteries across 17 lines. Our best estimate in 2024 is that manufacturing 1 kWh of lithium ion batteries requires 175 kWh…
Renewables plus batteries: co-deployments over time?
…different battery chemistries — lead-acid, sodium-sulphide — rather than today’s projects that are predominantly LFP lithium ion. The duration of these grid-scale batteries has also increased from 2.6 hours prior…
Good Batteries vs Bad Batteries?
…plus batteries can achieve a c2x efficiency uplift. Additional opportunities are emerging to uplift system efficiency using batteries. One recent example was described by ConocoPhillips, at the Darwin LNG plant,…
Energy storage: top conclusions into batteries?
…(8) Next-gen batteries: can we de-risk them? There is constant progress and innovation in batteries, to improve density, duration, chemistry, longevity, cost, charging speeds. So we are constantly screening patent…
Battery degradation: what causes capacity fade?
…lithium ion batteries are using LFP chemistry, charging within a limited range, at low charge-discharge rates (C-rates) at a stable temperature of around 25C. This might be associated with a…
Redox flow batteries: for the duration?
Redox flow batteries have 6-24 hour durations and require 15-20c/kWh storage spreads. They will increasingly compete with lithium ion batteries in grid-scale storage. Does this unlock a step-change for peak…
Lithium ion batteries: energy density?
Today’s lithium ion batteries have an energy density of 200-300 Wh/kg. I.e., they contain 4kg of material per kWh of energy storage. Technology gains can see lithium ion batteries’ energy…
Battle of the batteries: EVs vs grid storage?
Who will ‘win’ the intensifying competition for finite lithium ion batteries, in a world that is hindered by shortages of lithium, graphite, nickel and cobalt in 2022-25? Today’s note argues…
