Chicago-headquartered NanoGraf Technologies, which claims it has enabled the highest energy-density cylindrical 18650 Lithium-ion cell in the world, today announced that its battery has achieved a new industry energy-density milestone of 810 Wh/L (4.0Ah capacity).
Ampirus has shipped the first batch of what it calls the most energy-dense lithium batteries available today. These silicon anode cells hold 73 percent more energy than Tesla's Model 3 cells by weight, and take up 37 percent less volume.
This limits their operational visibility. Overall, this means that total battery energy storage capacity in Great Britain stood at 3.7 GW at the end of 2023. The 184 MW of new capacity in Q1 2024 means that the total capacity at the end of the quarter was 3.9 GW.
Shaniyaa looks into the buildout of battery energy storage in Q1 2024. 184 MW of new capacity becoming operational in Q1 2024, the lowest since Q3 2022. The new capacity came from six new battery energy storage units. These range from 19 MW to 50 MW in rated power and one to two hours in duration.
The battery tested at 711.3 Wh/kg, and it also offered an exceptional volumetric energy density of 1,653.65 Wh/liter. Naturally, it's just a research-grade lab cell, and a long way off any form of commercialization.
We previously reported that the highest-ever new capacity in a single quarter was 420 MW in Q4 2023. However, Gresham House’s Trading Update in February stated that the 50 MW West Didsbury battery had begun commercial operation in December 2023. This means 470 MW of new capacity actually became commercially operational in Q4 2023.
