AI Customer ServiceAs the integration of renewable energy sources into the grid intensifies, the efficiency of Battery Energy Storage Systems (BESSs), particularly the energy efficiency of the ubiquitous lithium-ion batteries they employ, is becoming a pivotal factor for energy storage management.
Therefore, even if lithium-ion battery has a high CE, it may not be energy efficient. Energy efficiency, on the other hand, directly evaluates the ratio between the energy used during charging and the energy released during discharging, and is affected by various factors.
Due to the presence of irreversible side reactions in the battery, the CE is always less than 100%. Generally, modern lithium-ion batteries have a CE of at least 99.99% if more than 90% capacity retention is desired after 1000 cycles . However, the coulombic efficiency of a battery cannot be equated with its energy efficiency.
Another pre-sodiation method is mixing the anode material with sodium metal to obtain a sodium-rich composite anode. As the sodium-rich anode can provide partial Na + to compensate the sodium loss in the first cycle, the energy density of full battery can be obviously improved.
For these renewable energy sources to provide a stable, consistent power supply, it is essential that the batteries they rely on can deliver a high level of energy efficiency relative to the energy used to charge them.
With the characteristics of a commercial 3.35 Ah NCA/C+Si battery cell, we determined the SoE (OCV) and experimentally verified that the traditional method underestimates the residual energy significantly for the tested battery cell.
