Megawatt lithium second-life battery energy storage

Can Second-Life Electric Vehicle batteries improve energy security and the circular economy?

How second-life electric vehicle (EV) batteries can enhance energy security and the circular economy. Globally, battery energy storage is a rapidly growing segment of the power industry. Battery energy storage systems (BESS) are valued for their capabilities on microgrids right through to utility-scale applications.

Should EV batteries be Second-Life?

The three main pillars of the argument in favor of second-life BESS are performance, energy security, and the circular economy. Performance. EV batteries degrade over time. However, when an EV reaches the end of its life, the batteries typically still have up to 80% of their original energy storage capabilities.

How much CO2 does a second life battery save?

For example, 800 million pounds amounts to about 40.8 GWh of second-life battery capacity. Assuming that even 25% of these batteries are reusable, that would deliver estimated savings of 816,000 tonnes of CO 2 compared to using first life batteries.

Are second-life batteries a cost advantage?

We estimate that, at current learning rates, the 30 to 70 percent cost advantage that second-life batteries are likely to demonstrate in the mid-2020s could drop to around 25 percent by 2040. This cost gap needs to remain sufficiently large to warrant the performance limitations of second-life batteries relative to new alternatives.

How much energy does a lithium ion battery use?

The lithium-ion batteries of the system under test have a remaining usable energy between 75 % and 90 %, depending on the type of lithium-ion battery, while the usable energy of the lead acid batteries is only 60 %.

What is battery energy storage?

Battery energy storage provides the control mechanism to give the grid resilience by balancing energy demand with generation. But the batteries for these BESS—or the components and materials within them—are still predominantly coming from outside of North America and Europe.
