Good practices for rechargeable lithium metal batteries

Are lithium metal batteries safe?

Both the safety and lifespan of lithium metal batteries are rooted in the pulverization of Li metal. 4, 6 Although many solutions have been proposed to enable a stable cycling of lithium metal anode, much less attention has been paid to mitigating the safety risks of doing research on high-energy cells (lithium ion or lithium metal cells).

Are high-energy lithium metal batteries safe?

Possible scenarios that may raise safety concern have been considered and discussed through the entire research cycle of high-energy lithium metal batteries. Accordingly, safety plan has been proposed for each stage of research and only used as best practice for research purpose.

Could rechargeable lithium metal batteries double the energy of lithium-ion batteries?

Rechargeable lithium metal batteries could potentially double the cell-level energy of state-of-the-art lithium-ion batteries (LIBs). 1 It has been considered as one of the most promising next-generation battery technologies for electric vehicles with increased driving mileage and reduced cost.

Should lithium metal-based batteries be standardized?

It remains important to develop standardized protocols for material and cell characterization, cycling performance, safety, and recycling procedures for lithium metal-based batteries.

Are lithium metal rechargeable batteries the future of electric vehicles?

As lithium metal rechargeable batteries continue to be studied, their widespread adoption in electric vehicles remains around the corner.

Can a power-controlled discharge testing protocol reveal lithium metal battery dynamics?

We introduce a power-controlled discharge testing protocol for research and development cells, in alignment between major automotive stakeholders, that may reveal lithium metal battery dynamics closer to practical driving behavior.
