Portonovo energy storage low temperature lithium battery

Stable operation of rechargeable lithium-based batteries at low temperatures is important for cold-climate applications, but is plagued by dendritic Li plating and unstable solid–electrolyte interphase (SEI). Here, we report on high-performance Li metal batteries under low-temperature and high-rate-charging conditions.

In this article, a brief overview of the challenges in developing lithium-ion batteries for low-temperature use is provided, and then an array of nascent battery chemistries are introduced that may be intrinsically better suited for low-temperature conditions moving forward.

Specifically, the prospects of using lithium-metal, lithium-sulfur, and dual-ion batteries for performance-critical low-temperature applications are evaluated. These three chemistries are presented as prototypical examples of how the conventional low-temperature charge-transfer resistances can be overcome.

Rechargeable lithium-based batteries have become one of the most important energy storage devices 1, 2. The batteries function reliably at room temperature but display dramatically reduced energy, power, and cycle life at low temperatures (below −10 °C) 3, 4, 5, 6, 7, which limit the battery use in cold climates 8, 9.

Consequently, dendrite-free Li deposition was achieved, Li anodes were cycled in a stable manner over a wide temperature range, from −60 °C to 45 °C, and Li metal battery cells showed long cycle lives at −15 °C with a recharge time of 45 min. Our findings open up a promising avenue in the development of low-temperature rechargeable batteries.

LIBs can store energy and operate well in the standard temperature range of 20–60 °C, but performance significantly degrades when the temperature drops below zero [2, 3]. The most frost-resistant batteries operate at temperatures as low as −40 °C, but their capacity decreases to about 12% .
