Jiang Energy Storage Low Temperature Lithium Battery

Are rechargeable lithium-based batteries a good energy storage device?

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.

Are lithium-based batteries stable at low temperatures?

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.

Do lithium-ion batteries deteriorate in low-temperature environments?

Lithium-ion batteries (LIBs) are widely used as energy units in electric vehicles (EVs), energy storage systems (ESSs), and electronic products [1, 2]. However, the performance of LIBs deteriorates severely in low-temperature environments.

Can interfacial strategies improve performance of Li metal batteries at 15 °C?

In this work, we have demonstrated an interfacial strategy that enables superior performance of Li metal batteries at −15 °C. An EAM was used to alter the SEI structure and Li nucleation at low temperatures and in a carbonate electrolyte.

Are lithium-ion batteries a non-destructive bidirectional pulse current heating framework?

The poor low-temperature performance of lithium-ion batteries (LIBs) significantly impedes the widespread adoption of electric vehicles (EVs) and energy storage systems (ESSs) in cold regions. In this paper, a non-destructive bidirectional pulse current (BPC) heating framework considering different BPC parameters is proposed.

Which lithium-ion batteries have high coulombic efficiency?

LiMn 2 O 4 /Li 4 Ti 5 O 12 lithium-ion batteries containing developed electrolyte demonstrated high Coulombic efficiency (99.8%) for thousands of cycles at room temperature, and remain operational at -50 °C, far outperforming the counterparts using non-aqueous or aqueous electrolytes.
