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% [4].

3 天之前· Lead-acid batteries degrade rapidly in extreme temperatures, losing up to 50% of their capacity in hot climates, while AGM batteries, though longer-lasting than standard lead-acid, still face reduced efficiency and shorter cycle life under harsh conditions. In contrast, WattCycle''s LiFePO4 lithium batteries deliver superior efficiency across a wide temperature range and
Active Thermal Management: Some battery systems designed for harsh environments come with built-in heating elements that automatically warm the battery to an optimal temperature. How to Charge Lithium Batteries in Cold Weather? Charging lithium-ion batteries in cold temperatures is more delicate than discharging them. At temperatures below
The lead acid battery works well at cold temperatures and is superior to lithium-ion when operating in subzero conditions. According to RWTH, Aachen, Germany (2018), the cost of the flooded lead acid is about $150 per kWh, one of the lowest in batteries. Sealed Lead Acid. The first sealed, or maintenance-free, lead acid emerged in the mid-1970s. Engineers argued that
Capacity. A battery''s capacity measures how much energy can be stored (and eventually discharged) by the battery. While capacity numbers vary between battery models and manufacturers, lithium-ion battery technology has been well-proven to have a significantly higher energy density than lead acid batteries.

When Gaston Planté invented the lead–acid battery more than 160 years ago, he could not have foreseen it spurring a multibillion-dollar industry. Despite an apparently low energy density—30 to 40% of the theoretical limit versus 90% for lithium-ion batteries (LIBs)—lead–acid batteries are made from abundant low-cost materials and nonflammable

However, the low-temperature Li metal batteries suffer from dendrite formation and dead Li resulting from uneven Li behaviors of flux with huge desolvation/diffusion barriers, thus leading to short lifespan and safety concern. Herein, differing from

Until now, much work has been done to probe the influence of low temperature on LIBs. 6–12 Ling et al.6 cycled batteries under ambient temperatures of −10 and 5 °C, respectively; their results showed that the low temperature environment harmed the battery performance, reducing the discharging voltage and accelerating the capacity decay.
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% .
In general, from the perspective of cell design, the methods of improving the low-temperature properties of LIBs include battery structure optimization, electrode optimization, electrolyte material optimization, etc. These can increase the reaction kinetics and the upper limit of the working capacity of cells.
However, faced with diverse scenarios and harsh working conditions (e.g., low temperature), the successful operation of batteries suffers great challenges. At low temperature, the increased viscosity of electrolyte leads to the poor wetting of batteries and sluggish transportation of Li-ion (Li +) in bulk electrolyte.
However, the low-temperature Li metal batteries suffer from dendrite formation and dead Li resulting from uneven Li behaviors of flux with huge desolvation/diffusion barriers, thus leading to short lifespan and safety concern.
In short, the design of electrolytes, including aqueous electrolytes, solid electrolytes, ionic liquid electrolytes, and organic electrolytes, has a considerable improvement in the discharge capacity of lithium-ion batteries at low temperatures and greatly extends the use time of batteries at low temperatures.
