The impact of storage temperature on lithium batteries

How does lithium ion battery storage temperature affect battery performance?

In the simplest of terms, the lithium ion battery storage temperature has a direct effect on the chemical reaction within the battery cell. Very low temperatures can produce a reduction in the energy and power capabilities of lithium-ion batteries.

Does short-term storage affect the thermal stability of lithium-ion batteries?

In practical applications, lithium-ion batteries inevitably encounter short-term exposure to high or low temperatures due to geographical climate variations and specific usage scenarios. This study explored the impact of short-term storage at temperatures ranging from −40 to 60 °C on the thermal stability of batteries.

What temperature should a lithium ion battery be stored?

Lithium-ion batteries should be ideally stored in cool, dry conditions at a temperature of 15°C. The general temperature range for lithium-ion cells lies between 5°C and 20°C. If temperatures are too cold, such as 0°C, it can result in a loss of capacity due to the chemical reactions inside the battery slowing down due to the low temperature.

How does high temperature storage affect battery chemistry?

The high temperature storage can cause various changes in battery chemistry, including particle cracking of the cathode, thickening of the SEI/CEI layer, the production of unstable organic byproducts, resistance growth, etc., all of which contribute to the reduced thermal stability of batteries [38, 46, 47].

Do lithium-ion batteries Burn After long-term high-temperature storage?

Wang investigated the combustion characteristics of lithium-ion batteries following long-term high-temperature storage caused by external heating abuse. The results demonstrate a reduction in the maximum flame temperature, flame height, and combustion intensity during the TR of batteries after long-term storage at high temperatures.

How does lithium plating affect battery life?

Lithium plating is a specific effect that occurs on the surface of graphite and other carbon-based anodes, which leads to the loss of capacity at low temperatures. High temperature conditions accelerate the thermal aging and may shorten the lifetime of LIBs. Heat generation within the batteries is another considerable factor at high temperatures.
