With lithium-ion batteries powering devices, equipment, vehicles and new technologies, it’s important to understand how ambient temperature can affect the safety and performance of the battery. Room temperatures can directly affect the temperature inside the lithium-ion battery — and this will affect how safe the battery is and how it performs.
Lithium-ion batteries operate through the movement of ions between the positive and negative electrodes. When the battery is discharging, the negative electrode moves through the electrolyte to the positive electrode. The process is then reversed when the lithium-ion battery is being recharged. During this complex process, many factors can decrease the battery performance and its safety. The ambient temperature of the battery storage area —as well as li ion battery handling and charging or discharging practices — can all adversely affect the stability of the battery cell.
Therefore, batteries should be handled in accordance with the manufacturer’s specifications. You should pay attention to the instructions regarding the safe limits for maximum current load, charging, and end-point voltages and so on.
