Temperature Affects Safety of Lithium-Ion Batteries

Room temperatures can directly affect the temperature inside the lithium-ion battery, affecting how safe the battery is and how it performs. Freshliance COEUS-WIFI wireless temperature logger adopts IoT technology, which can monitor room temperature 7/24 to avoid the risk of high temperature sparking lithium-ion batteries explosion accident.

Lithium-ion batteries can power devices, equipment, vehicles, and new technologies. Lithium-ion batteries operate through the movement of ions between the positive and negative electrodes. When the battery discharges, the negative electrode moves through the electrolyte to the positive electrode. The process is then reversed when the lithium-ion battery is recharged. During this complex process, many factors can decrease the battery's performance and safety. The ambient temperature of the battery storage area can adversely affect the stability of the battery cell. Understanding how ambient temperature can affect the safety and performance of the battery and knowing how to keep the room temperature at an ideal level would be beneficial for your handling and storage practices on lithium-ion batteries.  

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. If conditions are too hot, it can result in hazards such as fire and explosion. Just like any type of hazardous chemical or substance, it’s vital that you always read and follow the manufacturer’s instructions when handling, charging and storing your lithium-ion batteries. Keeping batteries at a safe temperature can be difficult in a hot environment. That’s why it’s crucial to consider storage options that include temperature monitoring measures that can monitor humidity and heat.

As you’ve learned, excessively high temperature can cause serious safety issues for lithium-ion batteries. Getting the right wifi temperature logger can help with that. The Freshliance COEUX-WIFI wireless temperature and humidity sensor can be placed in the battery storage room to display the temperature and humidity in real-time. Multiple wireless temperature and humidity monitor, gateway and platform constitute the wireless monitoring system. Gateway will receive all sensing data, and then it forwards all data to Freshliance Cloud. Users can not only see visualized data on mobile phone but also get real-time alarms from anywhere. The system continuously monitors the temperature and gives pinpoint accurate alerts/ local indications through the app to find the abnormal status. It sends real-time emails or SMS alerts, LED indications and 70dB audible alarms to ensure lithium-ion batteries can be stored in the right condition.
