Batteries are widely used in various industries. Besides the batteries are requested to work in high-temperature environments, especially in extremely hot areas. When the batteries work at high temp environments, it will bring some risk to batteries and affect the performance. When the batteries work at a temperature over 60 °C, it is called high temperature environment. When the batteries work over 60°C, we should some actions to reduce the temperature or boost the batteries’ high temperature resistance.
This article will provide you with an in-depth discussion of the various types and unique characteristics of high temperature batteries, especially as compared to normal Li-ion batteries. In addition, we are going to look at a few intriguing options for developing high temperature battery packs.
The Classification of High Temp Battery
High temperature batteries, also known as high-temperature rechargeable batteries, are designed to work well in cold temperatures. They are included in the following three types.
High Lipo Battery
The lipo battery can support work at no higher than 80°C. When your devices choose lipo batteries, the space in your devices for lipo batteries is limited. That means the lipo cells should support the high-temperature environments.
High-Temperature Lithium-ion Battery
The high-temperature lithium-ion battery can support 85°C with long cycles. This type of high-temperature lithium-ion battery is widely used for outdoor GPS for cars & trucks.
Custom High-Temperature Battery Pack
The custom high-temperature battery packs are made of normal lithium-ion battery cells. But we usually adopt the technology by adding the cooling water, and heat insulation to protect the battery pack. This type batteries can be used for drilling, and mine exploration machines.
What Is The Difference Between High-Temperature Li-ion Battery and Normal Li-ion Battery?
High-temperature li-ion batteries differ from normal li-ion batteries in several ways. Understanding these differences is critical for effective application in high-temperature environments.
Higher Capacity Retention
When the high temperature lithium battery is at 85°C, the capacity retention reaches 90%.

Internal Resistance Stability
The high temperature li-ion battery has stable internal resistance stability when the batteries work over 60°C.
Longer Cycles
The high temperature battery has longer cycles and 500 cycles 90% capacity left.
