High-Temperature Lithium Batteries in Extreme Environments
High-Temperature Lithium Batteries in Extreme Environments
In the evolving landscape of battery technologies, lithium batteries have emerged as a preeminent choice for a wide range of applications, from consumer electronics to industrial equipment. However, traditional lithium-ion batteries, including rechargeable polymer lithium-ion batteries and non-rechargeable lithium thionyl chloride battery and lithium manganese dioxide batteries, have their limitations in terms of operating temperature. Specifically, the working temperature range for rechargeable polymer lithium-ion batteries is typically between -20°C and 70°C, while non-rechargeable lithium batteries can operate within a broader range of -50°C to 85°C. Beyond these temperatures, the performance and safety of these batteries are significantly compromised.
When exposed to excessively high temperatures, lithium-based batteries undergo several unfavorable changes. Firstly, the battery capacity and discharge current are negatively impacted, leading to reduced performance. Secondly, the chemical structure of the battery's internal materials undergoes degradation, further diminishing its effectiveness. These changes not only shorten the battery's lifespan but also pose serious safety risks. Therefore, the development of batteries that can withstand extreme temperatures, especially high temperatures, has become a pressing need in certain industries.
Against this backdrop, SER Company has pioneered the production of high-temperature lithium batteries that can endure temperatures up to 200°C. This remarkable feat represents a significant leap forward in battery technology, particularly for applications that require continuous power supply in harsh environments. Let's delve deeper into the advancements of these high-temperature lithium batteries, their unique features, and their potential applications.
Advancements in High-Temperature Lithium Batteries
The core of SER's high-temperature lithium batteries lies in the innovative materials and design that enable them to function effectively at temperatures far exceeding the capabilities of traditional lithium-based batteries. The electrolyte, which is responsible for carrying ions between the anode and cathode during charging and discharging, is a crucial component that undergoes significant modifications. In high-temperature lithium batteries, specialized electrolytes with high thermal stability and low vapor pressure are employed to prevent evaporation and maintain performance even at elevated temperatures.
Furthermore, the electrodes, both anode and cathode, are also designed to withstand the rigors of high-temperature operation. Advanced materials with high chemical stability and low reactivity with the electrolyte are used to ensure that the battery remains stable and efficient at extreme temperatures. The battery's packaging and sealing mechanisms are also enhanced to prevent any leakage or damage due to thermal expansion.
The integration of these advancements results in a battery that can maintain its performance and safety at temperatures up to 200°C. This opens up a vast range of new applications for lithium-based batteries, especially in industries that operate in harsh environments where traditional batteries fail to meet the requirements.
