lithium thionyl chloride battery
Lithium thionyl chloride batteries represent a sophisticated power solution that combines high energy density with exceptional longevity. These primary batteries utilize lithium metal as the anode material and thionyl chloride as both the cathode material and electrolyte, creating a unique and highly efficient electrochemical system. The battery's construction features a hermetically sealed design that prevents leakage and ensures stable performance across diverse environmental conditions. With a nominal voltage of 3.6V, these batteries deliver consistent power output throughout their operational life, maintaining stable voltage levels until near complete discharge. Their self-discharge rate is remarkably low, typically less than 1% per year under normal conditions, which contributes to their impressive shelf life of up to 20 years. The technology excels in applications requiring long-term reliable power, particularly in remote or hard-to-access locations. These batteries find extensive use in utility metering, industrial monitoring systems, military equipment, medical devices, and various IoT applications where frequent battery replacement is impractical or cost-prohibitive. Their ability to operate effectively across a wide temperature range, from -55°C to +85°C, makes them particularly valuable for outdoor and extreme environment applications.
