lithium thionyl chloride

Lithium thionyl chloride batteries represent a cutting-edge primary battery technology that combines lithium metal as the anode with thionyl chloride as the cathode and electrolyte. These batteries are engineered to deliver exceptional performance characteristics, including high energy density, superior voltage stability, and remarkable longevity. With an impressive operating voltage of 3.6V and energy densities reaching up to 1280 Wh/kg, these power solutions stand out in the battery market. Their unique chemistry enables them to maintain stable voltage throughout their discharge cycle, ensuring consistent power delivery until depletion. These batteries excel in extreme temperature conditions, operating effectively from -55°C to +85°C, making them ideal for demanding industrial and military applications. The hermetically sealed construction prevents leakage and ensures safety, while their low self-discharge rate of less than 1% per year guarantees reliable long-term performance. These characteristics make lithium thionyl chloride batteries particularly suitable for remote sensing equipment, military devices, medical instruments, and industrial automation systems where consistent, long-term power supply is crucial.

New Products

Lithium thionyl chloride batteries offer numerous compelling advantages that set them apart in the power solution market. First, their exceptional energy density provides more power in a compact size, enabling the design of smaller, more efficient devices. The remarkably low self-discharge rate ensures that devices remain powered for extended periods, often exceeding 10 years in normal conditions. These batteries maintain stable voltage throughout their operational life, eliminating the need for voltage regulation in many applications. Their wide temperature tolerance makes them ideal for both extreme cold and hot environments, ensuring reliable performance where other battery technologies fail. The hermetic sealing technology prevents leakage and contamination, ensuring safe operation in sensitive environments. Their ability to handle high pulse currents when paired with hybrid layer capacitors makes them suitable for applications requiring burst transmission capabilities. The absence of maintenance requirements reduces total ownership costs, while their long shelf life of up to 10 years provides flexibility in inventory management. These batteries are also environmentally conscious, with minimal toxic materials and excellent safety records. Their reliability in critical applications has made them the preferred choice for medical devices, military equipment, and industrial monitoring systems where failure is not an option.

Unmatched Longevity and Reliability

Unmatched Longevity and Reliability

The exceptional longevity of lithium thionyl chloride batteries stems from their sophisticated chemistry and construction. Their self-discharge rate of less than 1% per year significantly outperforms other battery technologies, enabling operational lifespans exceeding a decade under normal conditions. This remarkable stability is achieved through a passivation layer that forms on the lithium anode, protecting it from degradation while allowing normal discharge when required. The hermetic sealing technology prevents environmental contamination and ensures consistent performance throughout the battery's life. This long-term reliability is particularly valuable in remote or hard-to-access installations, reducing maintenance costs and system downtime. The combination of extended shelf life and operational life makes these batteries ideal for emergency systems and backup power applications where immediate readiness is crucial.
Superior Performance in Extreme Conditions

Superior Performance in Extreme Conditions

Lithium thionyl chloride batteries demonstrate exceptional resilience in extreme environments, maintaining consistent performance across a wide temperature range from -55°C to +85°C. This thermal stability is achieved through their unique chemical composition and specialized manufacturing processes. The non-aqueous electrolyte prevents freezing in sub-zero temperatures while maintaining stable ionic conductivity at high temperatures. This wide operating range makes these batteries ideal for outdoor installations, arctic research equipment, and desert-based monitoring systems. The batteries maintain their voltage stability and capacity even under these challenging conditions, ensuring reliable operation where other power solutions would fail. This characteristic is particularly valuable in critical applications where environmental conditions are unpredictable or extreme.
High Energy Density and Power Efficiency

High Energy Density and Power Efficiency

The high energy density of lithium thionyl chloride batteries, reaching up to 1280 Wh/kg, represents a significant advancement in power solution technology. This exceptional energy-to-weight ratio enables the design of compact, lightweight devices without compromising power capacity. The high nominal voltage of 3.6V reduces the need for multiple cells in series, simplifying device design and improving reliability. When combined with hybrid layer capacitors, these batteries can deliver high pulse currents while maintaining their long-term stability. This efficient power delivery system makes them ideal for applications requiring both sustained low-power operation and occasional high-power bursts, such as wireless sensors and tracking devices. The high energy density also translates to reduced size and weight, crucial for portable equipment and space-constrained installations.
