Product Overview

The Tadiran TLI‑1550HT is a 4.0V rechargeable lithium‑ion (TLI) cell engineered specifically for high‑temperature industrial IoT, energy‑harvesting systems, and mission‑critical wireless devices that require exceptional cycle life, high pulse capability, and reliable operation in extreme thermal environments. As part of Tadiran’s high‑temperature TLI portfolio, the TLI‑1550HT is designed for continuous‑duty electronics that must survive sustained exposure to elevated temperatures while delivering 10+ years of autonomous performance.

High‑Temperature Industrial Li‑ion Chemistry

The TLI‑1550HT uses Tadiran’s proprietary high‑temperature Li‑ion chemistry, engineered for environments where standard rechargeable lithium cells fail. Key characteristics include:

• 4.0V nominal voltage with stable discharge behavior

• High cycle life, often 5,000+ cycles depending on depth of discharge

• Very low self‑discharge, enabling long standby periods

• Fast recharge acceptance, ideal for energy‑harvesting inputs

• Extended high‑temperature capability, typically up to +125°C depending on configuration

• Long calendar life, often 10+ years in field deployments

This chemistry is optimized for continuous‑use, high‑temperature industrial systems.

Electrical Performance for Harsh‑Environment IoT

The TLI‑1550HT is engineered for low‑average‑current devices that require periodic high‑current pulses for wireless communication, even in elevated temperatures. Electrical advantages include:

• Stable 4.0V output for modern low‑power electronics

• High pulse capability for radio bursts (LoRa, NB‑IoT, BLE, Zigbee, etc.)

• Excellent recharge acceptance from solar, vibration, RF, or thermal harvesters

• Predictable cycling behavior with minimal capacity fade

• Reliable operation in extreme thermal and environmental conditions

This makes the TLI‑1550HT ideal for energy‑harvesting IoT nodes deployed in hot climates, enclosed industrial housings, or high‑heat process environments.

Mechanical and Environmental Durability

The TLI‑1550HT is built for rugged, high‑temperature industrial environments:

• Hermetically sealed stainless‑steel construction

• High resistance to shock, vibration, and mechanical stress

• Excellent performance in extreme heat and cold

• Long shelf life and stable long‑term cycling

• Compact cylindrical form factor for embedded designs

Its durability ensures reliable operation in mission‑critical, remote, and maintenance‑restricted deployments where heat exposure is unavoidable.

Typical Applications

The TLI‑1550HT is widely used in high‑temperature, rechargeable, and energy‑harvesting IoT systems, including:

• Industrial IoT nodes in high‑heat environments

• Oil & gas instrumentation and pipeline monitoring

• Smart city infrastructure exposed to direct sun and thermal cycling

• Wireless sensor networks (WSN) in enclosed or unventilated housings

• Asset tracking and geolocation devices in hot climates

• Energy‑harvesting systems (solar, vibration, RF, thermal)

• Security and intrusion detection systems

• Remote monitoring and SCADA subsystems

These applications benefit from the TLI‑1550HT’s ability to deliver years of rechargeable, maintenance‑free performance under elevated temperatures.

Why Engineers Choose the TLI‑1550HT

• Rechargeable 4.0V industrial Li‑ion chemistry

• High‑temperature capability beyond standard rechargeable cells

• High cycle life for long‑term IoT deployments

• Fast recharge acceptance for energy harvesting

• High pulse capability for wireless communication bursts

• Extreme environmental resilience (thermal, mechanical, and electrical)

• Proven reliability in industrial and mission‑critical systems

The TLI‑1550HT is selected when designers need a rechargeable, high‑temperature lithium cell capable of powering autonomous IoT devices for a decade or more.
