Long-life rechargeable Li-ion cells suit extreme environments

The expanded TLI series offers a family of long-life rechargeable Li-ion cells designed for use in harsh environments. The batteries are available in AA and AAA diameters, and custom battery packs. The cells can be recharged using dc-power or can be used in conjunction with photovoltaic solar systems or other energy harvesting devices for long-term power.

The batteries use technology found in the company’s patented hybrid layer capacitor (HLC), which stores the high current pulses required for two-way wireless communications, and delivers 25+ years of service life, an operating temperature from -40°C to 85°C, the ability to deliver up to 5-A current pulses for AA cells, a self-discharge rate of
