Energy Harvesting

TLI Series industrial grade rechargeable Li-ion cells are ideal for energy harvesting

Energy harvesting devices are typically utilized in remote wireless applications where average current is high enough to prematurely exhaust a primary (non-rechargeable) cell. These applications require the use of a rechargeable lithium-ion (Li-ion) battery working in tandem with the energy harvesting device to store the harvested energy. 

Standard rechargeable lithium-ion cells are typically well-suited for consumer applications, but have inherent drawbacks for industrial applications, including short operating life (maximum 5 years), low maximum cycle life (500 cycles), high annual self-discharge (up to 60% per year), an inability to deliver high pulses, and a limited temperature range (0°C to 60°C) with no possibility of charging at low and high temperatures.

By contrast, industrial grade TLI Series rechargeable Li-ion batteries deliver reliable, long-life performance in extreme environmental conditions, featuring longer operating life (20 years), up to 10 times more life cycles (5,000 full cycles), a wider operating temperature range (-40°C to 85°C, with storage up to 90°C), the ability to deliver high current pulses (up to 5A for AA cell), a low annual self-discharge rate (less than 5%), and the ability to be charged and discharged at extreme temperatures. A specially modified version is also available for medical applications requiring high temperature autoclave sterilization at up to 125°C.

Available in AA and AAA cylindrical cells and custom battery packs, TLI Series industrial grade Li-ion batteries provide a rugged, long-term power supply that be recharged using DC power or with energy harvesting devices.

TLI Series batteries can also be utilized in combination with bobbin-type LiSOCl2 batteries to deliver back-up power solutions for energy harvesting applications. For example, in situations where a solar PV panel experiences extended periods without sunshine (i.e. polar winter or 5 consecutive days of cloudiness) an ideal solution may be to support the TLI Series rechargeable battery with a bobbin-type LiSOCl2 battery to reduce the size and cost of the solar PV panel and the rechargeable Li-ion batteries.

Key Features:

  • Longer operating life (20 years)
  • Up to 10 times more life cycles (5,000 full cycles)
  • Wider operating temperature (-40°C to 85°C, with storage up to 90°C)
  • Ability to deliver high current pulses (up to 5A for AA cell)
  • Low annual self-discharge rate (less than 5%)
  • Charging possible at extreme temperatures (-40°C to 85°C)
  • Glass-to-metal seal (others use crimped seals that may leak)
