Energy harvesting devices require the use of a rechargeable lithium-ion (Li-ion) battery to store the harvested energy.
Standard consumer grade rechargeable lithium-ion cells have inherent drawbacks, 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.
• 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)
