STMicroelectronics has released an innovative new concept in energy storage, the EnFilm™ lithium thin-film battery.
This rechargeable solid-state battery design is extremely thin. It also recharges quickly with a
constant-voltage input, taking just 20 minutes to reach 80% of full capacity from a completely discharged state, from an input of 4.2V. Self-discharge is also low, losing just 3% of its charge over the course of a year.
Offering a long lifetime of more than 10 years, the first EnFilm battery, the EFL700A39, is rated for 4,000 cycles. Its long cycle life makes it ideal for industrial process monitoring.
The EFL700A39 is UL certified and complies with the following international standards:
- IEC 62133
- UN Manual of Tests and Criteria, Part III, subsection 38.3
- ISO7816/IEC 10373 (mechanical/flexibility smartcard standards)
The battery has a LiCoO2 cathode, LiPON ceramic electrolyte and a lithium anode.
|Operating voltage||3.0V to 4.2V|
