EnFilm : 固体薄膜バッテリ

STのEnFilm™ 薄膜バッテリは、ライフ・サイクルが長く高速充電が可能な新しい概念の超薄型(200 µm)再充電可能固体バッテリです。

EnFilmデバイスは、25.4 x 25.4 mmのフットプリント上のLiCoO2カソード、LiPONセラミック電解質、およびリチウム・アノードを特徴としています。 

Evaluation kit and board now available

The design of solid state thin film battery EnFilm™ EFL700A39 powered applications can now be evaluated and supported thanks to ST’s newly available kit and board:

  • The EFL700PMB – power management board – includes all the necessary power management circuitry around the EFL700A39 for charging and voltage regulation, deep discharge protection and a super-capacitor to sustain a high pulsed discharge current. It can be directly connected to the application for rapid performance evaluation. 
  • The EFL700EVALKIT – evaluation kit – includes the EFL700PMB as well as an LB with analog ammeter and digital voltmeter that enable discovery of the performance of the EFL700A39 by monitoring the voltage and the dynamic charge / discharge current in real use-case conditions. It also includes a pulsed load emulator to simulate applications that wake from sleep mode periodically.

The first interactive payment ISO card ‘CAPI’ embeds EnFilm™

CAPI is the first interactive, rechargeable, payment card designed by a consortium including Gemalto, Worldline , Linxens , IPDIA, Ensicaen, CEA, Elitt , GIE CB and ST. It offers many innovative features and functions – through the use of a tiny embedded alphanumeric bistable display – such as One-Time Password (OTP), digital CVX2 , message, promotion, and account balance.
A stack of two of ST’s EnFilm thin-film batteries – the EFL700A39 – powers CAPI for up to 36 operations, before requiring a recharge within the payment terminal or ATM. The circuit and EFL700A39 are assembled on a flex before lamination in the card. The form factor is compliant with the ISO standard with a typical thickness below 900 µm.
