Ceramic-packaged all-solid-state battery
Ceramic-packaged all-solid-state battery

Heat resistance and high sealing property∗1 have been achieved by adopting a ceramic package as the exterior package. Mounting on a circuit board by reflow soldering method∗2 is possible.

power supply module kit for evaluation

Maxell’s all-solid-state batteries can be easily evaluated with a low-current-consumption*3 power supply module kit for evaluation using a boosting DC-DC converter IC which installs Nano Energy™ ultra-low-current-consumption∗3 technology of ROHM Co., Ltd.

  • In a helium leak test, a level of 10-11(Pa・m³/sec) was achieved. The sealability of a general coin-type battery is 10-8(Pa・m³/sec) level. Refer to JIS Z 2330.
  • The heat resistance at the +245 deg. C level is confirmed in the reflow process. For detailed conditions, please contact Maxell.
  • Low current consumption: Static current (at non-switching) 180 nA (typ.) of the boosting DC-DC converter IC (BD8B133NVX). For details, refer to the product page of the Nano Energy™ ultra-low-current-consumption technology. https://www.rohm.com/support/nano#anc-02

Power supply module kit for evaluation of ceramic-packaged all-solid-state battery

Maxell and ROHM Co. Ltd.(ROHM) jointly developed the low-current-consunption power supply module kit for evaluation, using boosting DC-DC convertre IC, which installs the Nano-Energy™ ultra-low-current-consumption technorogy of ROHM The aim of this kit is that many customers can adopt the ceramic-packaged all-solid-state battery at an early stage by simplifying the evaluation.
