However, because ER batteries are\nnon-rechargeable, periodic battery replacement and the disposal of used\nbatteries present ongoing operational challenges.\n\nThe newly developed module integrates a wireless charging circuit, highly\nheat-resistant and highly reliable all-solid-state batteries, and a boost\ncircuit into a 1/2AA-size, while delivering the same 3.6 V output voltage as\nconventional ER batteries. When used in combination with the dedicated\ncharger(*2), it enables wireless charging(*1) capability to be added to\nexisting equipment without requiring complex circuit design.\n\nBy incorporating rechargeable all-solid-state batteries, the module helps\nreduce battery replacement work and minimize battery waste. In addition, its\nwireless charging(*1) capability eliminates the need for openings in device\nhousings for battery replacement or charging, making it suitable for equipment\nthat requires a high degree of sealing performance.\n\nOne potential application of this module is temperature loggers for food used\nin the sterilization process of retort foods require both heat resistance and\na high degree of sealing performance to prevent moisture ingress.\n\nCurrently, Maxell is conducting a joint feasibility study with House Foods\nCorporation\n(https://cts.businesswire.com/ct/CT?id=smartlink&url=https%3A%2F%2Fhousefoods-group.com%2Fen%2Fcompany%2Fgroup%2F&esheet=54593395&newsitemid=20260825352141&lan=en-US&anchor=House+Foods+Corporation&index=3&md5=0d8f765f6c870da8c0829f0b049074a1)\non a temperature logger for food process using this module.\n\n*1 Wireless charging: This function may not be available depending on the\nenclosure material used in the customer’s equipment.\n\n*2 Dedicated charger: A dedicated design tailored to the customer’s\nequipment is required.\n\nFor more details, please refer to the information here\n(https://cts.businesswire.com/ct/CT?id=smartlink&url=https%3A%2F%2Fssl4.eir-parts.net%2Fdoc%2F6810%2Fir_material4%2F284623%2F00.pdf&esheet=54593395&newsitemid=20260825352141&lan=en-US&anchor=here&index=4&md5=43c4a053acb7d53045f79774b62510d0)\n.\n\nTrademarks\n\nThe names, logos, and service marks mentioned herein are registered trademarks\nor trademarks　of Maxell or their respective companies.\n\n\n\nView source version on businesswire.com:\nhttps://www.businesswire.com/news/home/20260825352141/en/\n(https://www.businesswire.com/news/home/20260825352141/en/)\n\nCustomer Inquiries \n(https://cts.businesswire.com/ct/CT?id=smartlink&url=https%3A%2F%2Fbiz.maxell.com%2Fen%2Frechargeable_batteries%2Finquiry_form_input1.html&esheet=54593395&newsitemid=20260825352141&lan=en-US&anchor=Customer+Inquiries&index=5&md5=ef783bf505976140041bdd9f4521ba69)\n\nMarketing & Sales Div., Maxell, Ltd.\n\nmarketing_sales@maxell.co.jp (mailto:marketing_sales@maxell.co.jp)\n\nMedia Inquiries \n(https://cts.businesswire.com/ct/CT?id=smartlink&url=https%3A%2F%2Fmaxell.tayori.com%2Ff%2Ftayori-01e%2F&esheet=54593395&newsitemid=20260825352141&lan=en-US&anchor=Media+Inquiries&index=6&md5=5c6bed73de8672d8c5093536c26d9ea0)\n\nHitoshi Yamagata\n\nPR&IR Dept., Maxell, Ltd.\n\nhitoshi-yamagata@maxell.co.jp (mailto:hitoshi-yamagata@maxell.co.jp)\n\n\nCopyright Business Wire 2026","article_body_html":"","raw_payload":{"data":{"id":"nBw649Z55a","title":"Maxell Develops ER Battery-Sized All-Solid-State Battery Module Supporting Wireless Charging*1","author":"Business Wire","ticker":"6810","created":"2026-08-25T12:00:02.267Z","tickers":["6810"],"exchange":"TSE Tokyo","article_body":"Maxell Develops ER Battery-Sized All-Solid-State Battery Module Supporting\nWireless Charging(*1)\n\nContributing to Improved Maintenance Efficiency and Reduced Environmental\nImpact through Reduced Battery Replacement Frequency and Reduced Battery Waste\n\nMaxell, Ltd.\n(https://cts.businesswire.com/ct/CT?id=smartlink&url=https%3A%2F%2Fwww2.maxell.co.jp%2F&esheet=54593395&newsitemid=20260825352141&lan=en-US&anchor=Maxell%2C+Ltd.&index=1&md5=5ded482764e961ad6598bfcc09ff8b0c)\n(TOKYO: 6810) has developed an all-solid-state battery\n(https://cts.businesswire.com/ct/CT?id=smartlink&url=https%3A%2F%2Fbiz.maxell.com%2Fen%2Frechargeable_batteries%2Fallsolidstate.html&esheet=54593395&newsitemid=20260825352141&lan=en-US&anchor=all-solid-state+battery&index=2&md5=255d1e8aac4fa45dd489c0fe0672bb45)\nmodule compatible with a 1/2AA-size (diameter 14.5 mm, height 25.2 mm) lithium\nthionyl chloride battery (hereinafter ER battery), along with a dedicated\ncharger(*2).
