技術詳情
本成果是用于無線充電用高效導磁材料,用于與充電線圈復合,提供磁 力線閉合回路的通道,聚集感應線圈加電流后產生的磁力線,保證主要 的磁通都經過磁性導磁片而形成閉合的回路,從而提高充電效率。另外 的功能是抗金屬干擾,充電線圈在100_200kHz的頻率產生的磁通,會 在電池上產生渦流,形成反向磁通,抵消充電的磁通,降低效率,因此, 也起到抗金屬的作用。采用該導磁片的充電效率超過70%,相比同類產 品,相同厚度的情況下優勢突出。該產品的主要優點是柔性、高磁導率、 低損耗,充電效率高,超薄,后加工簡單,成本低廉,實用性強。對于 手機數碼產品,空間尺寸要求比較嚴格,本成果導磁片產品恰恰滿足了 超薄的需求,最小厚度達到50微米,是所有傳統軟磁材料無法比擬的, 對于越來越多的手機數碼、可穿戴電子設備,線充的接口影響著產品的 整體設計,因此,無線充電的發展趨勢越來越迫切,整個市場份額超過 1000億元。對于促進非接觸式充電技術的發展,提供了關鍵的軟磁材料 解決方案,同時,還會接連推出第二代和第三代軟磁材料備選方案。
技術優勢

目前,己成功應用于三星S6系列手機中,在S6、S6edge和note5、S6 edge+等手機中,非晶導磁片己經大批量成功使用,充電效率超過70%, 而且是國內唯一供應商。

適用對象

主要應用于手機、移動數碼、pad等電子產品的非接觸式充電的發射端和接收端。
