一文了解村田硬币型二氧化锰锂电池的特点及应用

由 judy 提交于

<p>村田的硬币型二氧化锰锂电池（CR电池）是正极使用二氧化锰，负极使用锂的小型一次电池。被广泛用于智能进入系统和TPMS（Tire Pressure Monitoring System）等汽车相关设备、IoT相关设备、存储备份电源等用途。</p>

<p><strong>特点</strong></p>

<ul>
<li>轻量、高电压、高能源密度：电池电压3V约干电池的2倍。至今为止需要2块电池情况，现在使用1块电池就可以了，能够节省空间实现轻量化。</li>
<li>优越的放电稳定性：即使是长时间放电，也能显示出稳定的电压特性，所以在提高使用设备的可靠性的同时节省了电池更换的维护。</li>
<li>广泛的工作温度范围：使用独特的有机电解液，使得在低温~高温领域都具有优越的特性。</li>
</ul>

<p>&nbsp; &nbsp; &nbsp; &nbsp;・－30℃ to ＋70℃（标准型） －40℃ to ＋125℃（耐热型）</p>

<ul>
<li>优越的耐漏液性：通过使用最新研发的电池构造和电解液，使得长时间具有优越的耐漏液性。</li>
<li>优越的保存特性：活性物质、电解液具有通过严选稳定性高的物质以及独特的封装技术，具有自放电少的特征。相对于公称容量常温常湿的环境下的自放电量年间不足1%。</li>
<li>UL元件认定合格产品：村田的硬币型二氧化锰锂电池电池是UL元件认证合格产品。（UL1642 File No. MH12566）</li>
<li>EU电池指令・RoHS指令</li>
<li>该电池不含有EU电池指令规定的3种物质（水银、镉、铅）3种物质，符合该标准。</li>
<li>该电池是RoHS指令对象外。</li>
</ul>
