    应用特点:一、在锂电池中,纳米二氧化钛具有极好的高倍率性能和循环稳定性,快速充放电性能和较高的容量,脱嵌锂可逆性好等特点,在锂电池领域具有很好的应用前景。1)纳米二氧化钛能有效降低锂电池的容量衰减,增加锂电池稳定性,提高电化学性能。2)提高电池材料的首次放电比容量。3)降低了LiCoO2在充放电过程中的极化,使材料具有更高的放电电压及更平稳的放电效果。4)适量的纳米二氧化钛可以疏松状存在,降低了粒子间应力及循环过程中所造成的

    结构和体积的微小应变,增加电池的稳定性。

    、在化学能太阳能电池中,纳米二氧化钛晶体具有光电转换率高、能很大提高太阳电池的能量转换率、成本廉价、工艺简单及性能稳定的特点。其光电效率稳定在10%以上,制作成本仅为硅太阳电池的1/5~1/10.寿命能达到20年以上。三、在镍镉电池中,纳米二氧化钛具有良好的导电性、宽温度工作范围的特点。

    用量:建议添加量0.5-2%。

    包装 15公斤/纸桶内衬塑料薄膜袋。
