High Temperature Lithium Polymer Batteries from China

高温电池

当前伴随科技的进步以及对高温电池的实际应用的需求， 很多领域需要用到高温电池， 尤其是可充的高温电池。

Together with technology’s imporvement and actual demanding of high temperature batteries, there are many field in great demand of low temperature rechargebale ones.

当前 中国行业内大多数的高温电池能够承受的温度最高为75摄氏度。

Currently, almost all of batteries of China battery line can stand high temperature rate at 75 degrees.

而某公司生产高温可充电池能承受的最高温度是80摄氏度， 且在不同的温度调价下能都放出的容量不尽相同， 如下表：

While one compay high temperature battery can stand at most 80 degrees, what’s more, the capacity is different at various tem range, such as:

Temperature range温度范围      Duration 时间    Typ. Capacity recovery恢复容量

-20oC - +80oC                  10 days          50%(expected)

-20oC - +60oC                  1month          75%(expected)

-20oC - +45oC                  3months         70%(expected)

-20oC - +25oC                  1year            80%(expected)

Do not storage at fully charged state (4.20V) for a long period of time。
