助听器锌空气电池的储存方法

原则上，锌空电池在存储过程中均会损耗能量。虽然有些电池的存储时间比其他电池要长。电池本身内在固有的电化学系统逐步损耗电池的能量，这个过程称为自放电现象，该过程与电解液中正极的材料属性有关，与它的热动力的不稳定性有关。自放电现象在可充电电池中的比率较在不可充电电池中要高。

In principle, zinc-air batteries will lose energy during storage. Although some batteries have a longer storage time than others. The inherent electrochemical system of the battery gradually loses the energy of the battery. This process is called self-discharge phenomenon, which is related to the material properties of the anode in the electrolyte and its thermodynamic instability. The rate of self-discharge phenomenon in rechargeable batteries is higher than that in non-rechargeable batteries.

可充电电池在室温中的自放电一般是(15%～25%)/每月，太阳能电池的每月自放电率比较低，约10%。该现象在不可充电电池中极低，室温中每年低于2%，但是这个值会受到许多因素的影响。

The self-discharge of rechargeable batteries at room temperature is generally (15% ~ 25%)/month, and the monthly self-discharge rate of solar cells is relatively low, about 10%. This phenomenon is extremely low in non-rechargeable batteries, below 2% per year at room temperature, but this value will be influenced by many factors.

在所有环境因素中，温度是最大的影响因素。这与发生在电极/电解质界面的温度依赖的电化学反应有关，那里可以认为是电池的心脏。温度下降，电极的反应率也随之下降，电流减小。使用时，逐步恢复至室温需要耗费大量的能量。温度上升，电极的反应率也随之上升，电流增大，消耗能量。冰箱的一般温度为0～10℃，是放电池的好地方。

Among all the environmental factors, temperature is the biggest one. This is related to the temperature-dependent electrochemical reaction at the electrode/electrolyte interface, which can be considered as the heart of the battery. When the temperature drops, the reaction rate of the electrode also drops and the current decreases. When in use, it takes a lot of energy to gradually return to room temperature. When the temperature rises, the reaction rate of the electrode also rises, the current increases, and energy is consumed. The general temperature of refrigerator is 0 ~ 10℃, which is a good place to put batteries.

其次影响因素为湿度。锌空电池的特点是直接与周围大气相连，如果相对湿度太低，电池中的电解质会慢慢变干;相对湿度太高，系统会存储水分，这两者都与锌空电池的性能相背。如果把电池存储在冰箱里，不要忘了，冰箱同时也提供了一个低湿度的环境，这就像放在冰箱中没有加盖的食物一样，食物会逐渐失水，慢慢变干。所以最好先把电池放入抗蒸发的包装里。

The second influencing factor is humidity. Zinc-air battery is characterized by being directly connected with the surrounding atmosphere. If the relative humidity is too low, the electrolyte in the battery will slowly dry out. If the relative humidity is too high, the system will store water, both of which are contrary to the performance of zinc-air battery. If the battery is stored in the refrigerator, don’t forget that the refrigerator also provides a low-humidity environment, which is just like the uncovered food in the refrigerator, the food will gradually lose water and dry out. So it’s best to put the battery in an evaporation-resistant package first.
