LiB合金在热电池中的应用特性研究OA北大核心CSTPCD

The characteristics of the LiB alloy with different lithium content and thickness and the short circuit at low temperature of LiB alloy as thermal battery anode were investigated.The results show that the thermal stability of LiB alloy decreases as the increase of the lithium content or thick-ness.Increasing the lithium content of LiB alloy within a certain range can not only greatly increase the pulse voltage,but also significantly increase the discharge capacity and extend the working time.Under certain operating condition,increasing the anode thickness can effectively resist the self-loss at high temperature of LiB alloy and greatly extend the working time at high temperature.At the activa-tion moment,the overflow of the free Li in LiB alloy is the basic reason for the short circuit at low temperature of thermal battery.
