Lithium thermal battery 70 from the late 20th century, has been developed for more than 20 years, during which tackled many technical difficulties, has become mature. Since the thermal battery with outstanding quality performance, and soon formed a variety of products, get in the successful application of modern weapons, has become the dominant thermal battery products, promote the improvement of performance of modern weapons. The rapid development of modern weapons has made the update on the thermal battery, higher demand, so lithium thermal batteries must continue to develop to meet these requirements.

Hot on the lithium battery anode materials, lithium or lithium alloy should be a good hot battery anode material, in the near future there can be no better alternative to their material. But as a thermal battery anode materials for lithium alloy, its varieties and production technology to improve its performance is still great potential to be tapped. Currently LiAl, LiSi alloy is widely used thermal battery anode material, the technology has been very mature. Thinkpad x200 tablet battery With lithium content up to about 70% (mass percentage) of LiB alloy’s excellent performance has been familiar, but its not easy to keep manufacturing technology, especially in high-volume manufacturing, due to the existence in the alloy formation process Zhong intense the exothermic reaction of two Once out of control exothermic reaction, the reaction temperature increased sharply, will LiB alloy porous structure is damaged, free from the porous structure of lithium adsorption capacity decreased significantly, making it as a serious deterioration in the performance of anode materials. Alloy is still currently overseas at the laboratory stage, a small amount of preparation technology (per 400g) success, and in some experimental products applied. China is also at the development phase, but product performance was unstable. Therefore, how to mass-scale production of stable performance of the LiB alloy, and can be widely used in thermal batteries, so performance is greatly improved in the future lithium thermal batteries is an important direction of development.

Lithium thermal batteries in the past by LiCl-KCl electrolyte eutectic-based. Although it is cheap, easy preparation, Toshiba Satellite L300 battery technical maturity and features, but after careful study that it also has some disadvantages, such as: low conductivity; discharge components susceptible to changes resulting in higher melting point; electrode material greater solubility in the electrolyte causing the battery self-discharge increases so hot. Therefore, thermal battery according to different performance requirements, select the appropriate electrolyte is lithium thermal batteries in the future an important direction of development.

Currently used in lithium battery cathode material heat mainly FeS2. As low discharge capacity of the material, and lithium alloy anode very match, but also thermal decomposition, long-term increase hinder the overall performance of thermal batteries, become a focus of attention. Looking for discharge capacity of lithium alloy anode and match possessed high thermal stability of the cathode material has been the goal.
