Portable lithium battery technology to tame successfully developed the bomb safe
With the current rapid spread of digital devices, rechargeable lithium-ion batteries have been widely applied to various electronic products, although the lithium battery has a small size, rechargeable use features. But in recent years the weakness of its instability is gradually exposed. Mobile phone battery exploded by now should be common, and even some international brands of computers have also heard the battery hidden dangers.
To solve this problem, Korea Atomic Energy Research Institute researchers developed in the recent success of the new lithium battery technology, the study added a new battery isolation device, through the polyethylene, nano-aluminum and resin materials to ensure the battery temperature at 150 °C still security and stability, but also to protect the battery from the collision impact.
National network with independent intellectual property rights successfully developed large-capacity storage monomer sodium sulfur battery
National Grid and the Shanghai Institute of Ceramics, Chinese Academy of cooperation after many years, recently successfully developed with independent intellectual property rights when the security capacity of 650 single sodium sulfur storage battery, and has successfully completed the 2.2 kW sub-module of sodium sulfur battery the first charge and discharge, making China the world after Japan, the second largest capacity to master the core technology of sodium sulfur batteries single country. Large-scale application of large-capacity storage battery, the difference between peak and valley is conducive to resolving power, solar energy and wind power and other new network problems and improve the utilization of existing power facilities, reduce coal consumption and electricity line losses, and to some extent solve the power imbalance between supply and demand, improve power supply reliability and power quality for building a strong intelligence network to play an important role.
Sodium sulfur battery is a kind of metallic sodium anode, sulfur as the cathode, electrolyte membrane tubes for the secondary battery, under certain conditions, can be formed by chemical reaction of energy release and storage. Such batteries with large capacity, small size, high efficiency energy storage and conversion, long life, without geographical restrictions, etc., is the most economical and practical storage methods.
