乐发9　　A Japanese research team developed a lithium ion battery based on solid medium, can improve the adaptability of the battery, have wider environmental temperature.  

The team developed a can produce electric current of the dielectric, like a electrolyte with existing lithium-ion batteries, its shape is solid, with the research team created a solid-state lithium batteries, after many experiments, the electrical conductivity can achieve the level of the existing liquid lithium ion battery. 

　　Lithium battery is mainly used in consumer electronics, the application of the larger market is electric cars. Both digital batteries, power batteries, are now liquid lithium ion battery, polymer battery is also a kind of lithium battery, the electrolyte is between solid and solid structure, this is because under the existing technology, efficient, high density of chemical battery can only be achieved by liquid dielectric, the existing solid dielectric actual conductivity is very low, can only be reached around one over ten of the liquid electrolyte, sensitive to temperature changes, work limit temperature is 50 ℃ to 80 ℃. 

　　Team used lithium superionic Li10GeP2S12 new material can effectively solve the above problems, the material is still in lithium ion conductor, but give them a layer crystal structure, natural crystal lattice become ions through holes, the outer structure generated allow ions to sports channel. After tests found that the conductivity achieves the level of the existing liquid lithium battery, and the new battery can in - 100 ℃ to 100 ℃ temperature range between work, makes the battery application performance greatly improved.
