The basis is in ” Advanced Materials ” report, nitrogen changes titanium (Titanium Nitride) with get together Bi (Polypyrene) for good replace data, former for conductivity tall data of as strong as corrosion resistance synthetic pottery and porcelain, by common titanium and azotic element composition, and make easily; Latter is a hydrocarbon, store the capacity can compete with black lead photograph, but as batteries anode material.

 

Because aluminous batteries electrolyte is extremely caustic strong, can corrode stainless steel and gold even, because this scientist is being searched,replace data or be to fight corrode material. And the breach that but say,nitrogen changes titanium is this research, this material holds back caustic electrolyte more effectively than stainless steel, also can produce with film at the same time, it is OK to come so Fu besmears the aggregate foil on batteries (Polymer Foils) , material of inorganic of ETHZ function sex teachs Maksym Kovalenko to think, research can promote the versatility of nitride further.

 

The scientist makes nitrogen successfully already change titanium aluminous battery in the lab (see a picture) . Kovalenko points out, nitrogen changes titanium to also can be used in metallic conductor, can presswork its even in plastic on, its apply potentially also not aluminous batteries of be confined to, also can use in sodium base batteries, magnesium radical batteries or batteries of high-pressured lithium ion.

 

Get together the molecular structure of Bi.

 

The 2nd kind of material gets together Bi is polymer element structure, when when its molecular catenary gathers without foreword, get together Bi can have conductivity. Kovalenko expresses, put between molecular catenary have a lot of spaces, can make electrolyte medium bigger ion can infiltration electrode material. The group thinks to get together Bi and nitrogen change titanium is to be able to flinch type stuff, be expected to be used at can flinching type batteries, but at present this material still is in lab phase.

 

These two material develop all hopeful promotes second birth the sources of energy store can apply. Illuminate that day intense as big as wind when, store can the technique can store effectively electric power, lest happen,lack report or be green can the corner of supply exceeds demand. Although be in store can in the technology, efficiency of lithium ion batteries is tall, also be current most extensive technology, but because content of lithium mine earth compares magnesian, natrium and aluminium even low, extraction also has difficult sex, lithium ion batteries does not suit big range to use.

 

The report points out, low cost of current and urgent need and but the stationary electric power that large-scale applying store can equipment, for this target, there already was wave of research and development of a new-style cell now, and these batteries are mostly by upper content tall and the spare parts composition that makes easily.
