England Gelasige university (UOG) the leader's group is electrode material with plant starch and canal of carbolic accept rice, with 3D the technology that print made battery of a kind of new-style lithium. This will be offerred for mobile equipment more the power supply with environmental protection, larger size. Relevant research achievement is published in " power source magazine " in.

The microcosmic configuration of poriferous structure (left) fill batteries of ion of lithium of discharge function 　 to have circularly with electrode light qualitative, compact as better as circular function wait for an advantage, suit to use as very much the power source of watch of notebook computer, mobile telephone, intelligence and electric car. Lithium ion batteries includes the positive electrode that oxide of lithium cobalt, manganese or lithium of phosphoric acid iron make, and the negative pole that metallic lithium forms. Charging in the process, lithium ion passes electrolyte, flow to negative pole from positive electrode. In discharge process, ion turns over directional flow, through electrochemistry reaction produces energy, provide power for equipment. Electrode ply is one of main physics factors that affect lithium ion to batteries stores and release energy. Thick electrode meets those who restrict lithium ion to go up in electrode diffuse not only the effect, restrict lithium ion batteries then than can, the strain that still can reduce batteries is able to bear or endure suffer a gender, make its easier because of craze invalidation. The batteries that UOG designs aims to pass introduce small hole of accept rice class, better balance is built to concern between electrode dimension and electrode watch area. With external dimension equal solid electrode photograph is compared, the watch area of small hole electrode gets addition significantly. For this, researcher use 3D is printed (add material to make namely) technology, undertook be controllinged accurately to the dimension of small hole on electrode and position. The raw material that 3D prints basically is get together lactic acid, lithium - iron phosphate and canal of carbolic accept rice. Among them, get together lactic acid is be machined by corn starch, sugar cane starch, beet starch and become but biology degradation material, it increased cell effectively can reclaim quality. Researcher checked different ply (100, 200 with 300 micron) , different material is combined (3%~10% of content of canal of carbolic accept rice) different small hole is led (10%~70% ) the function of circular electrode. The result makes clear, the electrode performance that 300 micron ply, 70% small hole lead is good, are its compared can you be 151 MAh? G-1, the 2~3 that is the capacity of batteries of traditional lithium ion that uses electrode of coequal ply solid about times. This kind optimized means to also solve the problem that electrode ply brings. relatively at the electrode with 100 thick micron, of 300 micron thick electrode store capacitance rose 158% . Project controller Dr. Shanmugam Kumar says: Batteries of “ lithium ion had held significant position in daily life. As electrification and the development that can change development continuously, its importance still will continue to promote. However, of oneself of lithium ion batteries but durative problem nots allow to ignore. In this research, we use 3D to printed craft to undertake be controllinged accurately to the small hole rate of electrode, the flaw of batteries of existing lithium ion was remedied on certain level. The potential application sex that we hope to continue to explore material of electrode of this kind of small structure, develop what function reclaims more primely, more easily to be able to circulate then lithium battery. ”
