  METHOD FOR RECOVERY OF THE CONSTITUENT COMPONENTS OF LATERITES

  摘要：

  用硫酸消化赤土矿石，除硅外，所有成分都会溶解。所得的硫酸盐——硫酸铝、硫酸铁、硫酸钛和硫酸镁——在大约90℃的溶液中保持稳定。热过滤可分离硅。溶液经过金属铁流动，将硫酸铁还原为亚铁硫酸盐。控制氨的加入促进水解并使水合钛酸钛从硫酸钛酸盐中沉淀，然后通过过滤除去。继续加入氨形成亚铁铵硫酸盐和铵铝硫酸盐溶液。明礬通过结晶优先分离。将氨加入铵明礬溶液中，沉淀出氢氧化铝，使铵硫酸盐保持在溶液中。剩余富含铁的液体中还含有硫酸镁。加入草酸会生成不溶性的草酸亚铁，经热分解后产生亚铁氧化物和一氧化碳，用于将亚铁氧化物还原为金属铁。进一步加入草酸会沉淀出草酸镁，然后经热分解产生氧化镁。

• Secondary lithium battery using a new layered anode material

  公开号：US05514490A1

  An improved lithium secondary battery using a novel layered titanium phosphate having the formula of TiO(OH)(H.sub.2 PO.sub.4), or LTP, as anode material, and LiCoO.sub.2, LiNiO.sub.2, or other appropriate material, as cathode. A stable operating voltage of 3-volt can be obtained from the resultant lithium secondary battery. The layered titanium phosphate is prepared by first reacting a tetramethylammonium hydroxide (N(CH.sub.3).sub.4 OH) solution containing orthophosphoric acid with titanium dioxide in a low temperature hydrothermal reaction to form a tetramethylammonium form of layered titanium phosphate, or NMe.sub.4 TP, which serves as the precursor of LTP. The precursor NMe.sub.4 TP is then placed in a concentrated hydrochloric acid at room temperature to obtain a high purity LTP via a cation exchange reaction. Each of the Li.sub.x LTP chemical unit, which is formed after the intercalation of LTP with lithium ions, can contain two lithium ions, thus excellent lithium intercalation characteristic can be achieved as a result. Furthermore, no lithium dendrites are formed during the recharging operation which tend to puncture the partition membranae separating the anode and the cathode; therefore, the secondary lithium battery allows a safe recharging operation to be maintained.

  一种改进的锂二次电池，使用一种新型层状钛磷酸盐（LTP），其化学式为TiO（OH）（H.sub.2 PO.sub.4）作为阳极材料，LiCoO.sub.2，LiNiO.sub.2或其他适当的材料作为阴极。由此产生的锂二次电池可以获得稳定的3伏特工作电压。层状钛磷酸盐是通过首先将含有正磷酸的四甲基氢氧化铵（N（CH.sub.3）.sub.4 OH）溶液与二氧化钛在低温水热反应中反应形成四甲基铵型层状钛磷酸盐或NMe.sub.4 TP，其作为LTP的前体。然后将前体NMe.sub.4 TP置于室温下的浓盐酸中，通过阳离子交换反应获得高纯度的LTP。每个Li.sub.x LTP化学单元，在LTP与锂离子插层后形成，可以含有两个锂离子，因此可以实现优异的锂插层特性。此外，在充电操作期间不会形成锂树枝，这些树枝倾向于刺穿隔膜将阳极和阴极分开；因此，二次锂电池可以保持安全的充电操作。

  A novel method for forming a dispersable, fine titanium pyrophosphate powder by reacting titanium dioxide and a molar excess of phosphoric acid. The excess phosphoric acid, at a phosphorus pentoxide to titanium dioxide mole ratio greater than one, significantly improves the yield of the reaction product as a fine powder.
