Suppliers lithium iodine

Lithium-iodine (Li-Ij) batteries were specifically designed and developed for medical applications. These batteries consistently demonstrated the best performance and suitability, particularly for pacemakers, over a period exceeding 25 years. This particular battery is high in energy density but low in power level. Li-Ij is a low-conductivity solid-state electrolyte, which limits the current to a few microamperes. According to the manufactures, an operational life ranging from 7 to 12 years for this battery has been demonstrated in the field. The battery suppliers claim that these batteries could be used in other applications, such as watches and memory-retention devices. 

Since 1972, the Catalyst Researeh Corporation (USA) has been the supplier of the lithium-iodine batteries intended initially for eardiae paeemakers and other implantable deviees. They supply 70% of pacemaker batteries used in the world. They elaim that the capacity of this battery is four times that of the Mallory RM-I mereury-zine paeemaker battery and that the lithium-iodine battery operates more efficiently at body temperature than at room temperature. Since the lithium-iodine reaetion generates no gas, the cell can be hermetieally sealed. A feature of this type of battery is its extremely high reliability. At the time of writing, Catalyst Researeh had supplied 150000 batteries for use in eardiae paeemakers without a single failure or premature rundown. Catalyst Researeh Corporation lithium-iodine batteries are marketed in the UK by Mine Safety Appliances Ltd. 

Since 1972, Catalyst Research Corporation has been the supplier of lithium-iodine batteries for cardiac pacemakers and other medical implantable devices and, more recently, for other applications of these batteries. 

Table 4.6 summarizes the major lithium-carbonate producers and suppliers. Close examination indicates that SQM s lithium-rich brine operation is now the largest lithium-carbonate operation in the world. In addition to lithium carbonate, the Minsal facility has the capacity to produce annually 300,000 tonnes of potash, which it uses at its local fertilizer operation, 250,000 tonnes of potassium chloride, and 16,000 tonnes of boric acid and, to a lesser extent, iodine.
