 (May 2004) Saga University’s Institute of Ocean Energy extracts small amounts of lithium from seawater.  Although other laboratories have worked with this process, they have not pursued commercialization because of  low concentrations (about 0.1 to 0.3 mg/1.0 liter).  However,   at Saga University, the researchers   hope to commercialize the process.  Using a device containing specially processed manganese-dioxide crystals to absorb the lithium in the seawater, the researchers  have extracted about 30 grams of lithium chloride from 140,000 liters of seawater in a month.  The extracted lithium chloride has about 90 percent purity.

(Sept. 2003) T/J Technologies is awarded a National Science Foundation contract for  a battery program, “Synthesis of High Capacity Sn/MOx Nano Composite Anode Materials for Lithium Rechargeable Batteries”  The program is focused on developing and demonstrating materials that decrease the costs of Lithium-ion batteries to well be low the current $0.65/WH, and on increasing lithium battery safety for vehicle and stationary applications.

(December,01) Altair Nanotechnologies, Inc. has independent tests confirmed on their proprietary Li4Ti5O12 nanomaterials. Dr. K.M. Abraham tested the nanomaterials and found achievements in Lithium-ion charging and discharging rates to be 10 to 100 times higher when compared to materials commercially available today. The Li4Ti5O12-based lithium batteries have the ability to undergo charge/discharge cycles with little fade in capacity for thousands of cycles. Lithium Titanate Spinel is a specific crystalline phase of lithium titanate with a formula of Li4Ti5O12, which in Altair’s process is nearly 100 % pure.

(May, 02) Altair Nanotechnologies Inc.’s nano-sized lithium titanate spinel is being evaluated by global battery developers. “We look forward to the near-future development of prototype batteries utilizing our lithium titanate spinel,” commented Altair’s president Dr. William P. Long. “Through material testing thus far, it has been determined that non-sized lithium titanate spinel exhibits charge and discharge rates that are 10 to 100 times higher than with traditional materials commercially available today.”
