Wow, that's about 40% more energy density than LiPo by weight and more than double by volume. :eek: Haven't heard anything else about them though, so...
 
(Li1.1V0.9O2) WTF!! Is it April 1st in Japan or have they got Hallowen misunderstood?
You don't have decimals only integers in a chemical formula! That's what an atom is INDIVISIBLE (short of nuclear reactons).
 
If you Google that daft formula limiting to the last month you get:
A Samsung Yokohama Research Institute and Samsung SDI on the use of lithium vanadium oxide (Li 1.1V0.9O2) of the new negative electrode material, delivered a speech entitled "the use of lithium metal oxide cathode of high-capacity battery proposal," the speech. 　　负极由Li1.1V0.9O2(LVO)和石墨混合而成。 By the negative Li1.1V0.9O2 (LVO) and a mixture of graphite. 两公司试制了直径18 mm×长65mm的圆柱形单元——“18650”。 Trial of the two companies had a diameter of 18 mm × length of 65mm cylindrical module - "18,650." 当单元的负极材料为30%的Li1.1V0.9O2(LVO)和70%的石墨混合而成，正极材料为LiCoO2时，终止电压为3.0V，电流容量为3080mAh，单位体积的能量密度达到了6 95Wh/L。 When the unit anode materials for 30% of the Li1.1V0.9O2 (LVO) and 70% of the mixture of graphite, the cathode material for LiCoO2, the termination voltage to 3.0V, current capacity of 3080mAh, the energy density per unit volume reached 6 95Wh / L. 　　该单元具有良好的充放电循环特性和低温特性，500次充放电后仍可实现80%以上的容量维持率，而且在-10℃的低温下可维持90%的放电容量。 The unit has a good charge-discharge cycle characteristics and low temperature properties, 500 charge and discharge after the realization of more than 80% of the capacity to maintain the rate, but also in the low temperature of -10 ℃ to maintain the 90% of the discharge capacity.

Vanadium? Here's the way to use it:

Aleees Reveals Details of Its LiFePO4 Cathode Material

Kouji Kariatsumari, Nikkei Electronics

Advanced Lithium Electrochemistry (Aleees) Co Ltd of Taiwan disclosed the technological features of and sales strategies for its lithium iron phosphate (LiFePO4), which was developed for use as a positive electrode material for Li-ion secondary batteries.

The LiFePO4 includes a small amount of metallic oxide, but it is added by co-crystallization not by doping or coating.

For example, a positive-electrode material added with vanadium oxide (V2O3) has a current capacity per mass of 155mAh/g, which is higher than that of the LiFePO4 being sold by other companies, Aleees said. Furthermore, only 0.2 weight percent of V2O3 can increase the electric conductivity of the material, enabling to keep the amount of carbon as low as 2 or 3 weight percent.

According to the company, the conductance of the Li ion is 1.9 x 10-2.

Aleees sells the material not only as powder but also as cells. The cells are manufactured by a Korean battery manufacturer. However, to provide the material as cells, the variation of internal resistance has to be reduced. Therefore, for the future, Aleees plans to contract with one of Japanese battery manufacturers that can produce high-quality cells, Aleees said.

Japanese battery manufacturers tend to avoid employing LiFePO4 because many related patents and exclusive licenses are allegedly owned by the University of Texas, Hydro-Quebec and Phostech Lithium Inc, which was established by Hydro-Quebec and is currently a wholly-owned subsidiary of Sud-Chemie AG.

Meanwhile, Aleees said it will take all the responsibilities if any lawsuit is filed against its positive-electrode material. The company also said that the price of the material could be about half that of other companies' materials because a wet process can be used.

Sure you can, it's done all the time when you have a mixture of ions in a formula like this one, which denotes a variable composition (i.e., not a "pure" chemical). Otherwise, you would have to distinguish between LiVO2 and Li11V9O20 and Li6V8O and Li41V55O7, etc., all of which would be close in composition and perhaps only one would give you the characteristics you need. Remember, that formula can be thought of as written in moles, not just atoms.
