Definitions
- the present invention relates to the synthesis of lithium transition metal oxides in general and lithiation of dual and multiple metal hydroxides in particular.
- Lithium-ion battery systems are gaining increased industrial , commercial and consumer acceptance because of their superior energy density and power density over other rechargeable battery technologies. As a result, they are increasingly being used in or contemplated for a wide variety of applications - portable electronic devices, toys, cameras, portable computers, cell phones, electric vehicles, etc. either as primary or secondary energy sources.
- LiCo0 2 (lithium cobalt oxide) is currently used as the major active cathodic material in lithium-ion batteries.
- lithium cobalt oxide is made by a solid-state reaction between a lithium compound and a cobalt compound occurring at high temperatures
- the aforementioned process utilizes extraneous activators or catalysts that may contaminate the lithiated product .
- LiCo0 2 lithium metal oxides
- Ni/Mn or Ni/Mn/Co based mixed lithium oxides with layered structures are considered promising cathode materials for Li batteries with better performance including large scale automotive applications than the currently used LiCo0 2 .
- LiM0 2 and similar materials by combining M(0H) 2 (M being a selected metal or metal combination suitable for lithium-ion energy cells including cobalt, nickel, manganese, etc.), LiOH and water to form a slurry solution.
- An oxidant such as oxygen or an oxygen containing gas such as air, is introduced into the solution and the mixture is heated to about 30-150 °C.
- the resultant lithiated compound crystallizes in-situ.
- Figure 1 is an x-ray diffraction pattern of an embodiment of the invention.
- Figure 2 is a charge/discharge curve at c/10 rate in a cell.
- Figure 3 is an x-ray diffraction pattern of an alternative embodiment of the invention.
- LiCo0 2 is currently used as a cathodic material in lithium battery systems.
- the present low temperature process for making a lithiated oxide is relatively simple and more efficient when compared to current commercial techniques .
- M(OH) 2 is added to an aqueous solution with a high concentration of LiOH to form a slurry solution.
- An oxidant is introduced into the slurry with appropriate agitation at a temperature of about 30-150 °C, preferably about 80-120 °C, at essentially atmospheric pressure for about 2-24 hours or until the crystallized product has formed.
- the solid/liquid separation can be accomplished by filtrating or centrifuging the reacted slurry.
- the reaction is a combination of the oxidation of M(OH) 2 and insertion of Li ions into the layered structure. Therefore, reaction conditions with higher Li concentrations are more favorable for completing the reaction.
- the solubility of LiOH in water is about 5M at room temperature, but it is around 8M at 100°C.
- no contaminants will be introduced into the product because no activators or catalysis are required during the reaction and only LiOH, M(0H) 2 and oxygen (pure or as part of a simple oxidant) are used as the reactants.
- no waste is generated because the filtrate, mainly containing LiOH, is reusable. The cleansed filtrate may be recycled.
- the present process generates lithiated layered- oxide (space group: R-3m) with (003)F HM (Full Width Half Maximum) of about 0.3° and (IOI)FWHM of about 0.2° without the need for a subsequent heat treatment.
- space group: R-3m space group: R-3m
- (003)F HM Full Width Half Maximum
- IOI IOIFWHM
- a subsequent heat treatment step may be utilized.
- the time for the optional heat treatment step to raise crystallinity higher is significantly shorter by the order of 10-12 hours.
- the present process By preferably utilizing M(OH) 2 particles as a precursor as opposed to ball milled ingredients, the present process generates lithiated oxide powder product without breaking or aggregating the original particles. This results in better control of both powder size and morphology. Moreover, the entire prior art ball milling process or other mixing process is eliminated.
- LiCo0 2 was produced in the following manner: 100 grams of Co (OH) 2 were introduced into a 1000 mL vessel having a LiOH concentration in water of about 5-8M at atmospheric pressure. Oxygen gas was introduced into the vessel at a flow rate of about 100-150 mL/minute . The temperature of the solution was maintained between about 80-120 °C and agitated with an impeller at about 750 revolutions per minute for about 24 hours. Upon completion of the process, the solution was filtered and the crystallized solid powder LiCo0 2 with layered structure was collected. (003)FWHM of about 0.3° and (101) FWHM of about 0.2° from XRD spectra were measured for the sample without any heat treatment. Upon review of the data, the actual processing time may be reduced to about 5 hours.
- Figure 1 shows an XRD (x-ray defraction) of resulting crystallized LiCo0.
- XRD x-ray defraction
- Figure 2 shows the result of an electrochemical c/10 test at c/10 rate in a small cell on the lithiated sample without heat treatment (the sample was dried at about 100°C) .
- the discharge capacity is approximately 130 mAh/g.
- the present process may be used for crystallized multiple lithiated oxide compounds. For example, it appears that some mixed or multiple oxides may have better properties than LiCo0 2 in lithium-ion cells. By introducing a mixed hydroxide precursor into the lithium hydroxide solution at a relatively low temperature excellent results are achieved.
- Nio.55 Mn 0 . 45 (OH) 2 as a precursor was introduced into the above 4-8M LiOH solution and heated at about 80-120 °C for about 24 hours.
- 0 2 was introduced as the oxidant.
- the favorable results - layered LiNio.55Mn 0 . 5 0 2 - are shown in Figure 3 after lithiation in an aqueous slurry solution. Crystallinity was measured at (003) FWHM of about 0.24° and (101) FWHM of about 0.78°. An optional heat treatment at about 850°C for seven hours increased the crystallinity to (003) FWHM of about 0.10° and (101) FWHM of about 0.17°.
- Nio. 55 Mn 0 s (OH) 2 as a precursor was introduced into the above 4-8M LiOH solution and heated at about 80-120 °C for about 24 hours. Air was introduced as the oxidant at 350mL/minute . The layered product of LiNio. 55 Mn 0 . 5 0 2 was obtained.
- Crystallinity was measured at (003) FWHM of about 0.30° and (101) FWHM of about 0.89°.
