Description
本発明は、充放電可能な非水電解質二次電池の技術分野に属し、特に、非水電解質二次電池のエネルギー密度などの特性を著しく向上させる正極活物質の改良に関する。 The present invention belongs to the technical field of chargeable / dischargeable nonaqueous electrolyte secondary batteries, and particularly relates to an improvement in a positive electrode active material that significantly improves characteristics such as energy density of the nonaqueous electrolyte secondary battery.
次世代リチウム電池用正極活物質として各種の正極材料が報告され、その中でもＬｉＦｅＰＯ４が電気自動車電池用正極として最有力視されているが、その理論エネルギー密度は１７０ｍＡｈ／ｇで頭打ち状態であった。 Various positive electrode materials have been reported as positive electrode active materials for next-generation lithium batteries. Among them, LiFePO 4 is regarded as the most promising positive electrode for electric vehicle batteries, but its theoretical energy density was at 170 mAh / g and reached its peak. .
本発明者らは、先に非電解質二次電池の正極活物質としてフッ化金属を用いることを案出した〔特開平９−２２６９８号公報（特許文献１）；特開平９−５５２０１号公報（特許文献２）〕。このフッ化金属は、ＬｉＦｅＰＯ４のようなオリビン系正極よりも理論エネルギー密度（可逆容量）が高く、例えば、ＦｅＦ３／Ｌｉ電池は約２４０ｍＡｈ／ｇもの理論エネルギー密度を有するとされている〔H. Arai, et al., J.Power Sources, 68, 716 (1997)（非特許文献１）〕。しかしながら、フッ化物はイオン性化合物なので、電解液に含まれる極性溶媒に溶解し易いと考えられ実用に供されるには到らなかった。
本発明の目的は、フッ化金属の特長を活かした新規な非電解質二次電池用正極活物質を提供することにある。 An object of the present invention is to provide a novel positive electrode active material for non-electrolyte secondary batteries that takes advantage of the features of metal fluoride.
本発明者らは、フッ化金属を炭素質材料と充分に混練して正極活物質とすることにより、フッ化金属の本質的に有する理論エネルギー密度の維持された二次電池が得られることを見出し本発明を導き出した。 The inventors have found that a secondary battery in which the theoretical energy density inherently possessed by a metal fluoride can be maintained by sufficiently kneading the metal fluoride with a carbonaceous material to form a positive electrode active material. The present invention was derived.
かくして、本発明は、炭素でコートされた一般式ＭＦ３で表されるフッ化金属（Ｍは金属元素を示す）から成ることを特徴とする非水電解質二次電池用正極活物質を提供するものである。 Thus, the present invention provides a positive electrode active material for a non-aqueous electrolyte secondary battery, characterized by comprising a metal fluoride represented by the general formula MF 3 coated with carbon (M represents a metal element). Is.
本発明の非水電解質二次電池用正極活物質を構成する炭素コートされたフッ化金属ＭＦ３において、Ｍで示される金属元素としては、３価の金属であればいずれも適用可能である。適用される金属の例として、Ｆｅ（鉄）、Ｖ（バナジウム）、Ｔｉ（チタン）、Ｃｏ（コバルト）、Ｍｎ（マンガン）等が挙げられ、それぞれ、コートされたＦｅＦ３、ＶＦ３、ＴｉＦ３、ＣｏＦ３、ＭｎＦ３が正極活物質に用いられる。 In the carbon-coated metal fluoride MF 3 constituting the positive electrode active material for a non-aqueous electrolyte secondary battery of the present invention, any metal element represented by M can be applied as long as it is a trivalent metal. Examples of the metals to be applied include Fe (iron), V (vanadium), Ti (titanium), Co (cobalt), Mn (manganese), etc., and coated FeF 3 , VF 3 , and TiF 3 , respectively. , CoF 3 , and MnF 3 are used as the positive electrode active material.
非水電解質二次電池において如上の正極活物質とともに用いられる負極活物質としては、アルカリ金属またはアルカリ金属化合物が用いられるが、一般的には、リチウム（Ｌｉ）またはナトリウム（Ｎａ）である。本発明の炭素コートされたフッ化金属ＭＦ３を正極活物質とする系は、Ｌｉに対して容量の大きい可逆な充放電特性を示すのみならず、Ｎａに対しても同様に可逆な充放電特性を示す。 As the negative electrode active material used together with the positive electrode active material in the nonaqueous electrolyte secondary battery, an alkali metal or an alkali metal compound is used, and is generally lithium (Li) or sodium (Na). The system using the carbon-coated metal fluoride MF 3 of the present invention as the positive electrode active material not only exhibits reversible charge / discharge characteristics with a large capacity with respect to Li but also reversibly with respect to Na. Show properties.
例えば、Ｌｉ電池において炭素コートされたＦｅＦ３を正極活物質として用いると２００ｍＡｈ／ｇ以上の可逆容量（エネルギー密度）が実現されており、また、Ｌｉだけでなく安価なＮａ電池用正極としてもエネルギー密度の大きい可逆充放電反応が得られる（後述の実施例参照）。 For example, when FeF 3 coated with carbon in a Li battery is used as a positive electrode active material, a reversible capacity (energy density) of 200 mAh / g or more is realized, and energy can be used not only as Li but also as an inexpensive positive electrode for a Na battery. A reversible charge / discharge reaction having a high density is obtained (see Examples described later).
本発明が適用される特に好ましい例は、フッ化金属ＭＦ３としてＶＦ３を用いる場合であり、炭素コートされたＶＦ３を正極活物質とするリチウム電池では、充電特性と放電特性の差が殆どなく、きわめて効率的で且つ２００ｍＡｈ／ｇを超える高エネルギー密度の二次電池が実現される（後述の実施例参照）。 A particularly preferable example to which the present invention is applied is a case where VF 3 is used as the metal fluoride MF 3 , and in a lithium battery using a carbon-coated VF 3 as a positive electrode active material, there is almost no difference between the charge characteristics and the discharge characteristics. In other words, a secondary battery that is extremely efficient and has a high energy density exceeding 200 mAh / g is realized (see the examples described later).
その他、例えば、炭素コートされたＴｉＦ３、ＣｏＦ３、ＭｎＦ３などを正極活物質として用いることにより可逆な充放電特性を示しエネルギー密度の良好なＬｉ電池またはＮａ電池が得られる。 In addition, for example, by using carbon-coated TiF 3 , CoF 3 , MnF 3, or the like as a positive electrode active material, a Li battery or a Na battery having reversible charge / discharge characteristics and good energy density can be obtained.
本発明に従う炭素コートされたフッ化金属ＭＦ３は、原料となるフッ化金属試薬（添川理化学株式会社製）と炭素質材料とを不活性ガスの雰囲気下に機械的混合手段により４時間以上、乾式で混合することにより製造される。 The carbon-coated metal fluoride MF 3 according to the present invention comprises a metal fluoride reagent (manufactured by Soekawa Richemical Co., Ltd.) as a raw material and a carbonaceous material in an inert gas atmosphere by mechanical mixing means for 4 hours or more, Manufactured by dry mixing.
機械的混合手段として好ましく、一般的に用いられるのは、ボールミル、特に遊星型ボールミル（planetary ball milling）である。遊星型ボールミルは、自転・公転運動による粉砕エネルギーにより原料フッ化金属ＭＦ３と炭素質材料とを充分に粉砕・混合することができる点から特に好ましい。
混合時間は、４時間以上であり、一般的には２０〜３０時間であるが、正極活物質と負極活物質の組合せによっては、短い混合時間（例えば、４時間）が好適な場合もある。混合は、アルゴンガスのような不活性ガス雰囲気下に乾式で行う。
A preferred and generally used mechanical mixing means is a ball mill, in particular a planetary ball milling. Planetary ball mill is particularly preferable because it is possible to sufficiently pulverized and mixed with the raw material metal fluoride MF 3 and the carbonaceous material by pulverization energy due to the rotation-revolution.
The mixing time is 4 hours or longer, and generally 20 to 30 hours. However, depending on the combination of the positive electrode active material and the negative electrode active material, a short mixing time (for example, 4 hours) may be suitable. Mixing is performed dry in an inert gas atmosphere such as argon gas.
上記の工程において、フッ化金属ＭＦ３とともに混合される炭素質材料としては、導電性のある炭素系物質であればいずれも適用可能であり、例えば、アセチレンブラック、カーボンブラック、活性炭などを用いることができる。フッ化金属ＭＦ３：炭素質材料の比は、一般に、重量基準で５０：５０から９０：１０であり、例えば、７０：２５である。 In the above process, as the carbonaceous material mixed with the metal fluoride MF 3 , any conductive carbon-based material can be applied. For example, acetylene black, carbon black, activated carbon or the like is used. Can do. The ratio of metal fluoride MF 3 : carbonaceous material is generally 50:50 to 90:10 on a weight basis, for example 70:25.
以上のような操作に従い、フッ化金属ＭＦ３と炭素質材料とを充分に混和することにより、該フッ化金属の表面を炭素が均一にコートしていることは、ＳＥＭ（走査型電子顕微鏡）やＥＤＳ（エネルギー分散型Ｘ線分光）を用いる観察により確認されている。 According to the above operation, the surface of the metal fluoride is uniformly coated by thoroughly mixing the metal fluoride MF 3 and the carbonaceous material. SEM (scanning electron microscope) And observation using EDS (energy dispersive X-ray spectroscopy).
かくして、本発明は、フッ化金属ＭＦ３をベースとし、その微粒子の表面に炭素をコートすることによる導電性付与と電解質液への溶出抑制の双方の効果によってきわめて可逆容量（エネルギー密度）の高い非電解質二次電池を実現したものである。
以下、本発明の特徴を更に具体的に示すために炭素コートされた各種のフッ化金属ＭＦ３を正極活物質とするリチウム電池（Ｌｉセル）およびナトリウム電池（Ｎａセル）について行った充放電測定の実施例を記す。
Thus, the present invention is based on the metal fluoride MF 3 and has an extremely high reversible capacity (energy density) due to the effects of both providing conductivity and suppressing elution into the electrolyte solution by coating the fine particles with carbon. A non-electrolytic secondary battery is realized.
