Description
本発明のリチウム二次電池の正極(以下、単に「正極」と称する。)は、導電性物質からなる正極集電体と、リチウム複合酸化物焼結体板からなる正極活物質層と、を備えている。前記正極活物質層と前記正極集電体とは、導電性接合層(導電性接着層)を介して接合されている。また、本発明のリチウム二次電池は、前記正極の他に、炭素質材料又はリチウム吸蔵物質を負極活物質として含む負極と、電解質と、を備えている。前記電解質は、前記正極と前記負極との間に介在するように設けられている。本発明の特徴は、前記正極活物質層が、厚さが30μm以上であり、平均気孔径が0.1〜5μmであり、空隙率が3%以上であり且つ15%未満であることにある。
厚さをt、
板面方向(厚さ方向と直交する方向)における最小寸法をw、
とした場合に、
w/tが3以上となるように形成され得る。
かかる構成においては、上述のように前記リチウム複合酸化物焼結体板に所定の大きさの気孔が所定割合含まれることで、充放電サイクルにおけるリチウムイオンの出入りに伴う結晶格子の伸縮によって発生する応力が、当該気孔によって良好(均一)に開放される。このため、充放電サイクルの繰り返しに伴う粒界クラックの発生が可及的に抑制される。また、前記導電性接合層との界面に含まれる気孔(開気孔)により、接合強度が高まる。このため、充放電サイクルにおけるリチウムイオンの出入りに伴う結晶格子の伸縮による、前記リチウム複合酸化物焼結体板の形状変化を起因とする、上述の接合界面剥離の発生が、良好に抑制される。したがって、本発明によれば、良好なサイクル特性を維持しつつ、高容量化を図ることができる。
図1Aは、本発明の一実施形態が適用されたリチウム二次電池10の概略構成を模式的に示す断面図である。図1Aを参照すると、本実施形態のリチウム二次電池10は、電池ケース11と、セパレータ12と、電解質13と、負極14と、正極15と、を備えている。
図1Bに示されている、正極活物質層15bとしてのリチウム複合酸化物焼結体板は、例えば、以下の製造方法によって、容易かつ確実に形成される。
原料粒子としては、リチウム化合物を含まない、遷移金属(Co,Ni,Mn等)化合物の粒子が用いられる。原料粒子は、適宜、粉砕及び分級され得る。また、目的とする組成に応じて、複数種の原料粒子が適宜混合され得る。さらに、粒成長を促進する目的で、酸化ホウ素,酸化ビスマス,酸化アンチモン,等の低融点酸化物や、塩化ナトリウムや塩化カリウム等の低融点塩化物、ホウケイ酸ガラス等の低融点ガラスが、0.001〜30wt%添加され得る。
原料粒子あるいはその混合物をシート成形することで、「独立した」シート状の成形体が得られる。ここで、「独立した」シート(「自立膜」と称されることもある)とは、他の支持体から独立して単体で取り扱い可能なシートのことをいう(アスペクト比が5以上の薄片も含む)。すなわち、「独立した」シートには、他の支持体(基板等)に固着されて当該支持体と一体化された(分離不能あるいは分離困難となった)ものは含まれない。
上述の成形工程によって得られたシート状の成形体は、後述するリチウム導入工程に先立ち、比較的低温(例えば700〜1200℃)で焼成される。これにより、比較的大きめの気孔が多数含まれる多孔質状のシート状中間焼成体が得られる。かかる仮焼成工程は、例えば、エンボス加工が施されたジルコニア製セッター上に成形体を載置した状態で、大気雰囲気中で行われる。
上述の仮焼成工程によって得られた中間焼成体に、リチウム化合物をふりかけて、熱処理することにより、当該中間焼成体にリチウムが導入される。これにより、「独立した」シート状の正極活物質層用リチウム複合酸化物焼結体板が得られる。かかるリチウム導入工程は、例えば、坩堝中で行われる。
電池特性の評価のために、以下のようにして、CR2032型と同一形状のコインセル型電池を作成した。図2は、かかるコインセル型のリチウム二次電池10の概略構成を示す断面図である。
以下、上述の正極活物質層15bとしてのリチウム複合酸化物焼結体板の具体例、及びかかる具体例の評価結果について、より詳細に説明する。
まず、LiCoO2セラミックス板についての実験例1−1〜1−9の作成条件を、表1に示す。
次に、Li(Ni,Co,Al)O2セラミックス板についての実験例2−1〜2−10の作成条件を、表8に示す。
なお、上述の実施形態や具体例は、上述した通り、出願人が取り敢えず本願の出願時点において最良であると考えた本発明の具現化の一例を単に示したものにすぎないのであって、本発明はもとより上述の実施形態や具体例によって何ら限定されるべきものではない。よって、上述の実施形態や具体例に対して、本発明の本質的部分を変更しない範囲内において、種々の変形が施され得ることは、当然である。
原料粒子としては、合成後の組成が層状岩塩構造を有する正極活物質LiMO2となるように、Li、Co、Ni、Mn等の化合物の粒子を適宜混合したものが用いられる。あるいは、原料粒子として、LiMO2の組成からなるもの(合成済みのもの)を用いることができる。そして、かかる原料粒子に対して、上述の空孔形成材が添加される。
原料粒子と空孔形成材との混合物をシート成形することで、「独立した」シート状の成形体が得られる。かかるシート成形工程は、上述の二段階プロセスと同様である。
上述の成形工程によって得られたシート状の成形体を、空孔を形成しつつ結晶を成長させる目的で、比較的高温(例えば1200℃〜1500℃)で熱処理(焼成)することで、「独立した」シート状の正極活物質層用リチウム複合酸化物焼結体板が得られる。かかる熱処理工程は、例えば、エンボス加工が施されたジルコニア製セッター上に成形体を載置した状態で、酸素雰囲気中で行われ得る。
