Abstract
Description
本明細書で考察するように、アフテンスク鉱及びラムスデル鉱を含む電解二酸化マンガン組成物があり、二酸化マンガンの相のうちの少なくとも一方は、少なくとも一部が非晶質性を示す。例えば、ラムスデル鉱の少なくとも一部が、非晶質性を示すものであってもよい。電解二酸化マンガン組成物は、約30重量%〜約90重量%のアフテンスク鉱を含むことができる。例えば、電解二酸化マンガン組成物は、30重量%、40重量%、50重量%、60重量%、70重量%、80重量%、90重量%のアフテンスク鉱を含むことができる。電解二酸化マンガン組成物は、約10重量%〜約70重量%のラムスデル鉱を含むことができる。例えば、電解二酸化マンガン組成物は、10重量%、20重量%、30重量%、40重量%、50重量%、60重量%、70重量%のラムスデル鉱を含むことができる。アフテンスク鉱とラムスデル鉱の比は、約9:1と約3:9との間とすることができる。このような電解二酸化マンガン組成物は、それぞれ「中性EMD」と称することがある。
中性EMDは、電気分解によって合成される。中性EMDは、粉末またはそれ以外の適切な形態に形成され、処理されてもよい。このような処理済み中性EMDは、本明細書において「NEMD粉末」と称することがある。
NEMD粉末を集電体と組み合わせて電極を形成するようにしてもよい。NEMD粉末を含むか、またはNEMD粉末から形成される電極は、本明細書において「NEMD粉末電極」と称する場合がある。
中性EMDを合成し、集電体上に直接析出させて、中性EMDを含む電極を形成するようにしてもよい。このようにして形成された電極は、この後で電池に組み込まれるようにしてもよい。電池への組み込みに適合する中性EMDの直接的な析出から形成された電極(即ち、電極は電池の外部で製造される)は、本明細書において「現場外生成NEMD電極」と呼ぶ場合がある。
中性EMDを合成し、集電体上に直接析出させて、中性EMDを含む電極を形成するようにしてもよい。このような電極は、電池として直接使用することができるセルの、その場(in-situ)で形成してもよい。このような電極は、本明細書において「現場生成(in-situ)NEMD電極」と呼ぶ場合がある。
本発明は更に、(i)中性EMDを含む電極と、(ii)アノードと、(iii)アノードとカソードとの間のセパレータと、(iv)カソード、アノード、及びセパレータが流体的に接する電解液とを備えた電池に関する。このような電池は、本明細書では「NEMD電池」と称する場合がある。
(i)現在市販されているEMDから形成された電極、(ii)NEMD粉末電極、または(iii)現場外生成NEMD電極を備えた電池を、「電圧カットオフ放電」方式のもとで互いに比較する。この方式において、セルは、低い方の特定のカットオフ電圧に達するまで、定電流で放電される(定電流放電)。その後、直ちに、セルは、高い方のカットオフ電圧に達するまで、同じ電流で充電(定電流充電)される。次に、セルは、更なる充電のために、一定時間にわたり、同じ高い方のカットオフ電圧(定電位充電)に保持される。
現場外生成NEMD電極を備えた電池とNEMD粉末電極を備えた電池とを、以下に記載する「定電流カットオフ放電」方式のもとで互いに比較する。この方式において、定電流放電ステップは、100mAh・g−1の容量に達すると終了する。この容量は、一般に、セル電圧が1.1V(方式1で使用)に達する前に得られる。100mAh・g−1は、産業上の目標を反映するように選択される。但し、別の実験的試験では、これ以外の容量の評価を行うことができる。
現場外生成EMD電極またはNEMD粉末電極を備えた電池の更なる例を以下の表4に示す。
図9を参照すると、現在市販されているEMD(即ち、エラケム)及び中性EMD(即ち、ISA019_02、表1参照)のXRDディフラクトグラムの比較が提示されている。図9の破線プロットを参照すると、約22°(ラムスデル鉱に帰属可能)、約37°(アフテンスク鉱に帰属可能)、約42°(アフテンスク鉱に帰属可能)、約56°(アフテンスク鉱に帰属可能)、約67°(アフテンスク鉱に帰属可能)に発生したピークがある。
本明細書で論じられるいずれの態様または実施形態のいずれの部分も、本明細書で論じられる別のいずれかの態様または実施形態のいずれかの部分と、一緒に実施し、または組み合わせてもよいと考えられる。上述のとおり、具体的な実施形態について説明したが、別の実施形態も可能であり、本発明に含まれることを理解されたい。上述の実施形態の変更及び調整が可能であることは、示していなくても当業者に明らかであろう。
