Description
正極14は、正極集電体14bとこれに一体となる正極合材層14cとを有しており、正極合材層14cには正極活物質としてのバナジウム酸化物(例えば、五酸化バナジウムやリチウムを含有した五酸化バナジウム)が含有されている。この正極活物質としては、イオンを可逆的にドープ・脱ドープできるものであれば特に限定されることはなく、例えば金属酸化物、活性炭、導電性高分子、ポリアセン系物質等を挙げることができる。
負極15は、負極集電体15bとこれに一体となる負極合材層15cとを有しており、負極合材層15cには負極活物質としての天然黒鉛が含有されている。この負極活物質としては、イオンを可逆的にドープ・脱ドープできるものであれば特に限定されることはなく、例えばグラファイト、種々の炭素材料、ポリアセン系物質、錫酸化物、珪素酸化物等を挙げることができる。特に、黒鉛や易黒鉛化炭素材料は厚膜化可能であるとともにサイクル特性が良好な為、好ましい。
正極集電体14bおよび負極集電体15bとしては、表裏面を貫く貫通孔14a,15aを備えているものが好適であり、例えばエキスパンドメタル、パンチングメタル、網、発泡体等を挙げることができる。貫通孔の形状や個数等については、特に限定されることはなく、リチウムイオンの移動を阻害しないものであれば適宜設定することが可能である。また、負極集電体15bおよび正極集電体14bの材質としては、一般に有機電解質電池に提案されている種々の材質を用いることが可能である。例えば、正極集電体14bの材質として、アルミニウム、ステンレス鋼等を用いることができ、負極集電体15bの材質として、ステンレス鋼、銅、ニッケル等を用いることができる。
リチウム極16は、ステンレスメッシュ等の導電性多孔体からなるリチウム極集電体16aと、これに貼り付けられた金属リチウム16bとによって構成されている。また、リチウムイオン供給源を構成する金属リチウム16bに代えて、リチウム−アルミニウム合金のように、リチウムイオンを供給することが可能な合金等を用いるようにしても良い。さらに、リチウム極集電体16aを負極集電体15bや正極集電体14bと同様の材料を用いて形成することも可能である。さらに、金属リチウム16bはリチウムイオンを放出しながら減少し、最終的には全量が正極合材層14cや負極合材層15cに対してドープされることになるが、金属リチウム16bを多めに配置して一部を蓄電デバイス10内に残存させるようにしても良い。
セパレータ13としては、電解液、正極活物質、負極活物質等に対して耐久性があり、連通気孔を有する電子伝導性のない多孔質体等を用いることができる。通常は、ガラス繊維、ポリエチレンあるいはポリプロピレン等からなる布、不織布あるいは多孔体が用いられる。セパレータ13の厚みは、電池の内部抵抗を小さくするために薄い方が好ましいが、電解液の保持量、流通性、強度等を勘案して適宜設定することができる。このセパレータ13には後述する電解液が含浸されている。
電解液としては、高電圧でも電気分解を起こさないという点、リチウムイオンが安定に存在できるという点から、リチウム塩を含む非プロトン性有機溶媒を用いることが好ましい。非プロトン性有機溶媒としては、例えばエチレンカーボネート、プロピレンカーボネート、ジメチルカーボネート、ジエチルカーボネート、γ−ブチロラクトン、アセトニトリル、ジメトキシエタン、テトラヒドロフラン、ジオキソラン、塩化メチレン、スルホラン等を単独あるいは混合した溶媒が挙げられる。また、リチウム塩としては、例えばCF3SO3Li、C4F9SO8Li、(CF3SO2)2NLi、(CF3SO2)3CLi、LiBF4、LiPF6、LiClO4等が挙げられる。
外装容器としては、一般に電池に用いられている種々の材質を用いることができ、鉄やアルミニウム等の金属材料を使用しても良く、フィルム材料等を使用しても良い。また、外装容器の形状についても特に限定されることはなく、円筒型や角型など用途に応じて適宜選択することが可能であるが、蓄電デバイス10の小型化や軽量化の観点からは、アルミニウムのラミネートフィルム11を用いたフィルム型の外装容器を用いることが好ましい。一般的には、外側にナイロンフィルム、中心にアルミニウム箔、内側に変性ポリプロピレン等の接着層を有した3層ラミネートフィルムが用いられている。また、ラミネートフィルム11は、中に入る電極等のサイズに合わせて深絞りされているのが一般的であり、深絞りされるラミネートフィルム11内に三極積層ユニット17を設置して電解液を注入した後、ラミネートフィルム11の外周部は熱溶着等によって封止される構成となっている。
層状結晶性物質としての五酸化バナジウム(V2O5)200gと、水溶性リチウムイオン源として半モル量の硫化リチウム(Li2S)30gと、硫黄含有伝導性ポリマー用のモノマーとして五酸化バナジウムに対して0.6モル量の3,4−エチレンジオキシチオフェン(EDOT)100gとを、水5l中に懸濁して懸濁液を得た。そして、得られた懸濁液を24時間に渡って加熱攪拌還流した。攪拌終了後、吸引濾過を行い、懸濁液から固形分を除去した。この固形分は、硫黄と3,4−エチレンジオキシチオフェンの重合物であった。固形分が除去された濾液を130℃の乾燥雰囲気下で四流体ノズルを用いて、噴霧乾燥することで黒色の球状粒子を得た。この生成物を150℃で真空乾燥して正極活物質を得た。図10に示すように、この正極活物質をX線結晶回折解析した結果、回折角2θ=10°付近にピークを有することが確認された。また、ICP分析によりリチウムイオンが取り込まれていることが確認された。元素分析により炭素量が1%以下であることが確認された。これを透過電子顕微鏡で観察した結果を前掲の図9に示した。図9から層長が5nm以上25nm以下となる層状結晶粒がランダムに集合して存在し、面積率で99%得られていることが確認された。
図12は比較例用に組み立てた従来の蓄電デバイスの内部構造を概略的に示す断面図である。図12に示すように、セパレータとしてのポリオレフィン系微多孔膜を介して、実施例1で用いた正極12枚、負極13枚(内片面塗布2枚)を積層した。そして、更にセパレータを介して、ステンレス多孔箔に金属リチウムを貼り付けたリチウム極を最外層に配置して、正極、負極、リチウム極およびセパレータからなる三極積層ユニットを作製した。なお、負極の端子溶接部にはリチウム極集電体であるステンレス鋼多孔箔の端子溶接部が抵抗溶接されており、実施例1で使用した蓄電デバイスは3極(正極,負極,リチウム極)であるのに対し、比較例1で使用する蓄電デバイスは2極(正極,負極)の蓄電デバイスとなっている。続いて、三極積層ユニットをアルミニウムのラミネートフィルムでパッケージングし、ホウフッ化リチウム(LiBF4)を1モル/lで溶解したエチレンカーボネート(EC)/ジエチルカーボネート(DEC)=1/3(重量比)の電解液を注入した。この電解液の注入によって負極に対するリチウムイオンのドープを開始させ、負極に対して所定量(Q1+Q2)のリチウムイオンをドープさせた。この結果を図11に示す。図11に示すように、負極のみに対してリチウムイオンをドープさせた場合には、負極電位の低下に伴ってドープ速度が低下するため、約35時間のドーピング時間が必要であることが確認された。このように、実施例1のような短いドーピング時間ではリチウムイオンをドープすることが不可能であった。
