Description
前記組電池が収容される電子伝導性の筐体と
を具備する電池パックであって、
端面が前記筐体の壁面と対向する封止部が折り返されることにより、前記封止部の前記端面が前記筐体から絶縁されていることを特徴とする。
図1に示すように、第1の実施形態に係る電池パックは、電子伝導性を有する筐体1と、筐体1内に収納された組電池2とを備える。筐体1は、矩形の筒状で、内部が仕切板1a,1bによって3つの空間に仕切られている。各空間には、扁平型非水電解質電池31〜33がそれぞれ収納されている。筐体1を構成する電子伝導性材料としては、例えば、アルミニウム、アルミニウム合金、鉄、ステンレスなどの金属を挙げることができる。組電池の軽量化の観点から、アルミニウム、アルミニウム合金が望ましい。金属製の筐体は、組電池の幅や厚みが増加するのを抑制して電池パックを十分に小型化して体積エネルギー密度を高くすることができる。また、筐体の剛性が高くなるため、電池パックの落下及び振動に対する強度も大きくすることができる。筐体の板厚は、組電池を構成するセルの数量にもよるが、0.2mm〜2mmの範囲が望ましい。
第2の実施形態に係る電池パックは、封止部端面の絶縁方法が異なること以外は、前述した第1の実施形態に係る電池パックと同様な構成を有する。
第3の実施形態に係る電池パックは、電池を平置きに配置した状態で直列に接続した組電池を備えている。
Claims (3)
- アルミニウムもしくはアルミニウム合金の層を備えたラミネートフィルム製で、周縁の少なくとも一部に封止部を有する容器と、前記容器内に収納され、リチウム吸蔵電位(開回路)がリチウム金属電位に対して0.4V以上となる負極活物質を含む電極群とを具備する複数の扁平型非水電解質電池が直列接続されたユニットを備える組電池と、
前記組電池が収容される電子伝導性の筐体と
を具備する電池パックであって、
端面が前記筐体の壁面と対向する封止部が折り返されることにより、前記封止部の前記端面が前記筐体から絶縁されていることを特徴とする電池パック。 - 前記封止部の前記端面が絶縁部材で被覆されていることを特徴とする請求項1記載の電池パック。
- 前記絶縁部材は、絶縁剤の塗布もしくは絶縁剤への浸漬により形成されるか、絶縁紙もしくは絶縁テープあるいは構造体からなることを特徴とする請求項2記載の電池パック。
