Description
(1)他の二次電池と比較して体積エネルギー密度、重量エネルギー密度が小さい。
(2)過放電に弱く、過放電が発生すると性能が大きく低下する。
(3)軽量化と耐久性の両立が課題とされている(例えば、特許文献3)。
フッ素ガス処理は、例えば、不活性ガスで希釈したフッ素ガスに、気密空間の中で不織布をさらすことにより不織布の繊維表面を親水化することができる。また、金属酸化物としては例えば、チタン酸化物、ジルコニウム酸化物、イットリウム酸化物、ハフニウム酸化物、酸化カルシウム、酸化マグネシウム、酸化スカンジウムなどが挙げられる。ジルコニア(ZrO2)もしくは酸化イットリウム(Y2O3)が好ましい。金属酸化物は親水性を有しており、かつ、水素により劣化しにくいから長期にわたって親水性を保持し、電解液のドライアウトを抑制することが可能である。
ここにネルンストの式は、V=V0+αlog(c1/c2)であって、V;電極電位、V0;標準電極電位、α;定数、c1/c2;濃度比である。
水素ガスの発生につれて電池の端子電圧は緩やかに上昇し、ついには充電電圧と等しくなって充電電流は流れなくなり充電は停止する。すなわち充電が進めば電池電位が上昇して、直流電源の電圧と等しくなれば充電電流は流れなくなり、事実上、充電は停止する。
