Description
Ni(OH)2+OH-→NiOOH+H2O+e- … (1)
また負極においては次式(2)で表わされる充電反応が起こる。
M+H2O+e-→MH+OH- … (2)
セパレータ108中を水やOH-イオンは透過するので、電池全体の充電反応は次式(3)で表わされる。
M+Ni(OH)2→MH+NiOOH … (3)
なお、図8においては充電作用について説明したが、放電時は充電反応の逆の放電反応が起こる。
OH-→1/4O2+1/2H2O+e- … (4)
正極で発生した酸素はセパレータを透過して負極に到達し、そこで次の式(5)で示される金属水素化物との反応によって消費される。
MH+1/4O2→M+1/2H2O … (5)
なお、式(5)で減少したMH分は、次の式(6)で示される負極の充電反応により補償される。
M+H2O+e-→MH+OH- … (6)
結局、過充電時の負極の反応は次の式(7)で表わされる。
1/4O2+1/2H2O+e-→OH- … (7)
つまり正極の反応は上述の式(4)で表わされ負極の反応は式(7)で表わされ、正極で発生した酸素は負極で消費されるので、電池全体では見かけ上何の反応も起こっていないことになる。これにより過充電時における酸素による電池内圧の上昇はほとんどない。
Claims (5)

負極と、
前記正極および負極を収容する容器とを備え、
前記容器は、
