摘要:
A hydrogen storage material which is characterized by having, as a cast alloy, a flaky or similar shape with a thickness of 50 to 500 &mgr;m and showing such crystallite orientation that the X-ray diffraction pattern has an intensity ratio of plane indices (002)/(200) of 2 to 10 as measured with the cooled surface of the flaky cast alloy being in parallel with a mount, and a process of producing the same.
摘要:
A manganese-nickel mixed hydroxide for battery active material comprising a manganese-containing mixed hydroxide having a coated layer composed of a mixed-oxide of nickel and cobalt, to provide an excellent discharging property and allows one to achieve an improvement in the discharge utilization when it is used as an electrode material for secondary batteries.
