the prototype team use the nickel-cadmium for the tests, and
we'll concentrate on developing the nickel-metal hydride.
We'll have to adjust the battery to the prototype's data."
Dark clouds were appearing on the horizon for the battery
group.
Because battery output is determined by the volume of
the active materials, the pole plates were rolled out as
thinly and widely as possible to achieve higher power.
In order to fit a pole plate inside the same case as a size A
battery, it is rolled up. Batteries were made over and over
again, and tests were run every time. The group tried to
achieve higher power output with this method.
In order to achieve the other target of instantaneously
charging and discharging power, the group tried to figure
out how to lower the resistance on the connection
terminal from which electric current is withdrawn.
When this terminal has high resistance, heat is produced, and
electric energy is lost in the form of heat. When draining
water from a tank, it takes a long time to empty the tank if
the faucet is small. It was the same idea as trying not to let
this faucet clog up. Matsushita's know-how was used for the
welding method. By focusing on improving these two things,
performance began to improve by the next spring.
