Higher capacity,higher voltage,
and longer life.
It is different from conventional matel-base
The dry cell was introduced in 1890.
In 1970,The development of plastic batteries began with an accident.
The plastic batteries was commercially
available in 1987.
FIRST PLASIC BATTERY
FIRST PLASIC BATTERYThe outer casing is made up of strong glass. Anode & cathode are attached to the separate small network of copper wires. each of this network is connected to the positive &negative outer terminals of battery.
one separate is also provided between anode &cathode to avoid any possible short circuit.
These all three layers are immersed in to the iodine, which behaves as an electrolyte. this electrolyte itself contains positive &negative ions, due to which the electrodes are not bound to give their electrons. this electrolyte just does the doping.
