Pollution will not be generated, however the water battery aluminum substrate is easy failure, and conductive copper silk screen is at high cost, cell output is paid no attention to
Think, affects practicability.CN2377685 discloses a kind of salt battery between primary battery and battery, this battery
Do not need charging equipment, generated electrolyte is free from environmental pollution, can in a dry environment long-term preservation it is spare, with battery
It compares, the salt battery is small in size, light-weight, non-corrosive, long service life, anode plate is only needed to change, with dry cell
It compares, expense reduces 70%, in non-transformer, 6W compact electric apparatus below can be driven, however the salt battery
Cathode plate is made of electrically conductive graphite, and aluminium anodes plate is with high costs using magnesium metal, and the electrical power of battery is lower.
Existing aluminium-air cell is substantially a kind of chemical reaction equipment for discharging electric energy, cannot charge, need repeatedly
Replacement aluminium electrode can just work on, and in real work, replacement aluminium electrode, which usually requires multiple person cooperational, to be completed, time-consuming to take
Power.Therefore, it is necessary to develop a kind of new battery, keep the replacement of aluminium electrode more convenient, or even can be as automobile fuel filler
Realize the replacement of aluminium electrode.
