Dry-cell batteries and liquid battery

Dry-cell batteries and liquid batteries distinction is limited to the period early cell development. First battery electrolyte-filled glass containers and two electrodes. Later made the basis of Pasty electrolyte battery, also known as dry-cell batteries. 

There is still "fluid" battery. In general are very large in size. Such as those for uninterruptible power supply of large stationary lead-acid batteries or lead-acid batteries used with solar cells. For mobile devices, some use a sealed, maintenance-free lead-acid battery, this battery has been successfully used for many years, one of the electrolyte is sulfuric acid is made of silica gel fixed glass fiber separator or pay.
