Hydrogel alkaline electrolytes for Ni-MH batteries
Journal Title: CHEMIK nauka-technika-rynek - Year 2015, Vol 69, Issue 12
Abstract
Several years ago chemical power sources supplied power exclusively with application of liquid electrolytes that have high ionic conductivity, thus allowing quick ion migration between opposite side electrodes. Apart from advantages, liquid electrolytes have also numerous disadvantages. Using liquid electrolytes in chemical power sources can be dangerous both for its direct user, as well as for the environment. In 1978, the team of Prof. Armand has proven that liquid electrolyte in batteries can be successfully replaced with polymer electrolyte, which has at the same time high ionic conductivity, thermal and mechanical stability and high operational safety. Moreover, application of polymer electrolyte allows complete elimination of separator from the electrochemical system, as it forms itself specific interelectrode barrier that prevents direct electron flow between opposite sign electrodes
