Photo voltaic photovoltaic panels produce vitality solely whereas the Solar shines, however lighting is required primarily throughout night time. So, the photo voltaic vitality must be saved, which is now typically achieved by lithium-ion batteries.
The lithium-ion batteries have some limitations. For one, value of lithium-ion batteries is growing yr after yr, so these are appropriate for high-priced cellular objects like automobiles and smartphones solely. For stationary functions we have to discover alternate options.
Second, lithium-ion batteries can deal with a couple of thousand cost/discharge cycles solely. This implies the batteries should be changed after about 5 years of use.
Third, re-cycling of lithium-ion batteries is difficult and costly. Additionally, India doesn’t have lithium mines, so we’re utterly depending on imports.
Fourth, lithium-ion batteries additionally use metals like nickel and cobalt. Subsequently, these batteries are usually not environment-friendly. In addition to, lot of mining is required to get these metals.
Therefore, it turns into vital to discover different units for vitality storage. Right here we’ll discover use of supercapacitors for vitality storage for low energy however widespread functions.
This undertaking will probably be printed in a couple of weeks. If you wish to entry it now, discuss with Electronics For You’s February 2023 Subject–print or ezine version.
