 Now a days Battery breakthrough for electric cars. Long-lasting, quick-charging batteries are essential to the expansion of the electric vehicle market, but today’s lithium-ion batteries fall short of what’s needed — they’re too heavy, too expensive and take too long to charge. For decades, researchers have tried to harness the potential of solid-state, lithium-metal batteries, which hold substantially more energy in the same volume and charge in a fraction of the time compared to traditional lithium-ion batteries.   Electricity storage is both complicated and expensive. Electricity has to be converted into another form of energy then converted back into electrical energy before it can be reused. Scientists have been trying to crack the electricity storage code for over 150 years now. Despite their efforts, the two main storage technologies employed today: lead-acid batteries (invented in 1859) and pumped hydro storage (first pumped storage station was opened in Switzerland ...
