What Is A Solid State Battery?

By Michael Bizzaco – BGR

Many of the best modern electric vehicles (EVs) are more energy-efficient than ever, especially now that top manufacturers like Honda and Toyota are already investing in the next generation of EV power. We’re referring to solid-state batteries, an evolving technology that could yield significant gains for EV owners in terms of driving range and overall performance. While there’s a debate within the automotive industry as to what exactly constitutes a solid-state battery, the basics are as follows: A traditional EV cell uses liquid electrolytes as a passageway for ions to travel between a battery’s cathode (negative terminal) and anode (positive terminal).
