Electrode material improves flowless zinc-bromine batteries
The flawless zinc-bromine battery (FLZBB) is a promising alternative to flammable lithium-ion batteries because it uses non-flammable electrolytes. However, it suffers from self-discharge due to the crossover of active materials, generated at the positive graphite felt (GF) electrode, to the negative electrode, significantly affecting performance. Now, researchers have developed a novel nitrogen-doped mesoporous carbon-coated GF…
Solid-state batteries could change how we use power devices
With so many batteries, from cell phones to EVs, that are dependent on lithium, an alternative is always welcome. Solid-state chemistries could significantly reduce the risk of overheating and fire. We’ve become dependent on lithium-ion (Li-ion) batteries to power cell phones, EVs, and everything in between. Today’s Li-ion batteries can produce low and high voltages.…
