Thanks for posting such question that trigger people to bring an energy device as you stated.

What are the factors affecting energy storage materials?

The energy storage materials depend on various factors including the synthesis method, morphology, composition, natural properties ... which decide their energy density, cycle life, cost, safety While taking GCD (galvanostatic charge-discharge) for supercapacitor at what current densities it should be taken?

How can hydrogen be a long-term energy strategy?

1- Establish a role for hydrogen in long-term energy strategies. National, regional and city governments can guide future expectations. Companies should also have clear long-term goals. Key sectors include refining, chemicals, iron and steel, freight and long-distance transport, buildings, and power generation and storage.

Why do scientists use perovskite based energy storage devices?

Scientists can fine-tune the composition of perovskites to enhance their electrical properties, such as conductivity and charge storage capacity. This versatility gives researchers the power to optimize perovskite-based energy storage devices to achieve mind-blowing performance.

Can a fuel cell be used as an energy storage device?

Dear Fariz Maulana, When used as an energy storage device, the fuel cell is combined with a fuel generation device, commonly an electrolyzer, to create a Regenerative Fuel Cell (RFC) system, which can convert electrical energy to a storable fuel and then use this fuel in a fuel cell reaction to provide electricity when needed.
