HOW ELECTRIC BATTERY STORES ENERGY?
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.
The flow of electrons provides an electric current that can be used to do work. To balance the flow of electrons, charged ions also flow through an electrolyte solution that is in contact with both electrodes.
Different electrodes and electrolytes produce different chemical reactions that affect how the battery works, how much energy it can store and its voltage. .

WHY CAN’T WE REMEMBER OUR DREAMS?
WE FORGET almost all dreams soon after waking up. Our forgetfulness is generally attributed to neurochemical conditions in the brain that occur during REM sleep, a phase of sleep characterized by rapid eye movements and dreaming. But that may not be the whole story.
Perhaps the most compelling explanation is the absence of the hormone norepinephrine in the cerebral cortex, a brain region that plays a key role in memory, thought, language and consciousness
Although most dreams vanish, certain ones tend to remain. These dreams were so beautiful or bizarre, they captured our attention and increased activity in our dorsolateral prefrontal cortex (DLPFC). Thus, the more impressive your dream or thought, the more likely you are to remember it.
