It weighs very little, but still carries more energy than other batteries of the same size. They are based on charged atomic small particles and ions. Although not very explosive, nitroglycerin is sensitive to the movement of chaos.
But they have passed the past two decades, far from the days when a lack of stability meant they could not be trusted outside the laboratory. Lithium-ion batteries have entered the mainstream. If you are careful, then choose the batteries who can do unique work and gave the best performance that other batteries cannot do.
Light lithium metal-based batteries have been the subject of research since 1912 but reached commercial status until the 1970s, and not all batteries at that time could be recharged. Because lithium metals are highly volatile, lithium metal batteries must be abandoned and replaced with lithium-ion batteries before charging is possible.
Many Corporations introduced the first lithium-ion battery that can be recharged in 1991 and is now an optional rechargeable battery.
Competition, nickel-cadmium batteries, only have half the energy density of lithium-ion batteries. Nickel batteries are also far more supportive than lithium-ion batteries, which do not require a full discharge before charging. And if lithium-ion batteries are thrown away, they are far less harmful to the environment than nickel batteries.
