Lithium-ion batteries are rechargeable and are the ones used in laptops, cell phones, etc. Lithium batteries can discharge quickly and have a high energy storage capacity, so if you have a short circuit, it can generate a lot of heat and vaporize the water in the electrolyte causing an explosion. This is why many of them today have either vent or a current limiting device built in. For the much the same reasons, a lithium-ion battery has the same protection, although the energy storage capacity on a unit volume is not as high as lithium batteries. I would not characterize either battery as "unstable" or "ready to explode". As with any technology, they have limitations that must be realized. I've seen a transformer that plugs into the wall short circuit and cause a fire. If you have energy, this stuff can happen."

On Earth, lithium is widely distributed, but because of its reactivity does not occur in its free form. In keeping with the origin of its name, lithium forms a minor part of almost all igneous rocks and is also found in many natural brines. Lithium is the thirty-first most abundant element, contained particularly in the minerals spodumene, lepidolite, petalite, and amblygonite. On average, Earth's crust contains 65 parts per million (ppm) lithium. Beryllium Beryllium is an essential constituent of about 100 out of about 4000 known minerals, the most important of which are bertrandite (Be4Si2O7(OH)2), beryl (Al2Be3Si6O18), chrysoberyl (Al2BeO4), and phenakite (Be2SiO4). Precious forms of beryl are aquamarine and emerald. Boron Turkey and the United States are the world's largest producers of boron. Turkey has almost 63% of the world’s boron potential and boron reserves.[5] Boron does not appear in nature in elemental form but is found combined in borax, boric acid, colemanite, kernite, ulexite and borates. Boric acid is sometimes found in volcanic spring waters. Ulexite is a borate mineral that naturally has properties of fiber optics. Carbon Carbon is the fourth most abundant chemical element in the universe by mass, after hydrogen, helium, and oxygen (see chemical element). Carbon is abundant in the sun, stars, comets, and in the atmospheres of most planets. Some meteorites contain microscopic diamonds that were formed when the solar system was still a protoplanetary disk. In combination with other elements, carbon is found in the earth's atmosphere (around 810 gigatonnes) and dissolved in all water bodies (around 36000 gigatonnes). Around 1900 gigatonnes are present in the biosphere. Hydrocarbons (such as coal, petroleum, and natural gas) contain carbon as well--coal "reserves" (not "resources") amount to around 1000 gigatonnes, and oil reserves around 150 gigatonnes. With smaller amounts of calcium, magnesium, and iron, carbon is a major component of very large masses carbonate rock (limestone, dolomite, marble etc.). Graphite is found in large quantities in New York and Texas, the United States; Russia; Mexico; Greenland and India. Natural diamonds occur in the mineral kimberlite found in ancient volcanic "necks," or "pipes". Most diamond deposits are in Africa, notably in South Africa, Namibia, Botswana, the Republic of the Congo and Sierra Leone. There are also deposits in Arkansas, Canada, the Russian Arctic, Brazil and in Northern and Western Australia. Nitrogen Nitrogen is the largest single component of the Earth's atmosphere (78.082% by volume, 75.3% by weight). 14N is created as part of the fusion processes in stars, and is estimated to be the 7th most abundant chemical element (by mass) in our universe. Compounds that contain this element have been observed by astronomers, and molecular nitrogen has been detected in interstellar space by David Knauth and coworkers using the Far Ultraviolet Spectroscopic Explorer. Molecular nitrogen is a major constituent of Titan's thick atmosphere, and occurs in trace amounts of other planetary atmospheres. Nitrogen is present in all living tissues as proteins, nucleic acids and other molecules. It is a large component of animal waste (for example, guano), usually in the form of urea, uric acid, and compounds of these nitrogenous products."
