Japanese Paleolithic are a technology associated in the rest of the world with the beginning of the Neolithic around 10,000 BC. It is not known why such tools were created so early in Japan. Because of this originality, the Japanese Paleolithic period in Japan does not exactly match the traditional definition of Paleolithic based on stone technology (chipped stone tools). Japanese Paleolithic tool implements thus display Mesolithic and Neolithic traits as early as 30,000 BC. The Paleolithic populations of Japan, as well as the later Jōmon populations, appear to relate to an ancient Paleo-Asian group which occupied large parts of Asia before
Lithium-ion battery Sony in 1990. The cell's energy is equal to the voltage times the charge. Each gram of lithium represents Faraday's constant/6.941 or 13,901 coulombs. At 3 V, this gives 41.7 kJ per gram of lithium, or 11.6 kWh per kg. This is a bit more than the heat of combustion of gasoline, but does not consider the other materials that go into a lithium battery and that make lithium batteries many times heavier per unit of energy. The cell voltages given in the Electrochemistry section are larger than the potential at which aqueous solutions will electrolyze. Liquid electrolytes in lithium-ion
