Electric Motorcycle Battery development and manufacturing, plus problems and solutions
When fuel and air burn inside the cylinder of an internal-combustion engine, the energy being released comes from the electronic bonds that bind atoms together to form molecules. The bond energy of unburned hydrocarbon fuel and diatomic oxygen from the air is higher than that of the products of complete combustion, which are water and carbon dioxide. Upon combustion, this energy difference appears (mainly) as heat. This heat raises the pressure of the gases in the cylinder, driving the piston downward to turn the engine’s crankshaft. The very same kind of electronic bond energy stores and delivers the power we take from batteries. A battery at its simplest consists of a positive and a negative electrode, exposed to an electrolyte. In the case of today’s powerful Lithium-ion batteries , the electrolyte consists of Lithium salts dissolved in an organic liquid. Just as table salt—sodium chloride or NaCl—separates into oppositely charged sodium and chlorine ions when dissolve
