Pacific Maple is also known as Philippines Mahogany, Luan and Luaun. When made into plywood, it is usually significantly lighter than Hoop Pine and sometimes almost as light as Gaboon. This varies according to exactly which subspecies of Shorea was used for the veneers in the marine plywood.
Lithium cobalt oxide consists of layers of lithium (show here as purple spheres) that lie between slabs formed by cobalt and oxygen atoms (shown here as connected red and blue spheres). In a lithium-ion battery, the lithium ion is the cation that travels from anode to cathode. Lithium (Li) is easily ionized to form Li+ plus one electron. The electrolyte is typically a combination of lithium salts, such as LiPF6, LiBF4, or LiClO4, in an organic solvent, such as ether.
A positive ion is called an optimistic would-be atom and a negative ion is called a pessimistic (and courting disappointment) soon-to-be atomâ¦. No, seriously they are , respectively, cations (positive) and anions (negative) Perhaps confusingly, the positive ion has lost something - an electron (sub-atomic particle carrying a one-unit negative charge) - whilst the negative ion has gained one (compared to the neutral state of the atom, in which the positive and negative charges are balanced).
