Improved lithium-ion batteries in which the cathode comprises particles that include transition metal grains having a grain size no greater than about 50 nanometers; and lithium-containing grains selected from the group consisting of lithium oxides, lithium sulfides, lithium halides, and combinations thereof. The network node determines a set of feature values to be used as input to a classifier based on the voting request. Data is cached starting at a beginning of the caching partition. A group of observers then analyze the lighting condition signal. The holding mechanism mates with the receiving area to connect with the handle portion. At a timing at which a period of time corresponding to one period of oscillation generated on an objective lens of the pickup has passed after moving the pickup in the direction opposite to the pickup moving direction, the pickup is moved in the pickup moving direction.
