A miniature electrochemical cell having a total volume that is less than 0.5 cc is described. The cell casing is formed by joining two ceramic casing halves together. One or both casing halves are machined from ceramic to provide a recess that is sized and shaped to contain the electrode assembly. The opposite polarity terminals are metal feedthroughs, such as of gold, and are formed by brazing gold into openings machined into one or both of ceramic casing halves. A thin film metallization, such as of titanium, contacts an edge periphery of each ceramic casing half. The first ceramic casing half is moved into registry with the second ceramic casing half so that the first and second ring-shaped metallizations contact each other. Then, a laser welds through one of the casing halves being a substantially transparent ceramic, for example sapphire, to braze the first and second ring-shaped metallizations to each other to thereby join the first and second casing halves together to form a casing housing the electrode assembly. A solid electrolyte (Li.sub.xPO.sub.yN.sub.z) activates the electrode assembly.

In a battery casing a metal negative electrode that contains metal serving as a negative electrode active material and an air electrode are arranged so as to face each other in a state where at least a part of the metal negative electrode and the air electrode is immersed in an electrolytic solution inside a casing. The metal negative electrode is housed in a negative electrode housing in the casing. A separator separating the metal negative electrode and the air electrode is arranged at a side surface of the negative electrode housing. An opening through which inside of the negative electrode housing and outside of the negative electrode housing communicate with each other is provided on an upper surface of the negative electrode housing.

A lithium-ion battery module includes a housing having a plurality of partitions configured to define a plurality of compartments within a housing. The battery module also includes a lithium-ion cell element provided in each of the compartments of the housing. The battery module further includes a cover coupled to the housing and configured to route electrolyte into each of the compartments. The cover is also configured to seal the compartments of the housing.

Battery life cycle management is facilited with distinct visual cues of colors and color-coded combinations. The color-codes enable battery types and characteristics over the course of the life of the battery to be determined. The color-codes are based on a color system that indicates a performance rating of the batteries. A system for managing the color-coded batteries selects color-coded batteries for use based upon color, maintaining color based functionality, and color-coded battery indication for destruction of the battery at the end of its life cycle.

A miniature electrochemical cell having a volume of less than 0.5 cc is described. The cell casing comprises an open-ended ceramic container having a via hole providing an electrically conductive pathway extending through the container. A metal lid closes the open-end of the container. An electrode assembly housed inside the casing comprises an anode current collector deposited on an inner surface of the ceramic container in contact with the electrically conductive pathway in the via hole. An anode active material contacts the current collector and a cathode active material contacts the metal lid. A separator is disposed between the anode and cathode active materials. That way, the electrically conductive pathway serves as a negative terminal, and the lid, electrically isolated from the conductive pathway by the ceramic container, serves as a positive terminal. The negative and positive terminals are configured for electrical connection to a load.
