Abstract: An electrochemical cell includes an anode, a cathode, a separator, and a liquid electrolyte. The cathode includes an active material, a conductive material, a binder, and a gelling powder. The separator is arranged between the anode and the cathode. The separator is configured to prevent direct contact between the anode and the cathode. The liquid electrolyte transports positively charged ions between the cathode and the anode.

Abstract: A charging voltage of a battery may be determined based on an age of the battery. The age and charging voltage can be determined by a computing apparatus or a battery management system. The determined charging voltage may increase as the age of the battery increases. The battery may be charged at the charging voltage for the duration of a charge cycle. The battery may be charged using a charger.

Abstract: A rechargeable lithium-ion battery includes a positive electrode enabling fast charging. A negative electrode has a first active material including Li4Ti5O12. A positive electrode includes a second active material including LiCoO2. The positive electrode further includes a carbon conductive agent and a binder. A weight ratio of the carbon conductive agent to the binder is in a range of about 2:3 to about 3:2.

Abstract: At least one electrochemical cell is charged to a predetermined voltage of the electrochemical cell using an external power source. A charging current of the at least one electrochemical cell is monitored. An increase in the charging current is detected at the predetermined voltage of the at least one electrochemical cell. It is determined that the at least one electrochemical cell is in danger of experiencing a performance decrease based on the detected increase in the charging current.
