Moisture-resistant and anti-corrosive energy storage devices and associated methods

A cell of an energy storage device, comprising:

• a cap plate forming a first surface;
• an electrical terminal exposed through the first surface and configured to electrically couple to a protective circuit board;
• and
• a protective coating on at least a portion of the first surface, the protective coating limiting exposure of a current collector of a cathode plate or associated with a cathode plate to moisture and corrosive agents, including electrolytes, corrosive gases and dust.

A method for preventing exposure of an energy storage device to moisture and corrosive agents, comprising:

• applying a first protective coating to at least a portion of at least one surface of a cell of an energy storage device having a first electrical terminal, the first protective coating comprising a moisture resistant coating formed from a material that will withstand exposure to corrosive agents, including electrolytes, corrosive gases and dust;
• applying a second protective coating to at least a portion of at least one surface of a circuit board having a second electrical terminal, the second protective coating comprising a moisture resistant coating formed from a material that will withstand exposure to corrosive agents, including electrolytes, corrosive gases and dust;
• and
• electrically coupling the first electrical terminal to the second electrical terminal.
