Battery anode with alternating active layers

A method of manufacturing an anode for a rechargeable battery cell, the method comprising:

• providing a current collector;
• and
• depositing onto the current collector an active layer having discrete first and second material sections, including arranging in an alternating pattern and aligning perpendicular to the current collector the first and second material sections to generate the anode;
• wherein:
• the active layer is defined by a length, a width, and a height;
• the alternating pattern is a chessboard pattern of the first and second material sections, such that each of the discrete first material sections and second material sections has a column structure;
• and
• arranging in the alternating pattern and aligning perpendicular to the current collector each of the discrete first and second material sections includes fitting multiple first and multiple second material sections across each of the length and the width of the active layer.

An anode for a rechargeable battery cell, comprising:

• an electrode substrate;
• and
• a current collector fixed to the electrode substrate;
• and
• an active layer defined by a length, a width, and a height arranged on the current collector and having discrete graphite-containing sections and silicon-containing sections arranged in an alternating pattern;
• wherein:
• each of the graphite-containing and silicon-containing sections is aligned perpendicular to the current collector;
• the alternating pattern is a chessboard pattern and each of the discrete graphite-containing material sections and silicon-containing material sections has a column structure, such that multiple graphite-containing and the multiple silicon-containing material sections fit across each of the length and the width of the active layer;
• and
• the active layer is configured to intercalate lithium ions during charging of the battery cell and de-intercalate the lithium ions during discharging of the battery cell.
