Concept of Sodium-Ion Batteries

Overview: Sodium-ion batteries (SIBs) are a type of rechargeable battery that uses sodium ions (Na⁺) to store and release energy. They operate on principles similar to lithium-ion batteries but utilize sodium instead of lithium. This shift in material provides several advantages, particularly in terms of cost and sustainability.

Basic Structure: A sodium-ion battery consists of:

• Anode: Typically made from sodium-containing materials such as hard carbon or sodium titanate.
• Cathode: Made from sodium compounds such as sodium cobalt oxide (NaCoO₂) or sodium iron phosphate (NaFePO₄).
• Electrolyte: Contains sodium salts dissolved in a solvent, enabling the conduction of sodium ions between the electrodes.
• Separator: A porous membrane that prevents direct contact between the anode and cathode while allowing ion flow.

Chemical Reactions

Discharge Reaction: During discharge, the sodium ions move from the anode to the cathode, releasing energy: $\text{Na}_{x}\text{C}_6 + \text{NaCoO}_2 \rightarrow \text{Na}_{x-1}\text{C}_6 + \text{Na}_{1}\text{CoO}_2 + \text{Energy}$

Here, $\text{Na}_{x}\text{C}_6$ represents the sodium intercalated in the anode material, and $\text{NaCoO}_2$ is the sodium cobalt oxide in the cathode. As sodium ions move from the anode to the cathode, energy is released.

Charge Reaction: During charging, the sodium ions move back to the anode from the cathode: $\text{Na}_{1}\text{CoO}_2 + \text{Na}_{x-1}\text{C}_6 \rightarrow \text{Na}_{x}\text{C}_6 + \text{NaCoO}_2 + \text{Energy}$

  pinMode(electrolysisPin, OUTPUT);
}

void loop() {
  // Read sensors
  int tempReading = analogRead(tempSensorPin);
  int voltageReading = analogRead(voltageSensorPin);

  // Convert readings to meaningful units
  float temperature = tempReading * (5.0 / 1023.0) * 100.0; // Example conversion
