Understanding Lithium-ion Batteries
Lithium-ion batteries, which are extensively used in smartphones, laptops, and other portable devices, charge by transporting lithium ions from the negative electrode (anode) to the positive electrode (cathode) and discharge by going the other way. This movement produces electrical energy. The battery’s electrolyte, which is commonly a lithium salt dissolved in a solvent, aids with ion transport. Lithium-ion batteries are widely used for a variety of applications due to their high energy density, lightweight construction, and rechargeability.
Key Components of a lithium-ion Battery
Anode: This is the negative electrode where lithium ions are released during discharging.
Cathode: The positive electrode where lithium ions are absorbed during charging.
Electrolyte: A conductive substance that allows the movement of lithium ions between the anode and cathode.
Separator: A porous membrane that prevents direct contact between the anode and cathode, while allowing the passage of lithium ions.
Collector: Conductive materials that collect and distribute electrical current between the electrodes.
How Charging and Discharging Cycles Affect Battery lifespan
Charging and discharging cycles directly impact the lifespan of a battery, especially lithium-ion batteries commonly used in smartphones and other electronic devices. Each charge and discharge cycle causes a small amount of wear on the battery’s components, particularly the electrodes and electrolyte. Over time, this wear accumulates, leading to degradation in battery capacity and performance. Therefore, minimising the number of charging cycles and avoiding deep discharges can help prolong the battery’s lifespan.

Battery Management System
Battery Management Systems (BMS) are critical components of modern electronic gadgets, particularly those powered by rechargeable lithium-ion batteries. They act as intelligent safeguards by monitoring and controlling many elements of battery operation to assure safety, lifespan, and peak performance.
BMS are essentially powerful microcontrollers that include sensors and software algorithms. Their major duty is to monitor the battery’s charging and discharging procedures while also protecting it from potential damage or failure. Here’s how they operate
Monitoring Battery Parameters
- BMS monitors battery metrics including voltage, current, temperature, and SOC.
- These sensors give real-time data, which allows the BMS to precisely assess the battery’s health and state.
Preventing Overcharging
- Overcharging can lead to excessive heat generation and chemical instability within the battery, ultimately reducing its lifespan and posing safety risks.
- BMS actively regulates the charging process by terminating the charging cycle once the battery reaches its maximum voltage threshold
- They ensure that the charging voltage and current remain within safe limits, preventing overcharging-related damage.
Avoiding Discharging
- Over Discharging happens when the battery is depleted beyond an acceptable voltage level, resulting in irreparable damage and safety risks.
- BMS prevents over discharging by interrupting power flow to the device when the battery voltage falls below a certain threshold.
- This keeps the battery from being overly drained, preserving its capacity and overall health.
Balancing cell Voltage
- In multi-cell battery packs, individual cells may show modest changes in voltage due to capacity or aging.
- BMS uses cell balancing algorithms to equalise voltage across all cells, ensuring uniform charging and discharging.
- This avoids high-voltage cells from being overcharged and increases the battery pack’s usable capacity.
