BQ25185 all-in-one Li-Poly board with 3.3V out 🔋🌞⚡

We had a previous version of this 3.3V buck output board with an MCP73831, but now we've replaced it with a BQ25185, which makes it a little more flexible: Vin can be up to 18V, and solar panels will work, too. There's also a power path and 4.5V regulated output. This charger chip can handle LiFePO4, but for that chip, we might swap the buck for a buck-boost or a boost / LDO to get the solid 3.3V output. Coming soon.

Understanding Lithium-Ion (Li-ion) and Lithium Polymer (LiPo) Batteries

Lithium-ion (Li-ion) and Lithium Polymer (LiPo) batteries are two popular types of rechargeable batteries widely used in various applications, from consumer electronics to electric vehicles. While they share some commonalities, such as utilizing lithium, they differ significantly in their chemical composition, construction, and performance characteristics.

1. Lithium-Ion (Li-ion) Batteries Electrolyte

Li-ion batteries use a liquid electrolyte, typically a lithium salt dissolved in an organic solvent. This facilitates the movement of lithium ions between the positive and negative electrodes during charging and discharging.

Cell Design

Li-ion batteries are often housed in rigid cylindrical or prismatic metal cases, which provide robust physical protection to their internal components.

Advantages Energy Density: Li-ion batteries offer high energy density, allowing them to store significant energy relative to their weight. This makes them ideal for devices requiring substantial power in compact sizes. Long Lifespan: They have a long cycle life, meaning they can be charged and discharged many times before noticeable capacity degradation occurs. Stability: Li-ion batteries exhibit good stability and safety, often featuring built-in protection circuits to prevent overcharging and overheating.

2. Lithium Polymer (LiPo) Batteries

Electrolyte

LiPo batteries utilize a solid or gel-like polymer electrolyte instead of a liquid one. This allows for thinner and more flexible battery designs.

Cell Design

LiPo batteries are commonly found in pouch formats, making them lighter and more flexible compared to the rigid casing of Li-ion batteries. This design flexibility enables the creation of various shapes and sizes.

Advantages Weight and Flexibility: LiPo batteries are lighter and can be manufactured in customizable shapes, making them ideal for weight-sensitive applications. Safety: The polymer electrolyte minimizes the risk of leakage compared to liquid electrolytes, enhancing safety. Thin Design: LiPo batteries can be produced very thin, perfect for portable devices like smartphones and drones.

Summary of Key Differences Energy Density: Li-ion batteries generally have a higher energy density than LiPo batteries. Form Factor: Li-ion batteries are rigid and heavier, while LiPo batteries are lighter, flexible, and customizable. Cost: Li-ion batteries are usually more expensive due to their construction complexity, while LiPo batteries can also be costly due to their intricate manufacturing processes. Safety: Both battery types are safe when used correctly, but LiPo batteries can be more prone to swelling if overcharged or damaged.

Applications Li-ion: Commonly used in laptops, electric vehicles, and power tools due to their high energy density and longevity. LiPo: Preferred in applications like drones, RC cars, smartphones, and other portable electronics where weight and form factor are critical.

In summary, while Li-ion batteries are favored for their energy density and robustness, LiPo batteries are often selected for applications where weight, size, and flexibility are paramount.

Do LiPo Batteries Need a BMS?

Lithium polymer batteries are typically used with a Battery Management System (BMS), which is essential for ensuring their safety and longevity. Here are key reasons why a BMS is necessary for LiPo batteries:

1. Voltage Management Individual Voltage Monitoring: A BMS controls the voltage of each cell, ensuring it stays within the safe range (usually between 3.0V and 4.2V) to prevent overcharging or over-discharging. Balance Charging: The BMS balances the voltage across cells during charging, prolonging battery life by avoiding overcharging or overdischarging of individual cells. 2. Temperature Protection Temperature Monitoring: The BMS monitors the battery’s temperature during operation, automatically stopping charging or discharging if temperatures exceed safe limits, thus preventing overheating. 3. Overcurrent Protection Current Control: A BMS prevents excessive current flow during charging and discharging, which can cause overheating and damage. It automatically cuts off the circuit when current exceeds a safe level. 4. Overcharge and Overdischarge Protection Overcharge Protection: The BMS prevents overcharging by monitoring voltage levels and ensuring that the battery does not exceed safe limits, mitigating risks of thermal runaway or explosion. Over-discharge Protection: Prevents the battery voltage from dropping too low, which can damage the battery and reduce its lifespan. 5. Short Circuit Protection Short-Circuit Detection: In the event of a short circuit, the BMS quickly detects the fault and cuts off the current, preventing dangerous situations. 6. Condition Monitoring Real-Time Monitoring: The BMS provides users with real-time data about battery status, including remaining charge, health, temperature, and voltage, allowing for informed usage decisions.
