Researchers develop sodium battery capable of rapid charging in just a few seconds

Future Batteries（Article illustrations）

Sodium (Na), which is over 500 times more abundant than lithium (Li), has recently garnered significant attention for its potential in sodium-ion battery technologies. However, existing sodium battery face fundamental limitations, including lower power output, constrained storage properties, and longer charging times, necessitating the development of next-generation energy storage materials.

A research team led by Professor Jeung Ku Kang from the Department of Materials Science and Engineering has developed a high-energy, high-power hybrid sodium-ion battery capable of rapid charging.
This research, co-authored by KAIST doctoral candidates Jong Hui Choi and Dong Won Kim, was published in the journal Energy Storage Materials with the title “Low-crystallinity conductive multivalence iron sulfide-embedded S-doped anode and high-surface-area O-doped cathode of 3D porous N-rich graphitic carbon frameworks for high-performance sodium-ion hybrid energy storages.”
The innovative hybrid energy storage system integrates anode materials typically used in batteries with cathodes suitable for supercapacitors. This combination allows the device to achieve both high storage capacities and rapid charge-discharge rates, positioning it as a viable next-generation alternative to lithium batteries.
However, the development of a hybrid battery with high energy and high power density requires an improvement to the slow energy storage rate of battery-type anodes as well as the enhancement of the relatively low capacity of supercapacitor-type cathode materials.

portable device decorate img

To account for this, Professor Kang’s team utilized two distinct metal-organic frameworks for the optimized synthesis of hybrid batteries. This approach led to the development of an anode material with improved kinetics through the inclusion of fine active materials in porous carbon derived from metal-organic frameworks.

Additionally, a high-capacity cathode material was synthesized, and the combination of the cathode and anode materials allowed for the development of a sodium-ion storage system optimizing the balance and minimizing the disparities in energy storage rates between the electrodes.

The assembled full cell, comprising the newly developed anode and cathode, forms a high-performance hybrid sodium-ion energy storage device. This device surpasses the energy density of commercial lithium-ion batteries and exhibits the characteristics of supercapacitors’ power density. It is expected to be suitable for rapid charging applications ranging from electric vehicles to smart electronic devices and aerospace technologies.

Professor Kang noted that the hybrid sodium-ion energy storage device, capable of rapid charging and achieving an energy density of 247 Wh/kg and a power density of 34,748 W/kg, represents a breakthrough in overcoming the current limitations of energy storage systems. He anticipates broader applications across various electronic devices, including electric vehicles.

Tools Needed

Multimeter: A digital multimeter with the capability to measure DC voltage is preferred for its accuracy and ease of use.

Safety Gear: Gloves and protective eyewear to ensure safety from battery acid and electrical sparks.

Preparing for the Test

Safety First: Ensure the area is well-ventilated. Batteries can emit hazardous gases.

Check Multimeter Setting: Set your multimeter to the DC voltage scale. This setting is usually denoted by a ‘V’ with a straight line.

Inspect Battery and Clean Terminals: Check the battery for any signs of damage or leakage. Clean the terminals using a wire brush to remove any corrosion, ensuring reliable test results.

Step-by-Step Guide to Testing Your Battery

Connect the Multimeter:

Secure the multimeter’s red probe to the battery’s positive terminal and the black probe to the negative terminal.

Make sure connections are firm to avoid fluctuating readings.

Reading the Voltage:

A stable reading should appear on the multimeter. For a 12-volt battery, a reading between 12.6 to 12.8 volts indicates a fully charged state.

Record the voltage when the battery is both at rest and under load to understand how it performs during actual usage.

Interpreting the Results:

12.6 volts or higher: Indicates the battery is healthy and fully charged.

12.0 to 12.5 volts: Shows a battery in a fair state but possibly in need of charging.

Below 12.0 volts: Suggests a discharged or failing battery that requires further testing or replacement.

Advanced Testing: Load Testing

For a more comprehensive analysis, performing a load test can be crucial:

What is Load Testing?: This test simulates the battery’s performance under typical operating conditions.

Procedure: Apply a specific load to the battery and measure voltage response. A significant drop in voltage could indicate a weak battery.

Maintenance Tips Post-Testing

What Should a 12 Volt Battery Read When Fully Charged?

12V lifepo4 battery pack

In the world of batteries, understanding the state of charge is critical for maintaining their longevity and efficiency. A 12-volt battery, commonly used in cars, boats, and solar panel systems, is a staple in various applications. Knowing what voltage it should read when fully charged not only helps in maximizing its utility but also ensures the safety and operational reliability of the device it powers.

Introduction to 12 Volt Batteries

A 12-volt battery is often referred to as a lithium battery, which is one of the most prevalent types used in automotive and solar applications.

Despite the name, a s rd 12-volt battery will typically provide a slightly higher voltage when fully charged.

This characteristic is crucial for the proper functioning of the battery and the equipment it operates.

Understanding Voltage and Charge Levels

Voltage in a battery is like a snapshot of its health and charge level. For a 12-volt LiFePO4 battery, the fully charged voltage and the state of discharge go hand in hand:

12.8 volts and above: At rest (no load condition and no recent charging), a reading of 14.2 volts or more usually indicates a fully charged battery.

13.3 volts: Represents about 75% charge and is sufficient for most operational needs.

13.2 volts: Shows about 50% charge, a critical midpoint where you might want to consider recharging to avoid deep discharge states.

 

Charging to Full Capacity

Ensuring that a 12-volt battery reaches its optimal charge level involves not only using the right charger but also understanding the charging process:

 

Stage1: Bulk Charge – This stage brings the battery up to approximately 80% of its full capacity by applying a high charge rate. Voltage gradually increases while closely monitoring the temperature to prevent overheating.

Stage 2: Absorption Charge – The charger reduces the current and allows the voltage to reach its peak at around 14.4 to 14.8 volts for a typical lead-acid battery. This stage completes the charging up to near 100%.

Stage 3: Float Charge – Finally, the charger lowers the voltage and provides a small current to keep the battery at 100% charge without overcharging it. The voltage in this stage should be about 13.6 to 13.8 volts.

Maintaining Your Battery

Proper maintenance of a 12-volt battery is essential for extending its life and ensuring it consistently performs well:

Regular Checking: Frequent voltage checks with a reliable multimeter can prevent overcharging or deep discharge, which are detrimental to battery health.

Clean Connections: Ensure that the battery terminals are clean and corrosion-free to provide good electrical connectivity.

Proper Storage: When not in use, store the battery in a cool, dry place and periodically charge it to keep it from entering a deep discharge state.

Conclusion

Knowing what a fully charged 12-volt battery should read is vital for anyone relying on battery-powered equipment. With proper understanding and maintenance, you can ensure that your 12-volt batteries serve you well for years to come.

Whether you’re a boating enthusiast, a car owner, or manage a bank of solar batteries, keeping the battery fully charged and well-maintained is your key to uninterrupted power supply and operational efficiency.
