  • Energy Storage Systems Boost Battery Safety Significantly

    Energy Storage Systems Boost Battery Safety Significantly

    Key Takeaways

    1. Most failures in energy storage systems (ESS) are due to auxiliary systems, not battery defects, with battery cells accounting for only 15% of defects.
    2. Battery safety ratings have improved significantly, with a doubling of safety ratings in the past year.
    3. By 2024, 72% of failures will stem from secondary systems rather than battery cells, indicating a shift in failure sources.
    4. Safer battery chemistries, like sodium-ion and lithium iron phosphate, are contributing to improved safety in ESS.
    5. Mandatory large-scale fire tests for ESS will be implemented by 2026 to enhance safety standards in North America.


    As energy storage systems (ESS) increase in capacity to levels that can supply energy to a home for more than five years, the safety record of these batteries is also improving.

    Battery Defects Decline

    A recent study reveals that most failures in ESS are not caused by defects in the batteries themselves but rather by problems in their auxiliary systems. Currently, battery cells and modules account for only about 15% of all defects in energy storage systems, showing a significant decline in failure rates.

    Research from Clean Energy Associates (CEA), which included random testing of over 65 GWh in energy storage projects, found that battery safety ratings have doubled in the past year. In 2023, battery cells were responsible for 30% of ESS failures, while auxiliary systems, including fire suppression and thermal management systems, made up 48% of all defects.

    Shift in Failure Sources

    By 2024, the situation had shifted dramatically, with 72% of manufacturing, installation, or operational failures arising from secondary systems of the ESS rather than the battery cells themselves.

    This change may be attributed to the rise of safer battery chemistries, like sodium-ion and lithium iron phosphate (LFP), which are commonly found in popular portable power stations such as the Anker Solix C1000.

    Additionally, the implementation of new safety standards and certification tests has also played a role in ensuring that batteries in energy storage systems are no longer the primary safety concern.

    Future Safety Standards

    Looking ahead to 2026, the ESS industry in North America will face mandatory large-scale fire tests designed to simulate thermal runaway scenarios. According to the CEA, “Product certification, third-party quality assurance, and direct communication with communities are essential to build trust.”

  • Anker Recalls Power Bank Model Over Fire Risk Concerns

    Anker Recalls Power Bank Model Over Fire Risk Concerns

    Anker, a prominent brand in mobile accessories, has announced a recall of a particular model of its portable power bank due to a possible fire risk. The product in question is the Anker 321 Portable Power Bank (PowerCore 5K, Model A1112), with units manufactured after March 2023 being affected.

    Anker Issues Urgent Recall for Portable Power Banks

    Anker has identified a manufacturing flaw that may cause the lithium-ion battery in these power banks to overheat. This overheating can lead to the melting of the device’s plastic parts, release of smoke, or even a fire hazard.

    While Anker emphasizes that only a small batch of power banks made after March are implicated, the company is proactively recalling all units of this model.

    If you possess an Anker 321 Power Bank, it’s essential to check if it is part of the recall. Look for the white label on the bottom of the device, which should read “Anker 321 Power Bank (PowerCore 5K, Black), Model: A1112.” If your unit matches this description, Anker advises you to stop using the power bank immediately.

    Recall Verification and Replacement Process

    Anker has created a special webpage to manage the recall process. Consumers can visit the page to check their power bank’s serial number and confirm if it is included in the recall. If verified, Anker is offering a complimentary replacement with the Anker 533 Portable Power Bank. To speed up the replacement process, Anker suggests having proof of purchase ready when completing the online form.

    Anker also highlights the importance of proper battery disposal. Discarding them in regular trash cans or recycling bins can be dangerous to the environment and pose fire risks. Anker’s website offers guidance on responsible battery disposal methods specific to various regions.

    Consumer Safety Tips

    This event underscores the importance of caution when using portable power banks. Always buy these devices from reputable brands and authorized sellers. Look for certifications from recognized organizations that ensure safety standards are upheld. Regularly check your power bank for any damage and avoid using any device that appears to be faulty.
