    Farasis Energy Unveils Fast-Charging Battery Tech for EVs

    Key Takeaways

    1. Farasis Energy has developed a technology that allows EV batteries to charge from 10 to 80 percent in just 8.55 minutes.
    2. The company achieved 6C ultra-fast charging, enabling batteries to absorb power six times faster than they discharge.
    3. The technology improves battery design for 6C lithium iron phosphate (LFP) and 5C lithium ternary battery systems.
    4. Enhanced heat management features increase heat dissipation areas by 4.8 times for LFP and 4.0 times for ternary batteries, keeping temperatures below 50°C during rapid charging.
    5. Farasis Energy currently holds a 0.48 percent share of the Chinese battery market.

    For a lot of people, one of the biggest hassles with owning an electric vehicle (EV) is how long it takes to charge. Unlike quickly filling up a gas tank in a traditional car, putting energy into an EV battery is a time-consuming process, especially on long road trips. However, Farasis Energy has introduced a new technology that enables batteries to charge from 10 to 80 percent in only 8.55 minutes.

    Fast Charging Breakthrough

    The Chinese firm asserts that it has reached 6C ultra-fast charging, which means its batteries can absorb power six times quicker than they discharge it. Jian Weiran, the VP of research and development at Farasis Energy, explained that their technology enhances the battery design for 6C lithium iron phosphate (LFP) and 5C lithium ternary battery systems.

    Enhanced Heat Management

    This innovative battery’s super pouch solution (SPS) improves the heat dissipation areas on the 6C LFP and 5C ternary batteries by 4.8 and 4.0 times, respectively. This enhancement allows the batteries to maintain temperatures below 50°C during rapid charging. The better heat management could help electric vehicle manufacturers reduce charging times.

    Farasis Energy holds a mere 0.48 percent share of the Chinese battery market.

  • Great Wall Motors Unveils Solid-State Battery and Fast Charging

    Great Wall Motors Unveils Solid-State Battery and Fast Charging

    Great Wall Motors (GWM) has made a major advancement in its solid-state battery and ultra-fast charging technologies. The Chinese automotive company has successfully created solid-state pouch cells, marking the final stage in the development of solid-state batteries. The next step involves scaling this model for commercial production on a large scale.

    Solid-State Battery Advantages

    Solid-state batteries differ from the current lithium-ion batteries by using a solid material instead of a liquid electrolyte. This results in significantly higher energy densities and faster charging times compared to lithium batteries.

    Overheating poses a serious safety risk for electric vehicles (EVs), and solid-state batteries offer improved stability in this respect. They are less likely to overheat and catch fire, issues commonly associated with lithium-ion batteries. These batteries are expected to be more reliable across a wide temperature range, including cold weather conditions. GWM is also investigating various battery chemistries alongside its solid-state battery efforts.

    Ultra-Fast Charging Developments

    GWM is also making significant strides in accelerating charging speeds through its ultra-fast charging technology. The GWM 4C supercharging battery cell can add up to 311 miles (500 km) of range in just 10 minutes of charging. This innovation has significant positive implications for long-distance EV travel, virtually eliminating the time penalty.

    GWM is also working on a 6C cell that will further reduce charging times. It is anticipated that GWM's solid-state battery and ultra-fast charging products will be released soon. These technologies could debut on the Tank 800 SUV by the end of 2024. Additionally, the GWM Lightning Cat sedan will be updated later this year and may feature the latest GWM battery technology.

    Tackling the Dendrite Predicament

    One of the primary obstacles in solid-state battery progress pertains to the formation of dendrites on the anode. The innovative approach by the Harvard researchers involves a multilayer battery design that strategically positions various materials between the anode and cathode, effectively minimizing dendrite formation.

    Integration of Micron-Sized Silicon Particles as a Solution

    The pivotal advancement revolves around the incorporation of micron-sized silicon particles within the anode structure. This strategic deployment impedes dendrite proliferation while facilitating the envelopment of lithium metal around the silicon particles. Consequently, this technique enables swift plating and stripping processes, culminating in a complete recharge in approximately 10 minutes.

    Evaluation of Performance and Commercial Potential

    Upon undergoing 6,000 cycles, the developed battery cell managed to uphold 80% of its original capacity. The proprietary technology has been licensed to Adden Energy, a spinoff of Harvard’s research initiatives, which intends to expand the technology for integration into larger-scale smartphone batteries.

    Hurdles and Prospective Implementations

    While challenges loom over the mass production of solid-state batteries, this research marks a crucial milestone towards the realization of functional solid-state batteries with diverse industry applications.

    Wrapping Up

    The breakthrough achieved by the Harvard research team holds immense promise for the accelerated charging of batteries in the EV domain and beyond. By capitalizing on micron-sized silicon particles, the issue of dendrite formation has been effectively resolved, bringing the practical application of solid-state batteries within closer reach.
