Chongqing Feilong Jiangli collects the latest information for you, so that you can get the most cutting-edge technical information. A private company focused on developing the first rechargeable lithium-metal batteries in the United States announced that it would cooperate with SKI, Korea's largest energy and chemical company, to develop lithium-metal batteries.

This cooperation will focus on solid-state lithium anode laminates, which can double the energy density and cycle life of rechargeable batteries. The initial goal was to produce and test prototype batteries to prove whether the increase in volume and weight led to an increase in energy density and cycle life relative to existing lithium-ion batteries.

SK Innovation plans to complete the research on conductive glass separators by the end of 2021 and apply them to the development of lithium metal batteries. Conductive glass separator is the key technology to promote the stability of lithium metal batteries. The company hopes to successfully develop conductive glass separators to accelerate the commercialization of lithium-metal batteries.

A battery company based in Berkeley, California, USA, has invented and patented a technology to protect the electrodes of lithium-metal batteries, which is the core technology of sulfur-lithium batteries, lithium-air batteries and water-lithium batteries. Scientists at the battery company have invented a patented process that combines lithium metal with a continuous monolithic glass electrolyte. Battery validation in the laboratory indicates that continuous monolithic glass prevents dendrites and promotes lithium metal recycling.

      UniClutch Launches Clutch System in the United States
      By Counterman
      Australian clutch manufacturer Clutch Industries is launching two versions of its UniClutch system in the United States.
      UniClutch and UniClutch Sport will be the first iterations of the system to launch in the United States.
      UniClutch’s dual-core technology significantly boosts torque capacity without compromising drivability, according to the company.
      “Its one-of-a-kind, patented and adaptable design fits a multitude of vehicles, simplifies inventory management, expedites clutch replacement time, and lessens common installation problems,” Clutch Industries said in a news release.
      Compared to UniClutch, UniClutch Sport offers 15% more torque capacity and a sport-tuned pedal feel for more serious enthusiasts, the company noted.
      “We’re thrilled to introduce UniClutch to the United States after seeing strong early success in the Australia market,” said Brad Davis, CEO of Clutch Industries. “Auto repair shop feedback has been very positive, especially from technicians praising a faster and easier installation process. It’s also been our experience that shops can carry 20 times less inventory without impacting their ability to service any vehicle. We feel confident that UniClutch has the potential to redefine the performance clutch market with this revolutionary design.”
      Clutch installation typically is an expensive, complicated and lengthy process. UniClutch’s sealed design eliminates the need for flywheel machining, while the Flex Fit technology and pre-alignment allows for hassle-free “bolt-on” installation in minutes. The patented modular technology adapts to different engines and transmissions, greatly reducing installation times and empowering technicians to quickly service a wider range of vehicles.
      “For parts distributors, UniClutch’s patented Flex Fit technology will be transformative in inventory management, simplifying thousands of product variations to just a few,” Clutch Industries said. “This creates a solution for the complex ordering process for distributors, avoiding the challenges faced by an ever-changing supply chain. With UniClutch, parts distributors can provide consistent service to customers with a better return on investment.”
      A unique QR code found on every UniClutch contains manufacturing and performance specifications for each unit.
      At launch, UniClutch will retail exclusively at select NAPA Auto Parts stores across the United States and is available for purchase online via

      Assault on Batteries
      By Counterman
      This winter, extreme weather patterns have been disrupting daily routines nationwide. Flooding, snowfall and subzero temperatures all have taken a toll on our roadways and vehicles, leaving many stranded or unable to leave their homes. For those who can make it out to the streets, driving conditions can be hazardous. Having a reliable, fully charged battery is critical during these weather events.
      Several news reports lately have highlighted the negative effects of extreme weather on the growing segment of electric vehicles (EVs). Just as the lead-acid batteries found in conventional automobiles suffer during cold snaps, the battery packs found in EV and hybrid vehicles endure a similar kind of stress. As temperatures drop to freezing and below, EV efficiency (measured in miles per kilowatt-hour, or m/kWh) can be reduced by as much as 34%, shortening effective range. Unfortunately for EV owners, the reduction in range brought about by these cold temperatures means more frequent charging events.
      As temperatures plunge, these charging events can take even longer. EV batteries need to achieve a minimum internal temperature before accepting a charge, so the vehicle prioritizes battery preheating before it begins the actual charging process, which itself is less efficient at low temperatures. These delays can lead to lines at public charging stations, and increased numbers of immobile EVs stranded roadside when batteries go flat before reaching a charging station.
      Our customers with EVs still have the same type of 12-volt auxiliary battery commonly found in ICE-powered vehicles featuring stop-start technology. The BCI groups 400 and LN1 are just two of the popular AGM applications in this category. For ESS or hybrid vehicles, this battery is necessary for powering accessories when the engine is off, while EVs need a 12-volt power source isolated from their high-voltage traction systems. Maintenance-free AGM batteries are most often used in these applications, due to their ability to recharge quickly and a longer service life when compared to other types of lead-acid batteries.
      Lithium-ion batteries (like those used in cordless tools around the shop) are becoming a popular auxiliary option for EVs as well as ICE-powered vehicles. Lithium-ion batteries have a higher energy density than their lead-acid counterparts, so they can pack the same amount of power into a smaller (and lighter) case. Tesla has been using lithium-ion technology for its auxiliary battery in the Model 3, S, X and Y since 2021.
      Intelligent Battery Sensors
      As batteries and charging systems become more advanced, use of an intelligent battery sensor (IBS) is becoming more commonplace. BMW has used battery sensors since 2002, and uniquely requires “registration” to notify the PCM that a new battery has been installed. This update allows the PCM to tailor the battery-management system to the output of the new battery. The sensor now has a reset “baseline” to make decisions on charging voltage, idle speed and other parameters that affect drivability and battery life. In addition to measuring current in and out of the battery, the IBS also may monitor battery state of charge, state of health and even temperature.
      No matter if you’re daily-driving an ICE or an EV, a properly maintained battery and charging system is critical to reliable starting in all kinds of weather. Fortunately, given today’s battery technologies, it’s even easier to maintain and monitor these systems than ever before!

      Advance Giving Away Free Batteries to Randomly Selected Customers on National Battery Day
      By Counterman
      new national survey by Atomik Research reveals 91% of American motorists say they’ve experienced a dead battery, but nearly two-thirds (65%) of motorists admit they don’t think about having their car battery checked until it’s too late.  
      To raise awareness of the importance of having a reliable car battery, Advance Auto Parts is giving away free DieHard batteries on National Battery Day, which is Sunday, Feb. 18. 
      Advance said it will surprise randomly selected customers with a free DieHard battery, including those getting their current battery tested, at participating stores nationwide.
      As part of National Battery Day, Advance is partnering with Tampa Bay Buccaneers quarterback Baker Mayfield to encourage motorists to get their car batteries tested.  
      “Checking the performance of your car battery can prevent unfortunate and even unsafe events caused by dead batteries,” said Junior Word, Advance’s executive vice president, U.S. stores. 
      Additional data from the national Atomik survey commissioned by Advance in January underscores the need to remind motorists to get their car batteries checked:    
      Sixty-five percent of motorists say they’ve missed or been late to something due to a dead car battery; nearly 10% say they missed or were late to an important life event – such as a wedding, funeral or birth of a child.  Only 2% of motorists indicate they’ve had their car battery checked before a cross-country road trip.  Only 5% of motorists report having ever checked their car battery when there is a drop in temperature.  The post
