Collaborating researchers at Dongguk and Kyungpook National universities in South Korea have achieved a breakthrough in lithium-ion battery technology by developing a novel hybrid anode material. New intelligent protective layer suppresses dendrites, tackling a key barrier to lithium-metal battery commercialization. (Representational image) Getty Images South Korean researchers have unveiled a new lithium-metal battery technology that could push electric vehicles closer. A collaborative team from POSTECH (Pohang University of Science and Technology) and the Korea Institute of Energy Research (KIER) has developed a new anode material that could dramatically improve the performance of lithium-ion and sodium-ion batteries.
Unlike conventional lithium-ion batteries that rely on liquid electrolytes, these new batteries use solid electrolytes, offering higher energy density, enhanced safety, and a longer lifespan.
And because of its low de−/lithiation potential and specific capacity of 372 mAh g −1 (theory), graphite-based anode material greatly improves the energy density of the battery. As early as 1976, researchers began to study the reversible intercalation behavior of lithium ions in graphite.
At the beginning of the 21st century, aiming at improving battery energy density and lifespan, new modified graphite materials such as silicon-graphite (Si/G) composites and graphene were explored but limited by cost and stability.
The theoretical specific capacity of graphite is 372 mAh·g -1 , and its energy density is higher than those of most embedded cathode materials.
Practical challenges and future directions in graphite anode summarized. Graphite has been a near-perfect and indisputable anode material in lithium-ion batteries, due to its high energy density, low embedded lithium potential, good stability, wide availability and cost-effectiveness.
Increasing lithium storage capacity. Inert graphite surface hinders doping deposition. Depositing doping elements uniformly on graphite surface. Initial charge capacity: 1702.9 mAh/g (100 mA/g). 708.7 mAh/g/100 cycles at 0.1C. Enhancing conductivity and energy density. Breakage-prone graphite structure affects stability.
Conclusive summary and perspective Graphite is and will remain to be an essential component of commercial lithium-ion batteries in the near- to mid-term future – either as sole anode active material or in combination with high-capacity compounds such as understoichiometric silicon oxide, silicon–metal alloys, or elemental silicon.

The place to start this discussion is with the basic principles of charging a lithium-ion battery. When you plug our USB rechargeable batteries, electricity flows into the positive end of each battery. That pushes ions inside the battery to the negative end.

Battery drop test is a crucial examination method to assess the durability and safety of batteries. In this test, batteries are subjected to simulated drops to mimic real-world scenarios.
Battery drop test is a crucial examination method to assess the durability and safety of batteries. In this test, batteries are subjected to simulated drops to mimic real-world scenarios. Understanding battery drop testing procedures, types, standards, and regulations is essential for ensuring product quality and compliance.
Common misconceptions surrounding drop tests on car batteries can lead to misunderstandings about their effectiveness and importance. Drop tests solely measure internal resistance. All drop tests are performed the same way. A drop test eliminates the need for regular voltage checks. Drop tests accurately simulate real-world conditions.
Drop testing applies to all kinds of batteries, including lithium-ion, nickel-metal hydride, and alkaline batteries. Each type may have specific testing protocols depending on its use and regulatory requirements. How often should battery drop tests be conducted?
Yes, drop testing can cause permanent damage to a battery. This is why it's critical to test multiple samples and ensure that any failure does not pose a safety risk to users. Are there automated systems for battery drop testing? Automated drop test systems can precisely control the drop height, angle, and impact surface.
When performing a battery drop test, make sure that the battery is dropped from the specified height to accurately assess its bounce behavior. The bounce of a battery during the test is influenced by various factors, including the alignment of molecules inside the battery.
Evaluation of Safety: By subjecting batteries to drop impacts, manufacturers can assess the risk of leakage, thermal runaway, or explosion, ensuring that batteries meet safety standards and regulatory requirements.

This system is among the most important technology that can store energy through the flowing a current in a superconducting coil without resistive losses. The energy is then stored in act direct current (DC) electricity form which is a source of a DC magnetic field.
The first step is to design a system so that the volume density of stored energy is maximum. A configuration for which the magnetic field inside the system is at all points as close as possible to its maximum value is then required. This value will be determined by the currents circulating in the superconducting materials.
