The progress of robots continues to break through, and the short-term technological growth mainline may continue to dominate: Starting from the auto show, the overall improvement of domestic demand and technological growth brought by new supply are still the two clear investment mainlines for the automotive sector. The improvement of domestic demand is currently dependent on technological iteration, customer expansion, and upward trend correction....

Robot inspired dexterous hands can achieve precise simulation of human hand movements; The dexterous hand is an output tool for humanoid robot operation and action decision execution. It imitates the bending and swinging movements of human fingers to achieve functions similar to human hands (such as grasping, gripping, holding, precision assembly, etc.). The human hand has up to 21 degrees of freedom in one hand. Looking at it separately:

On May 13th, a middle-level employee of a domestic lithium battery listed company told reporters that the reduction is definitely a positive news. The originally expected demand for batteries in the US market and the growth rate of the company's business in the US should be ensured, but the specific situation is still being evaluated internally.

In the manufacturing process of lithium batteries, the A/B misalignment problem, which is often overlooked in the coating process, actually has a significant impact on the capacity performance, safety performance, and cycle life of the battery. The so-called misalignment mainly refers to the inconsistent position or uneven thickness distribution of the coating on both sides of the pole piece, which can easily lead to potential risks such as local lithium deposition and mechanical damage to the pole piece....

Constructing a carbon based carrier with high porosity for accommodating silicon nanoparticles and buffering volume expansion; Raw material selection: Select biomass carbon, polymer carbon, or commercial hard carbon, with a porosity of>60% and uniform pore size distribution (mainly micropores mesopores).Process steps: Carbonization in an inert atmosphere (Ar/N ₂) at high temperature (800-1200 ℃) to form a porous structure; Activation through KOH or CO ₂ further enlarges the pores, increasing the specific surface area (>1000 m ²/g). Equipment continuous atmosphere rotary furnace (such as Longxin drying equipment), supporting inert gas protection and precise temperature control....

Root cause of the problem: During lithiation (charging) of silicon, each silicon atom can combine with up to 3.75 lithium ions (forming Li ₁₅ Si ₄), resulting in a volume expansion of approximately 300-400%. During lithium removal (discharge), it will shrink again. This repeated expansion contraction will generate mechanical stress.
