“When Tesla boosted 21700 battery cycle life to 2,000 cycles with pulse charging, and a power tool brand recalled 120,000 sets of products due to uncontrolled constant voltage charging – charging algorithms are becoming the second lifeline for batteries. As an engineer involved in the development of the IEC 62133 standard, I will use blood…
Engineer’s Opening Strike “When the energy density of 400Wh/kg becomes the admission ticket of all-solid-state battery, high nickel positive electrode + sulfide electrolyte is becoming the ultimate track for the head enterprises to race for life and death. The yield rate of Ningde Times pilot line exceeded 92%, Vonergy delivered 60Ah battery cells at the…
Lithium iron phosphate (LFP) remains a staple in power batteries and energy storage due to its safety and long cycle life. However, battery manufacturers often face challenges: switching to a new batch of LFP material can cause fluctuations in slurry quality, electrode performance, and final battery properties—directly impacting production efficiency and causing significant economic losses….
Copper foil is used as the anode carrier and collector of lithium-ion batteries, and the thickness of copper foil plays a crucial role in lithium batteries, which affects the performance, safety and cost of lithium batteries. Next we come to a detailed analysis of the lithium battery copper foil thickness is specifically how to affect…
A piece of silver-white lithium metal, is becoming the core pivot to pry hundreds of billions of solid-state battery market. Linwu County, under the mines, a material revolution quietly opened. June 18, Dazhong Mining announced an investment of 1 billion yuan in Hunan Linwu County to build an annual output of 3,000 tons of lithium…
The core parameter of lithium battery slurry viscosity, detailing its influencing factors, the specific role of battery performance, control strategies, as well as research progress and future direction. Slurry viscosity throughout the lithium battery manufacturing multiple links, the final performance of the battery has a significant impact. By comprehensively analyzing the relevant content, we aim…
Core logic: solid state battery industrialization follows the path of “equipment first → material follow-up → scene landing”, and 2025-2027 is the key period for mass production verification. Equipment link is the first to benefit from the construction of production lines, solid-state battery equipment industry chain value release pioneer. I.the value of equipment reconstruction: technology…
Lithium-ion battery pole piece manufacturing is a key process in the battery production process, specifically including the preparation of slurry, pole piece coating and drying, pole piece roll compaction, and pole piece cutting. In the battery wafer preparation process, more and more online inspection technologies are adopted to effectively identify manufacturing defects, reject defective products,…
Engineers strike hard from the outset “When CATL said ‘interface impedance remains unsolved,’ Toyota pushed mass production back to 2030, but Xinwangda’s solid-state battery mass production date is set in stone for 2026! This isn’t just talk: 320Wh/kg batteries are already installed in drones, 360Wh/kg samples have passed military-grade needle penetration tests, and they’ve even…
In freezing weather, most batteries fail—phones die, electric cars stall, and outdoor equipment shuts down. That’s where low temperature batteries step in. These specialized power sources are rewriting the rules for energy storage in cold environments, solving problems traditional batteries can’t handle. Let’s break down why they matter, how they work, and where they’re making…
