How External Compressive Stress Influences Battery Performance? 2026

March 3, 2026

How External Compressive Stress Influences Battery Performance? Lithium-ion batteries represent the cornerstone of modern energy storage technology, and optimizing their performance remains a primary focus of current research. In practical applications, battery cells are frequently subjected to mechanical stress arising from module packaging constraints and volumetric changes induced by internal ionic diffusion. How this external compressive stress influences electrochemical behavior—specifically the underlying mechanisms in cathode materials like Lithium Iron Phosphate (LiFePO4)—remains a subject of ongoing investigation. While LiFePO4 is widely utilized for its high safety profile and long cycle life, its charge-discharge process involves a two-phase transition that results in a flat voltage plateau, posing significant challenges for state-of-charge (SoC)

What is Bipolar Stacking in Solid-State Batteries (SSB)? Source: WeChat Official Account “Battery Classroom”   Bipolar Stacking is widely regarded as the “secret weapon” for Solid-State Batteries (SSB) to unlock superior energy densities and high-voltage performance. While conventional liquid lithium-ion batteries are limited by monopolar cell architectures, solid-state technology enables a highly efficient bipolar design, fundamentally transforming how power is integrated within the cell. Bipolar stacking in solid-state batteries represents an innovative architecture designed to elevate system voltage and energy density by stacking multiple electrochemical cells in series. This approach simultaneously minimizes the use of inactive materials and streamlines the overall packaging design. By utilizing a shared current collector—which functions

The 4 Essential Battery Tab Welding Technologies: A Comprehensive Guide

February 28, 2026

The 4 Essential Battery Tab Welding Technologies: A Comprehensive Guide Source: WeChat Official Account “Battery Class” Battery tab welding is a critical process in ensuring the reliable operation of lithium-ion cells. Any negligence during this stage can lead to degraded performance, reduced range, compromised mechanical strength, and poor thermal efficiency—potentially escalating into significant safety hazards. To achieve robust tab-to-terminal connections (including foil-to-tab and tab-to-busbar), manufacturers must select the appropriate welding methodology. The choice depends on specific requirements such as material composition (e.g., Copper to Aluminum) and tab thickness. 1. Ultrasonic Metal Welding (UMW) Ultrasonic welding is the industry standard for foil-to-tab joining. It uses high-frequency ultrasonic vibrations to create a

Electric vehicles are already at 800V—is there really a need to push them all the way to 1200V?

Electric vehicles are already at 800V—is there really a need to push them all the way to 1200V? Source: WeChat Official Account “Frey Liu” Is 1200V the Next Frontier or Just Marketing Overkill? The Core Debate: Why the 800V “Sweet Spot” is Enough The EV industry is currently locked in a high-voltage arms race. While we’ve shifted from 400V to 800V/900V, some are already pushing for 1200V platforms. My Take: The performance dividends from the 800V transition are far from exhausted. Rushing to 1200V before solving existing cost and infrastructure hurdles is more about “tech-flexing” than improving the user experience. It will inevitably drive up costs with diminishing returns. 1.

Hot Take: A Sharp Critique of Donut Lab’s First Solid-State Battery Test Report 2026

Hot Take: A Sharp Critique of Donut lab’s First Solid-State Battery Test Report Source: WeChat Official Account “FreiLiu” 弗雷刘 Not long ago, the Finnish solid-state battery company Donut Lab made waves with a major announcement. They unveiled a battery cell technology boasting some truly staggering specs: Energy Density: 400 Wh/kg Charging Speed: Full charge in just 5 minutes Discharge Profile: Encourages full charge/discharge cycles Design Life: 100,000 cycles Operating Temperature: -30°C to 100°C Furthermore, the production process avoids rare materials entirely, utilizing “ubiquitous” eco-friendly materials that are free from geopolitical constraints. Perhaps most impressively, the production cost is reportedly lower than that of lithium-ion batteries with the same specifications. Today,
