RENEWCONNECT - All about renewables & power sector

As  battery technology rapidly grows with its energy density, technical failures are also taking place after the 100's and 1000's tests are made. Considering all the technical, environmental, commercial, and most importantly Safety issues, more advanced batteries are coming into the EV market that will be light, safe, viable, long-lived, with high energy density, etc. 1. Solid-State Batteries (SSBs) What are Solid-State Batteries? A next-generation battery technology that replaces the flammable liquid electrolyte in lithium-ion batteries with a solid electrolyte. Advantages for Safety: Reduced Fire Risk: Solid electrolytes are non-flammable, drastically lowering the risk of thermal runaway. Higher Thermal Stability: Operates efficiently across wider temperature ranges. Enhanced Durability: Less prone to degradation, reducing the risk of short circuits. Compact Design: Higher energy density allows for smaller battery packs with advanced safety layers. Challenges in Adoption: Hig...

Introduction Electric Vehicles (EVs) are rapidly transforming the global transportation landscape, offering environmental and economic benefits. However, battery safety challenges, particularly the risk of fires, have emerged as critical issues. This roundtable discussion explores the technical, regulatory, and market perspectives on EV battery safety. Key Issues Contributing to EV Battery Fires Thermal Runaway A chain reaction where excessive heat in a battery cell triggers a reaction in neighboring cells. Caused by overcharging, overheating, or internal short circuits. Battery Manufacturing Defects Poor quality control during cell production can lead to internal short circuits. Issues include improper electrode alignment or contamination. External Impacts Damage caused by collisions or punctures can compromise the integrity of the battery pack. Environmental Factors High ambient temperatures and humidity accelerate battery degradation. Improper Charging Practices Overcharging or usin...
