Thermal runaway reaction – can it be prevented?

Thermal runaway reaction – can it be prevented?

As more industries and applications turn to battery technology in order to create sustainable energy solutions, ongoing research and development into making them safer is vital. 

A significant risk to safety which is present particularly in high energy density batteries is thermal runaway. Thermal runaway can cause an unstoppable reaction that leads to incredibly high temperatures and fire which can be difficult if not impossible to extinguish by conventional methods.

So, the ongoing challenge and question is – can thermal runaway be prevented?

Compression pads for batteries – why are they useful?

Compression pads for batteries – why are they useful?

As the electric vehicle (EV) market gains momentum, and we creep ever closer to the 2030 deadline for an end to the sale of fossil fuel vehicles in the UK, innovation in the field of EV batteries is happening at a rapid pace. 

Even closer deadlines include 2025 for Norway, meaning manufacturers must work to increase the storage capacity and life cycle of battery packs whilst balancing performance, cost and safety. 

In this article, we’re going to examine why compression pads for electric vehicle batteries are useful in ensuring optimal performance, extending the life of the battery pack and increasing the safety of the vehicle occupants. 

How will COVID affect the electric vehicle market?

How will COVID affect the electric vehicle market?

As part of the global initiative to combat climate change, the sale of non-electric vehicles will be banned in 9 countries by 2030. In the UK, where the date is currently 2035, there has been talk of bringing this forward to 2030. Some countries have plans for earlier bans – such as Norway, which plans to phase them out by 2025, and Austria, who planned to stop the sale of them this year. These initiatives and benchmarks have proven to be the impetus behind legislation, innovation and movement in the electric vehicle market over the last couple of years.

Addressing electric vehicle safety concerns

Addressing electric vehicle safety concerns

The probability of an electric vehicle (EV) catching fire is significantly lower than that of an internal combustion engine (ICE) vehicle. According to the Fatality Analysis Reporting System, between 1993 and 2013 in the US, fires occurred in 2.6% of EVs, and in 4.4% of ICE vehicles. However, over the last few years as EVs have become more prominent, there have been well-publicised issues with fire occurring in electric vehicles – with Tesla being the worst hit. Risk is abundant in any motor vehicle – but it’s essential to understand the unique risks involved with manufacturing and operating EVs, and how they can be mitigated. Here are some electric vehicle safety concerns around battery damage and fire risk and how they can be addressed.

3 ways mica can be adapted and used for various applications

3 ways mica can be adapted and used for various applications

Mica is an incredibly versatile and flexible material. Due to its unique physical, electrical and thermal properties, it makes an ideal insulation material. Across the broad requirements of industry, there are billions of machines, components and products that need to be insulated – all requiring a slightly different approach, and slightly different material. Because mica is so versatile, it can be adapted into various applications through cutting, shaping and combining with other substances to create unique insulation solutions.

Here are 3 ways in which mica is commonly adapted for use in various applications.

What is thermal runaway and how can it be addressed?

What is thermal runaway and how can it be addressed?

Thermal runaway is a significant risk present in batteries. It occurs due to a battery cell failure of some kind, occasionally as simple as the separator between the anode and the electrolyte breaking down. This generates an increase in temperature, creating a chain reaction in which more energy is released, causing the electrolyte to break down into flammable gasses. Once the separator melts, the cathode of the battery breaks down further fuelling the fire with oxygen, triggering an uncontrolled positive feedback loop, often leading to a destructive result. The risk of thermal runaway begins at 60°C and becomes extremely critical at 100°C. Once the process has begun, temperatures rise rapidly within milliseconds – creating temperatures of around 400°C. It is particularly prevalent in lithium-ion batteries.
