INTRODUCTION
A substance called silicon foam has a three-dimensional network of linked pores that are filled with gas or air. Due to its high surface area to volume ratio, this kind of material is appealing for a variety of uses, including as a battery electrode material.
It has being investigated whether silicon foam could replace graphite as the anode material in electric vehicle (EV) batteries. As comparison to graphite, silicon has a higher theoretical capacity for lithium-ion storage, which implies it can hold more energy per unit of weight or volume.
The substantial volume changes that silicon experiences throughout the charging and discharging cycles, on the other hand, might cause cracking and pulverisation of the electrode material.
These problems can be lessened by using silicon foam as an anode material in lithium-ion batteries since it offers a more stable structure for the silicon particles to be lodged in. Since the silicon particles can expand and contract while being charged and discharged, less electrode damage is likely because of the foam’s porous structure.
Before silicon foam for EV batteries can be commercialised, research is still in its early phases and there are several obstacles to be overcome. They include creating scalable production techniques, enhancing the integration of the foam with other battery components, and enhancing the long-term cycle stability and longevity of the foam structure.
GLOBAL EV BATTERY SILICON FOAM MARKET SIZE AND FORECAST
Global EV battery silicon foam market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
NEW PRODUCT LAUNCH
On January, in San Diego, California, during the IPC APEX Expo, The CHT Group will unveil a brand-new silicone foam. SilSo Lite 21025 from CHT is a two-part, platinum-cure, self-blowing silicone foam that blows into a closed-cell structure at room temperature.
The SilSo Lite 21025 from CHT satisfies requirements for weight reduction, thermal runaway mitigation, moisture, debris, vibration, and shock protection for electronic components and EV battery packs. Where low smoke, flame, and toxicity are required, this silicone foam is also perfect.
The SilSo Lite 21025 is a liquid system with a 1:1 mix ratio and low viscosity that makes it simple to dispense using a cartridge or an automated mixing machine.
The quick gel time of this silicone foam will aid in boosting production throughput, and it offers primerless adherence to a range of surfaces. Moreover, utilising one of the primers suggested by CHT will increase adhesion. In roughly 10 minutes, SilSo Lite 21025 will grow 2–3 times its liquid volume and complete curing.
