Bipolar Plates for hydrogen fuel cell vehicles (FCEV). Traditional graphite bipolar plates are brittle and large in volume. Titanium alloys (such as Ti-6Al-4V or pure titanium with platinum coating) have become ideal alternative materials due to their high corrosion resistance, electrical conductivity and strength. The second-generation model adopts ultra-thin titanium alloy bipolar plates, reducing the battery stack volume by 30% and having a lifespan of over 15 years. Titanium alloy for hydrogen storage systems is used as the inner lining of high-pressure hydrogen storage tanks (such as Ti-CFRP composite materials), featuring both lightweight and hydrogen embrittlement resistance, with a weight reduction of over 40% compared to traditional steel tanks.
Titanium alloys (such as Ti-3Al-2.5V) for the structural components of battery packs in pure electric vehicles (BEVs) are used in battery casings or brackets to reduce weight and enhance collision safety. The load-bearing structure of part of the battery pack is made of titanium alloy to meet the high-strength requirements. The titanium alloy honeycomb structure battery casing improves heat dissipation efficiency by 20%. The fast charging system uses high thermal conductivity titanium alloy (such as modified titanium alloy with added copper or graphene) for the charging interface heat dissipation module, supporting 800V high-voltage fast charging.
Lightweight body and chassis are applied to high-end models. Some suspension connecting rods are made of titanium alloy, reducing weight by 15% while enhancing rigidity. Titanium alloy fasteners and suspension components have reduced the vehicle's weight by up to 30 kilograms. Cost optimization technology: Laser additive manufacturing (3D printing) of titanium alloy complex structural parts to reduce material waste. Titanium-aluminum composite technologies (such as Ti-Al laminates) reduce material costs.
