1. Description:
In modern times, with the increased focus on renewable energy and reducing carbon footprints, electric cars have come to the spotlight. Tesla, Nissan, and Chevrolet are top companies in this new emerging trend. These three companies sell 60% of all-electric vehicles in USA and this figure is expected to increase as climate change and global warming became a major focus. Another biggest advantage of cars running on the electric battery is that they’re low maintenance, thereby ensuring increased efficiency and performance..
2. Feature Advantages:
1) High elasticity modulus
2) High stability
3) Good advanced ceramic materials
4) Low thermal conductivity
5) Chemical inertness
6) High temperature resistance
7) Stiffness texture
