A team in Penn State’s Battery and Energy Storage Technology (BEST) Center have developed a safe, high power lithium-ion battery capable of providing 1 million miles for electric vehicles. This is equivalent to over 4000 cycles or approximately 2x the cycle life of lithium iron phosphate batteries.
The team took a totally different approach to build this battery. They broke it down to two parts, the first was to build a battery with highly stable materials. The second step was to introduce heating into the battery. Chao-Yang Wang, professor of mechanical, chemical and materials science and engineering developed a self-heating battery to overcome performance problems in cold climates. The battery can heat up in seconds by using electric current. This heating also gives the battery an instant boost in reactivity because of the law of kinetics.
Together these two steps create a battery that is both highly safe and able to provide high power that an electric vehicle requires.
The next project for the team will be developing a solid-state battery.
