Harvard Scientists Reveal Battery Breakthrough

Scientists at Harvard have just made a breakthrough for the EV industry by creating an optimized, high-capacity, energy-dense battery that promises stable enhancement to electric vehicles worldwide.

To put it bluntly, it’s hard to be energy efficient when fuel-driven engines have been top of the list for distance and price per mile. And it’s been extremely difficult to create a lithium-metal (not to be confused with lithium-ion) battery that will maintain stability and longevity without tiny cracks of lithium dendrite appearing within the energy cells of the design – until now.

The report from Harvard states that this new ‘holy grail’ lithium-metal battery can do it all.

Here’s What We Know So Far

It can charge in a fraction of the typical estimated time.

It can hold up to 10,000 charges.

And as if that weren’t enough, it will be able to house a huge amount of energy compared to the current competition on the market.

According to Visordown, this is done by the clever use of less stable electrolytes, sandwiched between more solid-based, stable electrolytes in a multi-layer, Big Mac design to prevent cracks from dismantling the system.

This helpful (and drool-worthy) diagram was provided by an article on Harvard regarding the anatomy and construction of the Lithium-metal batteries currently being tested. Yum.

Xin Li, an associate professor of Harvard, says the following:

“A lithium-metal battery is considered the holy grail for battery chemistry because of its high capacity and energy density…but the stability of these [lithium-metal] batteries has always been poor… By studying their fundamental thermodynamics, we can unlock superior performance and harness their abundant opportunities.”

“This proof-of-concept design”, he adds, “shows that lithium-metal solid-state batteries could be competitive with commercial lithium-ion batteries. And the flexibility and versatility of our multilayer design makes it potentially compatible with mass production procedures in the battery industry. Scaling …read more
