Lithium metal battery energy storage mechanism

What is a lithium based battery?

Lithium (Li)-based batteries, particularly Li-ion batteries, have dominated the market of portable energy storage devices for decades 1.

How to increase the energy density of lithium-ion batteries?

One of the viable options to increase the energy densities of lithium-ion batteries (LIBs), taking full advantage of the state-of-the-art LIB technology, is to adopt Li-metal anode in the cell, which affords the highest theoretical capacity (3860 mAh g −1) among the anode materials 1, 2.

How have lithium ion batteries impacted modern society?

Lithium (Li)-ion batteries have had a profound impact on modern society 1. Over the past 25 years, the specific energy of Li-ion batteries has steadily increased while their cost has dramatically decreased.

Are lithium-ion batteries reaching their energy limits?

Nature Energy 4, 180–186 (2019) Cite this article State-of-the-art lithium (Li)-ion batteries are approaching their specific energy limits yet are challenged by the ever-increasing demand of today’s energy storage and power applications, especially for electric vehicles.

What is a lithium metal battery (LMB)?

Lithium metal batteries (LMBs) has revived and attracted considerable attention due to its high volumetric (2046 mAh cm−3), gravimetric specific capacity (3862 mAh g−1) and the lowest reduction potential (−3.04 V vs.SHE.).
