Why are lithium-ion batteries important?

 The world is shifting away from fossil fuels and will one day become fully electric.

 Every time the world has harnessed a new generation of energy, be it fire, steam, or diesel, there have been fundamental and broad-stretching  improvements to our lives.

 Electrical energy stored in batteries will have great implications to the world in the next twenty years as technologies like electric vehicles,  smart homes, robotics, and solar power collection are able to reach their full energy potentials.

 Lithium-ion is the most promising chemistry of all batteries. Li-ion manufacturers have a regular cycle of improvements, and goals to reach energy  density needed for full-adoption seem achievable.
