These copies of batteries reflect the development of lithium-ion batteries. Akira Yoshino played a pivotal role in this development.
The cylindrical battery, from 1985–1986, was the first lithium-ion battery that was produced for user evaluation. The battery had a cathode of LiCoO2, and a carbon anode.
The prismatic battery is a lithium-ion battery for mobile phones from 2000–2010.
The thin battery is a laminate battery for a smartphone from 2019.
