Tesla has excited markets with the type of battery technology it is about to reveal.
However, a study published ahead of the event shows that the US is lagging behind its global competitors, particularly Japan.
The study by the European Patent Office and the International Energy Agency found that the US ranked fifth in battery technology patents from 2000 to 2018. The US followed Japan, South Korea, Europe and China.
Tesla actually supports that the US is lagging behind
himself. Elon Musk, Tesla's chief executive, tweeted that the company would increasingly use batteries from Japan's Panasonic
South Korea's LG Electronics
and China's CATL

One area the U.S. is strong in is potential next-generation batteries, the study said. The US leads the way with 36% of the patents on lithium-nickel-cobalt-alumina chemistry for Li-ion batteries already used by Panasonic and Tesla.
The USA follows only Japan in patents for solid-state Li-ion battery patents and is the leader with almost a third of all patent applications for redox flow batteries.
Panasonic, LG Electronics, Toyota
and Bosch had filed the most patent applications between 2000 and 2018.
