Just wanted to post this in the news and saw it here. Interesting quotes: The facility’s Li-ion production line operates at about 50% of capacity, producing around 100,000 units annually separate from its NiMH lines. Before expanding Li-ion production outside of Japan, Primearth will add a second Li-ion line in 2019 at its Taiwa plant with an expected capacity of 200,000 units Currently Prime batteries are made by Panasonic, but will be made by Primearth by the next decade. In 2016 Toyota produced 920,000 NiMh batteries and 520,000 Li-ion Apparently Panasonic still produces a large amount of Li-ion batteries for Toyota, but only until Primearth expands production capacity.
