GS Yuasa Promises Range-Doubling EV Battery By 2020
That's the promise that's been coming from GS Yuasa for several years. The thinking being that higher-energy dense lithium-ion batteries will lead to high increases in range.
A recent Nikkei article again warms up to those promises.
The goal for the Japanese battery manufacturer is the apparent doubling of battery capacity (and therefore electric car range while displacing the same area and weight). Mass production of these "breakthrough" cells are set for as early as 2020…so apparently it isn't a thought-bubble, or lab experiment of a new, unproven technology.
GS Yuasa through joint venture Lithium Energy Japan supplies batteries for Mitsubishi i-MiEV (16 kWh) and Mitsubishi Outlander PHEV (12 kWh).
The problem is that there are no firm numbers in the article. Doubling the first generation cells in say a plug-in Mitsubishi would only match the top players today, not pass them.
