Early in 2014, Robert Bosch and GS Yuasa Corp. established joint venture Lithium Energy and Power GmbH & Co. KG with a target to double energy density of lithium-ion batteries and lower the costs by half, by 2020.

According to Automotive News Europe, they are progressing.

Udo Wolz, president of Bosch’s subsidiary in Japan said:

“We are on a good path to reach that target.”

Of course, they didn’t disclose the precise number they are aiming for – maybe 500 Wh/kg, if we use some 250 Wh/kg on the cell level?

Second part of the article is about batteries for mild-hybrids. On this front Bosch would like to use low-voltage 48 V systems.

“The key to capping costs in Bosch’s mild-hybrid system is a small, low-voltage lithium ion battery. It is only 48 volts, compared with the 220-volt battery in the Toyota Prius hybrid vehicle.

Bosch says its technology, when used with a standard gasoline internal-combustion engine, improves fuel efficiency by 5 to 18 percent. It did not specify the cost.

Bosch’s 48-volt battery powers an electric motor that can assist the car’s engine in powering the wheels or keep the car’s electronics and climate control going during stop-start mode.”

Curious that Yuasa is talking about 2020 not 2017 for its next generation cell.
It would be useful to have clarity on the energy density of the current Yuasa LEV50 cell. This is used in the iMIEV, which surprisingly has not had a capacity increase, so it is still only 16kWh while the Volt battery has increased from 16 kWh to 18.4 kWh for 2016.
A quick google search reveals an old page of specs for the Yuasa LEV50 which lists the energy density in 2009 at just 99WH/kg:
If Yuasa double from 99 to 200WH/kg by 2020, that would be very disapointing.
The iMIEV would be a lot more practical with a 32kWh battery; it needs a battery upgrade now, not in 2020.

Having little market cap makes it much harder for a small company like Mitsubishi Motors to spend much on R&D.

Hard to get excited about what a battery company says it might be able to do in five years, especially given the extreme level of complete B.S. in claims from the battery industry.

Even if there is a 0% B.S. level here, five years at the current rate of development is too long to be able to predict what will already be on the market when they’re ready to go into production.
