Will Future Tesla Cars Use Metal-Air Batteries?

Tesla Model S

Most and industry analysts expect batteries to dominate electric-car storage for the rest of this

But is Silicon Valley startup Tesla Motors [NSDQ:TSLA] to add a new type of battery to increase the of its electric cars?

The high-end Tesla Model S with an lithium-ion battery pack is at 265 miles of range.

(Real-world can be lower, depending on a number of including temperature, speed, and style.)

8 patent applications

But as a commenter on the Motors forum and a recent on the stock investing site have noted, Tesla has for eight separate patents on of metal-air battery technology.

Two of the names on the application are JB Straubel, chief technical officer, and Kelty, its lead battery

The metals covered for use in the metal-air are aluminum, iron, lithium, vanadium, and zinc.

The application’s includes the following summary:

A of optimizing the operation of the power of an electric vehicle is provided, the power source is comprised of a battery pack (e.g. a battery pack) and a second pack (e.g. a metal-air pack).

The power source is optimized to use of the least efficient battery (e.g. the second battery while ensuring that the vehicle has sufficient power to the expected travel distance the next battery charging

The second battery pack may be to charge the first battery or used in combination with the battery pack to supply power to the electric vehicle.

Mounted in a demonstration car, Phinergy’s battery provides 1,000 of range. it said, and requires of distilled water (which as electrolyte in the cells) about 200 miles.

Production in 2017?

Phinergy CEO Tzidon told Bloomberg Elliott Gotkine last that his company has signed a with a global automaker to the battery in production volumes, in 2017.

He didn’t name the and Tesla does not say much its future products (occasional from its CEO Elon Musk

But for Tesla, combining the acceleration by a lithium-ion battery with the range offered by a consumable battery might permit vehicles that offer the of the Model S with even range when needed.


We can anyhow.
