Maxwell Technologies reports that it has more than doubled its ultracapacitor production capacity over the past year and is moving forward with its plans to increase output of its Boostcap line of ultracapacitors. To date, Maxwell has pumped out more than 15 million ultracaps, says David Schramm, the firm's president and chief executive officer, adding that "ultracapacitor sales having grown by more than 50 percent in each of the past two years and our expectation for continuing rapid growth going forward, we need to make sure we stay a step ahead of demand."

Maxwell Technologies touts its Boostcap line by saying that, unlike batteries, which produce and store energy by means of a chemical reaction, ultracapacitors store energy in an electric field. This electrostatic energy storage mechanism enables ultracapacitors to charge and discharge in fractions of a second, perform in a wide range of temperatures range and remain fully operational after a million charge/discharge cycles. Maxwell Technologies' capacitors can be found in hybrid transit buses across the globe and in Continental's stop-start system introduced last fall by PSA Peugeot-Citroen.

Total of More Than 15 Million Cells of All Types Produced to Date for Wide Array of Applications Worldwide

SAN DIEGO, April 12, 2011 /PRNewswire/ -- Maxwell Technologies, Inc. (Nasdaq: MXWL) reported today that it has more than doubled production capacity for ultracapacitor electrode, cells and modules over the past year, and is moving forward with additional capacity expansion to satisfy rapidly increasing demand for its BOOSTCAP® ultracapacitor products.

"The company has produced more than 15 million cells of all types since setting up initial high-volume production," said David Schramm, Maxwell's president and chief executive officer. "With ultracapacitor sales having grown by more than 50 percent in each of the past two years and our expectation for continuing rapid growth going forward, we need to make sure we stay a step ahead of demand."

Working with a contract assembly partner, the Company brought on line a new assembly line for its redesigned, high-volume, 350-farad "D-cell" ultracapacitor in the third quarter of 2010. Before moving D cell assembly, Maxwell had produced approximately 7 million D cells, mainly for wind turbine blade pitch mechanisms, at its Swiss production facility.

In collaboration with another contract assembly partner, the company recently completed installation of a second assembly line for its K-2 family of large cell products, and a third line is scheduled to be installed later this year. Maxwell produced its 2-millionth 3,000-farad large cell in January, and expects to deliver a third million by the end of this year. Large cells have been used mainly in hybrid transit buses for regenerative braking and torque assist, and the company is now supplying a 1,200-farad large cell to Continental AG, a global Tier 1 auto parts supplier, for a stop-start idle elimination system introduced last fall by PSA Peugeot Citroen.

A third contract manufacturer assembles Maxwell's HC family of small cell products, which range from one to 150 farads, and are used mainly in industrial electronics applications.

In December 2009, the company announced that it was expanding production capacity for its postage stamp-size, 10-farad PC-10 ultracapacitor cell to satisfy rapidly increasing demand generated by a new backup power application in solid state disk drives for enterprise computing systems. Previously, Maxwell had delivered several million PC-10s to power wireless transmitters in automated electric utility meters and other devices.

The proprietary electrode material used in all BOOSTCAP® cell types is produced only in the company's San Diego facility. Electrode capacity has been doubled over the past 12 months and will be re-doubled by mid-2012. The company also is evaluating proposals from economic development agencies in several adjacent states for location of a second electrode facility it plans to outfit and bring online in the second half of 2012.

Unlike batteries, which produce and store energy by means of a chemical reaction, Maxwell's BOOSTCAP® ultracapacitor products store energy in an electric field. This electrostatic energy storage mechanism enables ultracapacitors to charge and discharge in as little as fractions of a second, perform normally over a broad temperature range (-40 to +65C), operate reliably through one million or more charge/discharge cycles and resist shock and vibration. Maxwell offers ultracapacitor cells ranging in capacitance from one to 3,000 farads and multi-cell modules ranging from 16 to 125 volts.

      Electrostatic ultracapacitors (nanosecond response time) combined with electrochemical nanobatteries (20 millisecond response time) truly are the way of the future. Capacitors provide the instantaneous pulse power while batteries serve more as the energy storage. Optional integrated solar cells provide added comfort to slow, yet nearly infinite mileage.

      Both have the abilities to perform in range of temperature beyond any fuels (-40 to +65C). Capacitors have 1+M and batteries 10+K cycles (50 Ah: 9K full cycles to 90 % capacity at 100 % DOD cycle test suggest at least 18K to 80 %) with no shock or vibration troubles. As the press release states, capacitor cells are also available from 1 F to 3 kF and capacitor modules are available from 16 V to 125 V (up to 1.5 kV in series).

      Sorry for all the numb3rs.

      Wake me up when they've produced a KILOFARAD capacitor. That's about what it'll take to compete with battery technology.
        • 7 Months Ago
        I should add that of course it has to weigh the same. increasing the capacitance is easy enough simply by paralleling multiple
        • 7 Months Ago
        your sentiment is correct but they have been at 3kF for years : )

        the energy in a capacitor i E=.5CVV where V is voltage and C is the capacitance in farad so it's a combination of farad and voltage spec.
        at that voltage they would need to get up to at least 30kF (~60Wh/kg) to be considered as a replacement for batteries and more likely will need to get to 60kF to really compete.

        but midway can be interesting for a small pack just for capturing hard braking energy which current battery tech is not so good at. it would be elegant to almost completely do without mechanical brakes. only a small backup brake to serve as emergency and parking brake and that can be attached to the driveshaft inside the car so we don't have any clutter at the wheels.
        that's yummy

        come to think of it, that should probably be done right away for the cars that have motor power great enough to match emergency braking and then just dump the excess energy into a resistor until such time ultracaps are suitable for it.
        we don't need no stinking disc brakes : )

      Well, finally a reasonable article on autogreen ... would be nice if you explained why this is important technology ?

      For the less curious one of the reasons these ultracaps can be helpful in the near term is that they allow EV's to more effectively use their existing battery technology and they make storing regenerative energy much more efficient ... one of the biggest drains on a battery is accellerating the car up to speed ... it drains a battery faster than pulling the same amount of power out over a longer period of time ... ultracaps can help to handle these surges without draining the battery as fast ...

      so these ultracaps could be in use in many of the current production EV's in the near future ...

      attempting to REPLACE batteries with ultracaps is just not going to happen, possibly ever ... but thankfully they don't need to ...

      • 7 Months Ago
      we probably need at least a doubling of specific energy though as well as significant reduction in price from the current ~50k$/kWh for them to be relevant
      • 7 Months Ago
      I get the feeling that they need a little more competition. They are not pushing to bring new tech to market and are already just working on economies of scale. That's not a bad thing short term, but there are a number of breakthroughs that have happened in supercaps that increase both their energy and power densities and they are ignoring them.

      I am hoping pressure from Ioxus and others will start to up the ante....and hope they all wildly succeed!

      It is generally seen as a poor idea to discharge them in 'a fraction of a second'.

      First rule - if somebody tosses something at you in the electrical lab, don't catch it.
