Sodium-Sulfur Batteries. The sodium-sulfur battery consists of molten sodium at the anode, molten sulfur at the cathode, and a solid electrolyte of a material that allows for the passage of sodium only. For the solid electrolyte to be sufficiently conductive and to keep the sodium and sulfur in a liquid state, sodium-sulfur cells must operate at 300°C to 350°C (570°F to 660°F). There has been great interest in this technology because sodium and sulfur are widely available and inexpensive, and each cell can deliver up to 2.3 volts.

A 6 volt lead storage battery contains 700 grams of pure HjSO/fJ dissolved in water. 

Ey and E2 are the indicator electrodes. These may consist of a tungsten pair for a biamperometric end point for an amperometric end point they may both be of platinum foil or one can be platinum and the other a saturated calomel reference electrode. The voltage impressed upon the indicator electrodes is supplied by battery B (ca 1.5 volts) via a variable resistance Rs N records the indicator current. For a potentiometric end point Ey and E2 may consist of either platinum-tungsten bimetallic electrodes, or Ey may be an S.C.E. and E2... 

A simple apparatus suitable for this procedure is shown in Fig. 16.17. B is a 3 volt torch battery or 2 volt accumulator, M is a micro-ammeter, R is a 500 ohm, 0.5 watt potentiometer, and E,E are platinum electrodes. The potentiometer is set so that there is a potential drop of about 80-100 millivolts across the electrodes. 

Small-format lead-acid batteries with immobilized electrolyte are still used in some applications such as hand lanterns. Low-cost six or twelve-volt batteries (e.g. 6 Ah size) are used in child-driven toy cars and other sizes in emergency-light or alarm systems, kept on trickle-charge. Efforts are being made to produce bipolar systems which give 30 percent improvements. 

With the appropriate choice of electrode material, lithium batteries can be tailored to almost any application requiring cell voltages in the range of 1-3 V and current densities from a few tiA to tens of mA per cm. In addition, the change of potential with state of charge can be controlled from almost 0 V in the case of VSe2 to more than a volt for TaS2.

Hybrid conversions have not been common, since they are twice as complex as electric conversions. But in 1979, Dave Arthurs of Springdale, Arkansas, spent 1,500 converting an Opel GT into a hybrid that got 75 miles-per-gallon, using a 6-horsepower lawn mower engine, a 400-amp electric motor and a bank of 6-volt batteries. Dave Arthurs continued building hybrids into the 1990s. One of these conversions was a 99 miles-... 

A typical 100-cm silicon cell produces a maximum current of just under 3 amps at a voltage of around 0.5 volts. Since many PV applications involve charging lead-acid batteries, which have a typical nominal voltage of 12 volts, the solar modules often consist of around 36 individual cells wired in series to ensure that the voltage is usually above 13 volts which is enough to charge a 12 volt battery even on overcast days. 

The Myers NmG three-wheeled electric car has a top speed of 70 mph. It is a single seat, three-wheeled electric car that runs on 156 volts DC with thirteen 12-volt batteries in series. It has a 1350 pounds curb weight with a 30-60 mile range and a price of 15,000- l7,000. 

Global Electric Motor s two-seat GEM car is a NEV, with a top speed of 25 mph and a curb weight of 1100 pounds with batteries. A 72-volt shunt GE motor is used with front wheel drive. Six 12-volt deep-cycle batteries are used with hydraulic brakes, independent front wheel suspension, rack and pinion steering, aluminum welded space frame and composite and thermoplastic body. It seats two or four with a price of 7,000 to 9,000. 

Ford s Think NEV came in two and four passenger models with a range of 30 miles. It had a 72 volt battery with a 5,000 watt DC motor. The charging time was 4 to 8 hours and it had regenerative braking with hydraulic drum brakes. The price range was 8,000 to 10,000. 

The Gorilla NEV is a 36 volt, 20-25 mph vehicle that uses three 12-volt batteries. It includes all required safety equipment for legality in California and 32 other states. 

India s Reva EV can travel at about 35 mph. The power system is eight 6-volt EV type lead add batteries. The dent-proof body panels are made of high impad ABS (acrylonitrile butadiene styrene). It has side impact beams and electronic regenerative braking. The suspension is McPherson struts in front and coil springs in the rear. It is a two-door hatchback that... 

The eleotrolysis is carried out in a medium-sized filter jar two moderately thiok oarbon rods serve as electrodes. The oathode dips into the solution, the anode into 2A7-sulphuric acid contained in a small porous cell, which also dips into the liquid. The eleotrodes are fixed a short distanoe apart and the current is obtained from two units, arranged in series, of an aooumulator battery of the usual capaoity. At a potential difference of 4 volts 1-5-2 amperes pass through the solution.
