That idea is basically unworkable Harry. Such a battery would need a huge capacity to be much use, and it would be cycled quite rapidly so life might be poor. A battery with a capacity of say 100GWh would have an immense energy density and be extremely dangerous. Some battery capacity might help to smooth the wind output, but again would be cycled quite quickly. A very large flywheel might be good but again would be rather risky. Connecting the turbine to the grid with a pile of electronics would improve control, but add a considerable degree of cost, which would make the wind supply less attractive.
