China’s Sept power and other battery output hits 237GWh, up 57% YoY

The deceleration from above-60% growth to 57% is the more telling signal than the headline figure: China's battery buildout is still expanding at a rate most supply chains would envy, but the direction of travel has changed. The cited drags — soft power-battery demand and an export tax rebate adjustment — point to policy and end-market factors rather than capacity constraints, which matters for anyone tracking global battery oversupply and pricing pressure. Whether the sequential slowdown deepens into a sustained trend, and how export volumes respond to the rebate change, is the open question.
