The radius of spatial analyticity for solutions of the KdV equation is studied. It is shown that the analyticity radius does not decay faster than t− 1/4 as time t goes to infinity. This improves the works of Selberg and da Silva (2017)[30] and Tesfahun (2017)[34]. Our strategy mainly relies on a higher order almost conservation law in Gevrey spaces, which is inspired by the I-method.
