Abstract
Electrodes made with a matrix selectively loaded with particular active particles provide uniform distribution and reduce issues due to particle expansion. The electrode has a current collector, a separator and a matrix having first pores having a first size and second pores having a second size, the first size being larger than the second size, the second pores being uniformly distributed throughout the matrix; first active particles deposited in the first pores, the first active particles having a first particle size smaller than the first pores and larger than the second pores; and second active particles deposited in the second pores, the second active particles having a second particle size smaller than the second pores.
