One of silicon’s excellent qualities is that it absorbs ten times more lithium than the carbon currently used in lithium-ion [Li-ion] rechargeable batteries. The problem is that the silicon expands […]

Silicon electrodes, on the other hand, could theoretically hold up to 10 times more lithium than graphite and around 30 percent more electricity for that matter. The problem with silicon electrodes is that they swell when lithium enters them (the battery […]
