Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new lithium metal battery that can be charged and discharged at least 6,000 times — more than any other pouch battery cell — and can be recharged in a matter of minutes.
Prototypes suggest that solid-state batteries could store up to 80 per cent more energy than lithium-ion units of the same weight and volume. Lithium metal, which has a higher energy density, could take the place of graphite, helping to reduce battery weight and volume.
Improvements to safety and energy density without increasing the cost of battery packs, which are around $12,000 per car, have reached technical limits which means there is an inbuilt floor to the price for longer range cars using lithium-ion batteries. The entry-level Tesla Model 3 for instance starts at $37,990, the Hyundai Ioniq at $33,245.
Lithium-ion batteries and related chemistries use a liquid electrolyte that shuttles charge around; solid-state batteries replace this liquid with ceramics or other solid materials. This swap unlocks possibilities that pack more energy into a smaller space, potentially improving the range of electric vehicles.
Lithium metal, which has a higher energy density, could take the place of graphite, helping to reduce battery weight and volume. For those wishing to improve the performance of lithium-ion batteries, installing one with a weight in excess of 500kg on a moving vehicle — without compromising range and safety — is the onerous challenge.
Though battery research tends to focus on cathode chemistries, anodes are also in line to get a makeover. Most anodes in lithium-ion batteries today, whatever their cathode makeup, use graphite to hold the lithium ions. But alternatives like silicon could help increase energy density and speed up charging.
