Balqon Corporation introduces HIQAP industrial lithium-ion packs to replace lead-acid batteries

Green Car Congress

Balqon Corporation, a developer of heavy-duty electric vehicles, drive systems and lithium battery storage devices, has introduced high-capacity lithium-ion batteries as an alternative to the current industrial deep cycle lead acid batteries. HIQAP lithium battery packs are designed to support large daily loads requiring deep depth of discharge and high energy transfer efficiency for solar, micro-grids, off-grid storage and telecom applications.

Study sees gradual, focused replacement of lead-acid SLI batteries by Li-ion batteries over next couple of years

Green Car Congress

The advantages of a lithium-ion SLI battery would primarily be in terms of its longer cycle-life and weight reduction when it is considered as a ‘drop-in’ replacement option for the existing lead-acid battery, which has dominated the SLI application market for the last 100 years. The researchers considered aspects of safety, cost, design and testing specifications n light of the emerging European battery legislations on the use of restrictive materials in vehicles.

Green Car Congress

The graphene cage acts as a mechanically strong and flexible buffer during deep cycling, allowing the silicon microparticles to expand and fracture within the cage while retaining electrical connectivity on both the particle and electrode level. The chemically inert graphene cage also forms a stable solid electrolyte interface, minimizing irreversible consumption of lithium ions and rapidly increasing the Coulombic efficiency in the early cycles.
